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(): […]

Processing point cloud in R – Follow-up



    Lab 07:  Process point cloud in R!!! In this lab, you will use the R programming language to process a point cloud.  As in previous labs, the goal is to automatically count trees across the landscape.  These methods are relevant even if you are not interested in tree-counting.  […]

Sources of airspace information Sectional Charts Download (https://www.faa.gov/air_traffic/flight_info/aeronav/digital_products/vfr/) Airspace (Ch 3 of the Aeronautical Information Manual, AIM) (https://www.faa.gov/air_traffic/publications/atpubs/aim_html/index.html). Pay attention to the airspace class definitions (3-2-3 thru 3-2-6). Excellent sectionals document by the Cessna Chick (https://cessnachick.files.wordpress.com/2013/10/howtoreadasectionalchart1.pdf) You must know: Class definitions Vertical limits Operational restrictions Class B ‘Bravo’ Class C […]

Sectionals – working list…


Monday, you stepped through a simple analysis in ArcMap.  You created a normalized surface model (I called it the DZM in the lab document) by differencing the surface model (DSM) and the terrain model (DTM).  The resulting raster layer contains cells whose values are 0 or near-zero.  These cells represent […]

SeGrowers Data Processing in R – Demo



In this lab, you will generate a point cloud and an orthophoto from photos captured during one of my UAV flights last November. You will use the LiDAR toolset in Global Mapper to generate a bare ground “terrain” model and a “surface” model (includes trees, stumps, buildings, etc). ——————————————————————————— Create […]

FANR5640/7640: Lab 5 – Global Mapper Pixels to Points


    The Basic Physics of Drones   Now, the effects of loading and weight on aircraft (sUAS) performance Flying an aircraft overweight is detrimental to its performance It is critical to adhere to the weight and balance limits specified by the manufacturer of your aircraft  (you will see this document […]
