I have a survey set up in Survey123 and need to collect a polygon (Geoshape question) using a webmap as a basemap. The webmap I would like to use is in British National Grid. I have been informed that Survey 123 does not support maps other than those in Web Mercator. Would using Field Maps (or Collector) be an option? So, basically what I am asking is...For the geoshape question can I link to Fieldmaps (or Collector or QuickCapture) with a webmap in BNG? Or do they not support this projection either?
Many thanks for your help.
Cheryl, Collector and Field Maps support British National Grid .
