Dataset Attributes and the LTER IMC: A First Step

Issue: 
Fall 2010

Corinna Gries (NTL), Wade Sheldon (GCE), Karen Baker (CCE, PAL)

A virtual water cooler was held 1-2 Nov 2010 to initiate an LTER IMC process of discussing attribute labels and descriptions. Dataset attribute labels play an essential role in the discovery and integration of data as well as in preparation for mapping to ontologies. The lack of attribute standardization in LTER is being recognized as a major impediment to data discovery as well as to modeling efforts at sites and to cross site synthetic data analyses.

Writing the Connectivity Report

Issue: 
Winter 1990

We haven't seen each other since November. As members of the LTER Connectivity Team we were in New England then. A small band of undeterrable energy in pursuit of network information wherever it could be found. Sleeping in cars. Working in cars. Eating in bars. Sleeping in Motel 6's from Hell. Working in bars. Working in airports. Sleeping in airports. Despite the hectic schedule, the LTER Connectivity report was little more that a couple of pages of carefully pondered script hacked out in a hotel room late one night and an outline created while driving across Georgia.

Global Positioning Systems

The U.S.Department of Defense developed the Global Positioning System (GPS ) to provide accurate geopositional data for any point on the earth's surface. The GPS utilizes computers and a constellation of 21 NAVSTAR satellites (plus three spares) orbiting at an altitude of 10,900 nautical miles to triangulate positions on earth. GPS's differ in spatial resolution, cost, transportability, etc. Various LTER Databits -- Winter 1990 -- page 2 companies in the US build GPS units (including Texas Instruments, Trimble Navigation, etc.).

Developing a Searchable Document and Imagery Archive for the GCE-LTER Web Site

Issue: 
Spring 2008

In 2007 the Georgia Coastal Ecosystems LTER program began its second cycle of NSF funding, and as part of the transition from GCE-I to GCE-II we conducted a top-to-bottom review of our integrated information system. One major conclusion of this review was that we needed to do a better job of managing the various electronic resource files that are acquired during the course of GCE research and project management activities, including documents (e.g. publication reprints, reports, protocols), imagery (e.g. rendered maps, photos, logos) and other types of static files.
