I am a software developer who has been producing maps that display GIS data using:
1. Leaflet map API
2. ESRI Leaflet plugin
Acting as a volunteer, I produce maps related to disasters (particularly wildland fires) and post them on social media.
Currently I have a free ESRI developer account. However, I have been informed by an ESRI rep that this type of account is not supposed to display tile layers that ESRI owns which are part of ArcGIS Online.
For example, my map has been displaying this ESRI tile layer which consists of scans of the old paper USGS topo maps.
I have 2 questions:
1. If I buy the ArcGIS Online Individual license will that entitled me to produce maps that display tile layers that ESRI owns which are part of ArcGIS Online?
2. Does an ArcGIS Online Individual license have a rate limit? For example, the free developer account has a limit of 1,000,000 million basemap tiles per month. The fire map I produce is popular and in March my developer account exceeded that limit by about 10%.
