Deformation associated with the 1997 eruption of Okmok volcano, Alaska Deformation associated with the 1997 eruption of Okmok volcano, Alaska
Okmok volcano, located on Umnak Island in the Aleutian chain, Alaska, is the most eruptive caldera system in North America in historic time. Its most recent eruption occurred in 1997. Synthetic aperture radar interferometry shows deflation of the caldera center of up to 140 cm during this time, preceded and followed by inflation of smaller magnitude. The main part of the observed...

Transient stress-coupling between the 1992 Landers and 1999 Hector Mine, California, earthquakes Transient stress-coupling between the 1992 Landers and 1999 Hector Mine, California, earthquakes
A three-dimensional finite-element model (FEM) of the Mojave block region in southern California is constructed to investigate transient stress-coupling between the 1992 Landers and 1999 Hector Mine earthquakes. The FEM simulates a poroelastic upper-crust layer coupled to a viscoelastic lower-crust layer, which is decoupled from the upper mantle. FEM predictions of the transient...

Impacts of patch size and land-cover heterogeneity on thematic image classification accuracy Impacts of patch size and land-cover heterogeneity on thematic image classification accuracy
Landscape chamcteristics such as small patch size and landcover heterogeneity have been hypothesized to increase the likelihood of mis-classifying pixels during thematic image classification. However, there has been a lack of empirical evidence to support these hypotheses. This study utilizes data gathered as part of the accuracy assessment of the 1992 National Land Cover Data (NLCD) set...

Geographic techniques and recent applications of remote sensing to landscape-water quality studies Geographic techniques and recent applications of remote sensing to landscape-water quality studies
This article overviews recent advances in studies of landscape-water quality relationships using remote sensing techniques. With the increasing feasibility of using remotely-sensed data, landscape-water quality studies can now be more easily performed on regional, multi-state scales. The traditional method of relating land use and land cover to water quality has been extended to include...

The national elevation data set The national elevation data set
The NED is a seamless raster dataset from the USGS that fulfills many of the concepts of framework geospatial data as envisioned for the NSDI, allowing users to focus on analysis rather than data preparation. It is regularly maintained and updated, and it provides basic elevation data for many GIS applications. The NED is one of several seamless datasets that the USGS is making available...

Interferometric synthetic aperture radar studies of Alaska volcanoes Interferometric synthetic aperture radar studies of Alaska volcanoes
Interferometric synthetic aperture radar (InSAR) imaging is a recently developed geodetic technique capable of measuring ground-surface deformation with centimeter to subcentimeter vertical precision and spatial resolution of tens-of-meter over a relatively large region (/spl sim/10/sup 4/ km/sup 2/). The spatial distribution of surface deformation data, derived from InSAR images...

Achieving sub-pixel geolocation accuracy in support of MODIS land science Achieving sub-pixel geolocation accuracy in support of MODIS land science
The Moderate Resolution Imaging Spectroradiometer (MODIS) was launched in December 1999 on the polar orbiting Terra spacecraft and since February 2000 has been acquiring daily global data in 36 spectral bands—29 with 1 km, five with 500 m, and two with 250 m nadir pixel dimensions. The Terra satellite has on-board exterior orientation (position and attitude) measurement systems designed...

Magmatic activity beneath the quiescent Three Sisters volcanic center, central Oregon Cascade Range, USA Magmatic activity beneath the quiescent Three Sisters volcanic center, central Oregon Cascade Range, USA
Images from satellite interferometric synthetic aperture radar (InSAR) reveal uplift of a broad ~10 km by 20 km area in the Three Sisters volcanic center of the central Oregon Cascade Range, ~130 km south of Mt. St. Helens. The last eruption in the volcanic center occurred ~1500 years ago. Multiple satellite images from 1992 through 2000 indicate that most if not all of ~100 mm of...

Extracting low‐resolution river networks from high‐resolution digital elevation models Extracting low‐resolution river networks from high‐resolution digital elevation models
Including a global river network in the land component of global climate models (GCMs) is necessary in order to provide a more complete representation of the hydrologic cycle. The process of creating these networks is called river network upscaling and consists of lowering the resolution of already available fine networks to make them compatible with GCMs. Fine‐resolution river networks...

Satellite mapping of surface biophysical parameters at the biome scale over the North American grasslands: A case study Satellite mapping of surface biophysical parameters at the biome scale over the North American grasslands: A case study
Quantification of biophysical parameters is needed by terrestrial process modeling and other applications. A study testing the role of multispectral data for monitoring biophysical parameters was conducted over a network of grassland field sites in the Great Plains of North America. Grassland biophysical parameters [leaf area index (LAI), fraction of absorbed photosynthetically active...
