I was thrilled to learn that the ArcGIS Storymaps team has added support for custom basemaps in Guided Tour maps.
While this feature is nice to see, it would be even more useful for me and my client if custom basemaps were enabled for Express Maps as well.
In my specific use case, I need to build a map that lets its users learn about 20-30 infrastructure sites that are part of a much larger infrastructure network (~500 sites). While I did briefly consider creating this as a Guided Tour, my client has explicitly requested that the users be able to choose which sites they want to learn about and that the map should not impose any sequence in which those sites are presented. Ideally, I would like to create an Express Map with the whole network shown on the basemap, and the important sites shown as individual points (created manually in the Express Map editor) with content-rich popups.
Are you planning to add the custom basemaps feature to Express Maps any time in the next 4-6 weeks?
Thanks Owen Evans and the rest of the Storymaps team for the great product!
