--- Start of Idrisi List message
Hello out there
I'm currently digitizing (using Cartalinx) contours of
my study area from an orthophoto which is in Gauss Conform
Projection. This is not one of the projections listed as
supported by Cartalinx. However I gather that some
projections are identical to other more common ones e.g.
one of the Gauss is the same as Mercator. So - a few
questions for anyone out there who can answer them please:
1. Does anyone know if Gauss Conform is the same as any
other projections?
2. The area I am digitising covers no more than a degree
but is on a 1:10,000 scale - does the projection even
impact at this scale?
3. I am currently using a PLANE and KM setting for
digitising these contours but ultimately want to
integrate data from GPS and satellite images. My GPS
operates with LAT/LONG and WDGS 84. Am I creating
problems for the future or will I be able to transform
this stuff in IDRISI?
4. Can I download tracklogs directly from a Garmin GPS III
to IDRISI (NMEA format)? I'm currently trying to do it
using FUGAWI software and its driving me mad by not
working when its supposed to be fully compatible.
Many thanks for reading - any advice in Joe Bloggs language
please - summarised answers will be posted out.
Cheers.
Lorna
