The National Snow and Ice Data Center (NSIDC) supports research into our world's frozen realms: the snow, ice, glaciers, frozen ground, and climate interactions that make up Earth's cryosphere. NSIDC manages and distributes scientific data, creates tools for data access, supports data users, performs scientific research, and educates the public about the cryosphere.

"Google has a new desktop tool called Google Refine to help with cleaning up messy datasets, transforming them, and augmenting them with web-based data services. I could see this tool being used throughout the Lab in many areas: on field data, preparing science datasets for analysis, even run-of-the-mill business data manipulation. If you ever find yourself using a text editor or Excel to manipulate data, you might find this tool useful. Note that it comes in somewhat unusual packaging, because after downloading and installing the tool on your machine, you interact with it via a web browser. The link above has several videos that demonstrate its utility." (Paul Allen)

"What is the Earth Exploration Toolbook? The Earth Exploration Toolbook is a collection of computer-based Earth science activities. Each activity, or chapter, introduces one or more data sets and an analysis tool that enables users to explore some aspect of the Earth system. Step-by-step instructions in each chapter walk users through an example - a case study in which they access data and use analysis tools to explore issues or concepts in Earth system science. In the course of completing a chapter, users produce and analyze maps, graphs, images, or other data products. The ultimate goal of each activity is to build user's skills and confidence so they can use data to conduct their own investigations of the Earth system."

"The OpenHeatMap site lets you create heat maps and choropleths from uploaded spreadsheet data (CSV format), or Google Docs Spreadsheet data (which makes it continuously updatable). It supports location coding by latitude/longitude coordinates, or by a large number of name/code attributes (e.g. address, FIPS code, zip code, state, province, country). And as a bonus, you can also have time as a variable, letting you create animated heatmaps or choropleths."

"CUGIR is an active online repository in the National Spatial Data Clearinghouse program. CUGIR provides geospatial data and metadata for New York State, with special emphasis on those natural features relevant to agriculture, ecology, natural resources, and human-environment interactions."

NOAA created this site to help educators find data resources ranging from student-friendly to raw real-time and historical data on topics ranging from hurricanes to Great Lakes science. The Visualization Laboratory has an image of the day that relates to a current meteorological event and it contains images and videos pertaining to current and historical severe weather events, disasters, hurricanes, climate, oceans, atmosphere, and remote sensing.

Earthquakes, tsunamis, floods, wildfires... "IcEarth offers an innovative approach for the use of satellite and airborne remotely sensed data and current and historical aerial photography combined with an in-depth explanation of what the data represents. Images, technical application, and topical themes support environmental science, earth science, and geographic inquiry by complementing educators existing curriculum."

"virtual data repository", providing a gateway to information from a variety of data centers and web sites, including those of federal and state governments, academia, private industry, and wind energy-related trade associations. The tools and interfaces on this site have been designed to facilitate the discovery, visualization, subsetting, and downloading of this information.

"The "classic" (at least if you're a GIS geek) 1967 short feature "Data for Decision" produced by the National Film Board of Canada describes the development of the Canada Geographic Information System (CGIS)."

The Topographic and Bathymetric Data Inventory displays the best-available topographic and bathymetric data for the United States.

"Ocean Tracks provides access to authentic data collected by migrating marine animals, drifting buoys, and satellites, along with tools that allow you to display and analyze these data to investigate current and important scientific questions about animal interactions with the ocean environment. "

Multimedia, lessons, data, and background information about the Great Lakes. Includes a "Listen to the Lake" podcast and several webcams. Lessons to download relate to watershed land use, fish life cycles, invasive species, human population, and others.

ohhh. I've used this website often but didn't realize they offered spatial data. Can't wait to try
