KML-GRID: Creates a point, line or filled polygon grid in KML. Set the desired parameters:
Clicking on “Data Fill Example” enters sample data into the boxes. For Grid Origin, it’s decimal latitude/longitude. For Increment/Decrement, it’s currently also decimal degrees, as the “Length Units” drop-down at top is currently limited to those units (wouldn’t surprise me if additional unit options were added soon). Click on “Create GRID”, and a view of the grid is shown in Google Maps (lines in this case):
Click on the “Download KML File” button, and the KML code will appear in your browser; either choose “Save As” from the File menu, or copy and paste it into a text editor and save it as a KML file there. Open it in Google Earth, and there’s your grid:
A useful complement to GE-Path for creating KML grids.
KML – Area & Length: I’ve covered some other utilities that will calculate path lengths from KML code, filling in a gap in Google Earth. This new utility calculates not just path lengths, but areas as well. Paste the KML code into the text box:
For KML files that have both paths and polygons, you can calculate just the path lengths, just the areas, or both; set the units and the delimiters at top. When you click on “Process data”, you’ll get back a text window with the IDs and lengths/areas of the features in the KML file, separated on each line by the chosen delimiter. e.g. for the grid file above:
