SMALL DRONES + SMALL CAMERAS + STRUCTURE FROM MOTION + SMALL ENTERPRISES = MAPPING REVOLUTION

Last week, in Naples, Fl., at the AGM of the Florida Surveying and Mapping Society (FSMS) our sister company drone2GIS Inc. showcased a cross section of it's leading edge drone derived geo-spatial products . Have a look at the video here: …

USING DRONES FOR SAFER SURVEY AND MAPPING WORK ON TRANSPORTATION CORRIDORS

We recently tested our Structure from Motion (SfM) and Virtual Surveying approach in a road survey scenario. The only significant manual work in the field was to survey ground control and check points. Image acquisition (with a Pixhawk equipped quad copter and a 24Mp camera) as well as SfM processsing was a highly automated exercise that quickly produced BIG data. To extract…

HOW ACCURATE ARE YOUR MAPS AND MODELS?

Making maps with the help of small UAVs seems to be easy enough. However, when geometric accuracy is critical, how do you determine and state the estimated accuracy of your mapping product? One way is to establish a test bed with a redundancy of accurately surveyed check points which are used as independent bench marks against which the map can be compared. In this…

Small Drones accelerate and improve stockpile reporting for mines and earth work supervision.

Not only are they the safest, quickest method of quickly taking a snapshot of an entire highly dynamic site, they significantly reduce surveying costs. Adding powerful structure from motion (SfM) software and virtual survey tools to the equation means no boots on the ground and no need for interrupting any operations.

PIXHAWK, QU4D X, BATELEUR, PHOTOSCAN, VIRTUAL SURVEY TOOLS

An example of the new geo-spatial products and virtual surveying and planning tools which we can bring to the farmer's kitchen table today - safely, harmlessly and economically, over and over again. All thanks to small UAVs - the new personal mapping systems. Thanks to the tremendous contributions from the DIY Drone community, small enterprises can now offer new cost saving…

World class small enterprise map production performance in Namibia.

Last Friday I had fun witnessing Diether Engelhard and Andreas Breitenstein pulling off four 1hr flawess flights in one day with their APM1 equipped X8 to map some 900 hectares of farmlands in Namibia. The X8 covered a total distance of 240km to provide high resloution aerial imagery - altogether some 9000 20MP images captured with a Samsung NX 1000 camera. This is a classic example of how small, private sector enterprise entrepreneurism and initiative can lead a country to…

Urban Mapping with a small APM 2.6 controlled quad drone

Above is a video of a presentation we recently gave about the work we did for the World Bank in Albania. It shows that small drones are much more than toys - they have become productive tools for innovative surveyors.
