Dar visit, drone fun

While I was in East Africa, I made a quick side trip to Dar to visit with some compatriots also interested in drones for good — specifically Frederick Mbuya of UhuruNet, UhuruFly, UhuruLabs, and World Bank Tanzania (etc.) , as well as Ivan Gayton, Humanitarian OpenStreetMap Team Tanzania, Missing Maps, formerly MSF UK (etc).   We chatted about tech, development, drones for good, and played … Continue reading Dar visit, drone fun

Apis helvetica var. Jacques

I was on my way to Rwanda to do some more work with Karisoke Research Institute on Gorillas, help close out some research worked on by University of Rwanda botany student Tuyizere Jean de Deiu on how land use and land cover have changed between 1995 and present. More on that project in a later post. In the meantime, while passing through Europe, I took … Continue reading Apis helvetica var. Jacques

Scaling OpenDroneMap, necessary (and fun!) next steps

I finally got PDAL properly compiled with Point Cloud Library (PCL) baked in. Word to the wise — CLANG is what the makers are using to compile. The PDAL crew were kind enough to revert the commit which broke GCC support, but why swim upstream? If you are compiling PDAL yourself, use CLANG. (Side note, […]

Finding peace, finding ground: Drone flights for hydrologic modeling

Another problem is the difficulty of turning photogrammetrically derived point clouds into Digital Terrain Models. There is proprietary software that does this well (e.g. LasTools and others), but we sought a free and open source alternative and approach. Let’s visualize the problem.
