ceda-di's Introduction

ceda-di

The ceda-di project is a suite of Python scripts and tools to extract JSON metadata from various scientific data formats, including:

  • ENVI BIL/BSQ
  • NetCDF
  • GeoTIFF (EXIF metadata)
  • HDF

The Python backend is designed to be run on a system with a large number of CPU cores. It extracts metadata from scientific data files and outputs it as platform-independent JSON documents.

This JSON metadata can then be stored in a NoSQL data store such as ElasticSearch. This repository contains some example applications of the toolkit, including an Ansible playbook to set up and configure an ElasticSearch cluster. This repo also contains a sample web interface that allows for real-time faceted search (including full-text, temporal, and geospatial facets) and live display of data files on a map.
