In the menu bar at the top of the web site, you'll see "Datasets", "Collections", and "Projects".

• Datasets are individual datasets such as a shapefile or a Tagged Image File Format (TIFF) file. Note that these "files" are really groupings of files that contain one dataset. The dataset could be the boundaries for cities, centerlines of streams, or a digital elevation model (DEM) for Humboldt County. All the datasets in the system can be accessed through the Dataset pages.
• Collections are large datasets that have been broken up into smaller datasets to make it easier to download and work with them.
• Projects are datasets that are related through a common project. This could be historical datasets for Humboldt Bay or all the current datasets for the city of Eureka.
