GIS WebServer SE realistically displays multi-dimensional geospatial data


GIS WebServer SE version 3.9 is developed in the KB "Panorama". In the new version of the program the 3D map displays photorealistic three-dimensional models of unlimitedly large size. The models are presented in a new format of tile vector 3D terrain models - DB3D. As a DB3D data source, there is used the GIS WebService SE of version no less than 12.0.7.

Creation of data in DB3D format is performed in the professional GIS "Panorama". The technology is developed with the use of importing the tile models in TLS (Agisoft Tiled Model) format, point cloud in Agisoft OC3 format or 3D terrain models in COLLADA format. The example of displaying new three-dimensional models is presented on the website. As an example, the model of a part of the city of Tomsk, provided by the company "Geoscane" is used. A high-precision three-dimensional terrain model was obtained using unmanned aerial survey systems and photogrammetric software.Such models are highly informative and expand the possibilities for operational 3D analysis. Mapping the 3D models of DB3D requires a relatively small expenses of the resources of the client application. Managing a transparency of layers of three-dimensional tiles and a background is added.

Possibilities of "Manager of map project " are expanded. The mode provides an opportunity to change the data composition of the map projects. Users can dynamically update the current composition of the map data layers or completely change it. The administration module is updated. A separate page has been added to configure the permissions of the application's users.

The toolkit of developing the 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. Various types of high-altitude data are used as a digital elevation model: matrixes (in the formats SRTM, GeoTIFF, IMG, MTW), TIN-models, point cloud and others. At request the most accurate data onto a specified terrain site with a given resolution is automatically sampled. To transfer data of the digital terrain model to the Web, the WCS protocol is used. The relief data is represented as tiles and cached on the client.

As a source of spatial data, the Databank 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 is available on the website in the Download section.
