Geospatial Mapping & Visualisation#

Overview#

The map is the common language of operations. An analyst describing a pattern in a spreadsheet struggles to communicate the same insight that becomes immediately obvious when the same data is displayed geographically. An operations room where every screen shows a different view of the same situation loses the shared understanding that enables coordinated decision-making. The Mapping & Visualisation module provides the single, authoritative geographic picture that grounds every operational discussion.

High-performance rendering handles large simultaneous datasets without degradation. Real-time data overlays keep the picture current as situations develop. Heat mapping, point clustering, and temporal playback transform raw location data into the kind of intelligence that drives decisions at every level, from a dispatcher choosing the nearest unit to a commander planning next month's resource deployment.

Key Features#

High-Performance Rendering#

Smooth visualisation of large point, line, and polygon datasets simultaneously without frame drops
Progressive loading renders visible data first for immediate interaction
Level-of-detail adjustment automatically simplifies display at lower zoom levels
GPU-accelerated rendering for demanding visualisation scenarios including CesiumJS 3D terrain
Cross-browser and cross-device compatibility including mobile and vehicle-mounted displays

Dynamic Data Overlays#

Real-time position markers for tracked entities with speed, heading, and status indicators
Incident and event markers with severity-based styling and age indicators
Route and path visualisation for movement analysis
Boundary and territory polygons with fill and outline styling
Custom icon libraries for organisation-specific entity types

Heat Mapping#

Continuous density surface rendering from point data
Configurable radius, intensity, and colour gradient parameters
Real-time heat map updates as underlying data changes
Multi-layer heat maps for comparative density analysis across time periods or categories
Statistical validation of density patterns through kernel density estimation

Point Clustering#

Automatic grouping of dense point concentrations at lower zoom levels for readability
Cluster size indicators show aggregate counts at a glance
Click-to-expand reveals individual points within clusters
Spiderfication displays overlapping points in an accessible arrangement
Category-aware clustering groups similar entities together

Temporal Playback#

Animate geographic data over configurable time periods with smooth transitions
Playback speed controls for fast overview or frame-by-frame detailed analysis
Timeline scrubbing for direct navigation to specific moments
Temporal filtering shows only data from selected time windows
Side-by-side temporal comparison of different periods or scenarios

Interactive Analysis Tools#

Distance and area measurement tools for on-map calculation
Drawing tools for defining areas of interest, routes, and annotations
Feature selection and inspection with detailed attribute display
Print and screenshot capture for reporting and briefings
Bookmark and share specific map views with team members for collaborative analysis

Use Cases#

Incident Response#

Operations centers display real-time incident locations, responding unit positions, and affected areas on a shared map for coordinated response management and resource deployment. All participants see the same picture updated in real time.

Investigation Mapping#

Investigators plot case-related locations, entity positions, and event timelines on interactive maps to discover spatial patterns and geographic relationships across investigation data that would be invisible in a case file.

Operational Briefings#

Leaders use map visualisations in operational briefings to communicate geographic context, resource deployment, and activity patterns to diverse audiences including non-technical stakeholders. A heat map makes the argument for resource redeployment faster than any chart.

Real-time data feeds for live entity tracking and incident display
Alert systems for geographic notification display on the operational map
Case management platforms for investigation mapping and evidence visualisation
Dispatch and CAD systems for resource position visualisation
ArcGIS and GeoServer for enterprise GIS data integration
CesiumJS for 3D terrain visualisation in topographically complex operational areas
Reporting tools for map export and presentation generation

Open Standards#

GeoJSON (RFC 7946): All geographic features, points, lines, polygons, and geofences, are stored and exchanged in GeoJSON format, including PostGIS round-trips via ST_AsGeoJSON and ST_GeomFromGeoJSON.
OGC API Features (OGC 17-069r4): The platform connects to OGC API Features endpoints to discover and synchronise feature collections, consuming the standard /collections and /collections/{id} resource paths.
OGC Web Map Service / Web Feature Service (WMS / WFS): GeoServer integration is explicitly implemented as an OGC web-services bridge, syncing layer metadata with EPSG-declared spatial reference systems across WMS and WFS-compatible endpoints.
OGC 3D Tiles: CesiumJS integration fetches and registers 3D tileset assets from Cesium ion or compatible OGC 3D Tiles servers, enabling GPU-accelerated 3D terrain and urban-model overlays on the operational map.
STANAG 4676: The tracks domain ingests and exports STANAG 4676 JSON and XML TrackMessages, allowing NATO-format multi-sensor track data to be displayed and replayed on the map.
EPSG Coordinate Reference Systems / ISO 19111: All geometries are persisted in EPSG:4326 (WGS 84 geographic) and projected to EPSG:3857 (Web Mercator) for tile-based display, in accordance with the EPSG geodetic parameter registry.
AIS (ITU-R M.1371): Real-time vessel position feeds are ingested as Automatic Identification System messages, placing maritime entities on the live tracking layer alongside land and air assets.
