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.

Naming convention:

If the delivery is in Geopackage format, filename must match pattern:

+-- clms_ua_lcu_s2024_v025ha_<FUAcode>_<FUAname>_<EPSGcode>_<version>_<revision>_<release_date>.gpkg     (Geopackage name),      e.g.: CLMS_UA_LCU_S2024_V025ha_PL027L2_KALISZ_03035_V01_R00_20240212.gpkg
    +-- clms_ua_lcu_s2024_v025ha_<FUAcode>_<FUAname>_<EPSGcode>_<version>_<revision>_<release_date>      (Layer name),           e.g.: CLMS_UA_LCU_S2024_V025ha_PL027L2_KALISZ_03035_V01_R00_20240212

If the delivery is in Geodatabase format, filename must match pattern:

+-- clms_ua_lcu_s2024_v025ha_<FUAcode>_<FUAname>_<EPSGcode>_<version>_<revision>_<release_date>.gdb/      (Geodatabase name),      e.g.: CLMS_UA_LCU_S2024_V025ha_PL027L2_KALISZ_03035_V01_R00_20240212.gdb/
    +-- clms_ua_lcu_s2024_v025ha_<FUAcode>_<FUAname>_<EPSGcode>_<version>_<revision>_<release_date>/      (Feature dataset name),  e.g.: CLMS_UA_LCU_S2024_V025ha_PL027L2_KALISZ_03035_V01_R00_20240212
        +-- clms_ua_lcu_s2024_v025ha_<FUAcode>_<FUAname>_<EPSGcode>_<version>_<revision>_<release_date>   (Feature class name),    e.g.: CLMS_UA_LCU_S2024_V025ha_PL027L2_KALISZ_03035_V01_R00_20240212
where
  • <FUAcode> is the code of the functional urban area;
  • <FUAname> is the name of the functional urban area; If the name has multiple words they must be separated by hyphen e.g REGGIO-DI-CALABRIA
  • <EPSGcode> is the EPSG code of the required coordinate system;
  • <version> is the major release version code;
  • <revision> is the code of revised release;
