Locations for nine species of large constrictors, from published sources, along with monthly precipitation and average monthly temperature for those locations. Shapefiles for each snake species studied.
GPS measurements made since 1996 seem to show this earthquake-prone area slowing down. Is it time to relax? Scientists who studied these data in detail say no, and this fact sheet explains why.
Describes the analytical process by which spatial scientific information contributes to forecasts and models in support of regional and local decision-making.
Website with links to USGS hydrologic, geohydrologic, soil, and geologic projects in Missouri using geographic information systems (GIS) technology with digital datasets of images, models, and maps produced by the projects to view.
