ZMI — Zanzibar Mapping Initiative Level 1

The Zanzibar Mapping Initiative is the largest civilian drone mapping project in the world — an ambitious project to map the Zanzibar Archipelago using a whole host of eBee drones. The project is nearing completion of mapping Unguja, the larger of the two main islands. Because of the large area to be covered, ZMI required an approach to partition the data into manageable flight areas. … Continue reading ZMI — Zanzibar Mapping Initiative Level 1

A little Gorilla Time

I miss my mountain gorilla friends in Rwanda. Let’s write a little more code to support them. I’ll be visiting Karisoke again next week, so it seems timely to post a little more code (HT Jean Pierre Samedi Mucyo for working with me on this one). The problem today is simple — given a time series of gorilla locations and dates, can we calculate rate … Continue reading A little Gorilla Time

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, […]

Quantitative analysis of gorilla and monkey movement and R-Stat (part 3)

In my previous post, I did a bit of setup on the who and what for analyzing gorilla data. Now let’s move into R-Stat a little bit, specifically installation and configuration. For R, we’ll install whatever package is the correct one for your machine, and then also install R-Studio. This gives us a nice development […]
