Hello! I see the storing of pictures inside the database as problematic - due to the pure file size to be expected, especially if it also possible to store RAW-files: Just an example from my own work (ecological study): In a project I have 16 plots studying the development of vegetation,

​Work is being done in this area, intended to be an extension of the RasterLite2 library (of the spatialite project), which will hopefully come out this year. The Raster-support in RasterLite2 supports Georeferenced images called Raster-Coverage's. The idea would be to add support for Geotaged

FYI, we are currently investigating the possibilities to link photos to geometries in QField. The idea is to use the ExternalResource widget with image flag as indicator that photos are a suitable input for this field. Then save them in a subfolder of the QGIS project + the relative path to the

Hi, I also think that there is enough interest by many people/organizations to have support for it in QGIS core. I would have the following (mostly additional) requirements: 1. being able to read a whole folder with photos 2. Support for additional graphic file formats next to JPEG.

Oh, right, good suggestion, thanks Nathan. Moreover, it can also create thumbnails: http://www.gdal.org/frmt_jpeg.html So the work from QGIS side seems considerably reduced. In the far past, reading EXIF was a bit a black magic, beacuse vendors implemented it with lots of variations, thus many

GDAL also seems to support reading EXIF information if we want to use that to avoid any extra libraries. On Mon, Jul 4, 2016 at 3:51 PM, Paolo Cavallini wrote: > Hi all, > a frequent request from user is a better management of geotagged photos. > What most users expect is

Hi all, a frequent request from user is a better management of geotagged photos. What most users expect is to: 1. be able to load geotagged photos 2. display the locations 3. display the photo clicking on the location * possibly also to show a miniature. Currently we have: * an old and relatively
