PE&RS April 2000

Cover Image

This month’s cover shows MODIS/ASTER (MASTER) airborne data of Grapevine Springs, Death Valley National Park, California and Nevada. The data were processed by Analytical Imaging and Geophysics (AIG) using the ENVI® image processing system.

MASTER is an airborne simulator with 50 spectral bands, operated by NASA Ames for investigations utilizing MODIS and ASTER on the NASA Terra satellite. The left image is a false-color composite of MASTER data, bands 9, 5, and 3 (0.87, 0.67, and 0.54 mm), RGB. North is left. Spatial resolution is 4.3 meters. The right image shows a MASTER long-wave infrared image utilizing bands 47, 44, and 42 (10.54, 9.95, and 8.21 mm), RGB.

AIG uses these images for geologic mapping and comparing fossil and active geothermal springs characteristics. The bright areas in the center of the left image are springs deposits. In the right image, green represents tufa springs and other carbonate deposits. Quartizites appear bright red, while low silica volcanics appear blue and purple.

393 Accurate Orientation for Airborne Mapping Systems
Jan Skaloud and Klaus-Peter Schwarz

Filtering methods in INS/GPS airborne attitude determination are analyzed.  

403 Contributions of Differential GPS and GLONASS Observations to Point Accuracy  under Forest Canopies
Eric Næsset, Trygve Bjerk, Ola Øvstedal, and   Lorentz H. Ryan

A regression model classified correctly 81.5 percent of the processed solutions.  

409 Accuracy Assessment of Wetland Boundary Delineation Using Aerial Photography and Digital Orthophotography
Jeffrey Barrette, Peter August, and Francis Golet

The positional accuracy of forested wetland boundaries delineated from large-scale digital orthophotography is compared to boundaries derived from aerial photography.  

417 Detecting Ice-Sheet Topography with AVHRR, RESURS-01, and Landsat TM  Imagery
Robert Bindschadler and Patricia Vornberger

AVHRR had the best radiometric resolution but poorer spatial resolution, RESURS-01 had higher noise and poorer radiometric resolution, and Landsat TM achieved a radiometric resolution only half that of AVHRR but had a much higher spatial resolution.  

423 Predicting the Distribution of Eurasian Badger (Meles meles) Setts over an Urbanized Landscape: A GIS Approach
Amanda Wright, Alan H. Fielding, and   C. Philip Wheater

Within a heavily urbanized county with a small badger population, a predictive model was able to identify topographic and land-cover characteristics associated with main sett locations.  

429 Multispectral Satellite Image and Ancillary Data Integration for Geological Classification
Evaristo Ricchetti
Comparisons of different procedures for geological classification of multispectral imagery demonstrate the improvement in accuracy of results achieved using terrain information from a digital terrain model (DTM).  

437 Integrating Landsat, Geologic, and Airborne Gamma Ray Data as an Aid to Surficial Geology Mapping and Mineral Exploration in the Manitouwadge Area, Ontario
I.M. Kettles, A.N. Rencz, and S.D. Bauke

The predictive surficial geology map generated from the Landsat data, when compared with the published surficial geology map, had an overall pixel-by-pixel accuracy of 46 percent.
