Drawiing maps of colleges, towns, or anything else in gimp.

Rob, are there any tutorial here for creating isometric grids in inkscape and then importing it gimp and coloring it gimp?

Strictly speaking, that looks to be a trimetric projection, not isometric. (Both are examples of 'axonometric' projections.)

To set up an Axonometric grid, File->Document Properties->Grids, pick Axonometric from the drop down and click New. It defaults to an isometric grid, but you can adjust the angles to produce dimetric/trimetric grids (Roughly speaking, if the angles are 30°, it's Isometric, if something else, but equal, it's Dimetric, if they are unequal, it's Trimetric.)

You can actually do the colouring in Inkscape if you want, but exporting for the GIMP is just a matter of File->Export to Bitmap.
