UAS 205 - Generating DSMs and Orthomosaics

These flashcards cover key terms and concepts from UAS 205, focusing on the techniques and tools used in generating digital surface models and orthomosaics from UAV imagery.

UAV (Unmanned Aerial Vehicle)

An aircraft that operates without a human pilot on board, typically used for capturing aerial imagery.

Orthomosaics

Seamless aerial maps created by stitching together overlapping images, corrected for geometric distortion.

Digital Surface Models (DSMs)

3D representations of the terrain derived from UAV imagery, including buildings and vegetation.

Ground Control Points (GCPs)

Surveyed points with known geographic coordinates used to align and improve the accuracy of UAV-derived mapping products.

Photogrammetry

The technology and process of obtaining reliable measurements through the interpretation of photographic images.

Post-Processing

The stage following data collection, where raw data is transformed into usable, georeferenced outputs.

Georeferenced Outputs

Digital representations of data that include geographic coordinates for spatial accuracy in mapping.

Image Matching Algorithms

Computational methods used to identify corresponding points in multiple images to create 3D representations.

Exchangeable Image File Format (EXIF)

A standard format for storing metadata in image files, including GPS coordinates and camera settings.

Cloud-Based Processing

Using internet-based services to process data, reducing the need for high-performance hardware on the user's end.
