8.3.4 Envitia Catalogue Service and Supporting Services
The Envitia OGC Catalogue Services for the Web CSW services provided a supporting capability in the exploitation subsystem. Envitia’s catalogue can accept both services delivered in the sub-system these were for
example web map services using data from the UK Hydrographic Office and external services in this case the MOGIE WFS via the Mediating WMS, the Esri Imagery WMS and the Exact Earth AIS WMS and provide the
user with an extensive search capability to discover and evaluate the various services together. As well as the CSW and the foundation chart WMS Services, DMarGS also provided a Tidal Data WMS, a Climatology Data
WMSWPS and a Gazetteer service.
8.3.5 Envitia HTMLJavascript Portal
The Envitia JavaScriptHTML portal is designed to operate on a wide range of browsers.
Figure 27 - Envitia Portal showing MOGIE data The portal interacts with the catalogue service to identify resources it can exploit and then accesses those
services to provide a wide range of functionality. The Envitia Portal does not require any form of plug-in, and is implemented completely in HTMLJavascript.
8.3.6 Envitia Browser Portal
Envitia also exploited its MapLink Pro Mobile developer kit to develop an Android based app capable of exploiting both the MOGIE and other DMarGS services and deliver a common operating picture both on-line
using the OGC OWS Context Standard and Off-line using the OGC Geopackage standard.

8.3.7 Esri ArcGIS Desktop
Esri is an international supplier of GIS software with many government users. Their ArcGIS software suite is heavily focused on interoperability and supports numerous OGC standards as a result. ArcGIS was used to
demonstrate the land scenario from an existing client, namely ArcMap, which required no additional software development. The interoperability extension was used to configure and connect to the WFS service and interpret
the returned GML. The tracking analyst extension’s playback feature was used to replay the scenario data.

Base Map The background imagery was accessed via the WMTS service described in Section 8.4.1. ArcGIS Desktop can
connect to WMS, WMTS and WCS services natively via ArcCatalog. The imagery layers can then be viewed in ArcMap.
WFS – Interoperability extension ArcGIS Data Interoperability enables data sharing by providing direct data access; data translation tools; and the
ability to build complex spatial extraction, transformation, and loading ETL processes. ArcGIS Data Interoperability allows one to use any standard GIS data within the ArcGIS for Desktop environment for
mapping, visualization, and analysis. The Workbench application, included with the extension, enables one to build complex spatial ETL tools for data validation, migration, and distribution.
Using ArcGIS Data Interoperability, one can directly read more than 100 spatial data formats, including GML, XML, WFS, Autodesk, DWGDXF, MicroStation Design, MapInfo, MIDMIF and TAB, Oracle and Oracle
Spatial, and Intergraph GeoMedia Warehouse, and export to more than 70 spatial data formats.

Symbology The MIL-STD-2525D symbology displayed was manually added using ArcMap’s Symbology editing tools
found in the layer editor like any other layer in ArcMap. The set of PNG symbols were pre-rendered for the MOGIE experiment.
Playback ArcGIS Tracking Analyst extends the time-aware capabilities of the ArcGIS system with advanced functions to
view, analyze, and understand spatial patterns and trends in the context of time. By providing tools for time- dependent symbolization and time-based analysis, ArcGIS Tracking Analyst automates and enables the tracking
and discovery of time-related trends and patterns.
