Datums: The Foundation of Geospatial Reference Systems
geodetic datums, horizontal datums, vertical datums, geodetic reference frames
1. Definition and Purpose of Datums in Geospatial Analysis
reference points, coordinate systems, spatial relationships
2. Commonly Used Horizontal Datums: NAD83 vs WGS84
North American Datum 1983 (NAD83), World Geodetic System 1984 (WGS84), differences between NAD83 and WGS84
3. Vertical Datums: Understanding Height References in Geospatial Analysis
orthometric height systems, geoid models, ellipsoidal heights
The Role of Map Projections in Remote Sensing and GIS Applications
map projections types, coordinate systems transformations,
1. Introduction to Map Projections: Transforming 3D Earth onto a 2D Plane
cylindrical projections, conic projections , azimuthal projections
2. Commonly Used Map Projections for Remote Sensing and GIS Applications
Mercator projection , Lambert Conformal Conic projection, Universal Transverse Mercator (UTM) projection
3. Considerations When Choosing a Map Projection for Surveying and GIS Analysis
scale distortion, area distortion, shape distortion, suitable projections for different regions
