Although all these things can be done with applications like Manifold, ArcGis Just by opening the kml and exporting it to the desired format, the Google search for kml to dxf is incremental. Let's see some functionalities that a student at the University of Arizona offers 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 coordinate format of 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 (km to dxf)
With This application kml data can be obtained in 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 extracts the data from the kml file and extracts 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) . It also allows you to download the points of the routes and the polygons separately.
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 GPS capture format. You can also configure the coordinate format, choosing the projection, datum and zone.
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 Windows browsers or settings may 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.
