Après la saison de verrouillage dur du COVID-19, le bureau de 3DroneMapping en Ouganda a lancé une étude aérienne de 28 000 ha d'un domaine de canne à sucre.Le domaine avait besoin des services de 3DroneMapping pour produire une modélisation numérique du terrain (DTM) et des orthophotographies très précises.Ces produits devaient à leur tour être utilisés par les ingénieurs agricoles pour la planification et le développement de systèmes d'irrigation ainsi que pour un usage int

Post COVID-19 hard-lockdown season has started up with 3DroneMapping's Uganda office undertaking a 28 000ha aerial survey of a sugar cane estate. The estate required the services of 3DroneMapping to produce highly accurate Digital Terrain Modelling (DTM) and orthophotos. These products were in turn to be used by agricultural engineers for the planning and development of irrigation systems as well as for internal use by the estate to maintain and understand the drainage patter

Chez 3Dronemapping, on nous demande souvent comment nos données et nos produits finaux se comparent au LiDAR traditionnel capturé à partir d'avions pilotés. Chacune des méthodes et des instruments utilisés pour générer des ensembles de données a ses avantages et ses inconvénients. Certains sites de projets pourraient être mieux adaptés au LiDAR tandis que d'autres bénéficieraient de PhoDAR. Cet article espère indiquer les différences entre les méthodes de capture des donné

At 3Dronemapping, we often get asked how our data and end products compare to traditional LiDAR captured from manned aircraft. Each of the methods and instruments used to generate datasets have their own pros and cons. Certain project sites may be better suited to LiDAR while others would benefit from PhoDAR. This article hopes to indicate the differences between the methods of data capture and suggest where each is best utilized. LiDAR (Light Detection and Ranging), is a rem

3DroneMapping a récemment été appelé pour cartographier une mine de graphite proposée très éloignée en Afrique de l'Est. Le client a donné une fenêtre très courte pour que l'enquête soit entreprise car il avait besoin de cette information pour commencer la planification des emplacements de forage, de l'établissement du camp et de la conception de la route d'accès. À l'aide d'une plate-forme à voilure fixe construite sur mesure avec un capteur de format moyen, un enregistreur

3DroneMapping has recently opened its doors in Uganda. This strategic move is to supply the growing demand for affordable and high resolution aerial surveys in East and Central Africa. Assisted by our partners in East Africa, we have been able to offer much reduced site establishment costs as well as far quicker response times for our clients. Uganda is very well geographically positioned with easy access to a number of neighboring countries such as Democratic Republic of Con

Les données dérivées de la photogrammétrie des drones sont excellentes. Il est riche en fonctionnalités et contient souvent plus d'informations que vous n'en auriez jamais besoin. Les nuages ​​de points sont parfois si denses qu'ils peuvent dépasser 50 points par mètre carré. Mais toutes ces données haute définition valent-elles vraiment beaucoup pour le client final et sont-elles comparables aux sorties traditionnelles des levés terrestres ou LiDAR? Certains logiciels de

Data derived from drone photogrammetry is great. It is feature rich and often contains more information than you would ever need. Pointclouds are at times so dense that they can exceed 50 points per square meter. But is all this high definition data really worth much to the end client and is it comparable to traditional outputs from terrestrial survey or LiDAR? Some photogrammetry software allows for moderate filtering of tie-points that makes up the final pointcloud. While t

Une grande partie de notre temps chez 3DroneMapping est consacrée au bureau, traitant des données. Nous avons travaillé avec des téraoctets d'informations au fil des ans, vu le développement et l'évolution des logiciels, du matériel et des exigences finales générales de nos clients. Parce que nous sommes dans l'industrie depuis si longtemps, nous avons acquis une expérience précieuse et avons une solide compréhension de la photogrammétrie et des routines SIG. Notre bureau a

Much of our time at 3DroneMapping is spent in office, processing data. We have worked with terabytes of information over the years, seen the development and evolution of software, hardware and the general end requirements of our clients. Because we have been in the industry for such a long time, we have gained valuable experience and have a solid understand of photogrammetry and GIS routines. Much of our time at 3DroneMapping is spent in office, processing data. We have worke

Using long range high precision drones to analyse slope stability, quantify property damage and design preventative structures.

In late 2018, the Bududa region in Eastern Uganda experienced torrential rain for a number of days. The area falls just outside of Mount Elgon National Park on the Kenyan border and is characterized by its extinct volcanic crater, dense tropical rain forest and very intensive agricultural activities on steep slopes. Given the high saturation of the soil and large mass of water, landslides where experienced in the area, causing major damage to property. Already saturated mud f

3DroneMapping a récemment terminé un levé aérien assez simple en République démocratique du Congo. Le site de 60 ha est adjacent au fleuve Congo et offre une vue imprenable sur Kinshasa, la capitale ainsi que Brazzaville dans la République voisine du Congo. L'enquête a nécessité une production d'orthophoto et de contour. Après des observations géodésiques pour assurer une géolocalisation absolue précise, un RPA à voilure fixe a été déployé pour capturer des images haute résol

3DroneMapping recently completed a fairly simple aerial survey in the Democratic Republic of the Congo. The 60ha site is adjacent the Congo River and has amazing views of of Kinshasa, the capital city as well as Brazzaville in neighboring Republic of the Congo. The survey required orthophoto and contour production. After geodetic observations were done to ensure accurate absolute geolocation, a fixed wing RPAs was deployed to capture high resolution images of the site. Since

3DroneMapping has been testing and setting up their new full-frame, 42MP sensor with distortion-free 35mm lense

3DroneMapping has been testing and setting up their new full-frame, 42MP sensor. This camera combined with a flat, distortion free lens has revolutionized our work flow and given unheard of accuracies. Over the years, we have had reliable sensors that will work in trying conditions like high heat, dust, vibration, etc. We have always tried to keep at the very edge of available technology since our clients do not pay us to fly but to produce accurate and consistent data. Our e

Testing of PPK for accurate ground control-less surveys done from drone based aerial survey.

3DroneMapping has been testing a PPK system for the past year. The point of PPK (or Post Processing Kinematic) is not just to improve internal photogrammetric model orientations, but also is general recognised as a way of undertaking full-scale surveys at the same accuracy but without having to place time-consuming ground control points. 3DroneMapping setup a calibration site to test the claims made by manufacturers and ultimately for our own quality assurance that what we pu
