Spatial Data Processing and Analysis

This unit develops hands-on skills for preparing, managing, symbolizing, and analyzing vector and raster spatial data in ArcGIS. Students will convert and validate datasets, manage projections and topology, apply raster and vector analysis tools (distance, density, raster calculator), and produce styled map outputs and reports to support site-selection and spatial decision-making.

Learning Objectives

• Apply geodatabase workflows and topology tools to convert shapefiles to feature classes, validate and correct topological errors, and georeference layers for use in analysis
• Demonstrate map design and communication skills by changing layer properties, applying styles and classification, producing charts and reports, and exporting print-ready map products
• Analyze raster and vector datasets using Spatial Analyst functions (Euclidean distance, raster calculator, density, dissolve, and zone-to-region conversions) to identify and prioritize candidate sites based on cost, distance, and density criteria
• Evaluate coordinate systems, projection, scale, and resolution issues and apply appropriate reprojection, GPS integration, and feature positioning techniques to ensure spatial accuracy
