Hi,

I am using the translators PhotoCoordinateExtractor to VertexCreator and then writing to a shapefile in order to get points from photos. The problem is that the shapefiles then don't have a spatial reference.

Is there any way of getting what the spatial reference / projected coordinate system is from the EXIF information or any FME feature attribute?

Or should I just assume that its WGS84?

Here are the attributes I know exist, but I dont think any of them can answer my question:

Thanks for any advice!

The EXIF coordinates are always stored in lat/lon, degrees minutes and seconds, if I recall correctly the PhotoCoordinateExtractor converts that to decimal degrees and thus it's LL84
