Introduction to GIS Software and Data Models

2-3 weeks

Get hands-on with GIS software (ArcGIS Pro or QGIS). Learn vector and raster data models, attribute tables, data formats (Shapefile, GeoJSON, GeoPackage), and basic map creation.

Data Acquisition and Management

2-3 weeks

Learn to acquire spatial data from public repositories, digitize features, georeference images, and geocode addresses. Understand metadata standards, data quality, and geodatabase management.

Core Spatial Analysis Techniques

3-4 weeks

Master essential analysis operations: buffering, overlay analysis, spatial joins, proximity analysis, and map algebra for raster data. Apply these to solve real-world spatial problems.

Terrain Analysis and Surface Modeling

2-3 weeks

Work with Digital Elevation Models (DEMs) to perform slope, aspect, hillshade, viewshed, and watershed analysis. Learn interpolation methods including IDW, spline, and kriging.

Remote Sensing and Image Analysis

2-3 weeks

Study remote sensing fundamentals: electromagnetic spectrum, sensor types, image classification, vegetation indices (NDVI), and change detection using satellite and aerial imagery.

GIS Programming and Automation

3-4 weeks

Learn Python scripting for GIS using ArcPy or PyQGIS, and geospatial libraries like GeoPandas, Shapely, and Rasterio. Automate repetitive workflows and build custom geoprocessing tools.

Web GIS, Spatial Databases, and Advanced Topics

3-5 weeks

Build web maps with Leaflet and ArcGIS Online. Learn PostGIS for spatial databases. Explore advanced topics: spatial statistics, machine learning in GIS, real-time GIS, and 3D analysis.
