Although all these things can be done with applications like Manifold, ArcGis just by opening the kml and exporting it to the searched format, the search in Google kml to dxf is incremental. Let's see some features offered by a student at the University of Arizona for free to convert data from Google Earth to formats used by Applications such as AutoCAD, Microstation, ArcView, ArcMap, GPS y Excel
1 Convert from Google Earth to ArcView/ GIS (.shp)
With This application you can choose the data type of the shape file (kml to shp), points, lines or polygons, it also allows you to change the format of the coordinates that bring the kml files (lat / long wgs84) to other formats, such as UTM. The result is the three basic files, the .shp where the figures are, the .dbf where the data is and the .sxf where the spatial index is.
2 Convert from Google Earth to AutoCAD (Kml to dxf)
With This application you can get kml data to dxf format (kml to dxf), which is a standard format that you can open with AutoCAD, Microstation and other CAD platforms. You can choose to migrate the data separately (points, routes, polygons) or also all at once.
3 Convert from Google Earth to Excel (.csv, txt, tab)
This application extract the data from the kml file and extract it (x, y, z coordinates) in .csv format that you can open with excel, it also allows you to choose if the destination is text (.txt) or text separated by spaces (tab) . The same allows you to download separately the points of the routes and the polygons.
4. Convert from Google Earh to GPS (Kml to gpx)
Although This application Can do all the functions of the previous one, it works online and this one has the option of being able to convert to .bln y .gpx which is a very common capture format with GPS. You can also configure the coordinate format, choosing the projection, datum and area.
The best thing about these tools is that they are free, or at least for now. With some you have to fight a bit because they are macros and browsers or Windows configurations can have security levels that do not allow them. Also some may not run with the latest versions of Google Earth.
As it says the creator Of these tools, his passion to spend time and share them has not left him minutes to correct some bugs, to make manuals or to update some that have remained old
To finish throwing flowers to this initiative of Zonums, there are three plus plus for Google Earth:
See el Census of the United States in Google Earth
See The coordinates of a point (lat / lon) In UTM, With its respective zone
See the coordinates of the corners of the image shown in Google Earth (extent), Convenient to not take the points to the chilazo as we did when we saw How to georeference an image of Google Earth.
En This post is detailed the different tools that Zonum has for Engineering, CAD and GIS.
