My team is developing a project cost estimation software that contains a GIS component. The performance of our software has been greatly hampered by streaming the Bing aerial WMS. Our imagery needs revolve around small project areas on the US West Coast. It would be idea if we could locally cache imagery tiles on our server. Is this a possibility with the Esri World Imagery layer? What are the costs associated with this request? Do you have suggestions for other imagery services we could look into? Thank you!
