Overview of Geo-Informatics Labs:
A GIS (Geographic Information System) software, like ArcMap, allows users to capture, store, manipulate, analyze, and visualize geographic data, essentially creating maps with layers of information overlaid on a geographic base, enabling spatial analysis and decision-making across various fields like urban planning, environmental studies, and civil engineering; this course will cover the fundamentals of using ArcMap, including installation, basic map creation, working with projections, digitizing data, spatial analysis tools, table operations, incorporating satellite imagery, and applying GIS techniques to land use/cover mapping and change detection, with a focus on practical applications within civil engineering projects.
Key topics covered:
- Introduction to GIS Software:
- What is GIS, and what are its core concepts (vector data, raster data, spatial reference, topology)?
- Understanding the ArcGIS platform and its components (ArcMap, ArcCatalog, ArcToolbox)
- Installing ArcMap Software:
- Downloading and installing ArcGIS Desktop (including ArcMap)
- Setting up licensing and accessing data sources
- Working in ArcMap and Map Making:
- Navigating the ArcMap interface
- Adding data layers (shapefiles, geodatabases, rasters)
- Symbology and visualization techniques (color schemes, point patterns, line styles)
- Creating map layouts and annotations
- Working with Projections:
- Understanding coordinate systems and datum
- Defining spatial reference for data
- Projecting data to different map projections (e.g., UTM, State Plane)
- Digitizing in ArcMap:
- Enabling editing mode and digitizing tools
- Tracing features from scanned maps or aerial imagery
- Creating new features (points, lines, polygons)
- Geo Referencing:
- Aligning scanned maps to real-world coordinates
- Using control points to accurately geo-referenced data
- Spatial Analysis and Geoprocessing:
- Performing basic spatial queries (select by location, attribute query)
- Utilizing geoprocessing tools for buffer analysis, overlay analysis, and distance calculations
- Digital Data and Tables:
- Understanding attribute tables and their relationships to spatial features
- Performing table operations (join, relate, calculate field)
- Spatial selection and searching:
- Selecting features based on spatial location or attribute values
- Using spatial selection tools for analysis
