Work Education Provision Planning

An Interactive web map featuring tools for spatial analysis

The CartoDB visualisations have proved to be the best solution for understanding the spatial components of school provision analysis.

Spatial analysis

We built a series of interactive web maps, featuring tools for spatial analysis, for the Department of Education and Early Childhood Development (DEECD).

New suburbs on the outer limits of the urban environment, demographic change in established suburbs, and varying enrolment choices are just some of the factors impacting education provision across the state.

Tabular-based analysis can be used to investigate the many factors described above. The spatial factors of this analysis are not easily understood in a tabular form.

Data Analysis

We chose CartoDB as the web mapping and data analysis solution for its capacity to support dynamic maps, and the option to analyze and build location aware and geospatial applications.

CartoDB is a Software as a Service (SaaS) product in the cloud; data is uploaded to CartoDB and data is cartographically styled, analysed and shared across the web.

Visualisation with Voronoi (or Thiessen) Polygons

Voronoi polygons are a way of dividing space into a number of regions based on seed points. 

Any location within a Voronoi polygon is closer to its associated point than to any other point input feature.

Voronoi Polygons are used to create service areas for schools, where the regions represent the nearest school location. These service areas are used to present demographics and enrolment counts spatially across Victoria.

Spatial data editing

We used QGIS for spatial data editing as well as the integration of the GRASS GIS Plugin, an open source GIS used for geospatial data management and analysis. The GRASS Plugin includes a Voronoi Polygon processing tool.

QGIS is a free and open source desktop geographic information systems (GIS) application that provides data viewing, editing, and analysis capabilities.

Result

The project proved to be a great success within the department, allowing for data to be visualised in an interactive medium and shared throughout the organisation.

The CartoDB visualisations have proved to be the best solution for understanding the spatial components of school provision analysis.
