Tracking a person in a building can be performed by obtaining a building layout with respect to a surrounding geography and tracking movement of the person using a monitoring device carried by the person. A correction angle can be calculated to normalize tracked movement of the person with respect to a skew angle of the building layout. The correction angle can be applied to the tracked movement of the person or the building layout.

Building perpendicularity testing and adjustment

Variable step tracking is described in which a monitoring station is operable to receive data signals representative of step movement of an asset as detected by a monitoring device carried by the asset. A database stores a step length of the asset. A step length modification module modifies the step length based on at least one of energy, asset orientation, direction, and frequency associated with the step movement. An asset position is estimated with respect to a known location based on cumulative step lengths.

Variable step tracking

Generating a computer model to display a position of a person in a defined location is disclosed. A method includes the operation of selecting a substantially overhead image of a defined location having spatial coordinates. A perimeter of the defined location is marked using a graphical user interface. The marked perimeter is related to the spatial coordinates of the defined location. A computer model of the defined location is generated based on the marked perimeter. Multiple levels can be added to the computer model. Spatial coordinates of the person can be determined. The position of the person can be displayed relative to the computer model of the defined location based on the spatial coordinates of the person relative to the spatial coordinates of the defined location.
