I am starting this discussion to bring to together all of the different types of software people are using to process photos collected with their drones and also what they are using it for and what limitations they are finding.
I am currently using the following software:
Agisoft Photoscan Pro
-The data I am running through it was not collected for photogrammetry so I am having some difficulties
-Some images are collected in winter with on the ground making it harder for photoscan to find matching points
-Some images do not have enough overlap or not good enough quality
-Images over forested landscapes sometimes have problems finding matching points
I have using this for quick stitching of images with too little overlap for Photoscan.
I have found it does not work well for long linear set of images
I use google earth to find coordinates for ground control points or georeferencing.
Is an open source GIS software that I use for georeferencing stitched or single images and creating data from the images
I also do a lot of work with LiDAR data and as such am very interested in classifying the point cloud that I can create with Photoscan. The new version has a tool for classifying ground points and then allowing you manually sort the rest. But I am also interested in using the one thing the advantage that photogrammetrically derived points clouds have over raw Lidar data and that is point cloud colours. I am interested in creating a work flow to classify orthos created into feature types (as can already be done) and then assigning these feature type to the point cloud that is also created.
