44 Evaluation of Test Flights Testee s do not know the configuration of the targets. They do not know the temperature of the targets. False targets are included. Information collected is to be delivered by hand or by ftp to awaiting ground crew for evaluation. Measurement criteria and methods were developed and accepted prior to testing. Measurement, + or for detecting the heat source. Measurement of the spatial precision of those heat sources found. Findings are summarized into a publishable report. The analysis included: Comparison of set targets to targets identified Comparison of the Vendor target points to ground surveyed points Quality of projection in 10TM and UTM Response time from acquisition to delivery in minutes Temperature record for each target during evaluation Review of Gap Light Transmission indices (GLT) and forest cover photo Acquisition time and number of flight passes required April 24-28, 2006 RS

45 FOREST PROTECTION BIRD DOG TRIALS April 24-28, 2006 RS

46 GRID TEST FINDINGS Test Site represents a real world scenario. Process has been refined and is repeatable. Tests are run through a third body, with no biases. Believe that the test represents a true measure of the Testee s capabilites as they would relate to our TIR information needs. Hope to use site for all thermal testing, including contract rotary wing services, Out of province thermal testing and new sensors. April 24-28, 2006 RS

50 EXPANDED THERMAL INFRARED PRIMER April 24-28, 2006 RS

51 New Hand-Held Units: An evaluation is currently being completed to assess the correct Hand-held thermal units for our operations, including the province of British Columbia. On-board Rotary Wing Mapping An exercise completed last year showed that at least 1 hour of air time can be reduced in rotary wing thermal operations, if the aircraft Is equipped with map production capabilities. Wireless Communications Testing will continue to prove out the capability of delivering the thermal information to pda s and such at the fireline, reducing burning time and increasing effectiveness of the information. April 24-28, 2006 RS

52 More Effective Scanning Processes As part of this year s fixed wing contract, we will be looking to monitor The efficiency of the various scanning sensors and resolution options To allow for better prescription of services. Fixed Thermal Scanning Currently testing a fixed base application of a thermal scanning application that can sense changes in imagery scanned along the horizon and can triangulate position of smoke. Collaboration with Canadian and US Agencies Currently working with the western Canadian provinces to provide a more coordinated initiative. In addition, would like to continue to work with the RSAC people and other US thermal operations to further the science and application of Thermal IR. April 24-28, 2006 RS
