ASPRS Workshops

ASPRS UAS Workshops

Presented by The American Society for Photogrammetry and Remote Sensing (ASPRS)  
Monday, October 28th | 8:00 AM - 12:00 PM and 1:00 PM - 5:00 PM  
Space is limited. Registration Required.

The American Society for Photogrammetry and Remote Sensing (ASPRS) will be hosting two sessions at this year’s event. Read the full descriptions for both sessions below. 

*Register for the workshops when you register for the expo. The ASPRS UAS workshops are offered as add-on items to either a Full Conference or Exhibits-Only registration for Commercial UAV Expo Americas.

Part I: Introduction to UAS Mapping (Lidar and Photogrammetry

Monday, October 28 | 8:00 AM – 12:00 PM


1. Intro to ASPRS

2. Mapping Concepts – Coordinate Systems

– Datum Definitions; Ellipsoid vs Geoid vs MSL; Map Projections – UTM, State Plane Mapping;

Why is elevation so important in Mapping?

3. Mapping Concepts – Errors and Statistical Measures

Error Characterization; Biases and Blunders; Random Errors / Gaussian Distribution; Accuracy vs

Precision; Why is it so important to know

4. Mapping Concepts – Photogrammetry

Standard Mapping Products; Geometric Resolution / Radiometric Resolution; Image

Georeferencing Aerial Triangulation; PPK – Assisted Aerial Triangulation; DG – Direct

Georeferencing; ISO – Integrated Sensor Orientation; Overlap /Sidelap; Fixed

wing/VTOL/Aircraft, etc; Fly altitude; Camera type/quality; Sensory resolution/pixel size; Rolling

Shutter/Mechanical Leaf Shutter; Ground Control Points; Basic Photography 101; Shutter speed,

ISO, Aperture

5. Mapping Concepts – Lidar

Definitions; LiDAR Sensor overview and General Applications; LiDAR Workflow; LiDAR-Derived

Accuracy Assessment

Session II: Advanced UAS Mapping (Lidar and Photogrammetry)

Monday, October 28 | 1:00 PM – 5:00 PM


1. Theory Vs Reality

Malfunctioning Sensors; Misinterpreted Results; Failed Project Planning and Layout

2. Putting Theory to Work – Photogrammetry

DJI Drones (benefits and drawbacks); Vertical Offsets and Datum Issues; Stereo vs Automated

Matching; Human vs Machine; Interpreting Aerial Triangulation (AT) Reports; Checkpoints and

their value; Real World Examples; Image Texture/Coloration; GCP Placement; Large Scale Project

Processing; Correlated Parameters; What to look for!; How to Avoid Mistakes!;
