Stopped by the USGS Seamless Server recently for the first time in a while, and noticed they’ve added a drop-down list titled “Available Interactive Maps”. Listed there are a fairly wide-ranging set of data resources they’re working on; some are mostly duplicates of the Seamless Server data but with a slightly-different focus, while others contain unique data.
ARMI: A data viewer and retriever for the USGS’s Amphibian Research and Monitoring Initiative, a program designed to study and hopefully slow down the recent drastic reductions in amphibian numbers. Data includes factors like pesticides, hydrography, climate/weather and more.
- Landsat data, including 6-band corrected imagery by 1:250K quads
- Aster Level 1A and 1B data
- SRTM 90-meter DEMs, with void filling
- German, Russian and USGS geology maps
- Full sets of Russian topographic maps, 1:50K and 1:200K
U.S.-Mexico Border Environmental Health Initiative: Interactive data viewer for “satellite imagery, orthoimagery and integrated geology, hydrology, transportation, geographical names, potential sources of contaminants, demographic data for population density, Nexrad daily weather, and boundary datasets”.
Drought Monitoring: Drought and vegetation index data for the United States.
Elevation Derivatives For National Applications (EDNA): Hydrological-oriented database (30-meter US resolution) with raster and vector data:
- Filled DEM
- Flow Accumulation
- Flow Direction
- Reach Catchment Seedpoints
- Reach Catchments
- Shaded Relief
- Synthetic Streamlines
Integrated Vegetation Mapping Viewer: NDVI (normalized differential vegetation index), Fire Potential, Percent of Average Seasonal Greenness, and more.
MRLC: Focused on the National Land Cover Database (2001 and 1992).
MOPEX: Focused on stream, watershed and hydrological data for the US.
