I've have several orthophotos stored in an ECW (Enhanced Compression Wavelet) file format. For most of them the exact acquisition date is referred in the file name - e.g. "Paris_24_12_2011". But for some of them this information is lacking. I'm currently using ArcGIS 10.3.
Is there a way to check when the orthophoto was taken? maybe some metadata? If so, how can I watch this data?
- I've tried to look it up and found this page of ECW file specification including metadata for GDAL use. I'm not familiar with GDAL so I left it aside for the moment.
- I've downloaded erdas er viewer 2014, thought it might give me some metadata access. It didn't.
Is there any simple, free-to-use way that can help me find the date of the orthophoto?
