My primary software app is Seismic Micro Technology’s Kingdom Suite, which you’re not likely to use unless you’re in my corner of the mapping world.
But possibly of more general interest, I use Golden Software’s Surfer for surface mapping, pretty 3D pictures and, significantly, data manipulation. While a powerful program, it takes me back to DOS days because you cannot directly edit a contour map - you have to go all the way back to the input data set to make changes. And then run through several steps to see if you got to where you’re going. It is my digitizing package.
DesignCAD is my other true global coordinates data manipulator - a hell of a lot cheaper than AutoCad, and it lets me manipulate *.dxf and *.dwg files.
For final output that needs additions for illustrative purposes, CorelDRAW beats the heck out of CAD, but it cannot handle true global coordinates. But it easily outdistances the CAD programs for illustrative capabilities and ease of use. And, I’ve found that with a little practice, I can reacquire true global cordinates in Surfer.
Another that y’all might find useful is Seissoft’s shareware Coordinate Conversion. Its help files will teach you most of what you’ll ever need to know about global projections. John Banta deserves a kudo for that one.
And, of course, you’ve got all the wonderful cartographic, hydrographic, cultural and digital elevation data downloadable from the USGS EROS Data Center. You need to get comfy with things like sdts2dxf.exe to use the data, but my word(!), there is a gold mine there.
I’m just not up to plugging in all the links, as I usually do. If any of you want 'em, let me know in this thread; I can probabaly supply a link to any of the above.
All of that being said, let me reiterate that I still use a lot of pencils, colored and otherwise.
