Mike, You can load JPG files using the normal File->Open menu command or by dragging the JPG file onto an open session of Global Mapper. Direct load of BMP...
I saw the earlier post about this subject, but was not a member at that time. The discussion automatically deletes the example file, so I am afraid that I do...
Load some DEM and line and point data into GM, then export it as a generic ASCII file, being sure to first make some changes that will have the attributes that...
Can GM generate DEMs from vector contours? How abount if 3D coordinates were extracted from contour vertices? If not, are there any recommended apps that...
Alan, You can generate DEMs from vector contours in Global Mapper, it just takes a few steps. This should be improved in the next release or two so that you...
Thanks Mike. For this to work, do the contours have to be positioned in 3D space at their proper elevation or can they simply have an attribute with the...
Alan, Either way will work. If there contours aren't already in 3D space somehow (like there were generated using the Contour Generator), if there is an...
What if the elevation values are stored in an attribute with a strange name. How does GM know to pick up on this value? -Alan ... be ... either ... positioned...
Alan, Global Mapper wouldn't have any way to know that the strangely named value was elevation. What you could do is load that file in from whatever format...
I load the DEM files I want... 6 degrees square. I then load "citiesx020.tar.gz" and that puts every town and city in the US on the screen, in the correct...
What you first need to do is make sure that your view/export projection is set to Geographic/Arc Degrees on the Projection tab of the Configuration dialog....
Hi Mike Is there any progress/update regarding the polylines to polygons convertion option? After reading the contour to DEM conversion method, this would be...
Alberto, The polyline to area conversion is not done yet, but it is still a high priority item on our wish list. Hopefully it will be done in a month or so. ...
Hi all; I've written up a brief survey of fixes for the "holes" problem that has been discussed on the Yahoo! Terragen list recently. It's available here: ...
Tim, Did you ever see this one? I saw it in mid to late December... and it was posted re VTBuilder, if memory serves. It may impact your survey ... ...
Great product! I was trying to get a vector-line for the coast in a set of DEMs I have, so I thought to use the 'Generate Contour' function. However, the...

I think I found a hack: 1) Adjust elevations to Scale:1, Offset:-1 for my DEM. (Being careful with lower valid-limit to avoid truncation.) 2) Draw Contours...

That's actually a pretty clever way. I was going to suggest clamping the min/max elevations on the Adjust Elevations dialog to -1 to 0 meters and specifying a...
I have a vector file without z coordinate, and a DEM and contour lines in 3D (x,y,z) of the same area. Is there any way in GM to save the vector data with the...
Luis, If you just load the DEM data and the vector files, then specify to create 3D features when you export to your vector format of choice, the elevation ...
And there's a LOT of free 10 meter data out there now. Go to http://seamless.usgs.gov/. You can download a lot for free. Frank ... From: "Global Mapper...
Thank you Frank, the address is great. By the way, do you know where can I find recent images of South America (Ecuador) for free ?? Luis ... De: Frank Looper ...
Try this site below, it's great for georeferenced Landsat7 images. Some images are as recent as 4 years, average about 15 years though, but hey, it's free 30m...
Does nayone know what parameter GM is looking for, in a vector file, in order to identify lines (road, river, etc.) and symbols (bridge, etc.) so that they are...
