A project GIS is a geographic information system that is constructed to accomplish a specific task or undertaking. Unlike an Enterprise GIS, which is a permanent system for permanently managing geographic information for a variety of ongoing applications, a project GIS is temporary.
Project GIS workflow
Although a variety of workflows have been developed for solving analytical tasks, such as the PPDAC Model, they generally follow the following process:
- Clearly define the problem to solve, whether it is a scientific research question or a resource management decision.
- Collect the necessary Spatial Data, either through data entry or gathering existing data from another source. Unlike an Enterprise GIS, designing a Data model is not as crucial in a project GIS.
- Preprocess the data into a form required for the analysis. This may include steps such as changing the Coordinate system, changing from one Data model to another, and Attribute reclassification.
- Spatial analysis procedures are performed to solve the given task.
- The results are reported.
After the goals are accomplished the data is no longer needed and can be discarded or archived.
