Introduction to ERDDAP¶
The goal of ERDDAP is to simplify the access and use of scientific data. ERDDAP acts as a central repository for gridded and tabular data from multiple sources, both local and remote. This allows a user to have access to data in one place, while having the added capabilities of subsetting, graphing, mapping and downloading the data in a variety of commonly used formats.
