Is it possible to use rotate point symbols from iOS Field Maps collection?

BradBolton1

I was wondering if anyone knows or has looked into the ability to rotate points, that were captured with iOS Field Maps and including a photo? In my ideal vision, I could rotate a point symbol based on the direction the iPad was facing, when the picture was captured.

notes-the point layer and photo attachments live in ArcGIS Online. I only have a single use basic license available for desktop software. The work has already been done, so this would be after the fact.

Thanks in advance,

Brad

Try the photos to points tool, it should be able to pull out direction:

If you've got more than one photo for an actual feature, or want to show
the original point feature attributes, you might need to do some analysis
to combine that data with the photos.

Doing this for future you could use survey123 and pulldata() but it would
have to force one photo per feature with how tables and relationships
work...

If the data is in a feature field you should be able to symbolise the points with rotation using these values in the Web Map. I believe it's supported in Field Maps.

Thanks for the reply and links. Currently in my attribute table, I do not have any values to rotate the points. What I'm wondering, does the iPad camera EXIF data record the orientation of the iPad, when the picture was taken? And if so, is there a way to extract that information, to then add it back to the attribute table for the points, so I can rotate using that info?

Thanks for the help. I don't remember the exact order of steps to get to my final results, but I ended up figuring it out. Christopher, your links and info were helpful.

Something I wanted to note on here from my experience of going through this.... Our project involved adding a point in field maps, and then taking a picture, while we were constantly moving. In our case, we were moving about 3-5mph during collection. What happened, was that the exif info from the photos (using the photo to points tool to gather direction, photo xy, etc) had a different xy than the original point captured with Field Maps, due to the time it took to click the buttons and line up a picture. So, we ended up with points from the photos, with a direction, that didn't line up with the point collected with Field Maps. For us it was important that the original point be moved to the location of the photo's xy. We ended up moving/snapping the original points to the actual photo point locations. PITA-- I manually moved a few thousand of them. I'm sure there was a better way than manual.

Another thing to note, while it seemed the xy info for the photos was pretty accurate, the direction info was OK in some areas, and others, it was opposite and/or non-sensical. Since we did all of this after the collection process, we did not pay exact attention to how the device was oriented throughout the many days of collection. We used an iPad Air (5th gen). Overall, I think the direction of the points will be helpful for those that reference that information.

This was all done in an 'offline' environment.
