Principal Types of Data in the PSU ESSC Database

The keywords listed below define the main categories of data currently in the database. Some categories have subcategories; for example, DEM directories may contain subdirectories at different resolutions.

The list of available data types for a given geographic region which is returned by a database search normally gives the full name for each data type rather than the keyword. The names of the actual datasets and of data subcategories, on the other hand, normally incorporate only the keyword.
