OzGIS is a highly specialized, lightweight, and free geographic information system (GIS) designed primarily for analyzing and displaying socio-economic and demographic attribute data as maps and diagrams. Originally built to map census bureau data, it allows beginners to handle spatial mapping without the heavy resource consumption of massive suites like ArcGIS or QGIS.
This beginner’s tutorial walks you through setting up and running your first mapping project in OzGIS. Step 1: Download and Installation OzGIS operates as a lightweight Windows application.
Download the software: Get the official version completely free from the OzGIS SourceForge Repository.
Install: Unzip the downloaded file or run the installer executable. Follow the default prompts to complete installation.
Launch: Open the application via your desktop shortcut or Windows Start Menu. Step 2: Prepare Your Data Structure
Unlike modern software that allows you to drag and drop random files, OzGIS relies on a specific structural relationship between spatial data (the map shapes) and attribute data (the numbers you want to map).
Spatial Files: Ensure you have base map files (such as shapefiles or boundaries provided by census bureaus or mapping agencies).
Attribute Files: Prepare a matrix or table format containing the quantitative details you want to visualize (e.g., population count, average household income, or environmental indexes).
The Shared Key: Your attribute file must contain a matching ID or name column that exactly matches the boundaries of your spatial file so the software knows where to project the numbers. Step 3: Load the Base Boundary Map
Before displaying your data, you need to tell the software what geographic region you are analyzing. ArcGIS Pro Full Beginner’s Course (2025 Extended)
