ATOM INSPIRE: Download all the cadastral parcels of a municipality

Description

Get the spatial data of all the cadastral parcels belonging to a single municipality using the INSPIRE ATOM service.

Usage

catrnav_atom_get_parcels(
  munic,
  cache = TRUE,
  update_cache = FALSE,
  cache_dir = NULL,
  verbose = FALSE
)

Arguments

munic

Municipality to extract, It can be a part of a string or the cadastral code. See catrnav_atom_get_parcels_db_all.
cache

A logical whether to do caching. Default is TRUE. See About caching section on catrnav_set_cache_dir().
update_cache

A logical whether to update cache. Default is FALSE. When set to TRUE it would force a fresh download of the source file.
cache_dir

A path to a cache directory. On missing value the function would store the cached files on a temporary dir (See base::tempdir()).
verbose

Logical, displays information. Useful for debugging, default is FALSE.

Value

A sf object.

ATOM INSPIRE: Reference database for ATOM cadastral parcels

Description

Create a database containing the urls provided in the INSPIRE ATOM service for extracting Cadastral Parcels.

Usage

catrnav_atom_get_parcels_db_all(
  cache = TRUE,
  update_cache = FALSE,
  cache_dir = NULL,
  verbose = FALSE
)

Arguments

cache

A logical whether to do caching. Default is TRUE. See About caching section on catrnav_set_cache_dir().
update_cache

A logical whether to update cache. Default is FALSE. When set to TRUE it would force a fresh download of the source file.
cache_dir

A path to a cache directory. On missing value the function would store the cached files on a temporary dir (See base::tempdir()).
verbose

Logical, displays information. Useful for debugging, default is FALSE.

Value

A tibble with the information requested:

  • munic: Name of the municipality.

  • url: url for downloading information of the corresponding municipality.

  • date: Reference date of the data.

Clear your CatastRoNav cache dir

Description

Use this function with caution. This function would clear your cached data and configuration, specifically:

  • Deletes the CatastRoNav config directory (rappdirs::user_config_dir("CatastRoNav", "R")).

  • Deletes the cache_dir directory.

  • Deletes the values on stored on Sys.getenv("CATASTRONAV_CACHE_DIR").

Usage

catrnav_clear_cache(config = FALSE, cached_data = TRUE, verbose = FALSE)

Arguments

config

if TRUE, will delete the configuration folder of CatastRoNav.
cached_data

If this is set to TRUE, it will delete your cache_dir and all its content.
verbose

Logical, displays information. Useful for debugging, default is FALSE.

Details

This is an overkill function that is intended to reset your status as it you would never have installed and/or used CatastRoNav.

Value

Invisible. This function is called for its side effects.

See Also

Other cache utilities: catrnav_set_cache_dir()

Examples

# Don't run this! It would modify your current state
## Not run: 
catrnav_clear_cache(verbose = TRUE)

## End(Not run)

Sys.getenv("CATASTRONAV_CACHE_DIR")

Set your CatastRoNav cache dir

Description

catrnav_set_cache_dir() will store your cache_dir path on your local machine and would load it for future sessions.

Alternatively, you can store the cache_dir manually with the following options:

  • Run Sys.setenv(CATASTRONAV_CACHE_DIR = "cache_dir"). You would need to run this command on each session (Similar to install = FALSE).

  • Write this line on your .Renviron file: CATASTRONAV_CACHE_DIR = "value_for_cache_dir" (same behavior than install = TRUE). This would store your cache_dir permanently.

catrnav_detect_cache_dir() detects and returns the path to your current cache_dir.

Usage

catrnav_set_cache_dir(
  cache_dir,
  overwrite = FALSE,
  install = FALSE,
  verbose = TRUE
)

catrnav_detect_cache_dir(...)

Arguments

cache_dir

A path to a cache directory. On missing value the function would store the cached files on a temporary dir (See base::tempdir()).
overwrite

If this is set to TRUE, it will overwrite an existing CATASTRONAV_CACHE_DIR that you already have in local machine.
install

if TRUE, will install the key in your local machine for use in future sessions. Defaults to FALSE. If cache_dir is FALSE this parameter is set to FALSE automatically.
verbose

Logical, displays information. Useful for debugging, default is FALSE.
...

Ignored

Value

catrnav_set_cache_dir() is called for its side effects, and returns an (invisible) character with the path to your cache_dir.

catrnav_detect_cache_dir() returns the path to the cache_dir used in this session

About caching

Sometimes cached files may be corrupt. On that case, try re-downloading the data setting update_cache = TRUE.

If you experience any problem on download, try to download the corresponding file by any other method and save it on your cache_dir. Use the option verbose = TRUE for debugging the API query.

Download addresses of Navarre in spatial format

Description

Get the spatial data of addresses by bounding box.

Usage

catrnav_wfs_get_address_bbox(x, srs, verbose = FALSE, count = NULL)

Arguments

x

See Details. It could be:

  • A numeric vector of length 4 with the coordinates that defines the bounding box: c(xmin, ymin, xmax, ymax).

  • A sf/sfc object, as provided by the sf package.

srs

SRS/CRS to use on the query. See Details.
verbose

Logical, displays information. Useful for debugging, default is FALSE.
count

integer, indicating the maximum number of features to return. The default value NULL does not pass this parameter to the query, and the maximum number of features would be determined by the default value of the API service (5,000 in this case).

Details

When x is a numeric vector, make sure that the srs matches the coordinate values. Additionally, when the srs correspond to a geographic reference system (4326, 4258), the function queries the bounding box on EPSG:25830 - ETRS89 / UTM zone 30N. The result is provided always in the SRS provided in srs.

When x is a sf object, the value srs is ignored. The query is performed using EPSG:25830 (ETRS89 / UTM zone 30N) and the spatial object is projected back to the SRS of the initial object.

Value

A sf object.
