USGIN WMS profile for integrated geologic map Web Map Services

Tags:

The key to interoperable map services is the ability to portray adjacent maps using the same symbolization scheme such that when the maps are displayed, the visual discontinuity at the boundary is minimized. Because of the discrepancies in mapping interpretation and intention, there are commonly discontinuities in the definition of map units between geologic maps produced by different authors or at different times. These discontinuities cannot be avoided, and resolving them is a compilation process that will often require additional field work; this is outside the scope of service deployment. What can be avoided is visual discontinuity related to portrayals based on different classification schemes on adjacent maps. Map unit classification schemes for regional geologic maps typically define units based on some combination of age, genesis, and lithology. The larger the area over which the scheme is meant to apply, the more generalized the definition of the units must be.

The USGIN Catalog and Data Services website (http://catalog.usgin.org) hosts several geospatial metadata catalog (CSW) and geospatial data services (WMS, WFS, WCS) implementations and clients. Although the site functions as a showcase of USGIN service implementations, the Catalog Service for the Web service (CSW - http://catalog.usgin.org/geonetwork/srv/en/csw) is a primary metadata node for the U.S. Geospatial Information Network.

Available services and clients at this time:

GI-go GeoBrowser

Tags:

GI-go is a graphical desktop client developed to easily demonstrate the capabilities of the GI-cat catalog service. User make distributed queries based on common search criteria (where, when, who, what) and gets metadata results from a variety of data sources. Data preview and download is also supported.

Distributed search on a variety of data sources:

  • WCS 1.0, 1.1
  • WMS 1.3.0, 1.1.1
  • WFS 1.0.0
  • CSW 2.0.2 Core, AP ISO 1.0, ebRIM/CIM, ebRIM/EO
  • THREDDS 1.0.1, NEW 1.0.2
  • Accessors for GeoNetwork (tested with versions 2.2.0 and 2.4.1) and deegree (tested with version 2.2) catalog services
  • OpenSearch accessor
  • GENESI RDF OpenSearch accessor
  • Download and visualization of XML metadata
  • CDI 1.04, 1.3
  • GI-cat 5.x, 6.x
  • GBIF

GI-cat

Tags:

GI-cat is an implementation of distributed catalog services made by ESSI Lab:

  • Allows clients to discover and evaluate geoinformation resources over a federation of data sources;
  • Allows different clients to use the service, as it publishes different catalog interfaces.

A data provider can deploy his/her own GI-cat instance, grouping together disparate data sources, to accommodate his/her user needs.

Data sources:

  • OGC WCS 1.0, 1.1
  • OGC WMS 1.3.0, 1.1.1
  • OGC WFS 1.0.0
  • OGC CSW 2.0.2 Core, AP ISO 1.0, ebRIM/CIM, ebRIM/EO
  • THREDDS 1.0.1, 1.0.2
  • CDI 1.04, 1.3
  • GI-cat 5.x, 6.x
  • GBIF
  • GeoNetwork (versions 2.2.0 and 2.4.1) catalog service
  • deegree (tested with version 2.2) catalog service
  • OpenSearch accessor
  • GENESI DR OpenSearch accessor 

Profilers:

ESRI ArcExplorer

Tags:

ESRI's ArcExplorer is a lightweight, no-cost GIS data viewer. Note that the .NET version of ArcExplorer is significantly different from the Java edition.

ESRI ArcGIS Server

Tags:

ArcGIS Server is ESRI's network- and webservice-centric GIS application suite. Among other, ArcGIS Server offers WMS, WFS, WFS-T, WCS, and KML service capability as well as web application SDKs for JavaScript, Flex, Silverlight, .Net, and Java.

ESRI ArcGIS Desktop GIS

Tags:

ESRI's ArcGIS Desktop GIS application suit includes popular GIS applications such as ArcMap and ArcCatalog.

Geoserver

Tags:

GeoServer is an open source software server written in Java that allows users to share and edit geospatial data. Designed for interoperability, it publishes data from any major spatial data source using open standards.

Being a community-driven project, GeoServer is developed, tested, and supported by a diverse group of individuals and organizations from around the world.

deegree

Tags:

deegree is a Java Framework offering the main building blocks for Spatial Data Infrastructures. Its entire architecture is developed using standards of the Open Geospatial Consortium (OGC) and ISO/TC 211 (ISO Technical Committee 211 -- Geographic Information/Geomatics).
