I want to geotag photos to an existing shapefile but I am not sure how. I have a point shapefile of memorial plaques, and I have a folder of pictures of all of these plaques. The photos have no spatial information as I took them with a small pocket camera. I tried using the "geotagged photos to point" tool, but my pictures don't show up because they don't have any spatial reference and it also generates a new shapefile, which I don't want. I want to tag them to a pre existing shapefile as this shapefile has all of the attribute information stored in it. Any ideas of suggestions would be helpful.
