[GRASSLIST:4557] Re: [winGRASS] A million and a half questions.

[Mike Thomas]

Hi Dave.

Welcome to the world of GIS and Grass.  It can only get better for you from
here although the road may be painful at times!

The wingrass mailing list probably isn't the best place to ask most of these
questions, as it is relatively small and specialised.  Accordingly I have
cc'ed your email to the main Grass list which has many more subscribers and
where you may have a better chance of getting the kind of information you
need.

It seems to me that you particularly need to find a surveyor or cartographer
using Grass in the United States.

The Windows Grass release is experimental, but is never-the-less
sufficiently solid to be used by at least one professional geographer that I
am aware of.

Cheers

Mike Thomas.

starting to research GIS -- so naturally, I've got a million and a half
questions.

states with a public land survey system (Townships and Sections) that might
give me tips.

ruled out the possibility of building a Linux box for the office network,
which is currently running Win2k.)

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?

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?
