USGS GetElevation webservice

Ketch — Mon, 05 Jan 2009 20:59:04 GMT

While in Manifold, I have an interest in obtaining elevation data for point data and was wondering if anyone has utilized the USGS GetElevation web service. If so, would you be willing share your method(s) or techniques.

Thanks!

Problems Reprojecting a Surface

miken — Tue, 30 Dec 2008 08:59:53 GMT

I'm trying to reproject a surface. I have drawings that are in the projection that I would like to use and they have no local offsets for the x and y. However, when I try to reproject my surface the computer automatically puts in the local offset in the X and Y. I have tried different settings in the projection window, only to get the same results. Ultimately, I want to export the surface as a grid to be imported into a program that cannot reproject data. So I need the data to be in a projected XY. Even if i do a simple ascii grid, it puts in the unprocted coordinates. What am I doing wrong, or is there an easy way to generate a grid with projected data.

Thanks for any help.

Concave hull

tjhb — Mon, 29 Dec 2008 19:50:50 GMT

Something we've been trying to do for a while. This seems to work and is simple. Please criticise.

The method is:

Create a triangulation of the point set, splitting the result into individual triangles.
Create a concave hull of the point set.
Cull triangles touching the boundary of the concave hull exactly twice.

-- SQL

SELECT UnionAll([Triangle]) AS [Concave hull]

FROM

(SELECT [Triangle], Count([Coord]) AS [N]

FROM

(SELECT [Triangle]

FROM

(SELECT AllCoords([Geom (I)]) AS [Points]

FROM [Drawing] WHERE IsPoint([ID])

)

SPLIT BY Branches(Triangulation([Points])) AS [Triangle]

)

LEFT JOIN

(SELECT [Coord]

FROM

(SELECT AllCoords([Geom (I)]) AS [Points]

FROM [Drawing] WHERE IsPoint([ID])

)

SPLIT BY Coords(ConvexHull([Points])) AS [Coord]

)

ON Touches([Triangle], [Coord])

GROUP BY [Triangle]

)

WHERE [N] <> 2;

The extra wrap using WHERE is used because I can't get HAVING to work (suspecting a bug).

Geo-referencing scanned image files

bgaber — Sat, 27 Dec 2008 11:04:32 GMT

I have been having difficulty geo-referencing an image file. How many control points are necessary, and does anyone have a preferred method? When I do a large number of control points, the image loses all it's resolution and get's blurry. I am trying to do lakes, and they have irregular shapes. I have the best luck maintaining the images resolution using only a couple of points, and the simple. This doesn't give me a good fit across the whole image, though.

Thanks for any assistance, as always...

IMS development resources

clearviewgis — Mon, 05 Jan 2009 07:41:31 GMT

I have a working IMS up and running, but I want to develop more features. http://maps.clearview.ca

Can anyone suggest some books or resources to help with development of tools for the IMS?

I was thinking of a good ASP, HTML and Java Script book.

I have almost no programming experience except in SQL and VBA, so I feel like I should start from the beginning and work my way up.

Let me know.

IMS imgery display issue - sql linked imagery

schiggi — Tue, 23 Dec 2008 07:50:31 GMT

Hello,

Sorry if this gets double posted. I have an IMS site that is supposed to display some imagery that is stored in and linked from SQLServer. But does not display them.

I'm pretty sure I have IUSR_WWW set to all the correct folders/files, and within the SQL tables. I reset the Data Cache folder location, and gave it appropriate permissions, as per an older thread I had perused regarding similar issues.

But for the life of me I cannot get the imagery to display in the IMS. Any ideas?

Linked ECW moving for certain zoom levels

SeaTrails — Thu, 18 Oct 2007 17:48:03 GMT

Linked ECW still moving around when in a map. For certain zoom levels, linked imagens (ECW) moves from its position, making everything with digitizing vectors over images very very difficult.

Anyone else with this behavior?

same behavior running M8 last release on different machines with Win XP (x32 and x64).

Manifold files not showing the Manifold icon

lovelace — Sat, 03 Jan 2009 13:03:20 GMT

A small but annoying problem... After a new re-install of the XPpro & applications including Manifold and VS2008 I can’t get .map files to show the Manifold icon. I’ve associated all map extensions to be opened with Manifold and they all open just fine, but explorer still insists on listing them as “linker address map” under ‘type’ and giving them a boring looking icon. Any ideas? Thanks in advance.

ExportDrawing method

mdsumner — Tue, 20 Nov 2007 11:42:29 GMT

I am getting an "invalud argument" error on the following VB.NET code:

mDrawing = gComponentSet.Item(gComponentSet.ItemByName("TempDrawing")) mDSource.ExportDrawing(mDrawing, "Exp_Drawing", mDrawing.TypeName)

which appears to be related to the drawing type (3rd argument). I checked the help files but cannot find any examples of that the proper values are for the mDrawing.TypeName argument. I have tried "Drawing", "Point", "PointDrawing", and the TypeName from the Drawing component itself.

Thanks for the help!

linked image update

atomek — Sun, 04 Jan 2009 05:27:26 GMT

I am doing a project that doesnt have much to do with GIS but Manifold seems to be the only tool. But still there is a problem which I explain and hope someone can help.

I have a camera (webcam) that updates an image every 10 seconds. In that time I put points on a drawing layer where features appear and then I want to update my image so I can digitize the refreshed view from camera. The problem is that when I have a linked image in my project panel it doesnt update fast enough (I tried to close/open the image to see if it updates and it does once for few minutes). Can I have a query that takes the image from my hard drive and link an image to that query so the refresh can be made with a mouse click (refresh data/ alt+F5)? is there any way to have my image updated in Manifold?

IMS Background color change

Donmap — Sun, 04 Jan 2009 03:35:04 GMT

Hello all and Happy new year!

Is there way to change the background color in the IMS?

I know you can do it via the Manifold professional program settings, however, if you want the background color to chage in a IMS is there a line of script that you can change or write that will create the desire effect?

Enterprise spatial databases - do any support global grids and non-cartesian geospatial gridpoint/cell indexing

Nick Verge — Fri, 02 Jan 2009 12:06:04 GMT

I am working on some new feature suggestions based on a future version of Manifold being able to support Gaussian global grids and the Isocahedral Snyder Equal Area Aperture 3 Hexagonal (ISEA3H) geodesic discrete global grid. To help with this, I would be grateful if anyone who is familiar with the major enterprise database systems could answer the following for me:

Do any of the major enterprise databases provide support for these or any other kinds of non-planar global grids, together with the non-cartesian spatial gridpoint/gridcell indexing these require? if so which kinds of global grid? if you can direct me to any documentation, the better.

I have had a look at the white paper on the Oracle 11g Georaster model and cannot see any mention of it supporting anything other than planar grids and cartesian spatial indexing. I am hoping someone will be able to confirm this about Georaster and hopefully the give information on this wrt database products from other vendors. I doubt any do, but it would help to know this for sure.

Support for Gaussian global grids, ISEA3H and perhaps also triangular GDGGs by a future version of Manifold would provide the basis for it to provide some very cool new features and perform operations, currently very difficult if not impossible in most commercial-off-the-shelf GISs. If these and other forms of global grid were supported by the major enterprise database products, it could make providing global grid support in Manifold a whole lot simpler and provide standard around which new features could be provided. Hence my question.

If you are not familiar with Gaussian global grids and ISEA3H geodesic discrete global grids, why they are so useful and essential for some purposes, then this is this weeks homework. ;-)

Thank you for your help.

Scale Escape Sequence Fix

BCowper — Fri, 02 Jan 2009 12:26:10 GMT

From the latest update:

(Fix) Scale escape sequences used in text layout elements correctly truncate scale values to the desired number of decimal digits.

If I create a View set to 1:1,250 scale, the scale escape sequence in the layout still displays the incorrect value of 1:1300 regardless of the number of decimal digits I specify. What does this actually fix?

Linked drawings from linked tables or queries

chris lang — Fri, 26 Dec 2008 04:41:39 GMT

Good morning,

How can I create linked drawings from linked tables, or queries from linked tables, in Manifold ?

I've got 3 tables in a Manifold project, linked from an .mdb database. 2 of them are geocoded ( on containing points coordinates, the second containing lines defined by coordinates, Line ID, Line Order, like the example in the Manifold User Manual ). I will also use queries on these 3 linked tables, from which I want to create a linked drawing.

Thank you for your help,

End If

End Sub

this code opend an message with the object Id selected.

i am able to load the drawing table into form and view the record...

Add Objects in an ACCESS-Table

volker — Wed, 31 Dec 2008 03:44:17 GMT

I have problems to add Objects to a drawing that is stored in an Access-Table.

Look the screenshoots in the attachement.

Add Points to the Drawing works, until i go out of the Drawing. I get an error „Can`t add object“.

It seems the Drawing is limited about a „Virtual Box“ of coordinates around the Drawing.

Is there a possibility to do this, without to store the Drawing in a real Database, or making a

"virtual" box (border lines, area, etc.) that is big enough for my Area of interest to add objects ?

Damn, i can`t get away the <!.....>, sorry.

Export line drawing to SQL Server 2008 fails

Norris Evans — Thu, 18 Dec 2008 12:05:20 GMT

When I attempt to export a simple drawing containing line geometries, get the message in a Manifold dialog stating "The statement has been terminated". Always get the same message when attempting to export a number of different drawings and no matter what options are selected in the export dialog - do not reproject data, create spatial index create sequences or triggers.

Am running 8.0.10.0 in 64-bit mode in Windows Vista 64 against Microsoft SQL Server Management Studio 10.0.1600.22 ((SQL_PreRelease).080709-1414), connecting to the database using integrated security.

Any clues?

Problem connecting to postgres from .HTA application

t-crow — Fri, 19 Dec 2008 14:06:50 GMT

Hello,

i'm at it again with more questions for the ready and willing.

okay, so i have this script which connects to postgreSQL database and imports drawings at multiple points during its execution. it was working perfectly.

i thought it would be neat to add a UI for it as there are some choices to be made before it can be run, so i wrapped it in an HTML Application (HTA).

now, for some reason, it doesn't want to connect to the database anymore. i have researched the issue to the fullest extent of my abilities and now must call out to the tech savvy.

when run from the HTA wrapper, the following code throws this: ERROR: Cannot connect to the data source

SET ds = doc.NewDataSource()

ds.ConnectionType = "PostgreSQL"

ds.ConnectionString = "host='myHost' port='5433' user='tcrow' password='myPwd' dbname='myDB'"

ds.importDrawing("public.tableName.geometry")

if i change the above code to the following it throws this: ERROR: relation "GDB_GeomColumns" does not exist; Error while executing the query

SET ds = doc.NewDataSource()

ds.ConnectionType = "ODBC"

ds.ConnectionString = "Dsn=PostgreSQL30;database=myDB;server=myServer;port=5433;uid=tcrow;pwd=myPwd"

if ds.probe then

ds.importDrawing("public.tableName.geometry")

end if

the server logs confirmed that with the latter code, i was connected. also, i noticed and confirmed that this error "GDB_GeomColumns" is thrown regardless of a successful import, for reference see this thread http://69.17.46.171/forum/t68848.7. i dunno. the script worked great as a standalone .vbs, the ONLY thing that has changed is that the code is now executed on button's on_click event in the HTA application.

HTA leverages IE to provide a graphical user interface but runs in a seperate process called mshta.exe

i also get the same result when having the .hta launch a .bat file which in turn launches the original vbs file

so question 1 is: regarding the first code, what would keep me from connecting to the database?

question 2: regarding the second code, once connected, what would keep me from importing the drawing?

question 3: is the problems with the hta, what about the hta would prevent this?

Is NAD83 HARN supported in Manifold?

rfriedman — Thu, 12 Jun 2008 16:10:48 GMT

I have data in State Plane, NAD83 HARN (HPGN), New Mexico West. I wanted to project it to NAD 83, but wasn't able to find any support for NAD83 HARN in the projections list. The difference between NAD83 and NAD83 harn is a little over a foot for our area. Am I missung something, or do I need to send in a request to Manifold?

I can do the reprojections with ArcGIS, but would prefer to have it directly available in Manifold.

Thanks in advance,

"higher-order" parameter queries

rk — Tue, 16 Dec 2008 02:05:03 GMT

Hi,

Manofold allows parameter queries. From documentation(emphasis mine):

[It] can use the parameters to substitute any value within the query. [It] cannot, however, use the parameters to substitute names of columns or tables, or to specify functions or operators.

What do you think of going a bit (actually much) further and allow table- and column names (even functions) to be parameters? I imagine, that a drop-down list of available tables/columns can be provided to user for substitution of such "higher order" parameters.

It's like dynamic SQL creation and execution, only in more user-friendly way. Are there any technical difficulties involved? I cannot see many. Of course the created SQL can fail with type error, but there's no harm done.

I can imagine many applications of such generic kind. Powerful, relatively easy to define (having already the powerful functions/operators of Manifold) and very easy to use. In fact I think of every transformation from Transform Toolbar as one such generic (ie it accepts any drawing/table) operation. The implicit arguments in the latter case are Target and/or Selection. Isn't it so?

Newbie has problem with Layouts

mike s — Mon, 29 Dec 2008 06:59:14 GMT

I am unfamiliar with layouts, but did read the manual. It says:

"We drag and drop items into a layout from the project pane. Begin by double clicking on the layout component to open it in a project pane. We can now click on an item in the project pane and drag and drop it into the layout window. Components that are dragged and dropped into a layout will at first appear as a fairly small layout element so they do not obscure other elements in the layout. Click on the component that's just been dropped to select it and then resize and reposition the element as desired."

But how do we resize and reposition it? All that I get is a red selected square. Should I see little resize handles

on the object so I can move it around? Once I drop it onto the layout I can't do anything else to it. Obviously

I am misunderstanding something in this tutorial.

Postgresql & ims trouble :S

Gustavo Palminha — Sat, 06 Dec 2008 16:36:43 GMT

Hello to all.

I've been facing a strange issue when serving an ims application that gets data from postgresql.

The problem is that my ims application has a few linked postgresql tables and when using the application, manifold does not refresh them, so nothing shows up in the map.

When working inside the map file i can connect to postgresql using the database console without any problem and retrieve the data. Or in other words, by just opening the map file with manifold the program will refresh the data and load all components, but for ims application this does not happen.

I've checked the iusr permissions and all were fine, and i even tried to connect to postgresql using different data sources like the manifold's postgresql data source, ado.net odbc and odbc which allowed me to get the data but only from inside the manifold (lastest version) GUI application.

What could be wrong?

Regards.

How to calculate/convert track lengths

Phil — Fri, 26 Dec 2008 03:08:12 GMT

How to calculate track length ? I have created a linked line drawing from a set of geographical positions

and revealed the hidden columns in the related table.

One of them is titled "Length(I)", and I believe should give me the length of the line.

However the values I get are not sensible (too small) since the animals have travelled several hundreds

or thousands of km and my results are all under 100.

So I presume there must be some sort of unit issue, but i don't know how to convert these values into meters

or kilometers. My line drawing is in Lat/lon projection and the map I am using is in Albers Conical projection.

I have attempted to use queries and scripts found on the Manifold website, but nothing has worked so far ...

Any ideas ? Thanks a lot !!!

ArcSDE?

rheitzman — Mon, 22 Dec 2008 15:54:22 GMT

I've finally been able to get the magic beans to connect to our downtown ArcSDE server. I have a connection in my data sources. The Administrator Console lists the drawings present.

When I try to link or import the data source I set a set of drawings and a set of tables - not one combined layer. The imported drawing has no attributes or key fields. The attribute table does not have a key field that cam be used to link to the drawing. I can combine the records in using the ordinal but that doesn't seem like a good idea.

I must be doing something wrong.

How to I import a drawing from ArcSDE and have the drawing layer and attributes automatically joined?

SQL Linked Drawing Query woes

Ross — Wed, 24 Dec 2008 02:21:36 GMT

Hi, I am having trouble running a query set up in Manifold from within my web application. The setup in Manifold is a linked drawing ('Accidents') to an external SQL database. A query is set up called 'SelectAccidents' which interrogates this drawing for matches. A second linked drawing is created that is linked to the result of the query and is a layer within my map.

In Manifold, I can run the query and then refresh drawing2 to see the results in the map. When I try and run this in my web application, I get nothing returned. The Accidents drawing used to be a static table and this worked fine. It is only since I have been trying to use 'Accidents' as a linked table to SQL that I have been having problems. The Below is the snippet of code I am using and I would appreciate any thoughts or ideas anyone has:

[code]

else if (command == "query") {

var TempDataset1 = mapserver.Document.ComponentSet("Drawing2");

mapserver.Query("SelectAccidents", queryPars, true, true);

TempDataset1.Refresh();

Copy/paste surface to image and back without loss of height value decimal places

dale — Mon, 22 Dec 2008 21:01:36 GMT

Merry Christmas to you all!

I've been working on adding a sea surface to a coastal LIDAR DEM so as to overlay some aerial imagery on a terrain. In a typical Manifold way I found a couple of ways to do this.

However in my trials, I found I could not copy and paste the DEM from a surface with values to two decimal places ( no pallete and no hillshading) to an image and then copy that image and paste back as a surface without losing the two decimal places.

Is this a restriction on the levels of greyscale that the no pallete DEM has when pasted as an image? I tried pasting as a range of integer values (32 bit - 64 bit etc) but my DEM always pastes as a surface with one metre steps.

Cheers

Script runs paging file out

firsttube — Tue, 23 Dec 2008 05:50:05 GMT

I have a script that runs in manifold after I leave for the day. Basically, it updates all the drawings in other manifold projects that are used in an IMS. Recently, the script has been failing. The error that is given by manifold is "No memory". When I click OK, the error pops again. Then I click OK, and it does not come back. But a new error "The memory could not be referenced..." comes. After click through these errors, manifold shuts down.

When I check task manager, all seems fine. The paging file is low, and CPU usage is nil. Now, if I run the script while I'm here and watch the task manager, I notice that the Paging file usage steadily increases. And the amount of RAM used by manifold increases as well. I'm thinking that eventually, the script uses all of the RAM and paging file, and that's where the "No memory" error is coming from? I have the paging file set to 8000/8000. I have 4 GB RAM, Windows XP pro SP3.

Is there any way to prevent this from happening? Now this is a recent development on my system - it never used to happen, so there may be a configuration change that I'm unaware of. I recently had a string of malware removed, and I'm not sure if this could cause a problem like this.

I was looking in the Registry under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\. Could any of these registry values be modified to solve this problem?

thanks

New data file format support proposal - support for import/export of data in GriB1 & GriB2 (Gridded Binary Format)

The following is part of new feature request I will be submitting shortly to Manifold.net, posted here for your amusement and discussion

Support within Manifold System GIS for import and export of arrayed environmental data in gridded binary (GriB) format

It is requested that a future version of Manifold System be able to import and export information in Gridded Binary (GriB) format.

GriB (Gridded Binary Format) is a well-documented file definition standard administered by the World Meteorological Organisation (WMO) and used to allow efficient distribution of often large volumes of multifield, static or time-varying 2D or 3D arrayed ("gridded") scientific information about the natural environment.

GriB in the form of GriB1 was initially developed as a file standard by the World's major weather forecasting centres as a means of efficiently transmitting observational data about the atmosphere (including satellite remote sensing data) and/or the output of numerical weather prediction modelling. As such what is now known as GriB1 was probably the first, or one of the first, standard geographic information file formats, albeit one for what was originally a small community with access to supercomputing facilities.

Latterly, the GriB1 format has been found to be deficient and a successor format, GriB2 was concieved. As a result GriB2 is now used to distribute a wider range of information. GriB2 is now routinely used to distribute in addition to information about the past, present and future state and behaviour of the atmosphere, information about the state of the oceans, the soil, snow, ice and vegetation cover. Importantly, much such information can only be obtained in GriB format.

For any scientist or other professional who needs to study or monitor the atmosphere, the oceans, vegetation cover, soil properties the hydrosphere and the natural environment in general, with the aid of a COTS GIS, support for reading and writing information in GriB1 and GriB2 format by their GIS is essential. For this reason, I recommend that a future version of Manifold, provide the ability to import and ideally, also export, data in GriB1 and GriB2 formats. Providing this capability would enable a wider usage of such information, otherwise not easily imported into conventional COTS GISs at the current time.

GriB format documentation can be found at the URL below:

http://www.wmo.ch/pages/prog/www/WMOCodes/GRIB.html

GriB is a flexible file standard. As such, GriB files produced by one organisation need not be indentical in content to files produced by another. Fortunately there are not many organisations producing data in GriB format. The largest is the USA's NCEP (National Centers for Envionmental Prediction), the umbrella organisation ofthe US national Weather Service, NOAA, National Hurricane Prediction Center, Storm Prediction Center etc).

Information about the GriB products produced by NCEP is available here:

http://www.nco.ncep.noaa.gov/pmb/docs/grib2/

and includes code for a GriB1/GriB2 decoder/encoder.

It is recommended, that as a first step, a future version of Manifold be able to import and export NCEP generated GriB1/GriB2 format information products. When this is possible without issue, adding import and export capabilities for GriB format products from other major weather/environmental prediction/monitoring centres, mostly weather forcasting centres (eg UKMO, ECMWF, MeteoFrance, DLR, EUMETSAT etc) could then be addressed.

looking for isobath data

dave223 — Tue, 16 Dec 2008 12:10:51 GMT

Hello, I'm trying to find specific ocean isobaths. The World Seas and Oceans manifold file (in the data folder on the dvd), is close, but doesn't have the specific depth that I need. Is there a place where I can find this online? I have Tom Patterson's CLEANTOPO2, is there an accurate way to process the vectors from that grayscale data?

Many thanks!
