Reconstructing cliffs in OpenDroneMap, or how to beat LiDAR at its own game

LiDAR and photogrammetric point clouds If we want to understand terrain, we have a pricey solution and an inexpensive solution. For a pricey and well-loved solution, LiDAR is the tool of choice. It is synoptic, active (and therefore usable day or night), increasingly affordable (but still quite expensive), and works around even thick and tall evergreen vegetation (check out Oregon’s LiDAR specifications as compared with … Continue reading Reconstructing cliffs in OpenDroneMap, or how to beat LiDAR at its own game

OpenDroneMap in Côte d Ivoire for UR Afrique de l ouest et centrale and State of the Map Africa

I had the pleasure a couple weeks ago of attending the sibling conferences Understanding Risk West and Central Africa and State of the Map Africa in Côte d’Ivoire (Ivory Coast) a few weeks ago. It included a nice mix of formal discussions of how to reduce risk in light of climate change, as well as discussions of all aspects of OpenStreetMap efforts. The conferences were … Continue reading OpenDroneMap in Côte d Ivoire for UR Afrique de l ouest et centrale and State of the Map Africa

Wrasseling with the Passel

American Red Cross International Services Division continues their development of Portable OpenStreetMap, or POSM, in the latest 0.9 release. The concept is simple: use the full ecosystem of OpenStreetMap tools and sibling projects to deliver better geospatial data for aid and recovery wherever Red Cross goes. In the case of integration of OpenDroneMap, the challenge has been one of compute power: how does one, for … Continue reading Wrasseling with the Passel

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
