Mission Statement YOUR OBJECTIVE YOUR REALITY THE SOLUTION Generate geospatial data from aerial imagery Long, complex and expensive process Correlator 3 D™ Sim. Active’s mission is to constantly develop and market cutting-edge technologies that simplify and enhance geospatial data production

Growing Challenges Expensive Not User-Friendly • Only 30% project costs for data acquisition, remaining 70% associated with production • Complex software tools Geospatial Data Production Skills and Knowledge Long Process • Highly-trained personnel required • Several months usually required for data delivery

Design Criterion: Keep it Simple! Competitor Product Example Correlator 3 D™

Sim. Active Positioning Raw Data • Images • GPS / IMU data Core Data • • DSM DTM Orthophotos 3 D Changes Correlator 3 D™ Higher-level Data • Mosaics • Polygonal 3 D models • Etc.

Correlator 3 D™ INPUT Aerial images (overlapping) • Color, panchromatic, infrared Orientation Parameters • Exterior: GPS/IMU data • Interior: focal length, pixel size, distortion parameters Coarse DEM • CDED, DTED, SRTM OUTPUT Refined ext. orientation Logiciel Correlator 3 D DSM DTM Orthophotos 3 D Changes

Correlator 3 D™ Modules Exterior Orientation Refinement DSM Generation DTM Extraction Orthorectification 3 D Change Detection

Workflow Prepare Input Data 1 • Camera calibration (ASCII file) • Exterior orientation (ASCII file) • Selection of a coarse DEM • Specification of output characteristics Correlator 3 D™ – Automatic Processing 2 • Images are processed individually or pair-by-pair • No human intervention required • Runs on standard PC with 3 D graphics card Visualize / use data 3 • Data produced in standard formats

Example #1 – Urban Area Ortho DSM@@20 cm DTM 1 m

Example #2 – Rural Area DTM DSM@ @20 cm 1 m Ortho

Example #3 – New Building Imagery @ 40 cm (Jul. 2006) Imagery @ 5 cm (Oct. 2000) Detected Changes DSM @ 3 m DSM @ 1 m

Example #4 – Demolished Building Imagery @ 40 cm (Jul. 2006) Imagery @ 5 cm (Oct. 2000) Detected Changes DSM @ 3 m DSM @ 1 m

Processing Time & Output Quality ¨ Statistics for 250 large format images (100 MP) at 20 cm covering 400 km 2 Task Processing Time Data Quality Preparation 10 min EO Refinement 30 min 20 cm H. Accuracy DSM Generation 250 x 1 min. /image = 250 min 1 m H. Resolution / 20 cm V. Accuracy DTM Extraction 20 min 1 m H. Resolution / 20 cm V. Accuracy Orthorectification 250 x 1 min. /image = 250 min 20 cm H. Accuracy Total 9 hours

Benefits in a Nutshell FASTER. . . • Up to 60 times faster than currently available tools • Data production can be performed in parallel on multiple machines • Software designed to quickly process thousands of images EASIER… • Minimal software and data manipulation requirements • Highly-trained personnel are no longer required, virtually no parameters to set • Easy integration into any third-party workflow BETTER. . . • Better geospatial data at the fraction of the cost • Uses advanced computer vision algorithms • Produced data are ready-to-use • Cost-effective alternative to LIDAR data
