I am looking for the best way to produce a layer of a georectified site plan or image for use within Collector. Does anyone have any recommendations for producing a high resolution layer?
Are you looking to view this site plan within Collector as a referenced layer (non editable) or will this feature be edited?
If you are looking for this site plan/ image to be a reference layer you are able to create a tiled map service (or vector tile service based on your needs) and configure it for offline use so that it can be appear in your web map along with your editable data.
