The results of research work on the use of open data for geoinformation mapping and data analysis for solving applied business problems and managing territories using the GIS "Panorama" software will be discussed at the II Scientific and Discussion Student Club of the CIS countries. The discussion will take place within the framework of the student week from May 24 to May 26 at the conference "Spatial data: Science and Technology 2021", organized by the Moscow State University of Geodesy and Cartography (MIIGAiK).

The conference "Spatial Data: Science and Technology 2021" is an annual international scientific platform organized by MIIGAiK with the participation, as partners, of leading industrial companies, federal regulators of requirements and standards in the field of spatial data. The goal of the conference is to form an international platform for scientists and researchers from various fields of knowledge, using spatial data as unique characteristics of objects and phenomena of the world around us.

Within the framework of the scientific-discussion club, students and young specialists, with the technical support of KB "Panorama", work out scientific and practical issues on the use of geodata for business, state and municipal administration of territories. To conduct research, participants use software the GIS "Panorama", GIS Server, GIS WebService SE, GIS WebServer SE and the developer's toolkit GIS ToolKit. The topics of the reports can be found on the "Schedule" page in the section "Open Data - Competition for Applied Scientific Research of Students, Postgraduates, Young Scientists".

This year the conference is being held in a remote format. To listen to the reports, you must connect to the broadcast at the specified date and time by selecting the desired section of the conference.

Specialists of KB "Panorama" prepared and placed on the geoportal "Bank of spatial data" the map of the Republic of Adygea. The map was formed using OpenStreetMap data, source data was obtained from Geofabrik website. To work with the map, you can use the GIS Panorama Mini program or other software products of KB "Panorama".

The map was led to the modernised classifier of large-scale plans of scale 1: 5 000 (map5000m.rsc) and was saved into a packed project (MPTZ). The MPTZ format project includes a digital map of the region's territory (country, subject of the federation, administrative region), a map of the administrative-territorial division of the region and a digital classifier. Publishing of updates in bank of spatial data is made by using the program of Databank of digital maps and remote sensing data. Publishing contents of bank of spatial data on the geoportal and data access for downloading are implemented by means of GIS WebServer SE.

Free maps on the basis of OpenStreetMap data are available for download on the page "Digital maps".

In KB "Panorama" the GIS WebService SE version 13.10.1 has been developed. The new version of the service performs calculations on a cloud server, providing remote access to spatial information for users. For complex information systems, an important indicator is the volume of information transmitted through the cloud over the network. In order to increase the throughput, a new protocol for interacting with the service in the JSON format has been developed. Using JSON will reduce the traffic for transferring requests and responses by an average of 4 times compared to XML-RPC. The use of the JSON standard will simplify the process of integrating the service with third-party systems and libraries. To reduce the size of the transmitted parameters, the ability to set common parameters for all layers has been added into the request structure.

Security of the service work has been increased when exchanging data via sockets with the PHP module. All addresses are closed except 127.0.0.1. Now to the GIS Application Service module , the requests through sockets can be submitted only from the local machine. In order to reduce the size of the recorded event logs, their formation is divided by days. Tools of writing the user libraries by means of SDK have been expanded. Examples on creation of the dispatching centre with moving objects were added.

Interface of the administrator has been improved. A new dialog for monitoring the process of loading data into RAM, forming a cache from the GIS Server, and forming a cache of a dbm layer from a database has been implemented. For loaded systems, the ability to preload data into RAM has been added to speed up the process of accessing data by users.

There is implemented a request to control the metric of an object for self-intersection and junction of contours, search for close points and outliers, and determine the location of contours. For the operation of checking the intersections of two or more layers, an indication of the request execution has been added. For compatibility with old versions of GIS WebServer SE, support for the GetMapList request has been added.

GIS WebService SE supports all international standards (OGC WFS, WFS-T, WMS, WMTS, WCS), which are used to transfer and display spatial data. The program implements the ability to issue tiles for any user or local coordinate system. The application is implemented on Windows and Linux platforms, is compatible with Apache, IIS and nginx web servers.

The new version of the program and the documentation are placed on the website in the Download section.

Specialists of KB "Panorama" have updated the digital map of Administrative-territorial division of Russia in SXF format. The map is formed according to OpenStreetMap data from Geofabrik website. It contains territories of federal districts, subjects of the Russian Federation and administrative regions. Total number of objects is 5188.

OKATO codes correspond to Rosstat and FIAS data. The map can be used for the analysis and assessment of territory of the Russian Federation and its subjects, assessment of the borders length and as a basis for creating thematic and special maps.

To work with the resulting map, you can use the GIS Panorama Mini program or other software products of KB "Panorama". Free maps based on OpenStreetMap data are available for download on the "Digital maps" page.

In KB "Panorama" the "Workstation of agronomist" version 13.6.6 has been developed. The new version adds support for working with Earth remote sensing data from the VEGA-PRO service, created by the Space Research Institute of the Russian Academy of Sciences - IKI RAS in cooperation with LLC "IKIZ".

VEGA-PRO is a professional information service that provides access via the WMS protocol to archived and up-to-date data, daily updated satellite images in natural colors and thematic products based on them for analyzing the Earth's surface and monitoring renewable biological resources. The service provides data obtained from satellites LandSat, Sentinel, MODIS, TERRA, KANOPUS, METEOR, RESOURCE and others. A full description of the service's capabilities is available in the documentation.

As part of the "Workstation of agronomist", the service is available in the form of geoportals with layers of coverage based on satellite images in natural colors, a large number of different vegetation indexes and thematic products: smoke, fires, temperature of ocean surface. A layer of coverage with images in natural colors can be used in tasks of monitoring the Earth's surface, for example, for assessing forest and land resources. The images clearly show the change in the forest area caused by fires, deforestation or destruction of the timber stand, as well as the overgrowing of agricultural lands with forests due to their underutilization.

Vegetation indexes are numerical indicators of the quantity and quality of biological resources, calculated on the basis of satellite images. Depending on the type, the indexes can be used in the tasks of assessing the health of vegetation, predicting yields, or determining the effectiveness of fertilization. Indexes NDVI, GNDVI, PVI, SWVI, SAVI, NDRE, MNDVI, AWEI, WRI, NDWI, NDMI are available for viewing.

Thematic anomalies provide information on fire and smoke based on multispectral satellite imagery. "Workstation of an agronomist" provides data content management for all layers from the VEGA-PRO geoportal by using the tools of filtering the source images by date of shooting and total cloud cover.

Access to the service is provided by username and password or by an API access key. The options for providing access are described in the documentation on the service website.

The new version of the program is available on the website in the Download section.
