GIS WebServer SE uses an interactive globe model to display geospatial data


In KB "Panorama" the GIS WebServer SE version 3.3 is developed. In the new version the component of three-dimensional model of a map was updated. The 3D model provides an opportunity to work and to view information layers from the geospatial data base and remote sensing data for analysis and decision making at designing. 3D surface is displayed in accordance with the terrain. Detailed models can contain three-dimensional objects corresponding to objects of a two-dimensional map. The new version adds the ability to automatically change the composition of the displayed three-dimensional objects depending on the scale of the map display. Animation of moving and continuous display of 3D maps are added at movement along equator.

For small scales of display the spherical model of a terrestrial surface is formed. When solving various navigational tasks, the spherical model allows you to explore the globe in a Web browser, to view cities, countries, continents, analyze their mutual location, and also make a quick transition to any point on the globe.

Search system is updated. The ability to select a search resource for address search and search by coordinates is added. This allows you to obtain geodata from various sources in the user interface. Management of map scaling is optimised, image animation at changing a scale of displaying a map is added. In the administration module there is added a customizing the parameters of several systems of address search, search by cadastral number on the portal of Rosreestr. There is added the ability to customize the boundaries for displaying 3D objects by scale.

The web applications development tool the GIS WebToolKit SE has been refined, which extends the capabilities of GIS WebServer SE and can be integrated into other information systems. Access to data (images, vector maps and terrain information) is provided by Web services using common OGC protocols and ISO standards. Service GIS WebService SE (OGC WMS/WMTS) provides spatial information in the form of graphic images. As digital model of a relief the various kinds of high-altitude data are used: matrixes (in formats SRTM, GeoTIFF, IMG, MTW), TIN-models, a cloud of points and others. At request there is carried out the automatic sample of the most accurate data onto the specified terrain site with a given resolution. To transfer data of the digital terrain model to the Web, the WCS protocol is used. The relief data are represented as tiles and are cached on the client.

As a source of spatial data, the Data bank of digital maps and remote sensing data can be. It provides the collection, storage, search and delivery of spatial data in exchange formats, a displaying the state of the data bank in the form of maps-schemes, the automated formation and updating of geo-covers.

GIS WebServer SE is used in the construction of closed corporate systems to ensure the protection of data having a security classification or a trade secret. GIS WebServer SE is certified for Level 2 of absence of undeclared capabilities. The new version of the program expands the application's capabilities in solving problems of analysis, management and long-term planning of the territories development. GIS WebServer SE is implemented using the toolkit of GIS WebToolKit SE, which can be used in development tools that use the JavaScript.

The new version of the program, documentation and presentation are available on the web-site in the Download section.
