Tracing golden monkeys through time

My collegue TUYISINGIZE Deogratias (“Deo) and others at Dian Fossey Gorilla Fund International have been studying golden monkeys (Cercopithecus kandti) in Rwanda. Golden monkeys are an endangered monkey along the Albertine Rift (including the Virungas, host to the endangered mountain gorilla). They are also cute as can be, but more on that another time. Deo has been leading efforts to track the golden monkeys in … Continue reading Tracing golden monkeys through time

Latitude and Longitude of projected points in QGIS

Often one has points in QGIS in a given coordinate system and wants them in latitude and longitude for various reasons. Solutions I have used in the past included converting to WGS84 EPSG:4326 and then using the field calculator in QGIS to calculate X and Y values for Longitude and Latitude respective, exporting to CSV while projecting to 4326, or pulling into PostGIS and writing … Continue reading Latitude and Longitude of projected points in QGIS

Parallel Shells: distributing split-merge with ClusterODM #OSGeo

(Reposted from OpenDroneMap.org) Code/community sprints are a fascinating energy. Below, we can see a bunch of folks laboring away at laptops scattered through the room at the OSGeo’s 2019 Community Sprint, an exercise in a fascinating dance of introversion and extroversion, of code development and community collaboration. A portion of the OpenDroneMap team is here for a bit working away at some interesting opportunities. Tonight, … Continue reading Parallel Shells: distributing split-merge with ClusterODM #OSGeo

NodeMICMAC – a new WebODM Node

(Originally posted at OpenDroneMap Blog) Origins OpenDroneMap has an origins story rooted in a joke: While the last decade has been dominated by the growing hegemony of the global base map, mapping will swing now for a while towards the principle of mapping the world, one organic pixel at a time. 2014 is the beginning of artisanal satellite mapping, where we discover the value in 1-inch pixels from … Continue reading NodeMICMAC – a new WebODM Node

Someone has to deal with it and who you gonna call? — OpenDroneMap

Most of our blog posts on OpenDroneMap are meant for interested users. Every now and then we have a gem for our contributors / power users who like to dive into the code a bit and enhance things. For any of you who have done this, or have wanted to do this in the past… via Someone has to deal with it and who you gonna … Continue reading Someone has to deal with it and who you gonna call? — OpenDroneMap

Split-merge nearing completion — OpenDroneMap

For anyone using OpenDroneMap to process really large datasets, some good news came through early last year with improvements to how OpenSfM handles large datasets. This came in the form of an innovative, first of it’s kind, hybrid SfM method which combines the better attributes of global and incremental SfM approaches. TLDR: This helps make processing… via Split-merge nearing completion — OpenDroneMap Continue reading Split-merge nearing completion — OpenDroneMap

More code is like more cowbell — OSGeo Community Sprint

Hello from Musanze, Rwanda, a short 10 km from one of two remaining populations of Mountain Gorillas where I’ve spent the last couple of weeks with Dian Fossey Gorilla Fund International and students from University of Rwanda helping with important research in support of gorillas and biodiversity in the Virunga Massif. But, this post is not about these things (more on these later) but a … Continue reading More code is like more cowbell — OSGeo Community Sprint

View of the sea crashing on the Kerala shore

Keralite Klusters

One of the problems we worked on in Kerala wasn’t a drone problem at all, but an infrastructure problem. Given a distribution of locales, how can we cluster those according to distance to help reduced duplicated infrastructure services (internet, electricity, etc.)? There are lots of ways to solve this, but we chose to do it in PostGIS because… Ok: because that’s what I always often do … Continue reading Keralite Klusters
