Overlapping zoningelements

By Wideke BOERSMA Replies (1)

Dear colleagues, We have the question if zoningelements in the application schema Planned Land Use of the dataspecification Land Use may overlap? In the Netherlands zoning elements can overlap. But in the dataspecification is stated: “A spatial object which is homogeneous regarding the permitted uses of land based on zoning which separate one set of land uses from another.” (p. 67). Herein the words "homogeneous" and "... which separate one set of land uses from another" suggest that ZoningElements do not overlap. That suggestion is also raised by the way in which the data specification describes the concept of "zoning": “The concept of zoning is part of Planned Land Use in many countries. The zoning is composed of polygons that are mutually exclusive. Zoning provides regulation on how LandUse can evolve.” (p. 37). However, these definitions and descriptions are not explicit requirements for a data set. So, how do other Member States deal with this concept? Do you have in your country overlap in zoning elements? And how do you read the dataspecifications about this subject? Is it an explicit requirement or not? Thanks in advance for your responses! Best regards, Wideke Boersma

    Dear Wideke,

    Sorry for the delay in answering.

    I had a look at the Planned Land Use data model, the ATS and the implementation rules (IR) and yes, I agree. I can just find a written description implying this requirement. My experience from regional land use plans in Finland is that zoning element polygons are not supposed to overlap within a plan, but they may do so because of digitalisation errors and due to the fact that some reservations (zoning elements) are digitised as polygons and other as points or lines. I understand it so, that the intention is that zoning elements shouldn't overlap. However, I'd like to interpret it in such a way that that it will not be a requirement of INSPIRE to fix a possible overlap of zoning elements. However, this is just my personal interpretation.

    In Finland most land use reservations (plan markings) that clearly overlap with the zoning elements,  can be considered as supplementary regulations, at least for regional land use plans. One challenge is that INSPIRE only allows zoning elements to be of type MultiGeometry (polygons), while in Finland they may also be points (eg. big complexes for shopping, major industries) or lines (eg. roads) due to scale, which means that we have to map them to supplementary regulation instead.
