• Ron Cramer

  Mr. Cramer has more than two decades of experience in GIS and currently serves as the President of DDTI. Prior to DDTI, while with the Lietz Company (n.k.a. Sokkia), Mr. Cramer participated in product development of the company's SDR electronic data recording system and associated mapping software. He also developed an objective-based training program and managed a total of 35 distributors of surveying equipment while providing extensive training and support to federal, state, city/county government agencies, universities, and private industry throughout the United States.

  Under his guidance, DDTI was the first known company to use close range photogrammetry for 3-dimensional modeling of bridges in Ohio. In 1995, Mr. Cramer coordinated and performed the first digital photogrammetric bridge monitoring survey in the United States with Imetric International of Courgenay, Switzerland. He has written articles that have appeared in: The Ohio Engineer, Roads & Bridges, Illinois Engineer, Michigan Engineer, P.O.B. and Photo Electronic Imaging.

  Mr. Cramer is actively involved in intelligent transportation systems and was nominated and appointed to the ITS Mid-America Executive Committee for the years 1997 to 2003. He has been a guest speaker at numerous conferences discussing topics related to GIS, emergency response location mapping, and transportation engineering. Mr. Cramer was the last Conference Chair of URISA's Street Smart & Address Savvy Conference, which is now known as the Geospatial Integration for Public Safety Conference. Mr. Cramer is a member of the Urban and Regional Information Systems Association (URISA), and the National Emergency Number Association (NENA) and has affiliations with numerous organizations.

• Mark Wilcoxen

  Mr. Wilcoxen is currently a Partner and Corporate Secretary for DDTI, with extensive experience (over 15 years) in GPS collection and processing techniques. These techniques include both kinematic and static processing and collection. In addition, he has experience with the integration of auxiliary sensors with GPS and the combined data reduction methodologies.

  In addition, he has lead the research for the development of robust and spatial statistical methods for use in the geocoding of addresses for DDTI and the trajectory computation of the vehicles used for collecting address and road centerline data. Currently, he oversees the production processes for the spatial database generation for DDTI.

• Gabor Blaho, Ph.D.

  Dr. Blaho is currently a Partner and Vice President at DDTI, with over two decades of experience in the design and development of computer controlled instrumentation, as well as in software development. He previously had spent three years developing a stereo image acquisition system for mobile mapping applications and developing software for mapping specific data processing. Over the last decade, Dr. Blaho has developed and refined the new DDTI data collection system that has been instrumental in advancing the State of Ohio's Location Based Response System.

  Dr. Blaho invented and implemented a novel ultrasonic slow-wave imaging system and participated in the development of optical pipeline corrosion for the Edison Welding Institute, Columbus, Ohio. He also designed and developed a high-resolution ultrasonic C-scan imaging system and an industrial ultrasonic flaw detector.
