Cross Section Generator for Google Earth

Generate emerging Google Earth cross-section using two cross-section textures (png, jpeg) with optional ground overlay map

Try it out!



  • Step 1: Choosing your location in the Teleport field.
    center on your location type lat, lon or a zip code or an address and click the Teleport button

    • e.g:
    • 36.8857° N, 76.2599° W
    • 36.8857 N, 76.2599 W
    • 36.8857, -76.2599
    • norfolk
    • 23508
  • Step 2: Prepare two images for the sides of your cross-section A and B (not larger than 2 MB each) and ground overlay image to help you position your cross section precisely.
    • Choose these files or enter their URLs and press “Upload”
    • After few seconds (depending on your connection speed) you will see your cross-section
    • If not satisfied, upload new images
  • Step 3: Position your ground overlay to match by:
    • Dragging pins A and B
    • Entering explicit coordinates of latitude longitude box N S E W in input field
    • Enter angle of rotation if necessary.
    • Change transparency of the overlay for visual matching
  • Step 4: Position your cross-section by dragging the controls or entering data
    • Drag thePulpit rockto change the position of the cross-section
    • Drag thePulpit rockto change strike or drag it while Shift key is pressedto change length of your cross-section
    • Horizontal slider will change the plunge of your cross section
    • Slider on the left will change tilt of your cross section
    • Two sliders on the right will change elevation and stretch of the cross-section
  • Step 4:
    • Click the ‘Generate KMZ’ button


By importing a CSV file from the geo field book app we are visualizing field data in Google Earth. We can:

  1. Import a CSV file with geolocation of the symbol along with the type, dip, strike, and so on.
  2. Edit properties of each symbol.
  3. Customize annotation.
  4. Export as KMZ or CSV file.

Moving and Rotating Google Earth Elements

We are using the web based Google Earth to translate and rotate polygons and poly lines for plate reconstruction. After uploading a kml file by either dragging and dropping it to the designated area or selecting it from local drive you can do several things:


  1. Select individual features from the list of features to apply operations on
  2. Perform a translation by dragging and dropping a destination pin, or by typing in heading and distance of the translation.
  3. Do a similar procedure for rotation, define an Euler pole and an angle of rotation.
  4. Simplify features by predefined height of the triangle to be simplified.
  5. Edit the shape of individual features.
  6. Change the color of individual features.
  7. Create intermediate steps for rotation or translation.
  8. Create a time span, the sort of animation that can be played in the Google Earth app.
  9. Also you can reexport this as a kml file.
  10. Finally, there is always a convenient undo button present.
