Virtual Database of Regional Knowledge

Unify the inormation about one particular place


As I have mentioned earlier one of the goal of the Virtual Database of Regional Knowledge (VDRK) could be creation of the database for possibly the smallest area. This area could be an cadaster or plot of land, as per below.

Pic. 9 The satellite imagery with the cadaster and the land lots. Upper part of the image shows also hamlets (marked yellow), that contain at least a dozen or so cadasters and land lots (

The cadasters and land lots are basically the smallest areas, that could be an entry areas at once. We should considerate these areas, when some interesting objects (in any point of view) are situated there. These object can be: a natural monument, landmark, geosites, research areas, sacral buildings etc). Nowadays it works partially. The most interesting places (at least in tourism) has a detailed description unlike to public objects, companies, etc. where is utter lack of informaton (except of the location address). I imagine the role of single plot of land as the place with as much as possible information about.

Going further we are reaching superior areas. A cadaster and land lot will build a hamlet (village) or a subdivision (city/town). In terms of the hamlet or subdivision the land lots will be a subordinate unit. Having in mind the database creation for superior units we have to take into account the correlation of subordinate units between each other. Threading its way the group of land lots with full information provided will consist of the subdivision/hamlet database.

Next we have a subsequent, bigger units. According to the administrative divisions we have:

  • - quarter (consisted of a few subdivisions),
  • - city/town (consisted of a few districts) or village (consisted of a few hamlets),
  • - municipality (including several villages),
  • - county (including usually a few municipalities),
  • - voivodship (consisted of dozen of ro counties),
  • - country (including at least few voivodships or counties depends on the country),
  • Well, this is the administrative division, however we can make this for another divisions, for instance geographical areas. Is important to have the smallest, entry area to start our job with.

To begin and process our job we need more general information, which will come from bigger, superior areas.

Pic. 10 The information dependancy of the atministrative division.

This bigger area can be the i.e. the voivodship, mountain community, geological unit, vegetation zone or historical area as per below:

  • - The Lesser Poland voivodship lies in the southern part of Poland, thus Cracow lies in southern part of Poland, therefore the Kurdwanów lies in souhern Poland also,
  • - The Makowski Beskid Mts lies in western Carpathians, so the Koskowa Mt range lies in western Carpathians and Koskowa Mt lies in western Carpathians too.
  • - The Greater Poland is situated in the tempere climate zone, then Kalisz also is situated in the tempere climate zone.

Sometimes we can face some exceptions. Usually we can know about them from readings.

Having the information about bigger area we are receiving the detailing tools for the information about smaller units. They eventually will come back to these final (superior) areas like a boomerang. The simple lot of land or cadaster cannot influence so much on the county or voivodship. Hence the arrows in the image above are headed towards the closest superior areas.

Gathering the information for Regional Virtual Database could have the boomerang feature. Organising the data for the smallest units cound not be possible without some information coming from the highest units. At the outcome these the most superior areas could get much more information from all inferior units included.
