Natura 2000 2018

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 Natura2000 product must be in a geodatabase (gdb), GeoPackage (gpkg), FlatGeobuf (fgb) or GeoParquet (parquet) format.

Naming convention:

The layer name must match regex:

^n2k_du[0-9]{3}[a-z]_Status2018_lclu_v[0-9]+_[0-9]{8}$

  • the name must start with 'n2k'
  • followed by a delivery unit number which consist of:
    • 'du'
    • 3 numbers [0-9]
    • A letter [a-z]
  • followed by '_Status2018'
  • followed by '_lclu'
  • followed by a version which consist of:
    • Letter 'v'
    • Followed by numbers
  • the ending must end with a date which consist of 8 numbers signifying the date of delivery (yyyymmdd)

Naming example: N2k_DU001A_Status2018_LCLU_v1_20120530.gdb with a layer named N2k_DU001A_Status2018_LCLU_v1_20120530

Requirements:

Feature satisfying general requirements:
