NOAA and the Geoportal
This ArcNews article describes how NOAA's National Climatic Data Center (NCDC) uses Esri's geoportal technology to make its geospatial data available to scientists and users all around the world.
Esri Geoportal Server helps you build and administer a geoportal Web site where data producers can register their geospatial resources for users to discover and consume. The geoportal does not duplicate these resources but stores and catalogs the metadata of the resources as well as the information to access those resources.
Geoportal inventories all the metadata of the registered geospatial resources in a geoportal catalog service, which is an Open Geospatial Consortium (OGC) compliant CS-W 2.0.2 service.
Geoportals help you maintain the quality, currentness, and availability of registered resources by providing tools to evaluate new entries, control access to metadata and resources, and integrate the geoportal with other enterprise systems.
Data producers publish their resources to the geoportal by registering the resource's metadata with the geoportal's catalog service; supported resources include datasets, analyses, tools, and Web services. Geoportals include simple tools for generating and registering metadata. Publishers can directly create metadata in the Web application, upload their existing metadata to the geoportal, or allow the geoportal to autogenerate metadata.
Geoportals support and provide templates for several common metadata profiles, including
Geoportals provide an easy-to-use interface for users to discover and access resources registered with the geoportal to use in their own projects. They can trust that they are using the most current, best quality resources available.
