Utilizing Geo-Photomap Multi-Spectral Sensors in Precision Agriculture

Geodetics’ new drone for photogrammetry Geo-Photomap is a new technology offered in the Geo-MMS Drone LiDAR Mobile Mapping System product suite. Geo-PhotoMap tightly integrates GPS/IMU with RGB imagery resulting in direct-georeferencing of the captured images, allowing the capability of precision agriculture. It is now available with multi-spectral sensors. With Geo-Photomap, the change from RGB to multi-spectral is as simple as Plug&Play of the camera lens, as shown below. By turning CE DSLR cameras into high-end multi spectral sensors with NDVI & Red Edge Lens technologies, Geo-Photomap becomes an ideal tool for advanced precision agriculture applications.

Similar to the how RGB images are captured and time-tagged with Geo-Photomap, multi-spectral images are also time-tagged and geo-tagged. The geo-referenced images are then post-processed, generating an accurate and precise orthomosaic without the use of ground control points (GCP-free). This new drone for photogrammetry Geo-Photomap capability supports many new applications, including agriculture (canopy classification), forest planning and management (fire, precision forestry), environmental assessment, ecological & land Classification, etc. Photogrammetry, can generate full-color 3D and 2D models (in the various light spectrum) of the terrain that is easier to visualize and interpret.
