7.2 WXXM 1.1 WCS 2.0
7.2.1 GMU
The NOAA GOES Wind Products WCS for OWS-8 Aviation is providing access to the NOAA GOES satellite derived high density Wind products: Cloud Drift Wind and Water
Vapor Wind.
These products consist of point-based measurements about the air temperature, air pressure, wind direction and wind speed, along with the exact geo-location where the
measurement was performed.
This WCS exposes GetCapabilities, DescribeCoverage and GetCoverage operations. For the GetCoverage operation, users may define the bounding box and temporal range that is
of interest. The range subset on a specific field can also be defined. There are two formats that this WCS can return: WXXM and KML.
For more detailed information about this WCS, go to: http:geobrain.laits.gmu.eduows8aviationWCS.html
7.3 FPS
7.3.1 Carmenta
The Carmenta FPS is built on Carmenta Server, which is an OGC-compliant geoserver implementing WMS, WFS and CSW interfaces. In OWS-8 it is used as an FPS for
portrayal of ICAO symbology using SLDSE.
Within OWS-8 support for AIXM 5.1 has been implemented by building a generic XML reader identifying GML-features.
Within OWS-8 Carmenta has successfully implemented support for AIXM and used it for portrayal of aeronautical features according to ICAO standards.

7.3.2 Envitia
7.3.2.1 Introduction
The Envitia FPS comprises an implementation of the WMS specification. Versions 1.0.0, 1.1.1 and 1.3.0 are supported. The FPS functionality is provided by a plugin to the
Envitia Web Services WMS component. The purpose of this Envitia FPS is to support the OWS-8 Aviation demonstration participants in creating their demonstrations.
The available data and capabilities of the component can be explored by visiting the Envitia Services website
1
and following the Services link top right corner to the FAA Demonstrator
2
. This demonstrator has been configured as the OWS-8 Aviation Demo portal. The portal is best viewed in Mozilla Firefox.
7.3.2.2 Standard Functionality
Interaction with this component is exclusively via KVP-encoded HTTP GET requests. The FPS connects to the available WFS components to obtain AIXM data. The data is
then rendered using an FPS client specified SLD. The SLDs are stored in a portrayal registry.
7.3.2.3 Specificnew Functionality
In addition to the standard WMS capabilities, the Envitia FPS component also allows clients to request terrain and airspace profiles or “cross sections” as they are named in the
Envitia Services portal. This can be seen by browsing to the OWS-8 Aviation Demo portal. Simply open any of the Common Operating Pictures available, select the Cross
Section tab and then use the XZ tool to select a start and end point for the profile query.
No new FPS functionality was added to Envitia’s components as part of this project.
7.3.2.4 Available Data
Snowflake, Luciad and COMSOFT WFS have been consumed and are available as rendered WMS layers from the FPS when a valid SLD is specified in the WMS request.
