What is geoWhat is geo--Enabled Modeling and Enabled Modeling and SimulationSimulation

Running M&S applications on operationalgeospatial data

Improved interoperability between C4ISR and M&SUsing actionable geospatial information for higher level behaviors

Improved computer decision makingUsing CJMTK (GIS) enterprise services for data and information that support both C2 and M&S applications

True train as you fight capabilityEnabler for mission planning, missionrehearsal, and predictive situation awareness


Challenges geoChallenges geo--Enabled M&S AddressesEnabled M&S Addresses

Data commonality, availability and accessMove from simulation specific terrain data to common geospatial information

Simulation behaviorsDevelop realistic behaviors that are based on doctrine using geospatial information that is also based on doctrine (TSOs)Move up from reasoning at the dirt level to reasoning at the operational levelAssociation of battlespace entities with actionable geospatial information

Interoperability StandardsGeospatial - GML, geo-BMLSimulation – HLA, DIS, TENA, MSDLCommand and control – BML, JC3IEDM

Current Geospatial Data ApproachCurrent Geospatial Data ApproachC4ISR systems and M&S systems use different tools and formats for generating and storing geospatial information

C4ISR – CJMTK, GIS, NGA dataM&S – Specialized run time formats for each application

OOS – OTFJSAF – CTDBOthers – OpenFlight, MrTDB, MÄK GDB, …

No single geospatial representation supports both domainsEven within just simulation domain, no common representation of geospatial information (not even data)


Problems With Current Geospatial Problems With Current Geospatial ApproachApproach

Expensive and time consuming to produce M&S terrain databasesCorrelation between M&S terrain data difficultCan not easily share geospatial information between C4ISR and M&S

Makes mission planning or embedded training more difficultHarder to maintain geospatial information as it changes

A common geospatial approach that can generate data (and information) with a single set of tools and share it across applications would help alleviate these problems

Actionable Geospatial InformationActionable Geospatial Information

Today, M&S systems access static geospatial data, but must generate actionable geospatial information during run time

Uses valuable compute resources which limits higher level behaviorsNo commonality of generated information between different M&S systems

Examples of actionable geospatial informationTactical spatial objectsRoute generation based on factors other than shortest pathSemantic information

Directional concealment, ridge lines, etc.


Actionable Geospatial InformationActionable Geospatial Information

Use GIS and terrain analysis capabilities of CJMTK to generate it

Battlefield Terrain Reasoning and AwarenessOther terrain reasoning models using Spatial Analyst and 3D Analyst

Use geo-BML to distribute with orders and reports to / from M&S

In context of mission and taskAllows heterogeneous simulations to have more common behaviors

6


Composable BehaviorsComposable Behaviors

Actionable geospatial information with BML enables composable behaviors

Start with primitive behaviors based on physical characteristics of entities

Move, shoot, communicateBuild higher level behaviors based on mission, task, situation awareness, spatial awareness

Coordinated tasks in time and spaceSubordinate tasking in M&S

Don’t have to use valuable M&S cycles to generate geospatial information

GeoprocessingGeoprocessingExpands linear features by their width attribute to create area features.Expands point features by their width and length attributes to create area features.Building point features are combined with the area building features into a single layer.Creates a unified soil type layer and stores pointers to it directly in the TIN.Extrudes buildings by their height attributes to create 3D multipatch features.Adds building area features to the TIN layer, with references to the 3D multipatchfeatures.
