Company Profile

MapMakers Group Ltd. is the leader in development of meteorological software for processing and delivery of meteorological information in Russia. The main software product developed by MapMakers Group is the meteorological geographical information system - GIS Meteo.

GIS Meteo is an interactive, real-time tool primarily designed for use in meteorologist's operational work. It can also be successfully used in related areas, such as agrometeorology, hydrology, oceanology, etc. GIS Meteo creates meteorological maps using data provided by various databases, such as meteorological real-time database, satellite images, the WMO Global Telecommunication System (GTS), Internet, SADIS and others. GIS Meteo has a simple and friendly user interface for working with maps, graphs, diagrams and etc. Separate GIS Meteo applications realize a greater number of numerical methods.

With GIS Meteo you can place on the map in any projection and scale practically any kind of meteorological data from observational data to forecast fields. GIS Meteo provides a great number of data presentation forms: numeric, isolines, color areas etc. GIS Meteo includes a great number of components, realizing various numeric methods, for instance, trajectory calculations, calculation of frontal areas, clouds, precipitation, thunderstorms, turbulences, icing of the planes, jet streams, fire danger and many others. Numeric methods can use actual and forecast data. GIS Meteo also includes separate applications designed for hydrometeorologists and agrometeorologists.

In GIS Meteo you can create templates of complex multi-component maps and generate them at specified moments automatically. The possibility of combining any kinds of source meteorological data and the results of numeric methods on the same map gives birth for absolutely new technology of the meteorologist working on the weather analysis and forecast – paperless technology.

GIS Meteo was successfully certified in Roshydromet and recommended for using in all its regional meteo services.




GIS Meteo toxi

The TOXI component of the GIS Meteo software package (TOXI+GIS Meteo Component) is used to assess the propagation zone size of the hazardous factors of industrial accidents with the toxic agents release into the atmosphere considering the current or the forecasted data on the weather conditions in the place of release.
The surface data in the GRIB code for all advance times are required for calculations.
The component is developed in accordance with the requirements and provisions of the applicable regulatory and procedural documents of the Federal Service for Environmental, Technological and Nuclear Supervision.
1.    TOXI. Edition 2.2. Assessment methods for chemical accident consequences. Approved by the State Committee for Supervision of Industrial and Mining Practices of Russia. 2001.
The methods are used to model the dispersion of hazardous substances in the atmosphere, the density of which at the specified weather conditions is lower than the density of the ambient air (“light gases”).
2.    RD 03-26-2007. Guidelines for the assessment of hazardous substances accidental release consequences (the procedure is approved by Order No.859 of the Federal Service for Environmental, Technological and Nuclear Supervision of December 14, 2007).
The procedure is used to model the dispersion of hazardous substances in the atmosphere, the density of which at the specified weather conditions is higher than the density of the ambient air (“heavy gases”).

The basic features of the TOXI+GIS Meteo Component:

The component contains a graphic user interface to specify the basic parameters of the reservoirs, which contain the hazardous substances, as well as their location on the slides of the TOXI+GIS Meteo software package;
The component includes thedatabase of substances, which have a toxic effect on people. The base contains over 20 names of such substances and is equipped with a graphic interface to edit their properties and add new ones.

TOXI+GIS Meteo component is used to:

assess the amount of the hazardous substance released into the atmosphere as a result of full destruction of the reservoirs, in which the hazardous substance can be stored in the gas and/or liquid state;
define the impact zones from several sources of the hazardous substances release into the atmosphere;
assess and visualize the consequences of the hazardous substances release in accordance with the meteorological conditions;
support the automated mode of the meteorological data updating;
display the calculated impact zones on the slides of the GIS Meteo software package.

 TOXI+GIS Meteo component is not used or is limited in use in the following cases:

Hazardous materials dispersal calculations in no-wind conditions;
Indoor release propagation calculations;
Release propagation calculations outside 20-30 km range from the release point;
Release propagation with a hazardous substance mass over 500 t in the peak discharges cloud;
Propagation of the clouds from spilling the hazardous substance over 250,000 m2 in area;
Obstructions in the way of a cloud, the sizes of which are similar to or bigger than the cloud size;
Dispersal of solid hazardous substances;
Fall of the condensed phase on the underlying surface and its repeated release into the atmosphere.

 TOXI+GIS Meteo component is recommended for use for:

designing manufacturing facilities, where hazardous substances are produced, used, processed, generated, stored, transported, disposed of ;
developing measures on the personnel and population protection from accident consequences;
predicting accident consequences at hazardous production facilities using toxic and explosive substances considering the  operational and forecasting meteorological situation;

 The user target group of the TOXI+GIS Meteo component:

Governmental  and municipal authorities responsible for environment monitoring;
Heads of hazardous production facilities.
