To create contour lines from Google Earth on AutoCAD, first you have to download these software:
TCX CONVERTER: is the critical piece of software you’ve been missing.
With TCX Converter you don’t have any more worries about incompatibilities between files for different outdoor GPS devices and mapping software.
With TCX Converter you can:
-Import TCX, GPX, FITLOG, KML, TRK (and more to come...) files
-Join multiple GPX files into one big course
-Import directly from Garmin GPS via Garmin Communicator Plugin or GPSBabel plugin
-Add or remove Waypoints with a simple mouse click
-Truncate the track at any point you like
-Update altitude data (internet connection needed)
-Change average speed of the course
-Import/Export Waypoints with smart repositioning function
QUIKGRID: is a program which will read in a set of scattered data points (x, y, z) which represents a surface. The program will generate a grid from this data and then display the surface as a contour map, or as a 3d representation. The left mouse button may be used to zoom in and pan about the display. The right mouse button may be used to display information about the generated grid coordinates and data points.
