| Using Remote Sensing to Map Vegetation Density on a Reclaimed Surface Mine a simple NDVI-based technique is presented that estimated fractional vegetation cover on part of a reclaimed surface mine, producing less than 10 percent RMSE error when compared against 34 sample sites. Presented at the Incorporating Geospatial Technologies into SMCRA Business Processes Conference, March 25-27 2008, Atlanta Ga. |
| Well Location Accuracy Assessment, kanawha State Forest Two sources of Oil and Gas well locations in West Virgina-- the WVDEP Oracle database, and the Oil&Gas Information Service, are compared to a reference dataset of well locations in the Kanawha State Forest collected using differential GPS |
| Estimating Changes in Drainage Patterns on Areas Affected by Surface MiningElevation models created from LIDAR, photogrammetry, and hypsography were comparied to determine whether changes in surface drainage patterns could be identified after mining had occurred. Findings arising from a cooperative work agreement between the Office of Surface Mining's Charleston Field Office and the West Virginia Division of Environmental Protection |
| Development of a Mining Fill Inventory from Multi-Date Elevation Data details a change detection analysis is performed using two elevation grids representing different time periods with the objective of developing an inventory of mining cut/fill activity for a nine-county area of Southern West Virginia. Presented at the Advanced Integration of Geospatial Technologies in Mining and Reclamationi Conference, December 7-9, 2004, Atlanta Ga. |
| Automated Detection of Valley Fills from Multi-Date Elevation Data A county-wide LIDAR dataset, and historical contour elevation data, is used to automatically deliniate mining fills |
| An Assessment of LIDAR Data Quality LIDAR point data is compared with a large database of survey points for three watersheds in southern West Virginia |
| Extent of Mining Activity in Eight West Wirginia Watersheds Characterization of surface mining expansion from 1990-94 and 1994-98 |
