Riparian Zones (RZ)

Riparian Zones represent transitional areas occurring between land and freshwater ecosystems, characterised by distinctive hydrology, soil and biotic conditions and strongly influenced by the stream water.

Riparian Zones Land Cover/ Land Use layer (rpz layer containing status data for both 2012 and 2018) can be checked by using the QC Tool.

Vector checks

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 Riparian Zone product must be in a geodatabase (gdb), GeoPackage (gpkg) or shapefile (shp) format. The geodatabase must contain one feature dataset with one feature class.

Naming convention:

The filename must match regex:

^rpz_(?P<aoi_code>du[0-9]{3})[a-z]_lclu(?P<reference_year>2012)_v[0-9]{2}$

  • the name must start with ‘rpz_’
  • followed by an AOI code which consists of: Letters ‘du’ followed by 3 numbers
  • followed by ‘_lclu’
  • followed by reference year
  • the name must end with ‘_v’ followed by 2 numbers

The boundary source is: boundary_rpz.shp

Example of filename: rpz_du003_lclu2012_v01.gdb
