I am trying to add OS TOPO data as a background map in a collector app. We have connected the Ordinance Survey TOPO data from OS On demand service via a WMS, and it works fine when logged in on the web portal.
The OS On Demand WMS has been successfully added to a map as a basemap
But when you view the basemap on the phone collector app the projection is incorrect, instead of displaying the basemap in a British National Grid (BNG) projection, as it is displayed within the online map, the basemap is displayed with a different projection which shows the map to be stretched.
The issue seems to be that OnDemand supports both British National Grid and WGS84 projections. As far as I am aware, you are not able to specify a projection for our map. The map uses the projection from your “Basemap Layer”.
How do we get the collector app to default to BNG not WGS84?
