[winGRASS] A million and a half questions.

[Dave Graham]

Hello everyone; I'm new to the list, so let me start with an introduction:

The name's Dave Graham.  I'm an instrumentman for a small civil engineering/land surveying company in Bloomington Indiana, and I'm just starting to research GIS -- so naturally, I've got a million and a half questions.

For starters, I'm wondering if there are any other surveyors on this list using GRASS or WinGRASS who might give me testimonials -- or surveyors in states with a public land survey system (Townships and Sections) that might give me tips.

I'm fairly familiar with Linux/Unix -- though my boss and coworkers aren't, which makes WinGRASS a reasonable compromise.  (Though I haven't ruled out the possibility of building a Linux box for the office network, which is currently running Win2k.)


Regardless, many of my questions could probably be answered by anyone on this list, so here's an example:

I'm considering creating a GIS in which each Section is a plane; land surveys in that Section will accordingly have x,y coordinates within that plane.  This would, of course, create a gigantic soccer-ball of Section-Planes.  Say then, that I aquired a huge area of data that spanned multiple sections in a different projection, like UTM or State Plane -- am I going to be able to use the two together without alot of hairy conversions?

Also, how would something like this be set up in GRASS?  Would I have to create a separate location for each Section, giving it an x,y projection -- or would I be able to get by making a location for each Township, with each Section as a mapset?


The questions only get worse from here; any help would be greatly appreciated.
