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.
