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, GPS location and time to be captured and stored on the field unit. Other sensor data is combined with the observations and combined with GPS and time information. A mobile unit's location is tracked real time or post processed through wireless RF transmission of location information between the mobile unit and a central processing station. Real time position correction is provided by Differential GPS (DGPS). The captured data is electronically transferred to a central processing station for operator performed quality assurance and automatic population of the GIS database. The system provides the algorithms to automatically correlate the data to linear and point observations in the GIS database. The system algorithms provide for automatic correlation of field data with all other GIS database layers. Tools to generate predefined or user defined reports, Work orders and general data queries allow exploitation of the GIS database.

[ What is claimed is:] [1.]1. A method of combining captured location data with captured voice data by using a predefined reference grammar with a semantic relationship structure, said method comprising:constructing the predefined reference grammar for the voice data to be captured;incorporating the semantic relationship structure in the predefined reference grammar;capturing free speech stating verbal observations containing the voice data;time tagging each said captured free speech stating verbal observations to create a raw verbal observation;capturing the location data contemporaneously with each said captured free speech stating verbal observations;time tagging the captured location data; andusing the predefined reference grammar and the semantic relationship structure to enable the captured voice data in at least two raw verbal observations to be combined automatically with the captured location data into a single record in a geographic information system data base.
