Mike, I finally got around to trying to write a plugin for my *.bgd format import. The file seems to load okay, but I see no display of the map. The metadata...
I need to clip lidar data from an entire county by Township. Is there a means within GM to accomplish this task - automatically or semi-auto? Thanks....
If you have the township boundaries as polygons, you can load the Lidar data and the township data in Global Mapper, then select all of the township polygons...
Excellent. Thanks Mike ... Lidar data ... township ... Use the ... selected ... boundary. ... [mailto:global_mapper@yahoogroups.com] ... there ... auto?...
When making a map from many xyz entries, data thinning is often nessesary (or advised). Can this be done in Global Mapper, and if so, how is it done? Regards...
Hi Can I find out what the transform settings are for a particular inbuilt datum? Specifically I am looking for the dx, dy, dz for Merchich (Morocco) as I am...
"The National Imagery and Mapping Agency (NIMA) lists the shift from “MERCHICH Datum” (sic) to WGS 84 Datum as: DX = +31 meters ±5 m, DY =+146 meters ±3...
Nick, See http://globalmapper.com/helpv10/datum_list.htm for a list of the transformation parameters of all datums. Let me know if I can be of further...
You can simplify features to remove vertices that don't contribute much to the shape by exporting to a Global Mapper Package file and using the Simplification...
Mike Thanks. However, the one I am interested in -Merchich - specifies the ellipsoid used as Clarke 1880 (which is fine). Then I checked the ellipsoid.csv file...
I think I wasn't precise. I meant when making a DEM or Bathymetric map. Often one have a series of elevation data for the same pixel (apart from invalid data),...
Nick, The Merchich datum is based on the base Clarke 1880 ellipsoid, which has a semi-major axis of 6378249.145 and a semi-minor axis of 6356514.86955. Ignore...
Ah, I see now. Currently if you have multiple elevation values at the same point location in your input data for generating an elevation grid, Global Mapper...
Hi Mike Thanks for that. I think I see where I may be getting the error the Moroccan state cartography department have a major of 6378249.20 and minor...
Nick, That is a very small difference, I would expect any differences based on that to be well under a meter, but there would be some small difference. Thanks,...
Mike, I loaded some hundred ecw file which I want to export as one file. But my ecw export stops with the error report: Error 53 "Could not read line from...
Greina, Based on where the error is coming from I think it is not referring to one of your input ECW files but instead one of the temporary image files that ...
I am running a script in which I am trying to export some vector data as KMZ. The posted GM script reference page says to use parameter "TYPE=KML" for both...
Jon, Are you exporting vector or raster data? Just specifying a file with a .kmz extension should be all that you need to do. Thanks, Mike Global Mapper...
Hi Mike, I checked the reference and searched the forum but couldn't determine whether there is a keyboard shortcut for "Edit Feature" (in Digitizer)? ...
It is vector data only consisting of area, line and point types. I am specifying an exported filename with a .kmz extension, but the resulting file is not...
Ah, I've discovered the source of the issue by fiddling around with things. It appears that it is case sensitive. I was specifying a file name with a ".kmz"...
David, Actually if you double-click on an item it should automatically open the edit dialog for that feature. Let me know if I can be of further assistance. ...
