Urban Atlas 2018 Street Tree Layer

This product consists of a single status layer.

vector.unzip

Check description: Delivery file can be unzipped.

Required check, the check cannot be skipped.

vector.naming

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), GeoPackage (gpkg), FlatGeobuf (fgb) or GeoParquet (parquet) format. The geodatabase must contain one feature dataset with one feature class.

Each product also include 2 documents in pdf format:

  • Map: name ending with „_map.pdf“
  • Delivery report: name ending with „_delivery_report.pdf“

Naming convention:

The filename without extension must match regex:

(?P<aoi_code>[A-Z]{2}[0-9]{3}L[0-9]{1})_.*_ua2018_stl$

  • the name must start with an 'aoi code' which consists of:
    • 2 letters
    • 3 numbers
    • letter 'L'
    • 1 number
  • the name must end with '_ua2018_stl'

Example of filename: DK001L2_UA2018_stl.gdb``or ``DK001L2_UA2018_stl.gpkg

vector.attribute

Check description: Attribute table check.

Required check, the check cannot be skipped.

Requirements:

Required attributes:
  • “country“: “string“, (length=50), country 2-letter code, e.g. DK
  • “fua_name“: “string“,
  • “fua_code“: “string“,
  • “stl“: “integer“,
  • “perimeter“: “real“,
  • “area“: “real“,

Ignored: “shape_area“, “shape_length“, “geometry_bbox.xmax“, “geometry_bbox.xmin“, “geometry_bbox.ymax“, “geometry_bbox.ymin“

vector.epsg

Check description: CRS (Projection) check.

Required check, the check cannot be skipped.

Requirements:

  • The vector must be assigned spatial reference system EPSG: 3035 (ETRS89 ETRS-LAEA equal-area projection);

vector.import2pg

Check description: Data can be imported into database

Required check, the check cannot be skipped.

vector.inspire

Check description: Metadata.

Optional check, the check may be skipped.

Requirements:

  • All vector deliveries must contain an INSPIRE compliant XML metadata document.
  • Each delivery must contain a 'Metadata' subdirectory with one XML document named <layer_name>.xml where layer_name is the name of the geodatabase or geopackage, e.g.
+-- DK001L2_UA2012.gdb      (Geodatabase name),
+-- Metadata/               (Metadata subfolder),
        +-- DK001L2_UA2012.xml   (INSPIRE XML metadata document)

vector.unique

Check description: Unique attribute check.

Optional check, the check may be skipped.

Requirements: The value in the column 'identifier' must be unique for each input/row (regarding revised, reference and change layers).

Parameters:
  • “unique_keys“: [“identifier“];

vector.enum

Check description: Valid codes.

Optional check, the check may be skipped.

Requirements:

Set of valid codes for stl :

0, 1, 91000, 92000

vector.singlepart

Check description: Singlepart polygon check.

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:

  • mmu: 500 m2

The mmu within the STL layer only apply to polygons with code = 1.

vector.mmw

Check description: Minimum mapping width.

Optional check, the check may be skipped.

Requirements:

Feature satisfying general requirements:

  • Feature of class STL = 0
  • Feature of class STL = 1 having minimum width greater than 10 metres.

Feature satisfying warning requirements:

  • Feature of class STL = 1 having minimum width less than 10 metres.
  • Linear structures (class 1.2.2.x) having a minimum width smaller than 10 m over a distance of up to 50 m. ;

NOTE: The mmw within the STL layer only apply to polygons with code STL = 1.

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:

Feature satisfying general requirements:

  • All neighbouring features have class distinct from the feature in question;
