Generating Cache Density Plots
About Density Plots
Cache Density plots are nothing more than a specialized google earth file that includes horizontal colored planes representing how many caches are undereath each square. Red squares have less caches underneath, purple have more.

Command Line Instructions
geoqo -s set:import:myPocketQuery -e out.kml
Creating a cache density plot will let you see where the most dense caches of an area are. To do this, you need to export data to a "kml" google earth file. The density plot will be included with it.
You can either create a kml export from the command line using arbitrary search terms as shown above, or you can use the GUI:
You will then need to specify that you want to export data to a file, so click the checkbox for doing so:
Then select the pocket query (for example) name you want to export in a density plot, and change the output format to "Google Earth (KML)" and the file name to a .kml ending of your choice.
The next screen will let you set parameters that affect the .kml file. There are a lot, so I suggest starting with the default and working from there.
Then, launch google earth and open the resulting file. The "red" areas will be the areas with the least number of caches in them, and purple will have the most.

- Saved Specifications: Using saved specification strings
- Differences since last import: find all the differences in a pocket-query (or whatever) since your last import
