the idea here is to have a xml dataset pulled directly from the database
like http://overcast.net.au/installations/site4/mapxml_4.0.php
we can display the gps coordinates of the sensor mesh

kml PETRO_ACREAGE_RELEASE_AREAS.kml
one layer isolated and uploaded (seems quite easy and works well)
we can overlay map with pipelines leases etc

here’s the complete kml (about 10MB)
doesn’t work might need to pull up as separate layers on a map similar to
http://overcast.net.au/installations/govhack18/govhack18maptest.html
this map: http://overcast.net.au/installations/kmlsets/PETRO_TITLE_EXPL_GRNT.kml
seems 1MB limit?????
