A jupyter notebook with crop analysis algorithms utilizing digital elevation models, dtm and multi-spectral imagery (R-G-B-NIR-Rededge-Thermal) from a MicaSense Altum sensor processed with DroneMapper Remote Expert.


Due to limitations on git file sizes, you will need to download the GeoTIFF data for this project from the following url: https://dronemapper.com/software/DroneMapper_CropAnalysis_Data.zip

Once that has been completed, extract the TIF files into the notebook data directory matching the structure below.

Included Data

  • data/DrnMppr-DEM-AOI.tif — 32bit georeferenced digital elevation model
  • data/DrnMppr-ORT-AOI.tif — 16bit georeferenced orthomosaic (Red-Green-Blue-NIR-Rededge-Thermal)
  • data/DrnMppr-DTM-AOI.tif — 32bit georeferenced dtm
  • data/plant_count.shp — plant count AOI
  • data/plots_1.shp — plot 1 AOI
  • data/plots_2.shp …

In this article we will process a combination of Oblique and NADIR aerial imagery using DroneMapper Remote Expert. We are working with an example imagery of Red Rocks Amphitheater, Colorado.

At 6,450 feet above sea level, Red Rocks Park is a unique transitional zone where the Great Plains meet the Rocky Mountains. Red Rocks Amphitheater is a geological phenomenon — the only naturally-occurring, acoustically perfect amphitheater in the world. Some of the rock formations in Red Rocks slope as much as 90 degrees, while others tilt backwards. The southern monolith, that bears resemblance to a ship, is named “Ship Rock.”…

DroneMapper Remote Expert is a Windows based photogrammetry software package that allows the end user to generate highly accurate 3D Models, Digital Elevation Models, Orthomosaics and Point Clouds from drone or aerial imagery. It has support for Ground Control Points, GPS EXIF and RTK/PPK EXIF tags. Today we are working with the licensed version which supports advanced features, high resolution processing and up to 1500 images per job.

We offer a completely free version of the software called RAPID that is feature limited and will process up to 150 images per job. …

NodeMICMAC is a free and open source project that allows anyone to easily process drone imagery on their native Linux install or via Docker. The project was forked from NodeODM (OpenDroneMap) and is backwards compatible with the WebODM GUI. The project provides a lightweight REST API to the very powerful underlying photogrammetry engine MICMAC, which has been in development since 2008. NodeMICMAC is developed and sponsored by DroneMapper.com as an alternative to DroneDeploy, Precision Mapper, Propeller Aero, PIX4D Cloud and other costly cloud processing services.

We recommend using a mission controller and planning application such as Map Pilot or DJI…
