InterMAP

mazeLocAlert allows a command vehicle in an emergency response scenario to track colleagues’ movements in a GNSS denied environment e.g. inside a building. The command vehicle can now see the position of their colleagues overlaid on to satellite imagery. While LocAlert tracks movement through the building it does not provide any information on the internal structure/layout of the building and it is not possible to determine if two colleagues are in the same room.

InterMAP extends LocAlert’s capabilities to incorporate spatial mapping, positional and locational awareness in urban, confined or indoor locations.

CONSENS, the technology used to build LocAlert, includes data communications capabilities as well as ranging. MapAlert uses CONSENS to transmit indoor spatial data to the command centre.

InterMAP incorporates sensors that calculate the distance between the tracked person and obstructions such as walls & pillars in their vicinity. This data is then relayed back to the command vehicle where the data is interpreted and translated in to a two dimensional map that shows the internal layout of the building.

The detail of the map will evolve as the tracked person moves around the building. This is similar to a computerised role playing game where at the start of a level the player’s map is empty but as they move around the level the map becomes more detailed.

The command vehicle receives data from more than one source and combines this in to a single map. This allows multiple teams to enter the building from different locations allowing the complete map to be captured and shared as quickly as possible. As with LocAlert the map is overlaid on to satellite imagery showing the internal layout of the building and the location of soldiers/first responders within that map.
