The layer can have values from following set, the value in brackets is alias to full layer name:

  1. "BODOVE_POLE_B"

  2. "BODOVE_POLE_T"

  3. "BUDOVY_B" ("budovy body")

  4. "BUDOVY_DEF"

  5. "BUDOVY_P" ("budovy")

  6. "DALSI_PRVKY_MAPY_B"

  7. "DALSI_PRVKY_MAPY_L"

  8. "DALSI_PRVKY_MAPY_T"

  9. "HRANICE_PARCEL_L" ("hranice parcel")
