It provides the participants with a good understanding of the concept of direct georeferencing (directly measuring the exterior orientation parameters of each single image using GPS-aided Inertial data). In principal, this concept allows the elimination of the aerial triangulation and ground control from the mapping process except for quality assurance purposes. The workshop design will cover several examples from real applications using different sensors and applications, and mapping products. The workshop will emphasize the following topics: I. Concepts of Direct Georeferencing A. Basic concept of direct georeferencing (Sensor Integration) B. Calibration aspects in direct georeferencing systems C. Mission Planning and its implications D. Quality assurance and quality control (real-time and postmission) E. Using direct georeferencing systems for aided Automatic Aerial Triangulation II.

Tangential Coordinate Frame Implementation for Direct Georeferencing III. Land-Based Mobile Mapping Systems A. Direct Georeferencing Concept for Land-based Mobile Mapping applications B. Current Technology (sensor resolution, data rate, and operational parameters) C. Data acquisition and Synchronization D. Multi-Sensor System Calibration E. Integration and data fusion. F. Data flow optimization. G. Quality control (in real-time and Post-mission). 17

Airborne GPS-controlled Aerial-Triangulation: Theory and Practical Concepts Room: Wilson A 8:30 am - 5:30 pm PDH Hours: 8 CEUs: .8 Dr. Qassim A. Abdullah, Senior Mapping Scientist, EarthData Technologies, LLC Hagerstown, Maryland Dr. Riadh Munjy, Professor of Surveying and Civil Engineering at California State University, Fresno Dr. Mushtaq Hussain, Professor of Surveying and Civil Engineering at California State University, Fresno The workshop will provide the participants with a good understanding of the new concept of controlling the camera position with a differential carrier phase GPS receiver to dramatically reduce the amount of ground control required for conventional aerial triangulation. The workshop will also present design concepts, practical results, and strengths and shortcomings of the technology. Participants, at the end of the workshop, are expected to have enough understanding to enable them to evaluate, design, and/or execute an airborne GPS-controlled aerial-triangulation mission. I. What is airborne GPS-controlled aerial-triangulation and how does it differ from traditional aerial-triangulation? II. Fundamentals of the airborne GPS system. III. The status of airborne GPS-controlled aerial-triangulation in production today. IV. Functional system design and requirements for an airborne GPS photogrammetric system. V.

Performance, Accuracy, and Economics of Imaging Sensors, Lidar, and Advanced Acquisition Technologies for Surface Data Generation Room: Wilson B 8:30 am - 5:30 pm PDH Hours: 8 CEUs: .8 Mike Renslow, Vice President - Spencer B. Gross, Inc. Dr. Bryan Mercer, Chief Scientist -Intermap Technologies Corp. There are a number of existing, as well as planned, imaging and other sensing systems that are specifically designed for surface data generation. These include high-resolution satellite imagery, interferometric SAR, Lidar, as well as others. Surface extraction based on softcopy photogrammetric technology requires digital imagery as a primary input. Although the source data is usually in the form of scanned aerial photography, the other acquisition technologies need to be examined in terms of higher accuracy as well as cost effectiveness. This workshop tutorial aims at providing a comprehensive understanding of the technology, accuracy, and performance of various imagery alternatives available for surface data generation. In addition, the tutorial will examine the economic viability and cost effectiveness of such data against film-based photography for surface data generation. These alternatives are such as Lidar, high-resolution satellite imagery, in-house scanning of aerial photography, and outsourcing scanning needs. The analysis is applied with a specific set of variables, assumptions, and a forecasting risk that is within acceptable limits. I. Background on Image Acquisition Methods II. DTM Data Generation Techniques III. High Resolution Satellite Imagery IV. Lidar, SAR, and Other Technologies V. Support Technologies: GPS, INS, IMU VI. Inter-comparison and Accuracy Evaluation VII. Cost Effectiveness and Scanning of Aerial Photography VIII. Outlook Saturday • Half-Day Morning Workshops ASPRS WS #7.

The workshop will give an overview on the use of digital photogrammetry as an aid to architectural conservation work as typically carried out in the United Kingdom. All of the project data to be shown will have been produced using either the LH Systems SOCET SET or ISM system software and it is hoped to have a variety of digital photogrammetric workstations available for ‘hands on’ demonstrations of the various projects.
