The accuracy sintar of the cadastral maps according to Decree No. 26 / 2007sb. as amended determine

She launched an interesting service that will protect sintar you against sintar accidental operation of your property. Of practice there are cases where using a fake contract or power of attorney, the property was directly in the real estate stolen or encumbered loan. More information on www.hlidacipeskatastru.cz.

Cadastral maps encountered are of varying quality, form, scale, coordinate system. The quality sintar and form are closely related. Quality is understanding the degree of accuracy of map making and the form is meant, in what format are processed cadastral maps (raster, vector). sintar The coordinate system is different and its history dates back to the reign of Maria Theresa and Joseph II., Which was used Gusterberský and St. Stephen's coordinate system (for the area in the Shah's scale, which corresponds to a scale of 1: 2880). It is currently only used JTSK coordinate system (the system Uniform Trigonometric Cadastral Network) metric values. Establishment and historic cadastral sintar description of these works is described in history.
In the Czech Republic we encounter sintar four types of formats sintar cadastral maps. They are DKM, KMD, KM-D and analog sintar maps. Part of the area has for its cadastral producing the so called. DKM map (digital cadastral map), which is accurate and current map work throughout in vector format. Another part of the territory is covered by cadastral map called KMD (digitized cadastral map), KM-D (digitized cadastral map "with a hyphen).
For areas where there were no level of digitization of cadastral maps are kept in plastic film (analog map). DKM (digital cadastral map) - a continuous vector map work in the coordinate system S-JTSK. There is a renewal of the operators mostly new mapping, or reworking existing CN map at a scale of 1: 1,000 and 1: 2 000 emblem is higher quality, which is given far greater accuracy (quality) points. KMD (digitized cadastral map) - This is a transfer analog to digital maps on the basis of the new Guidelines sintar for the renewal of cadastre. As part of ongoing recovery orientation identical points in S-JTSK. Bitmaps are transformed into identical points, focuses actual condition and are reconciled cadastral boundaries. This kind of cadastral maps arises from the assumption of 2009 to 2015 over maps at a scale of 1: 880 KM 2-D (digitized cadastral map "with a hyphen") - was recast analog maps in the coordinate system Gusterberském or St. Stephen's in digital form. The map has lower accuracy points.
Conversion of cadastral maps in digital form is one of the most important tasks of the department. Vector cadastral map may take the form of digital cadastral map (DKM) or digitized cadastral maps (KMD). The June 31, 2011 the cadastral sintar map in digital sintar form in 7294 cadastral areas, which is 56% of the total number of 13 027. rest of the Czech Republic is covered with analog cadastral sintar map drawn on a plastic film which is available for scanning in raster format.
The accuracy sintar of the cadastral maps according to Decree No. 26 / 2007sb. as amended determined by the scale at which the map is displayed, respectively, from which the map is digitized. sintar For maps DKM is precision drawings, respectively. break points parcel boundaries, established the basic mean coordinate error of 14 cm. The digitized map of the original scale of 1: 1000 fracture points are the mean coordinate error of 0.21 m, scale 1: 2000 - 0.50 mau scale of 1: 2,880 points have a fracture accuracy of 1,00 m. From which one can calculate the margin of error, which is within the accuracy of the maps and tolerable and maybe it is for the map at a scale of 1: 2.83 meters in 2880.
