A data collection and automatic database population system which combines global positioning system (GPS), speech recognition software, radio frequency (RF) communications, and geographic information system (GIS) to allow rapid capture of field data, asset tracking, and automatic transfer of the data to a GIS database. A pre-defined grammar allows observations to be continuously captured along with GPS location and time, and stored on the field mobile unit. A mobile unit's location is tracked in real time or post processed through wireless RF transmission of location information between the mobile unit and a central processing station. The captured data is electronically transferred to a central processing station for quality assurance and automatic population of the GIS database. The system provides for automatic correlation of field data with other GIS database layers. Tools to generate predefined or user defined reports, work orders, and general data queries allow exploitation of the GIS database.

The temperature control simulation method according to claim 4, wherein said transfer function means is calculated from a stepped response of each of said plurality of heaters comprising: measuring a temperature output of said heating furnace when a stepped input is applied to each of said plurality of heaters; measuring a temperature output of each of said heaters when a constant input is applied to each of said heaters at the same point of time as when said stepped input is applied to calculate a change over time of said temperature output of each of said heaters; and calculating said transfer function means based on said temperature output response value which is subtracted by said change over time of said temperature output of each of said heaters to cancel variations in a power supply which supplies electric power to said heaters. 6. The temperature control simulation method according to claim 1, wherein said transfer function means comprises a plurality of transfer functions corresponding to a plurality of different temperature zones, and wherein said plurality of transfer functions are switched to select an appropriate one corresponding to each of said plurality of temperature zones.
