Global Mapper ... does not look bad
Among so many solutions that come out every day for GIS management, Global Mapper Draws attention with some features that make it attractive apart that has been popularized by being distributed by the USGS as dlgv32 Pro.
Let's take a look:
1. Global Mapper - Connection to data services
This seems most attractive, as they have direct access to imaging services such as TerraServer, DigitalGlobe and other services via WMS
If I'm going to give you the merit it's your interaction with Google Maps, Virtual Earth and NASA World Wind, All data generated since Global Mapper Can be generated so that it can be deployed from those applications; Generating the necessary html for it.
2. Common formats support
Read commonly used formats supported by neighborhoods known as Erdas, MapInfo, ArcGIS, AutoDesk, Bentley, Erdas, Garmin
- Vector format / GIS: DWG, DGN, DXF, SHP, E00, DEM, DXF, KML, PCX,
- Raster format / Elevation: ECW, MrSID, E00, GeoTIFF, Lidar LAS, ArcGRID, Idrisi.
- While supporting formats of platforms not as popularized but of transcendence as being TomTom, Open Street Maps, GML, LandSat fast format, OziExplorer, NOAA and others.
3 Functionality CAD / GIS / GPS
In terms of Image management The option to rectify, reproject and combine / merge different raster formats is attractive. You can also make cuts from the vector to the crop / clip image and auto-contrast effects.
There is a function called True3D, in which images can be modeled based on digital terrain models or their own grids.
I do not have many doubts about their GIS capabilities, but I remain with reservations regarding CAD construction ... until now we still prefer to vectorize in AutocAD or Microstation ... take a look at the ability to create links from any vector object to web pages, files or directories. Also the theming and resymbolization alternatives are very good, I think a single map Could impress : )
It has support for reading GPS data via serial and USB, we understand that it has no problems with gpx formats, but I did not expect it to be able to read OSM TomTom type formats.
Regarding 3D management, digital terrain models can be built based on elevation points or elevations and of course, contour lines in a friendly way. Once surfaces have been built, comparisons can be made, such as cut and fill calculations, as well as operations such as floodplains in basins. In this example we show how easy it is Make a digital model of terrain And their contours, compared to other programs.
3. Developer Options
You have two alternatives for development, one of them is the Global Mapper SDK and the Global mapper DLL License ($ 139 per runtime license). I clarify this, it means that if with that SDK you build a solution to commercialize, you only have to pay $ 139 for the runtime license, the rest is profit.
4. Global Mapper Price
For many it may be surprising that Glogal Mapper worth less than $ 300, depending on the number of licenses it can be found from $ 229 (156.13 EUR). It can be downloaded in a trial version and the upgrade from the 8x to 9x version costs 67 Euros.
The service does not look bad, although it would be necessary to see if they can fulfill that promise that they have there on their page where they assure: "if something does not do our software, let us know and we will try it"
So if you want to try it you can Global Mapper download.
We are GLOBAL MAPPER Distributors for all of Latin America, we translate or apply for Portuguese and Spanish! Therefore, to compare a license, não hesite faça contato!

Hi, Edgar. The accuracy of the contours depends on the information with which they were generated.
It influences, for example the densification of lifting points, the accuracy of the equipment used for this data capture, the cleaning of errors outside the statistical range, the scale of relevance, etc.
There are also contours generated from other sources as existing curves and others from satellite imagery.
Anyway ... It depends on the source of the data.
which is the prism of the level curves ,,, because I compared with a BM taken with differential gps and is not equal
I think Global Mapper can only be bought on the Internet.
Here Is the link
Where is the purchase of the global mapper license in Buenos Aires?
