I am doing a quick R&D on geospatial data workflow inside Terragen and would welcome some tips/links to resources on what is the fastest way to acquire data. I have skimmed several tutorials on that for TGN, played with GIS websites, etc... I am a total newbie in that area, so sorry if my questions will seem naive. My questions are these:

1. MULTIPLE DEMS (selected region)
a) What is the most fuss-free approach to getting multiple seamless DEMs inside TGN ( is unavailable).
b) I have played with I can download chosen heightfield data "products" for the rectangle I select. What about color data matching those heightfields? (same cropping of files)?
c) I have seen Global Mapper used for certain operations, like pulling data or mapping conversions. The best free alternative seems to be QGIS. Or am I wrong here?

a) should I pull Earth imagery from NASA or is there a better resource?
b) what is the most detailed resource for this task (free) ?

Thank you in advance!

Various USGS Sources:



Land Info New Zealand:

SRTM Data:

ALOS Global Digital Surface Model "ALOS World 3D - 30m (AW3D30)"


Space Data: has really low res terrains imo, but regardless, offer a extremely straight forward process to concept stuff. The elevation data in WA doesn't seem to strip trees either, so in logging areas, creating terraced grounds that don't exist. Lol
