Addresses legal boundary retracement, monument recovery, and parcel description writing. Connects field evidence to property rights documentation.

Lesson 1 • GNSS Error Sources and Mitigation

Identifies atmospheric, multipath, clock, and ephemeris errors and their mitigation strategies. Error understanding is essential for selecting appropriate positioning modes.

Lesson 2 • GNSS Constellation Architecture

Describes satellite constellations, signal structure, and the ranging principle underlying all GNSS positioning. Provides the physical basis for understanding error sources and augmentation.

Lesson 3 • Differential and RTK GNSS

Covers DGNSS, RTK, and network RTK principles, initialization, and ambiguity resolution. These modes deliver centimeter-level accuracy for survey-grade positioning.

Lesson 4 • Static and Post-Processed GNSS

Explains static, rapid-static, and kinematic post-processing workflows for high-accuracy control. Post-processing enables accuracy verification independent of real-time infrastructure.

Lesson 1 • Raster Analysis and Surface Modeling

Applies map algebra, terrain derivatives, and interpolation to raster datasets. Raster analysis underpins terrain, hydrology, and suitability modeling workflows.

Lesson 2 • Spatial Data Acquisition and Input

Covers digitizing, data import formats, coordinate transformation, and quality control on input data. Clean, correctly referenced data is the prerequisite for valid analysis.

Lesson 3 • Cartographic Design and Map Production

Covers symbology, layout elements, color theory, and export standards for professional map products. Effective cartography communicates spatial findings to technical and non-technical audiences.

Lesson 4 • GIS Data Models and Structures

Contrasts vector and raster data models, topology, and attribute table design. Data model choice determines analysis capability and storage efficiency.

Lesson 1 • Spatial SQL and Query Optimization

Teaches spatial SQL functions, geometry predicates, and index strategies for efficient queries. Optimized queries are essential for performance in large enterprise databases.

Lesson 2 • Multi-User Editing and Versioning

Explains versioned editing, conflict detection, and reconcile-post workflows for concurrent data editing. Versioning enables teams to edit shared data without overwriting each other's work.

Lesson 3 • Data Sharing and Web Services

Covers OGC web service standards, REST APIs, and tile caching for spatial data distribution. Web services enable interoperability between platforms and organizations.

Lesson 4 • Relational Database Concepts for GIS

Introduces tables, keys, normalization, and joins as applied to spatial data management. Relational principles prevent data redundancy and maintain referential integrity.

Lesson 1 • Image Enhancement and Interpretation

Applies contrast stretching, band combinations, and indices to improve visual interpretation. Enhancement techniques reveal features not apparent in raw imagery.

Lesson 2 • Image Preprocessing and Correction

Covers radiometric calibration, atmospheric correction, and geometric orthorectification workflows. Preprocessing removes sensor and environmental artifacts before analysis.

Lesson 3 • Image Classification Techniques

Teaches supervised and unsupervised classification, accuracy assessment, and class refinement. Classification converts continuous imagery into discrete thematic maps.

Lesson 4 • Electromagnetic Spectrum and Sensors

Explains spectral bands, atmospheric windows, and passive versus active sensor principles. Sensor selection depends on spectral, spatial, and temporal resolution requirements.

Lesson 1 • Deliverable Generation and Quality Control

Covers orthophoto, DSM, and point cloud export, accuracy reporting, and client deliverable standards. Quality control ensures outputs meet project specifications before delivery.

Lesson 2 • Photogrammetric Geometry Fundamentals

Explains collinearity, interior and exterior orientation, and stereo geometry. These principles govern how 2D images are converted into 3D spatial data.

Lesson 3 • Ground Control and Direct Georeferencing

Addresses GCP placement, measurement, and PPK/RTK direct georeferencing for accurate model registration. Georeferencing strategy directly controls absolute accuracy of outputs.

Lesson 4 • Structure-from-Motion Processing

Walks through SfM pipeline stages: feature matching, sparse and dense reconstruction, and model export. Understanding each stage enables troubleshooting and quality optimization.

Lesson 1 • Professional Ethics and Standards

Examines professional codes of conduct, liability, intellectual property, and regulatory compliance obligations. Ethical practice protects clients, the public, and the professional's license.

Lesson 2 • Stakeholder Communication and Reporting

Develops skills in technical report writing, data visualization for non-specialists, and presentation delivery. Effective communication translates geomatics findings into actionable decisions.

Lesson 3 • Project Scoping and Specification Writing

Covers needs analysis, accuracy requirements, deliverable specification, and scope documentation. Clear specifications prevent scope creep and define measurable success criteria.

Lesson 4 • Quality Management Systems

Introduces QA and QC frameworks, inspection checklists, and non-conformance management for geomatics outputs. Systematic quality management reduces rework and protects professional liability.
