Spatial asset management system and method
First Claim
1. A method for performing field data collection, the method comprising:
- (a) capturing a verbal observation as audio data;
(b) time-stamping said audio data;
(c) capturing location data contemporaneously with said verbal observation with a location receiver device;
(d) time-stamping said location data;
(e) interpreting said audio data using semantic information stored in a reference grammar;
(f) creating a recognized text data record from said interpreted audio data;
(g) merging said location data and said recognized text data record to form a time-based observation data object; and
(h) converting said location data into a time-based track data object.

Abstract
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.

25. An apparatus for performing field data collection, the apparatus comprising:
-
a mobile computer, said mobile computer comprising, a central processing unit;
a system sound card connectable to said central processing unit;
a microphone in communication with said system sound card, wherein said microphone and said system sound card cooperatively capture a verbal observation as audio data;
a central processing unit clock connectable to said central processing unit; and
a memory connectable to said central processing unit, wherein said central processing unit loads into said memory a reference grammar containing semantic information; and
a location receiver device in communication with said mobile computer for capturing location data contemporaneously with said verbal observation;
wherein said central processing unit clock time-stamps said captured audio data and time-stamps said location data received from said location receiver device;
and further wherein said central processing unit;
interprets said audio data using said reference grammar containing semantic information;
creates a recognized text data record;
merges said location data and said recognized text data record to form a time-based observation data object; and
converts said location data into a time-based track data object. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
