I'm trying to generate rows for paddock for a farmer GIS application.

I manage to reach the point where I have the following variables:

====

Drawing allpadocks = ....;

Drawing allbaserow = ....;

Geom paddock = ....;

Geom baserow = ....;

====

Now, to make it simple, I need to produce a geometry which will cover the paddock with line parralel to the baserow, 1 meter apart.

Where I'm stuck now is, while the paddock could be approximate to an euclidan geometry (i.e. in a plane), I don't know how much of a given unit is one meter, I'm not sure that the X and Y coordinate system is cartesian (i.e. the X and Y line are perpendicular).

Any clue how should I go from there?
