I have a layer of manually set points in qgis that have the following attributes at the moment :
id, lat, long
Additionally, I have a number of different overlapping raster images (sattelite data) that are all tagged with a date using the TIFFTAG_DATETIME in the raster's metadata.
What I would like to do is to form an additional attribute for the point layer that is called dates:
dates = ["2015-01-01", "2015-12-01]
The list of dates should contain all the dates of satellite imagery that contain the particular point.
Any ideas how to do this in qgis. If needed I can also use different methods of tagging the GeoTiff file. Or maybe even create polygons that have the date as attributes. But the code that is creating and tagging the GeoTiff files runs outside of qgis.
