Lab 11 RedEdge – Follow-up   We’ve just flown a RedEdge mission out at Lake Herrick resulting in 275, 5-band multispectral images.  Many of the images were acquired using a vertical flight pattern (5m AGL, 6m AGL, …, 200m AGL). The raw imagery has been converted to percent reflectance (DN […]

Lab11 – MicaSense RedEdge-M – Follow-up

    The MicaSense RedEdge-M a specialized sensor capable of recording reflected energy in the visible blue, green and red wavelengths as well as the non-visible red edge and near-infrared portions of the electromagnetic spectrum. Typical response of healthy plants, when compared to stressed plants, is lower in the visible […]

Sectionals – Special Use Areas

  Monday, you had an opportunity to process a drone-based point cloud using R and the lidR and the rgdal packages.  You should have familiarized yourself with the following commands and at least have an idea of what they do: plot() summary() lasfilterdecimate(): https://www.rdocumentation.org/packages/lidR/versions/2.0.0/topics/lasfilterdecimate lasground(): https://www.rdocumentation.org/packages/lidR/versions/2.0.0/topics/lasground lasnormalize(): https://www.rdocumentation.org/packages/lidR/versions/2.0.0/topics/lasnormalize lasfilter(): https://www.rdocumentation.org/packages/lidR/versions/2.0.0/topics/lasfilters grid_metrics(): https://www.rdocumentation.org/packages/lidR/versions/2.0.0/topics/grid_metrics grid_canopy(): […]
