mregions

mregions - Get data from http://www.marineregions.org

Some data comes from the Flanders Marine Institute (VLIZ) geoserver

mregions is useful to a wide diversity of R users because you get access to all of the data MarineRegions has, which can help in a variety of use cases:

• Visualize marine regions alone
• Visualize marine regions with associated data paired with analysis
• Use marine region geospatial boundaries to query data providers (e.g., OBIS (http://www.iobis.org))
• Geocode - get geolocation data from place names
• Reverse Geocode - get place names from geolocation data

Install

install.packages("mregions")

Development version

devtools::install_github("ropenscilabs/mregions")

library("mregions")

GeoJSON

Get region

res1 <- mr_geojson(key = "Morocco:dam")

Get helper library

install.packages("leaflet")

Plot data

library('leaflet')
leaflet() %>%
  addProviderTiles(provider = 'OpenStreetMap') %>%
  addGeoJSON(geojson = res1$features) %>%
  setView(-3.9, 35, zoom = 10)

Shape

Get region

res2 <- mr_shp(key = "MarineRegions:eez_iho_union_v2", maxFeatures = 5)

Get helper library

install.packages("leaflet")

Plot data

library('leaflet')
leaflet() %>%
  addProviderTiles(provider = 'OpenStreetMap') %>%
  addPolygons(data = res2)

Convert to WKT

From geojson

res3 <- mr_geojson(key = "Morocco:dam")
mr_as_wkt(res3, fmt = 5)

#> [1] "MULTIPOLYGON (((41.573732 -1.659444, 45.891882 ... cutoff

From shp object (SpatialPolygonsDataFrame) or file, both work

mr_as_wkt(mr_shp(key = "MarineRegions:eez_iho_union_v2"))

#> [1] "GEOMETRYCOLLECTION (POLYGON ((-7.25 ... cutoff

Get OBIS EEZ ID

mr_obis_eez_id("bulgarian exclusive economic zone")
