My question is: how can I check the date (or last update date) for a terrain elevation data on a specific location? Also can I determine this for the satellite photo?
While browsing my application I have noticed that some areas are outdated, and would be nice to mitigate this issue. A follow up question would be how can I add more data or other sources of information regarding terrain elevation in order to complement this gap of outdated data?
Any insight would be highly appreciated!
