National Spatial Information Management System (NSIMS)

The National Spatial Information Management System (NSIMS) is the DSG access managed repository for all DSG Spatial Information and is supported by NSIMS the Spatial Data Management Plan (SDMP).

NSIMS includes;

A spatial data metadata catalogue for searching and locating spatial and aspatial data;
A gazetteer for defining and performing searches on geographic extents of a named feature.

NSIMS Spatial Data comprises fundamental data sets (key datasets), such as Defence Master site and building floor plans, related information products or overlays and otherwise all As Constructed or consultant report documentation stored as a reference library. Every item of spatial data requires a metadata record as the primary library reference. Where applicable NSIMS key datasets are amended to reflect the new spatial content and the original data files otherwise stored for later reference. NSIMS datasets may be divided into two categories georeferenced information and geocoded key dataset information or reference.

Georeferenced Information is information aligned to a known coordinate system or as identified as a Defence site key dataset to which related information products are linked and can be viewed or queriedwith other geographic data overlays. Examples of georeferenced spatial data include:

Site level georeferenced key datasets (Defence Master Site Plans) and related underground and above ground services.
Aerial photography and Satellite imagery.
Co-ordinate locations e.g. fauna sightings, contamination locations.
Environmental mapping e.g. vegetation communities, fire management areas.
Estate Management business information overlays.

Geocoded Information is any information that can be assigned to a geographic feature. Examples of geocoded spatial data include:

Building (floor plans) key datasets related to business, services or occupancy information overlays,
Library reference datasets including Word and PDF documents, excel spreadsheets eg reports and manuals, electronic images of scanned paper plans and hand-held imagery.

How can I ensure my spatial data can be used in NSIMS?

Adopt and implement standards and specifications in the SDMP and ensure external contractor compliance for all new spatial data acquired by DSG.
