Transforming Geospatial Data Management: From Model to Service using FSDF Framework

This document outlines the comprehensive process involved in converting geospatial data models into functional services utilizing the FSDF framework. It details the interactions between various components such as JSON, WFS, WMS, and GeoServer for effective data storage and retrieval. Key aspects include the establishment of spatial relationships between governance units (countries, states, LGAs), modeling hierarchies, and addressing challenges posed by offshore LGAs. Furthermore, it highlights the importance of schema mapping and the integration of complex feature types within the geospatial data ecosystem.

  2. FSDF Process: Model  Service JSON WFS WCS WMS JSON GeoServer ESRI SHP GML Mapping File Data Source FSDF Data Store XML (GML) App Schema XSD (GIS) Database FSDF Mapping + WFS Product Model Geospatial Queries UML FSDF Model PSMA ABS UML

  3. Section 1:FSDF Data Store

  4. Building a FSDF Data Store • Spatial Rel.: • State ↔ State • State ↔LGA • LGA ↔LGA FSDF SPATIAL <gml:Point gml:id="Point1"> <gml:pos srsName= "urn:epsg:crs:62836405"> 30.440 36.889 </gml:pos> </gml:Point> • Governance Units • Country, State, LGAs • Statistical Units • MB, SA1, SA2 … FSDF AREA FSDF UNIT “There are some LGAs which extend significantly offshore, hence their centroid does not lie within the state polygon, so they were not picked up in the spatial query…” • Hierarchies: • Country ↔ State • State ↔LGA FSDF HIERARCHY Table Def. Table Data

  5. Spatial Rel. Example: Adjacency State NSW LGA Y(Corowa) LGA X (Moira) Locality Y(Castle Creek) LGA Z • Adjacent: • LGA X adjacent to LGA Y (within datasets) • State NSW adjacent to State VIC • LGA X adjacent State NSW (across datasets) • LGA Z adjacent Locality Y State VIC

  6. Summary: Data Store Model FSDF SPATIAL FSDF HIERARCHY FSDF UNIT

  7. Section 2:FSDF Mapping + WFS

  8. Mapping Complex Feature Types GeoServer App Schema Plugin WFS / WMS / WCS Product Model Schema Mapping File
