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.

8.3.8 FalconView Desktop
FalconView is a mapping system created by the Georgia Tech Research Institute.GTRI It displays various types of maps and geographically referenced overlays. Many types of maps are supported, including aeronautical
charts, satellite images and elevation maps. FalconView also supports a large number of overlay types that can be displayed over any map background including KML, GML, AIS, and NMEA. FalconView 5.1 was used to
demonstrate the maritime scenario as an existing client that required no additional software development.
The FalconView KML overlay was used to interpret the KML returned from the server. While FalconView does have WMS client capability, this is designed for raster and imagery output formats. However, the KML overlay
supports retrieving data from a URL. So to retrieve the data, a WMS GetMap request was predefined and passed as the URL to the KML overlay. The playback tool was used to replay the scenario data. Figure 30 shows
FalconView rendering the maritime vessels while displaying the vessel information of the selected Coast Guard ship.

Figure 30: Maritime scenario in FalconView The base map is Landsat imagery provided by NASA in MrSID format. This and many other types of imagery
are typically loaded into FalconView’s data manager to be organized and stored onto the local hard drive. Spatially relevant imagery sources can then be easily swapped to quickly compare the vector data on multiple
base maps. As an example, this would allow attack response coordinators to quickly view the vessel data overlaid on satellite imagery as well as nautical charts.
FalconView loads and replays the data as KML, using the method described in Section 8.2.2. The KML overlay supports most KML features including regions, network links, styles, timestamps and timespans. While
FalconView does support common military symbology standards, such as MIL-STD-2525, the styles specified in the KML document were used for MOGIE.
Because the KML overlay extends the broader FalconView overlay software architecture, other commonly used overlay tools are available for KML datasets, such as feature playback. An example is shown in Figure 31.

Figure 31: Playback Dialog in FalconView The playback tool can be used with any supported temporally enabled vector format including AIS, NMEA,
GML, and KML. In the case of MOGIE, FalconView uses the timespan and timestamp elements defined in the KML to determine when the appropriate features must be rendered.
