Hello, I cannot get us elevation data. I added the alternative WMS sites for both the USGS and SRTM alternatives to no avail. Are there any ideas about how to...

Fred, Apparently the JPL/NASA server providing the NED and SRTM data is requiring some maintenance that should be done soon. They are also planning on ...
Hi I have some bathymetry data showing the uk coastline in *.adf format. It loads into GM fine and shows up as having height data but when I export it as an...
Jake, That is strange, the ADF file elevations should export just like any others. What projection do you have setup on the Projection tab of the Configuration...
Hi All, I have a quick, hopefully easy question. When creating a custom shader palette, the default elevation units are always meters. If you select feet, it...
Tofer, Actually the latest v9 build already allows editing elevation values in whatever elevation units that you have selected. I have placed a new build of...
Hey Mike, I downloaded and replaced the .exe and now my last 2 .GWM files have no projection and the DEM and topos (tiffs) I had loaded are gone. Any thoughts...
Tofer, That is strange. What kind of error are you getting about the projection and what projection are you using? Thanks, Mike Global Mapper Support ...
When I last saved it was in UTM 13 NAD27 feet and I have 8 DEM tiffs and about 40 topos. When I open in now, it goes through an import screen, asks for all the...
I sort of had a similar thing. An old workspace loaded, but asked for projection of a geotiff. Struck me as odd at time, but just went on and saved the...
Virgil, I took a look and discovered that the last few builds have been missing a new required file for decoding GeoTIFF projections. I have placed a new build...
Mike, There seems to be an error when projecting outside 180 degrees (into the corners). I am uploading 9.03 VDG error.jpg I am using V9.03, Apr 30. Conor...
Conor, What exactly is the error? The grid lines seem to change some direction. I'm really not sure what the math for the projection does when you leave the...
Mike, I'm not completely certain what the correct result should be, however i do have some published VdG political maps that extend to the corners. In those...
Conor, I'll try and decipher the projection algorithm to see if I can determine what is happening, but I can't promise anything as it's not my code. Thanks, ...
OK, Mike Conor ... From: Global Mapper Support <global_mapper@...> To: global_mapper@yahoogroups.com Sent: Saturday, July 12, 2008 2:52:24 PM Subject:...
Conor, I've taken a look at the math for the Van Der Grinten projection but can't see any obvious reason why there would be an inflection point as you cross ...
Mike, I try to export the result of a View Shed Analysis to a Simple ASCII- xyz-File with the Z-Value beeing the Elevation of the Elevation-Modell (which I did...
Mike, I examined the code but realistically I cannot decipher it. BTW: Apparently GDAL in FWTools has the exact same issue though it looks like your code is...
Conor, I'm glad that you were able to find a solution. If both GCTPC (what Global Mapper uses) and the different projection code in PROJ4 have the same ...
Peter, The view shed layer does not contain any elevation data. It is a raster image layer that will also have a single point feature for the transmitter and...
Mike, in fact I dit mean the polygons in the view shed layer (Using "Generate Area Features in Covered Areas). When I export them (export vector data to get a...
Peter, Ah, I see what you mean. I have updated the view shed coverage areas to no longer get elevations from the TRANSMITTER_HEIGHT attribute. I have placed a ...
Dear Mike If I have central coordinates of an area / point and I want to make a square (say 11 Km x 11 Km) around that specific point to place an order to...
Saif, If you have nothing else loaded, I would suggest using the Digitizer Tool and creating a range ring of the specified radius, then open the Control ...
I'm having an issues exporting what started as .dem data to another vector (grid format.) I have the data loaded and is looks fine. The rough extents are in...
Tofer, Make sure that you are entering negative values for the longitudes to keep them in the Western hemisphere. If you enter positive values that will look ...
I am, I know that GM likes them like that...I actually tried both ways to make sure... I found a solution and that was to export x,y,z triplets. That was the...
