GIS WebServer SE expands possibilities of 3D modelling

19.05.2017

In KB "Panorama" the GIS WebServer SE version 3.2 is developed. In the new version the component of three-dimensional model of a map is updated. The 3D model provides the ability to work and view information layers of various types (vector, matrix and raster maps) for spatial analysis and decision making during designing. 3D surface is created taking into account the terrain. Detailed models can contain three-dimensional objects that correspond to objects of a two-dimensional map. 3D Map allows you to select objects and to get information about them.

In the new version of the component of map's 3D model, the displaying of titles is added, the loading and processing of the terrain is accelerated. The possibility of binding the view of a three-dimensional object to its semantic characteristics is added. In order to reduce the load on the server, there is added the possibility of work with tiles of different size (256С…256, 1024С…1024). In the Map Editor, when you edit and delete an object, there is added a displaying the list of objects that are in the current point. For the active mode of the Editor, this list is an optional possibility for selecting an object.

Toolkit of development of Web-applications the GIS WebToolKit SE has been improved, which expands possibilities 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, 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.
