This poster outlines the general goals of the National Geothermal Data System, describes its relationship to the US Geoscience Information Network, and shows some of the ways that the Arizona Geological Survey plans to make it easier for individual state surveys to contribute information to NGDS. It was presented in Sacramento by Ryan Clark at the Digital Mapping Techniques 2010 conference.

"Restarting" the Virtual Machine

You can't actually restart it, instead you essentially delete it and roll-back to a prior machine image.

Following are the two Drupal 6 content types that define the USGIN Document Repository (you may want to familiarize yourself with general Drupal concepts):

Collection (ct_collection)

The Collection content type acts as an arbitrary logical unit (or container) that groups the Document-like Information Object (DLIO) nodes which hold the actual data resource. At this time, Collections fulfill 3 objectives at once. Perhaps, they need to be separated at a later point.

Following is how we modified the Views Bonus Pack module for Drupal 6 to generate ISO 19139 XML metadata files for the USGIN Document Repository. This hack can be be used to relatively easily generate other XML metadata (FGDC, CSW records) or most complex XML. Ideally, this hack will evolve into a separate module. If you are interested or have questions, please participate in the Generate ISO 19139 metadata record XML files Views Bonus Pack issue thread.

Overview

The goal is to generate minimum ISO 19139 dataset metadata XML files (that conform to the USGIN profile) from the core and CCK fields used in the repository's Collection (ct_collection) and Document-like Information Object (DLIO, ct_dlio) content types.

User Administration

Tomcat kept running out of memory when running it as a service from within Eclipse. Following is a solution:

Double-click on your Tomcat service under the Servers tab, and click on the "Open launch configuration" to open the Tomcat launch configuration window. On the Arguments tab, append the two following lines in the "VM arguments" form window:

-XX:MaxPermSize=128m
-Xmx1024m

In order to create metadata for both static datasets and dynamic, online services and for use with CSW, the OGC created an xml schema that merges the schema for ISO19115 (dataset metadata) and ISO19119 (service metadata) (see secion D.1.5, page 105 in OGC 07-045). The way that was accomplished was by creating a schema located at http://schemas.opengis.net/csw/2.0.2/profiles/apiso/1.0.0/apiso.xsd. The contents of that schema are quite simple -- it looks like this:

Setup the MySQL Database for Geonetwork to Use

1. From the command prompt on the instance, type the following commands:

   mysqladmin create geonetwork -u root -p

   You will be prompted for the password for the root MySQL user.

 This is an example Python script that showcases GeoNetwork authentication, session handling, and CSW transactions.
