  • REMOTE SENSING AND ENVIRONMENTAL STUDIES
  • MAP REPRODUCTION
  • ACCURACY STANDARDS
  • DATUMS AND DATUM
  • TRANSFORMATIONS
  • GIS AND HYDROLOGIC MODELING
  • EMERGENCY MANAGEMENT SYSTEMS
  • AUTOMATED ENGINEERING

Recent research includes the following:

Remote Sensing/GIS Research
  • "MEASURING THE IMPACT OF TRANSIT INVESTMENT ON LAND VALUE USING SATELLITE REMOTE SENSING TECHNOLOGY", remote sensing, GIS, and econometric modeling research project was performed under the direction of Dr. Bishwa Acharya for the United States Department of Transportation, SBIR program. The Phase I study findings recommended for Phase II studies and the Phase II proposal has been submitted for funding.
Digital Photogrammetry Research
  • "Optimizing Photogrammetric Operations at GDOT", a digital photogrammetric research project was performed under the direction of Dr. Bishwa Acharya for the United States Federal Highway Administration and the Georgia Department of Transportation through the University of Georgia. The study findings were published in the ASCE Journal as, "Digital Terrain Model (DTM): Extraction & Accuracy Assessment" (PWE-Acharya & Chaturvedi). Subsequent research with digital photogrammetry was performed in 1999. Conclusions of the second study found digital photogrammetry accuracies to be superior to conventional analytical photogrammetry ( relative to DTM collection). Findings will appear in the proceedings of the ISPRS 2000 Congress as, "Accuracy Assessment of DTM Data: A Cost Effective Approach for a Large Scale Digital Mapping Project", Acharya, et al.
  • A white paper report on optimization of present-day photogrammetric techniques was performed in anticipation of the ISPRS 2000 Congress. Findings will be published as part of the proceedings (PWE: Acharya, et al)
GPS Research
  • A research was performed on geoid undulation using terrestrial and GRACE satellite gravity data towards height modernization. The research was funded by NASA.
  • A white paper was prepared analyzing the consequences of not having High Accuracy Reference Networks in Africa, Asia and South America. Conclusions will appear in the proceedings of the ISPRS Congress 2000.
  • Research was done on geoid modeling. This paper was published in GPS Navigation.
  • Research was done on GPS planning. This paper was published in the ACSM Journal of Surveying and LIS.
