Hello, When using Google Collect, I always tried to link my plot to high-res imagery from Bing Maps. But the capturing date on the Bing Map image may not be correct. So i want to make sure this date is the date when the image was captured or the date when the image is updated on the website. This date is critical for the application. Sorry i am not allowed to upload the screenshot. Otherwise i can show you the problem. Thanks, Jinkai |

More information on this. When using the Bing Map API to get the metadata, i found the following tags related to the capturing date: VintageStart and VintageEnd. It is better to stamp the date range instead of the VintageEnd time Below is one example of the metadata i got. <response xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.microsoft.com/search/local/ws/rest/v1"> <copyright> Copyright © 2017 Microsoft and its suppliers.

Hi Jinkai, The capture date from Bing Maps is not really well explained. The VintageStart and VintageEnd dates refer to the start and the end dates of the imagery stitched together by Bing Maps in order to produce the map tiles. If you want to see both dates you will need to replace the file C:\OpenForis\CollectEarth\resources\collectBing.fmt with this one : LINK Hope that clarifies. We will go back to showing both dates in the default Collect Earth installer. |
