I've made checker that counts founds or number of different cache types in given polygon or list of polygons.The polygon(s) is defined in config or in json database. You can create the polygon with google maps and extract it from the kml file.
The founds can be limited by allowed or disallowed types. The output can be personalized in config, like "logTitle": "I have found __nrfounds__ caches on peninsula of Bibione:"
the checker is here:
