National Geothermal Data System funded by Department of Energy


The Department of Energy (DOE) awarded a three-year 18-million dollar grant as part of the American Recovery and Reinvestment Act (ARRA) to the Association of American State Geologists (AASG).  Eighty-five percent of the funds are slated for the 46 participating states for compiling, digitizing, and documenting data for populating the National Geothermal Data System (NGDS).


USGIN Amazon Virtual Server Development

Documenting the process of development of a Web Server in the Amazon EC2 environment. Software installations tailored to the requirements for USGIN

This blog will serve as preliminary documentation for the development of the AZGS Amazon EC2 Instance. The purpose of the machine is to:

1) Provide a production environment for USGIN CSW, WMS and WFS services through GeoNetwork and GeoServer by the Arizona Geological Survey.

2) Provide a model (and AMIs) for other organizations to use in order to build their own Amazon EC2 instances to provide USGIN services.

AASG NSF Interoperability Project


One of the major projects currently developing US Geoscience Information Network capabilities is named the Geoscience Information Network (NSF GIN).  This project provides funding to assemble key modules and adopt standards and protocols to build an interoperable national Geoscience Information Network (“GIN”) that already has strong community engagement and broad consensus. The GIN is being developed in the context of national and international communities for enhanced global geospatial data interoperability. In an NSF-sponsored workshop, the nation's geological surveys agreed to the development of a na-tional Geoscience Information Network (GIN) that is distributed, interoperable, uses open source standards and common protocols, respects and acknowledges data ownership, fosters communi-ties of practice to grow, and facilitates development of new web services and clients. Geological surveys have an estimated 2,000 – 3,000 databases that represent one of the largest, long-term information resources on the geology of the United States and collectively constitute a national geoscience data “backbone” for research and applications.

Building a GeoSciML WFS Server

Development, testing and implementation of a WFS service that returns GeoSciML documents

I want to help make the process of building a GeoSciML WFS server easier. I'll be collecting links to relevant information, cookbooks, walkthroughs, etc. Hopefully this will chronicle my process of going from knowing practically nothing about how to implement a service to making one work.
