Introduction  This paper will discuss various options of visualizing maps within the SAS Portal environment.  It will illustrate how to build custom Portlets embedding Google Maps, ESRI Maps and Open Street Maps.

GIS Providers  This paper will focus on Google, ESRI and Open Street Maps as GIS providers. There are many other GIS providers out there with similar capabilities and API support.  Legal and technical limitations  Each GIS provider has its own Terms of Use/Terms of Service, e.g. limit max number of accesses, map application must be public and freely available (you cannot charge to access it)  Check the license details of your preferred GIS provider before your start your implementation project

GIS Provider API  A GIS provider API (Application Programming Interface) allows developers to overlay their own customized maps on GIS provider’s base maps (e.g. Google Earth and Google Map). This capability makes it possible to present SAS statistical data graphically on the dynamic maps.  Overview of available API’s: GIS ProviderDetailsReferences GoogleAdobe Flex based APIhttp://code.google.com/apis/maps/documentation/flash JavaScript basedhttp://code.google.com/apis/maps/documentation/javascript ESRIAdobe Flex based APIhttp://resources.esri.com/arcgisserver/apis/flex JavaScript basedhttp://resources.esri.com/arcgisserver/index.cfm?fa=JSAPIs OSMAdobe Flex based APIhttp://openscales.org/downloads JavaScript basedhttp://

GIS integration with SAS  SAS Portlets are the simplest way of integrating 3 rd party content in the SAS Information Delivery Portal.  SAS also provides API for Portlet development.  SAS Portlets are the information display components of the SAS Information Delivery Portal.  A Portlet can process requests from the user and generate dynamic content such as report lists, alerts, workflow notifications, or performance metrics.  Each of the Portlets described in this paper uses HTTP to communicate to GIS providers as well as to execute SAS services.

Google Maps Portlet  This Portlet will embed Google Maps into the SAS Portal environment. It utilizes Google’s Flex API in order to communicate with the map provider.

ESRI Map Portlet  Support of multiple map layers provided by an ArcGIS server. Map layers can provide different detail level, e.g. terrain data, demographics, weather maps, etc.

OpenStreetMap Portlet  This Portlet displays base maps provided by the OpenStreetMap (OSM) community. OSM is a free editable map of the whole world. The maps are created using data from portable GPS devices, aerial photography, other free sources or simply from local knowledge.community

Why SAS  SAS Portlets provide a powerful solution for embedding geospatial data into the SAS environment.  Use SAS analytic capabilities to drive map overlays and markers.  Us native SAS and GIS vendor capabilities to ensure rich applications with all the zooming and navigating features still reserved.

Requirements  Adobe Flex Builder to compile the projects  All custom Portlets described in this paper can be downloaded (including source code): is_with_SAS_Portal is_with_SAS_Portal  SAS Enterprise BI Server to host the SAS Portlets  Internet/Network connection to access GIS provider base maps
