Preparing a map with corrections of registry errors

 Print Previous page Top page Next page

The digital data model for correction of registry errors of cadastral objects is drawn up in the form of a digital cadastral map (DCM). The map should necessarily include the EXISTING objects registered in the EGRN and the CORRECTED objects.

To create and maintain the DCM it is necessary to use the latest version of the survey.rsc classifier. The classifier contains the necessary object codes and semantics used in the process of automatic filling the Report.

STEP 1. To start work, you need to put the initial (existing) boundaries of objects onto the DCM by any way, using codes from the «CORRECTION OF REGISTRY ERRORS» layer:

1)        Land plot according to the EGRN (areal);

2)        Part of the land plot according to the EGRN (areal);

3)        Capital construction object according to the EGRN (areal);

4)        Boundaries of ATE, territories and forestry according to the EGRN (linear).

The priority option for drawing the existing boundaries of objects onto the DCM includes:

a) Creating a map using data from XML files of cadastral plans of the territory, provided in the form of output documents of the EGRN. The mode «Reading the cadastral plan of the territory and updating the map» is used.

b) Recoding objects using the «Change of type» mode. It is necessary to consistently change the type of all cadastral plots onto the codes used when correcting cadastral objects.

Objects registered in the EGRN must have identification and mandatory semantics filled in.

Identification semantics:

-        Cadastral number (1001) for the land plot

-        Registration number (1039) for part of the land plot and for the contours of a multi-contour land plot

-        Cadastral number (1001) for a building, structure, unfinished construction object

-        Registration number in the registry (1109) for the boundaries of municipalities, settlements, territorial zones, forestry

Mandatory semantics:

-        Area according to documents (1015) indicated according to the Unified State Register of Real Estate for land plots, parts of land plots, object of capital construction.

STEP 2. Put the characteristic points of existing object boundaries onto the map using code from the «Correction of registry errors» layer:

-        Characteristic point of the EGRN (point)

Points must have the filled identification semantics:

-        Name (9).

STEP 3. Draw the corrected boundaries of objects on the map by any way, using codes from the «Correction of registry errors» layer:

1)        Land plot the corrected one (areal);

2)        Part of the land plot the corrected one (areal);

3)        Object of capital construction the corrected one (areal);

4)        Boundaries of ATE, territories and forestry areas the corrected ones (linear).

Objects characterizing existing and corrected boundaries must always be paired - each existing one must have a corresponding corrected one. Paired objects must have the same identification semantics value.

Multi-circuit objects (land plots and OKSs) must be presented in the form of multipolygons. External contours are represented by external subobjects. Internal contours are represented by internal subobjects.

STEP 4. Map the characteristic points of the corrected object boundaries using code from the «Correction of registry errors» layer:

-        Characteristic point the corrected one (point)

Points must have the filled identification semantics:

-        Name (9).

When filling the report, the program searches for characteristic points of the same name (existing - corrected). To establish correspondence, the semantics «Name» and identification semantics of cadastral objects are used.

If an existing point is found for the corrected point, then two columns «Contained in EGRN» and «Installed (defined) in order to correct a registry error» will be filled in the tables of information about characteristic points.

If an existing point is not found for the corrected point, then one column «Installed (defined) in order to correct a registry error» will be filled in the tables of information about characteristic points. Such points are considered as new ones.

If a corrected one is not found for an existing point, then one column «Contained in EGRN» will be filled in the tables of information about characteristic points. Such points are considered to have ceased to exist.

When forming a Report, the program uses the following semantics of characteristic points:

-        Method of coordinate determination

-        SKP of point position

Filling in the specified semantics can be done manually or automatically for a group of selected points.

For formation of an XML document, in addition to the specified semantics, the semantics for land plots must be filled:

- «Correction sign» (1352, key SIGN_CORRECTION);

for boundaries of a municipality, settlement, territorial zone, forestry

-        «Type of boundary registry object» (1374, key TypeBoundary),

-        «Type of boundary description» (1373, key AllBorderOrPartBorder).  

When written to XML, multi-contour objects can be represented as multipolygons or sets of objects.

Each contour of a multi-contour object from a set is identified by a registration (sequential) contour number (semantics - PART NUMB (1039, PART_NUMB key)).
