Photomapping In JOSM

This guide is based on JOSM version 3196.

Open the GPX file that you which to correlate to the photos by going to File-->Open and browsing and then opening the GPX file. The file should then be listed in the "Layers" box, top right hand of screen. Next right click on the GPX file and select "Import Images". Open all the images files you want to correlate to a GPX trace by going to File-->Open and browse to the images that are associated with your GPX file. You can select all image files, by highlighting one file (any file) followed by the "Ctrl + A" shortcut.

Next you will see a dialogue box at the top of which is a drop-down menu called "GPX track:" from the drop down menu select the .gpx file that you wish to correlate to the images (should be the only one loaded at this point).

Next you need to get JOSM to work out the time-difference between the points in the GPX trace and the photographs. To do this click "Use photo of an accurate clock, e.g. GPS receiver display". This will bring up a new dialog that has a list on the left of the photos you originally loaded. Choose whichever image is the picture of your GPS receiver and fill in the box next to "GPS time (read from the above photo):". Nb. The scheme for the date/time is given to the right. Once you are done click "OK".

This returns you to the previous dialog, now click "Correlate".
