- ADS Python script makes a call to the Get information about schools GIAS service for data. Rather than creating a localised search and restricting the results the script asks for all data, returning all data for England.
- The service returns data in XML format, which is converted into a csv file.
- The csv is then processed by the OGR2OGR program which converts the data into a suitable format and inserts the data into a PostGIS database (spatially enabled PostgreSQL). The .VRT file effectively acts as ‘style sheet’ for OGR2OGR’s import of the csv file (which file to import, coordinate system (lat, lng).)
- The MapServer Web Feature Service (WFS) retrieves data from PostGIS (as a result of iShare or 3rd party GIS software user requests) and provides an XML/ GML output.
- iShare Maps and iShare GIS Studio administrators request the latest data from the MapServer WFS. The iShare Maps and iShare GIS Studio facilities allow the EduBase GIAS data to be displayed, as individual layers, on customer facing websites and internal intranet systems.
- The EduBase GIAS data can be displayed using other 3rd party GIS software, such as Quantum GIS (QGIS) - see WFS Client Connection Examples for details.
