Read how Serbian company GeoGIS Consultants used a senseFly eBee drone (UAV/UAS) to assess flood damage at the Kolubara lignite pit. Explore the full project story: https://www.sensefly.com/fileadmin/user-cases/2015/senseFly-Case-Study-Mine-Flood-Mapping-Serbia.pdf
4. The overflowing of the river
Kolubara also flooded part
of the Kolubara Mine Basin,
approximately 45 km (28
miles) south of Belgrade.
5. The Kolubara pit is a huge 9 km2 (3.5 mi2)
pit, part of an
estimated 540,000,000 tonnes of lignite
reserves in the Kolubara mining fields.
6. GeoGIS Consultants to supply accurate 2D
orthomosaic images & digital terrain models
(DTMs) of the flooded section of mine, in
order to calculate the best method of
draining the remaining water from the site.
7. And to plan a new river channel in order to
change its direction and prevent such
problems happening again in future.
10. Using classical surveying methods, such as
LiDAR or total stations, would have been
slow, and therefore expensive.
a terrestrial approach might have
taken 3on-site teams around 2 months.
15. They also set 25 ground control points, plus
additional field points, using independent GPS
receivers & continuous kinematics.
These measurements enabled them to fine-tune
using MicroSurvey CAD and ArcGIS.
16. 3 staff then performed
6 eBee flights.
Each flight lasted approximately
33 minutes and captured
between 180 and 250 images.
17. Since the client was very focused on
getting their data quickly, GeoGIS
managed to set all the GCPs, plan the
flights and fly them all in one day.
