Esri has released a free app for iOS that interfaces with ArcGIS Online, allowing Esri users to view GIS content from ArcGIS Online to assist with the drone flight planning. (This was originally developed by Esri business partner 3DR)
The Site Scan - Limited Edition app (formerly called "Site Scan - Esri Edition") provides mission planning and flight control for a number of leading drones to optimize drone collections for use in Drone2Map or Ortho Mapping in ArcGIS Pro. This release is compatible with the DJI Phantom 4 Pro, DJI M200, DJI M210, DJI Inspire 2, DJI Mavic Pro, or Yuneec H520-G, as well as the 3DR Solo.
The Site Scan - Limited Edition app allows users to take advantage of substantial amounts of publicly accessible data, as well as custom data layers from the user’s ArcGIS Online account, as base and reference data for mission planning.
Site Scan - Limited Editionis free to everyone with an ArcGIS Online account. The app is available on iTunes at http://esriurl.com/SSEE, and will be available soon via ArcGIS Apps.
