Contra Costa County Watershed Atlas

Contra Costa County watershed map

The Contra Costa County Community Development Department has made the Contra Costa County Watershed Atlas available in both print and online as a pdf. From the publication's site: "The Contra Costa County Watershed Atlas is a large format, full color, 150-page book of maps, statistics and text about the 28 major watersheds in the County. Though focused on the state of natural ecosystems on the watershed scale, the Atlas also provides information about the human community and the county as and eco-region."

"Additionally, the Atlas includes the complete CCWF Creek and Wetland Enhancement Project Database, samples of GPS data collected by community groups on creeks. Maps provided at a countywide scale include: watersheds, creeks, political boundaries (cities, spheres of influence and unincorporated communities), planned land use, demographic data, topography, hydrology, earthquake fault lines, flood plains, soils, aspect, slope, vegetative cover, temperature, rainfall, impervious surface, historical and current steelhead trout populations and color aerial photographs."

The atlas is available online and in print at the Water Resources Center Archives. Copies of the atlas are also available for purchase from the Contra Costa County Community Development Department.

Integrated Ocean Drilling Program core locations in Google Earth

Detail view of IODP hole locations on Google Earth

The Integrated Ocean Drilling Program (IODP) has made the location and scientific information about each of its core locations available in Google Earth. The KML file displays the precise location (latitude and longitude) of each core and gives scientific information including data about the hole, core sample, and links to related data. Additionally, users can download a broad range of data for each core location.

The data comes from "the Core Data from the Deep Sea Drilling Project Legs 1-96 CD-ROM produced in 2000 by the U.S. Department of Commerce, National Oceanic and Atmospheric Administration, National Environmental Satellite, Data, and Information Service, National Geophysical Data Center, and collocated World Data Center for Marine Geology and Geophysics, Boulder. Data were compiled in cooperation with the U.S. Science Support Program, the Joint Oceanographic Institutions, Inc., and the U.S. National Science Foundation."

The Google Earth layer also includes data from holes drilled as part of the Ocean Drilling Program (ODP) and the Deep Sea Drilling Project (DSDP).

Library patrons can access both Google Earth and Google Earth Pro at the Earth Sciences and Map Library.

Giovanni remote sensing tool

NASA Giovanni page

NASA has made a new remote sensing tool, Giovanni, available online. "Giovanni is a Web-based application developed by the GES DISC that provides a simple and intuitive way to visualize, analyze, and access vast amounts of Earth science remote sensing data without having to download the data. Giovanni is an acronym for the GES-DISC (Goddard Earth Sciences Data and Information Services Center) Interactive Online Visualization ANd aNalysis Infrastructure."

Giovanni is made available in four different categories of instances:

Each instance draws data from different sources that range from A-TRAIN to TRMM.

The Giovanni site provides a full users manual and information for users just starting out with the tool.

The National Map

Topo quad detail Orthophoto detail

The National Map, a part of the USGS National Geospatial Data Program, is a good resource for both digital maps and gis data for the United States. From the National Map site: "The National Map is a collaborative effort among the USGS and other Federal, State, and local partners to improve and deliver topographic information for the Nation. It has many uses ranging from recreation to scientific analysis to emergency response. The National Map is easily accessible for display on the Web, as products and services, and as downloadable data. The geographic information available from The National Map includes orthoimagery (aerial photographs), elevation, geographic names, hydrography, boundaries, transportation, structures, and land cover."

The National Map is currently accessible through four different frequently updated viewers:

The National Map Viewer is the face of The National Map and allows the user to interactively view The National Map data as a map, customize the view, and print maps.

The National Map Seamless Server enables a user to view and download many geospatial data layers, such as the National Elevation Dataset, the National Land Cover Dataset, high resolution orthoimagery, and other seamless data for the Nation.

The National Map Best Practices viewer
contains our most up-to-date vector data for transportation, structures, and governmental units data themes.

The National Map National Hydrography Dataset (NHD) viewer
contains our most up-to-date, full featured hydrography data.
