![]() So now I am just looking for sat imagery of USA, not worldwide. I tried to find out alternative of google earth for historical imagery but failed. If your ready to spend some money, you can look directly from imagery distributor (Digital Globe, Airbus, etc.). Maybe with Esri, but if they do that, that will probably be spread in different data sets not only one ( ) I don't thing Bing map offer this service. ![]() However, if you looking for sat imagery worldwide, there probably are no providers with this option. In that case, you would need to specify a Time parameter when creating your WebMapServiceImageryProvider (and updating it accordingly). Some services may integrates a temporal parameter. 在 2016年4月7日星期四 will depend on your imagery provider.
