M_GMT a Graphical User Interface to GMT

Analpha-Beta 0.5 This version didn't change much in M_GMT (only a couple of bug corrections), but marks the appearence of the new program: Mirone. Due to that, the M_GMT image viewer was replaced by a "Mirone Light", for the ancient functionalities were more than replaced by the new program. The source code as well as the Windows pre-compiled file includes both the M_GMT and Mirone programs.

 

Analpha-Beta 0.3 version allows reading of: GeoTIFF DEM, DTED, USGS DEM, USGS SDTS DEM, Gtopo30, SRTM DEM, Arc/Info ascii/binary grids, ENVI, ERDAS .img, GeoTIFF, GXF and exporting to GMT grdfiles or common image formats (.jpg, .tif, .png, .bmp .ras, etc..) via an image tool window.

Warning 1: this operations are performed with the imported grid on computer's memory that at a certain point have to be in double. So, if you try to read a Gtopo30 tile you better have 512 Mb of ram or prepare for wild swapping.

Warning 2: External grids are converted to GMT grids maintaining their original projection.

Well, given that GMT is in fact a collection of about 60 different programs and that the time (and knowledge) required to build a GUI for each module is very long, M_GMT currently contains only a sub-set of the total package. Click HERE to see the list of the currently GUIized programs.

M_GMT is written in Matlab but a stand-alone version to run under Windows is also provided. The other possibility is to run it from Matlab. In this case, both Windows and Unix/Linux OS are supported, but you have to have Matlab version 6.5 installed in your computer (it doesn't run on previous Matlab versions). 

In principle, it's also possible to build a stand-alone version that runs under Unix/Linux, but I haven't done so. If someone with access to Matlab 6.5 with the compiler toolbox wants to take the job I'll be glad to hear it and host the corresponding binaries.

If you don't know it, there are currently two other graphical interfaces to GMT. One, Win4gmt, runs only under windows but, in my opinion, it is of limited usefulness because it doesn't do any error checking, and errors in the GMT parameters is the thing we do more. The other one, iGMT, is unix oriented but can be persuaded to work under windows/cygwin with a relatively low amount of pain. I didn't tried seriously enough to be able to give an opinion. It contains, however, an excellent collection of links to free data. M_GMT is quite different from those two.

BUGS. Very likely there are still many. Tell me about it.
