I'd like to invite the diydrones members to participate in a project I started on github: Project Ion on github
The control of uav's have improved a whole lot in the past couple of years and you can now pretty much put one in the air and wait for the results to come back, whether these are videos or images. There are numerous posts and videos of people who show how they made orthomosaics, 3D models, point clouds and digital elevation models.
I started Project Ion with that motivation in mind; thinking from the perspective of your customer (or your own needs), how do you grab the orthomosaic / DEM you just created and start to answers the real questions that end users have and answer those questions in a visually compelling way? Not every office contracts a bunch of engineers to work with ortho and DEM data.
The work above was done with a team of experienced surveyors. In this case I played a supporting role to provide them with the orthomosaic, which was for visualization purposes. They used the geo-referenced ortho themselves to validate their collected data points. Since I have my own methods to derive an accurate set of control points, you get two disjoint data sets which have no dependency on one another. Here, I'm just demonstrating how the ortho could be annotated with help of some of their survey points to better visualize the land and the boundaries. In many cases, surveyors provide an iconic diagram of the land made in autocad and they don't have acces to a recent ortho. So it makes sense to also think towards support roles for uav in surveys, where the orthomosaic is just used as a means of cross validation and visualization of the results.
Another thing that came up is that the area had recently been leveled. They were interested in the accuracy of this leveling. With a contour map, you can easily process the DEM to extract these contour lines at any interval. Of course, everything can be exported to CAD tools for further processing.
All images above were made with the help of QGIS, now starting to become a very powerful GIS application with a bunch of plugins for many different purposes.
So I'm looking for contributors to set up this knowledge base. Not everything has to be written as a tutorial on the wiki, the idea is to link to existing content, link to videos and just show what others have done, generate ideas and make it a wiki that you can browse to find really cool applications that go further than orthomosaics from pix4d/photoscan, then explain how such resuls are achieved, etc. I'm not excluding that the project develops some of its own scripts and tools to faciliate in that process.
How to become a collaborator? Send me a privmsg on diydrones if you're interested and your github username so I can add you as a collaborator on github. If you don't have a github account and want to send me a cool link to some video or tutorial on how uav data is being used or applied, feel free to send this in a privmsg as well.
