Polarhub is a service-oriented portal funded by the National Science Foundation aimed at improving accessibility and usability of polar science data. It includes features like a web crawler for deep web data extraction, multi-user support, and a portable client-server communication mechanism. The project aims to identify 40,000 OGC web services and enhance earth science data discovery.

- 1. PolarHub: A Global Hub for Geospatial Service Discovery Wenwen Li School of Geographical Sciences and Urban Planning Arizona State University EarthCube All Hands Meeting 06-25-2014
- 2. Building a Service-Oriented Polar CI Portal to Support Sustained Polar Sciences • Funded by National Science Foundation (NSF) • Objectives: – Objective 1: Establish a large-scale web crawler to improve the accessibility of Big Polar Data – Objective 2: Monitoring Data and Service Quality to Improve Portal Usability 2
- 3. PolarHub Features • Dig into the deep Web to extract data of interest; • Multi-task, multi-user, multi-thread support to the crawling tasks; • A pattern-matching based crawling algorithm; • A portable client-server communication mechanism for enhanced asynchronous processing
- 4. PolarHub • Target: – Identify 40k OGC web services; – Extend to support discovery of other type of earth science data; – Bridge with other existing crawling/CI portal systems
