CatastRo

CatastRo provides access to services from the Spanish Cadastre. With CatastRo, you can download buildings, cadastral parcels, addresses and map imagery, geocode cadastral references and look up cadastral references from coordinates.

Installation

Install CatastRo from CRAN:

install.packages("CatastRo")

Check the documentation for the development version at https://ropenspain.github.io/CatastRo/dev/.

You can install the development version of CatastRo from r-universe:

# Install CatastRo in R.
install.packages(
  "CatastRo",
  repos = c(
    "https://ropenspain.r-universe.dev",
    "https://cloud.r-project.org"
  )
)

Alternatively, you can install the development version of CatastRo with:

pak::pak("rOpenSpain/CatastRo")

[!WARNING]

SSL issues

The SSL certificate of the Spanish Cadastre may cause an error when using CatastRo (especially on macOS, see issue #40):

In CatastRo >= 1.0.0, you can try to fix it by running this line after loading the package:

# Disable SSL verification
options(catastro_ssl_verify = 0)

If you wish to make this setup persistent, write the same code in your .Rprofile:

# ... other options...
options(catastro_ssl_verify = 0)

Modify your .Rprofile with usethis::edit_r_profile().

Package API

The functions of CatastRo are organized by source service. The package naming convention is catr_*service*_*description*.

OVC services

OVC services cover geocoding and reverse geocoding with OVCCoordenadas, and province and municipality code lookup with OVCCallejero.

These functions use the catr_ovc_get_*() prefix and return tibbles from the tibble package. See vignette("ovcservice", package = "CatastRo") for a detailed description of these functions.

INSPIRE

INSPIRE functions return spatial objects from the Spanish Cadastre INSPIRE services using the sf or terra packages.

Note that these services cover 95% of the Spanish territory, excluding the Basque Country and Navarre¹, which have their own independent cadastral offices.

There are three types of functions, each querying a different service:

ATOM service

The ATOM service downloads complete municipal datasets for different cadastral elements. Results are returned as sf objects from the sf package.

These functions use the catr_atom_get_*() prefix.

WFS service

The WFS service downloads vector objects for specific cadastral elements. Results are returned as sf objects from the sf package. Note that there are restrictions on the extent and number of elements that can be queried. For full municipal downloads, prefer the ATOM service.

These functions use the catr_wfs_get_*() prefix.

WMS service

The WMS service downloads georeferenced map images for different cadastral elements. Results are returned as SpatRaster objects from the terra package.

There is a single function for querying this service: catr_wms_get_layer().

Terms and conditions of use

Please check the service terms of use.

Examples

This script highlights some features of CatastRo:

Geocode a cadastral reference

library(CatastRo)

catr_ovc_get_cpmrc(rc = "13077A01800039")
#> # A tibble: 1 × 10
#>   xcoord ycoord refcat     address pc.pc1 pc.pc2 geo.xcen geo.ycen geo.srs ldt  
#>    <dbl>  <dbl> <chr>      <chr>   <chr>  <chr>  <chr>    <chr>    <chr>   <chr>
#> 1  -3.46   38.6 13077A018… DS DIS… 13077… 18000… -3.4575… 38.6184… EPSG:4… DS D…

Reverse geocode coordinates to a cadastral reference

catr_ovc_get_rccoor(
  lat = 38.6196566583596,
  lon = -3.45624183836806,
  srs = "4230"
)
#> # A tibble: 1 × 8
#>   refcat         address           pc.pc1 pc.pc2 geo.xcen geo.ycen geo.srs ldt  
#>   <chr>          <chr>             <chr>  <chr>     <dbl>    <dbl> <chr>   <chr>
#> 1 13077A01800039 DS DISEMINADO  P… 13077… 18000…    -3.46     38.6 EPSG:4… DS D…

Extract geometries using the ATOM service

bu <- catr_atom_get_buildings("Nava de la Asuncion", to = "Segovia")

# Map.
library(ggplot2)

ggplot(bu) +
  geom_sf(aes(fill = currentUse), col = NA) +
  coord_sf(
    xlim = c(374500, 375500),
    ylim = c(4556500, 4557500)
  ) +
  scale_fill_manual(values = hcl.colors(6, "Dark 3")) +
  theme_minimal() +
  labs(title = "Nava de la Asunción, Segovia")

Extract geometries using the WFS service

wfs_get_buildings <- catr_wfs_get_buildings_bbox(
  c(-4.134, 40.952, -4.131, 40.953),
  srs = 4326
)

# Map.
ggplot(wfs_get_buildings) +
  geom_sf() +
  labs(title = "Alcázar of Segovia, Segovia, Spain")

A note on caching

Some datasets and tiles may exceed 50 MB. You can set a local cache directory using the following function:

catr_set_cache_dir("./path/to/location")

When this option is set, CatastRo looks for cached files and loads them, which speeds up repeated queries.
