I've long been a fan of Vasile Cotovanu's polygon masking resultant that allows yous to highlight a detail expanse on Google Maps. Vasile has similar a shot released a sorcerer app that tin move chop-chop practise the GeoJSON, KML, or Google Maps API polygon code needed to practise your ain polygon mask.
Geomask allows yous to but depict to a greater extent than or less an expanse on Google Maps too exactly press a push to generate the polygon to practise this neat masking effect. You aren't fifty-fifty restricted to 1 expanse too yous tin move highlight every bit many areas every bit yous desire on the map.
The tool is actually slow to use. I created a polygon mask to highlight the London Olympic Park too and therefore created a map amongst the mask inward nether ii minutes using Geomask (you tin move run across the resultant inward the screenshot at the altitude of the post).
Using a polygon mask is a real effective agency to highlight a specific expanse on a Google Map. Here are a dyad of Google Maps applications that accept used a similar polygon masking resultant to highlight regions on the map.
Der Bayerischer Wald is a peachy Google Maps take away to hiking routes, accommodation too events inward the Bavarian Forest portion inward Germany.
Ourense en Verde is using the Google Maps API to map the natural beauty of the Ourense portion inward Galicia, Spain.
