Remote sensing applications for paleobotanical exploration.

Among the challenges of conducting field research in remote regions is the logistics of how to most efficiently travel to known sites, and recognizing and trekking to the most promising sites with yet undiscovered specimens. The purpose of this project was to determine the feasibility of using remote sensing data to evaluate potential fossil sites and to plan paleobotanical field research in western Madagascar. Several known sites from published reports, and first-hand field and museum data were located using available geospatial data. All possible current roadways and access points to sites were found using satellite data and enhanced to create maps for future field research. Data will be presented to illustrate the resolution of these maps. These regions were then examined using remote sensing processes to detect geologic signatures in exposures that indicate potentially favorable sites. The ENVI ratio algorithm was used to locate specific exposures. Ratios that were used in the algorithm were 5/7 for clay, 3/2 for iron-oxide and 4/3 for vegetation among others. Spectral data was processed to find promising fossil sites for future field research. In summary, existing satellite data was applied to assist in the logistics and preparation of paleobotanical exploration within remote regions. These results suggest that remote sensing techniques would be beneficial for other paleontological research.
