If I understand correctly those are the relevant parts:
Private organizations, Business Partners, and Developers: 50,000,000 transactions per year. For maps, a transaction is defined as eight tiles. For application scenarios exceeding 50 million transactions per year, additional fees apply. Provide attribution to Esri and its data providers. |
What exactly happens if we exceed 50M?
And this is not clear:
Use with Esri software. If you do not have Esri software, you must purchase an ArcGIS Online subscription. |
We just want to use tiles in Google Map layer (i.e. link to image files on services.arcgisonline.com), do we need to buy somethng for that?
