2010-08-27: Virtual Workshop WCS Implementation

Introduction

Who is this workshop for? Anyone interested in:

• Making their data more widely accessible
• Using standard tools and catalogs instead of custom-made
• Need help adding a standard interface to data

Participants in this workshop may have varied backgrounds on web services (from novice to expert). The varied experience will allow participants to form mentor relationships.

Problem: Data is distributed, in different formats and can't be accessed by common tools within the AQ Community

Solution: Create a standard interface to the data using OGC Web Coverage Service

• Data Access through OGC WCS Protocol

In-depth Details (programmers?)

Case studies of how Data Systems Implemented WCS:

• DataFed
• DLR
• Giovanni/NASA
• RSIG
• Airnow
• Univ. of New Mexico

How-To

Questions about WCS

What WCS questions/issues have you encountered? If you know the answer to these questions please respond below the question with ** and add your name.

Questions from Steve Ludewig, Sonoma Tech

• The WCS protocol – how can/should it be extended for air quality
• How should we handle different or even multiple parameter requests? (separate arguments? Lists as arguments?)
• Duration codes?
• Parameter occurrence codes (POC)?
• Time_Sequence: Ours currently is a single date/time -- should it accommodate a time range (performance is a concern)? What time standard? (UTC?)
• Use of an API key for authentication.
• Output (payload) formats
• Field naming
