Having experimented a bit more with the various presentation features of GM, I have a possible approach to the hand-editing of hydrographic layers on the...
When i create elevation grid from vector data i get some unwanted results. This is some spikes at sea level. I am not able to figure out what is wrong but the...
2 queries, the first for Mike, the second for anyone who can answer. 1. I own the extraordinarily expensive 'Digital Chart of the World' 'for use with ESRI...
The creation of elevation grids uses triangulation to build the grid. If there are no data points in your sea level area to grab onto, then you'll get large...
Nik, I believe that the 'Digital Chart of the World' is actually an older version of the VMAP0 database which is in the VPF format which Global Mapper can read...
Scott, There is not a way to do that in GM v5.10. That functionality was added in GM v6.00 and is on the General tab of the Configuration dialog in all v6.xx ...
Mike, I have version 5.10 and it has the option to change the Grid Spacing on the General tab in the Configuration dialog. It's in arc degrees. '0.1' gives...
Dan, What you have is actually a post v5.10 release of Global Mapper made prior to the v6.00 release that included some of the v6.00 features. No publicly ...
The problem is seen when the shoreline is on the same place as a countour line or the shore line is on the "wrong" side of the contour lines. I could edit the...
It seems like you would only need to edit the shoreline in the couple of places where you have trouble. All that you need to do is enable vertex display on the...
I am using the free 500m DTM data from Computa Maps. For some reason Global Mapper plots the Souther hemisphere data in the northern hemisphere? Is this a...
In order to solve the problems with sea areas or no data areas in elevation grids, I suggest the possibility to create an edition tool in GM to define a...
That's exactly what i need to solve my problem with the sea areas. This tool will also solve my problem with lakes that i need to "flatten". Hope it is...
Mike, thx for the advice. I'll check those sites over the w/e. Don't think it has those filetypes but cannot check till tomorrow. One minor suggestion. When...
How can you control the quality of the finished texture. I have produced the same 3d model with the data and corrected image on two computers with very...
The quality of the texture depends on the number of pixels in the original display. To get the best quality, I'd suggest maximizing the Global Mapper display...
Thanks for the suggestions guys, they sound good. I do plan on adding elevation grid editing functions in a future release, so I'll keep this suggestion in...
Before beginning the "Open Generic Ascii Text Files" Quite often I will have a set of 10 seperate XYZ data sets (each in excess of 1,000,000 points) and...
In Arc 9.0 toolbox there is an "Ascii to raster" utility for importing the grd file created in Global Mapper but you have to change the extension of the file...
The problem is that the format of the DTM files from Computa Maps has a projection file that specifies the UTM zone that the data is in, but not whether or not...
Mike, What I would suggest is creating a .prj file with the same base name as the XYZ file so that you aren't even prompted for the projection. You can create ...
Hello, I just started using GM v 6.03 When printing or viewing to scale I do not get the expected result. I need to view/print at 1:12741813 scale. This would...
Hi, I'm playing with the 3d Viewer at the moment and it is pretty cool. I understand that you are rebuilding the viewer. Can I make a feature request? I really...
Conor, Wouldn't you want to use a scale value of 1:40005040 which would make one meter of paper equivalent to the circumference of the earth? The value that ...
Ian, You can already export loaded terrain data to a VRML file from the File->Export Raster and Elevation menu. Perhaps that will work for you? Mike Global...
Mike, The grid size of output files in Gravsoft format dose not match exactly with user defined size. Please check it. Is it possible GM accept import of this...
I notice that a digital elevation model, when contoured, does not contain the highest elvation contour. For example, if the highest grades are 110.5, and...
