Feature request MME - log file showing locations of photos

I have been flying at a location where, in some cases, the ground is rather featureless. As a result I can end up with 40 or so images all of which, look very similar even as extra large thumbnails.

Not only that but because the photos are taken normal to the flight path (and on each consecutive path this changes by 180 deg) it require a fair amount of mental effort to relate individual images to their ground locations. It is also difficult to determine when consecutive photos have jumped from one path to the next.

Obvious answer to this would be "don't worry about that - leave the mosaicing to MME and it will do the work for you".

In my case, however, this is not an option initially as there is none or highly variable cellular and/or internet coverage so investigation in the field becomes cumbersome.

It would be very useful to have a text logfile that identified the location of each image taken showing lat/lon, bearing and possibly elevation. Bearing is important as it makes it easy to immediately identify when consecutive images are on different tracks.

I can bring the Images into Picasa (for example) and their locations can be shown on a Google map but Catch 22 - this requires an internet connection.

After I wrote the above I found reference to a log file and log file viewer. It appears that this requires iTunes and a link to the iOS device which flew the mission. The computer being used to upload images may not have iTunes installed (most field office computers don't) and the iOS device is probably still mounted on the controller (which may or may not be conveniently located at the time) this seems like a pretty cumbersome approach.

Why not write the .CSV file to the SD card along with the images so they can both be transferred using a straight copy and paste?

"don't worry about that - leave the mosaicing to MME and it will do the work for you". Yep!

The log file has a few different ways of showing where the images were taken. Each time a photo is taken that log file entry has an APP_NOTE value of "Photo". This was added to make it so the photo locations will show up when using HealthyDrones for log file analysis.

Otherwise, you could just dig into the raw CSV file in Excel and sort by the APP_NOTE column for having a value of "Photo"

It is not possible to write files to the SD card. That isn't how things work on iOS. The SD card is only accessed by the aircraft.

In my case, I have clients who will want a base map showing the individual photo location and associated photo number. Like a regular air photo index map. Is there anything produced by MME that could be used to generate a spatial representation of flight lines and photo locations? Would the log file discussed above have that info?

TwoRivers: Please look into using Healthy Drones as they show a plot with the image locations based on our CSV log files.
