When I toggle to change a folder of about 120 maps (USGS 7.5 min quads) into a collection, a “Loading” message with a whirling icon appear down in in the lower left quadrant of my iPhone screen. Does this mean that the collection is being made from the folder? That is, are the maps being stitched, or linked together?
Thank you for your post. That is correct – because the folder is quite large, converting it to a collection can take a bit of time to process. Please note that a collection does not stitch the maps together into a single map, but rather allows you to move between maps based on movement, scale, etc. This allows you to switch between maps automatically without the need to open the new map you are needing manually.
Please let me know if you have any further questions!
