This article aims to present selected features of the GeoMedia WebMap with Geospatial Portal - Classic. Selected and shown features are relevant for establishing powerful GIS solutions on the web.
To run fully working Geospatial Portal - Classic demo go to http://demo.hexagongeospatial.com/webgis/
GeoMedia WebMap enables you to build a geospatial interactive web site or web service. GeoMedia WebMap provides direct, real-time access to geospatial data warehouses and all geospatial formats supported by GeoMedia. And, it provides all of the spatial analysis functionality of GeoMedia. This means that you can use it to build a web site that gives thin web clients powerful, dynamic, and open geospatial capabilities, previously available only in a desktop application. Further, it provides web presentation technology and fully scalable web architecture. The web presentation technology allows you to generate your maps in either a raster or vector format, suitable for transport and rendering over the web. The scalable web architecture provides a server-side technology for ensuring that your web application will scale to meet the needs of web clients as usage demands increase.
Geospatial Portal - Classic is an easy-to-use web client application and provides fundamental capabilities for users consuming spatial data.
Note: Workflows in this article demonstrates GIS operations in 2D display mode. Geospatial Portal also supports a 3D experience with robust functionality.
If you are interested in these capabilities, you will find a 3D focused workflow, in another article named ‘3D GIS,’ and related demo instructions also available on the same server, from the Hexagon Geospatial demo server page.
3D mode is available in Geospatial Portal by default. Therefore, you can turn on the 3D mode in this 2D-focused demo, but it is not recommended. In order to support 3D view, Geospatial Portal leverages the native support for WebGL in selected browsers.
Geospatial Portal - Classic user interface consists of the following functional blocks which will be often referred in the subsequent steps of this workflow:
The map compositions predefined by an administrator are demonstrated in a form of map buttons localized in the upper right corner of the map window. The available map layers of the selected map composition are displayed in the Map content panel on Sidebar.
Run Geospatial Portal - Classic, available at http://demo.hexagongeospatial.com/WebGIS/ and start exploring its features.
Simple thematic map designer in Geospatial Portal - Classic lets you define and display thematic maps based on attribute data. All vector geometry types can be mapped thematically and will update when the source data changes.
Preparing a thematic map it is possible to filter feature class objects using different criteria, by selecting an attribute for classification.
Navigating the maps displayed in Geospatial Portal - Classic is intuitive and can be performed in many ways using different tools.
In the Data Window, you can display feature classes and attribute values for selected data sources (for example WebMap Publisher, WFS, or PSS).
Vector data (displayed form WMPS or WFS) can be filtered in the map window. The filter can be set separately for every feature class layer. Objects can be filtered in the map window using the attributes that are available for them.
Geospatial Portal - Classic provides a range of tools for performing simple measurements on the map. Use the measurement commands on the toolbar to measure the distance, area, and get the point coordinates.
With Geospatial Portal - Classic powerful analysis functions, you can perform various types of spatial and attribute queries.
When you registered in Geospatial Portal - Classic a WMS with time parameter, you will be able to track the changes to a phenomenon in time and space.
NOTE: For this demo purpose some public services from third parties are used thus the sustained working of these services is not guaranteed.
NOTE: You don’t have to log in to the Geospatial Portal. All editions of Personal service are performed only for the time of one session.
This instance of the Geospatial Portal - Classic has been configured with a WFS-G (Gazetteer) services connection allowing you to perform searches for POI database:
You can also search for geographic names with the search dialog on the sidebar:
You are using a full-working version of the Geospatial Portal - Classic for this demonstration. There are many additional command and capabilities beyond what has been provided in the demonstration. Feel free to explore and use all of the commands available and/or to explore the User Guide by choosing the About button on the toolbar, and then choosing Guide.
