9 November 2021Cadastral parcels are a very important element of spatial knowledge, and therefore a key component of GIS-class Systems.
The purpose of the following article is to gather all essential information about the purposes and ways of using cadastral parcels in the System.
Source of data on cadastral parcels.
Cadastral parcels are part of the Land and Building Registry (EGiB) – a dataset maintained by the County Governor (Starosta), usually “through” the County Center for Geodetic and Cartographic Documentation and surveyors who perform physical measurements in the field.
Since 2019, this dataset—covering geometry (i.e., shape) and parcel numbers—has been available for free to everyone. Counties vary in how they provide access to cadastral source data: from a standard WFS data service to data delivered on a CD after submitting a paper application. You need to call the specific county to find out.
Cadastral parcels in the System.
Use cases of the System related to cadastral parcels:
- I want to check the parcel number where an object is located.
In that case, the easiest way is to add a WMS from the National Land Registry Integration (KIEG) to the System. Unfortunately, it’s only a WMS, so you can only view the data: it cannot be copied, saved, or displayed as a vector layer.
2. I want to search for parcel no. 34/5 within the Złotniki precinct in the Suchy Las municipality.
In this case, you should use the “Cadastral Parcel Search” module (the list of installed modules can be found in the deployment card).
