Adding custom WMS service 3

Starting from version 1.3.5 – MapPad Pro and 3.2.5 – MapPad Demo (available on Google Play from 31st of Jan 2014)  is now possible to add custom WMS service (version 1.1.1 or 1.3.0) as a Google Maps overlay, it’s a very useful option requested few weeks ago by one of our customers.

The only factor determining if WMS can be displayed properly within MapPad application is that it supports Web Mercator projection (ESPG:3857) which is being used by Google Maps.

The easy way to check that is examine the capability file of the services, example can be seen here – you need to check if WMS supports EPSG:3857, CRS:84 or EPSG:4326 if so there  is great chance that the service will be displayed in MapPad as expected.
