In KB "Panorama" the Complex of hydrological tasks version 6.3.5 has been developed for the GIS "Panorama" 15. The complex is intended for modelling of hydrological conditions, construction of zones of flooding and drainage. In the new version of the complex the application
For calculation of parameters of a breakthrough wave and characteristics of flooding of the area, initial data is established, which include the data on a reservoir, hydraulic system and river bed in tail-water of a hydraulic structure. Calculations are based on the graphic of water flow from the reservoir. In this case, the river below the reservoir dam is divided along its length into calculated sections, which are limited by calculated targets.
Calculations are performed iteratively along the targets with distance from the dam. To complete the task, a vector map of the area and a matrix of heights of a relief are used. The vector model for calculations includes the dam, river fairway and targets. There can be any number of targets, depending on the length downstream of the river it is necessary to predict the flooding of the area. The choice of the location of the targets should be carried out taking into account the shape of the channel and preferably with uniform intervals between adjacent targets.
Results of modelling are: graphics of the breakthrough wave propagation; the matrix of qualities characterising the flooding of the area, and a vector map with borders of the maximum zone of catastrophic flooding.
Graphics of the breakthrough wave movement are constructed on the Z-L-T plane, where L is the distance from the hydrosystem (abscissa axis), Z is the level mark (left ordinate axis), and T is the time since the destruction (right ordinate axis). The basis of the graphic is the longitudinal profile of the river along its fairway, built in the Z-L plane, on which the maximum water level at the calculated targets during the movement of the breakthrough wave is put. In the L-T plane, graphics of the movement of the front, crest and tail are constructed. Graphs of the movement of a breakthrough wave make it possible to determine the parameters of a breakthrough wave at any intermediate river section and are the initial information for constructing a flood matrix. To model the flood zone, a new algorithm has been developed that uses the matrix of heights of a relief, the river fairway and numerical values of the parameters of the breakthrough wave at arbitrary points of the fairway. Based on the resulting matrix of qualities, a vector object "Zone of maximum flooding" is constructed, which characterizes the zone of catastrophic flooding of the area.

Specialists of KB "Panorama" have prepared a video lesson on creating a multiscale map using the
Multiscale linear and vulgar objects can have several the additional contours created in procedure "Sort of map objects" when generalizing multiscale objects. This speeds up the display of complex objects and makes the terrain more visual.
Additional contours are formed for smaller scales of display - 1/4 1/16, 1/64 from base scale of a map and are recorded into the object metrics together with the basic contour. When compressing the map, those contours of objects that are closer to the current display scale will automatically be displayed. This speeds up the display of complex objects and makes the terrain more understandable. During any editing of the map and when performing calculations based on the object's metrics, the basic contour of the multiscale object is processed. Multiscale objects are one of the elements of a multiscale map that changes its appearance when the display scale is changed.

To manage the development of the territory of a municipality and the development of land plots, it is necessary to comprehensively use information about territorial zoning, land plots and real estate objects. The procedure for an integrated approach is established by the rules of land use and development, which are regulated by the Urban Planning Code of the Russian Federation and include: amap of territorial zoning, urban planning regulations and the procedure for applying the rules. Updated
The improved mode
The algorithm for establishing spatial and logical connections between land plots and objects on the territorial zoning map has been updated. The digital classifier urban.v2.rsc has been updated, which must be used to maintain a territorial zoning map. To connect areas and territorial zones, the spatial location of the area within the zone and the semantics "Index of territorial zone" with the ZoneIndex key are used.
In the new version of the "Workstation of urban-planner" the list of reports has been expanded. The report "Types of permitted use of a territorial zone" contains a list of main, auxiliary and conditionally permitted types of use for a specific territorial zone. The report "Print of urban-planning regulations" includes all types of permitted use with established parameters for the development of a territorial zone. To fill in the parameters of the development of a territorial zone, the functions "Add" and "Add with copying" have been added.
