Introduction

Hydrodata is a large GPFS file share located at Princeton that contains a large number of hydrology related data files. The files in hydrodata are indexed by a data catalog.

The index is provided to allow code that needs to read information from /hydrodata to access the information without hard coding absolute path names to the files. This index makes it easier for people and code to locate files and understand the purpose of the files.

There is a python module to help programs get metadata and file paths from the data catalog.
