Derives DSMs and DTMs from point clouds and validates them against ground truth. Elevation models support terrain analysis, volume computation, and mapping.

Lesson 2 • Orthophoto and Mosaic Generation

Produces orthorectified imagery and seamless mosaics for planimetric mapping. Orthophotos serve as base layers for GIS and feature extraction workflows.

Lesson 3 • Exterior Orientation and Aerial Triangulation

Covers ground control points, tie points, and bundle adjustment for image orientation. Accurate exterior orientation enables precise 3D reconstruction.

Lesson 4 • Camera Geometry and Interior Orientation

Explains focal length, principal point, and lens distortion parameters. Interior orientation is the foundation for all photogrammetric measurement.

Lesson 1 • GIS Data Models and Structures

Contrasts vector and raster data models, topology, and attribute tables. Data model choice governs analysis capabilities and storage efficiency.

Lesson 2 • Spatial Database Design and Queries

Designs geodatabases with feature classes, domains, and relationship classes. Structured queries enable efficient retrieval of spatial and attribute information.

Lesson 3 • Vector and Raster Spatial Analysis

Applies overlay, buffer, network, and raster algebra operations to solve spatial problems. Analysis results directly inform planning and engineering decisions.

Lesson 4 • Spatial Data Acquisition and Integration

Covers digitizing, data import, format conversion, and coordinate system alignment. Integrated datasets enable multi-source spatial analysis.

Lesson 1 • Boundary Evidence and Retracement

Identifies physical, documentary, and testimonial boundary evidence and retracement principles. Evidence evaluation determines the legal position of boundaries.

Lesson 2 • Boundary Survey Computation

Performs metes-and-bounds, lot-and-block, and subdivision calculations. Computational accuracy ensures parcel areas and dimensions meet regulatory tolerances.

Lesson 3 • Cadastral Mapping and Parcel Fabric

Creates and maintains digital parcel fabrics integrated with spatial databases. Accurate parcel maps support land registration and property taxation.

Lesson 4 • Cadastral Concepts and Land Tenure

Explains parcel identification, land tenure systems, and cadastral record structures. Conceptual grounding is required before conducting boundary surveys.
