This product consists of a single change layer.

vector.unzip

Check description: Delivery file can be unzipped.

Required check, the check cannot be skipped.

Check description: Naming is in accord with specification.

Required check, the check cannot be skipped.

Requirements: Each Urban Atlas product must be in a geodatabase (gdb) or GeoPackage (gpkg) format. The geodatabase must contain one feature dataset with one feature class.

Each product also include 2 documents in pdf format:

Naming convention:

Optional check, the check may be skipped.

Requirements: All layers of all vector products, feature satisfying general requirements:

Feature is a single-part polygon; a single-part polygon may contain holes but may not contain multiple exterior rings. ;

vector.geometry

Check description: Geometries are valid.

Optional check, the check may be skipped.

Requirements:

Feature satisfying general requirements:

  • Feature with valid geometries as defined by Open Geospatial Consortium’s OpenGIS specification.
  • For each feature with invalid geometry the invalid geometry reason (i. e. self-intersection) and invalid geometry location can be found in the attachment error table.

NOTE: Ring self-intersections while considered valid by ArcGIS are also reported as errors by the QC Tool. ;

vector.area

Check description: Calculated area and value in the column 'area' coincide.

Optional check, the check may be skipped.

Requirements:

  • unit: 1, (value is in m2)
  • tolerance: 0.5 (calculated area and value in the column 'area' do not differ by more than 0.5 m2)

vector.mmu

Check description: Minimum mapping unit.

Optional check, the check may be skipped.

Requirements:

Feature satisfying general requirements:

  • Feature of the class 1 in the final year having area >= 1000 m2;
  • Feature of the class 2-5 in the final year having area >= 2500 m2;

Feature satisfying exceptional requirements: * Feature of the class 1.2.2.x in any year; * Feature with one of the following comments in the COMMENT attribute:

Area size exception (at Urban Atlas FUA boundary)
Area size exception (at Urban Atlas FUA boundary); Areas related to boundary update
Area size exception (at Urban Atlas FUA boundary); Areas related to change
Area size exception (inside Urban Atlas FUA boundary)
Area size exception (inside Urban Atlas FUA boundary); Areas related to change

Notes:

  • One feature can have multiple comments in the comment attribute. If a feature has multiple comments, they should be separated by a semicolon (;).

vector.overlap

Check description: No overlapping polygons.

Optional check, the check may be skipped.

Requirements:

There must be no feature having any part of its interior common with any other feature (aka overlaps). ;

vector.neighbour

Check description: No neighbouring polygons with the same code.

Optional check, the check may be skipped.

Requirements:

This check does not apply to features of class 1.2.2.x where neighbouring polygons with the same code are allowed.

  • The requirement level rules are similar to those of reference layer; the only difference is that by the class is actually meant a tuple of initial year class and reference year class. ;
