`mregions` - Get data from <https://www.marineregions.org>
Some data comes from the [Flanders Marine Institute (VLIZ) geoserver](http://geo.vliz.be/geoserver/web/)
`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 (<https://www.obis.org>))
* Geocode - get geolocation data from place names
* Reverse Geocode - get place names from geolocation data
## Install
```{r eval=FALSE}
install.packages("mregions")
install.packages("sf")
```
Development version
```{r eval=FALSE}
devtools::install_github("ropensci/mregions")
```
Load Libraries
```{r}
library("mregions")
library("sf")
# helper library
library("leaflet")
```
## Get GeoJSON
#### example 1: Marine Ecoregions of the World (MEOW)
**Get Data**
Keys accessible from the [Flanders Marine Institute (VLIZ) geoserver](http://geo.vliz.be/geoserver/web/).
```{r, eval=TRUE}
ecoregions_geoJSON <- mr_geojson(key = "Ecoregions:ecoregions", maxFeatures = 250)
length(ecoregions_geoJSON$features)
```
**Plot Data**
```{r eval=FALSE}
leaflet() %>%
addProviderTiles(provider = 'OpenStreetMap') %>%
addGeoJSON(geojson = ecoregions_geoJSON$features) %>%
fitBounds(-160,-52,160,60)
```
### example 2: Maritime Boundaries (EEZ)
**Get Data**
```{r}
eezboundaries_geoJSON <- mr_geojson(key = "MarineRegions:eez", maxFeatures = 1)
```
**Plot Data**
```{r eval=FALSE}
leaflet() %>%
addProviderTiles(provider = 'OpenStreetMap') %>%
addGeoJSON(geojson = eezboundaries_geoJSON$features) %>%
fitBounds(39,11,83,-10)
```
## Get Shape
#### example 1: Marine Ecoregions of the World (MEOW)
**Select region**
```{r, eval=TRUE}
ecoregions_shp <- mr_shp(key = "Ecoregions:ecoregions", maxFeatures = 250)
class(ecoregions_shp)
```
**Plot data**
```{r eval=FALSE}
leaflet() %>%
addProviderTiles(provider = 'OpenStreetMap') %>%
addPolygons(data = ecoregions_shp)%>%
fitBounds(-182,-79,178,83)
```
#### example 2: Maritime Boundaries (EEZ)
**Select region**
```{r, eval=FALSE}
eezboundaries_shp <- mr_shp(key = "MarineRegions:eez", maxFeatures = 1)
```
**Plot data**
```{r eval=FALSE}
leaflet() %>%
addProviderTiles(provider = 'OpenStreetMap') %>%
addPolygons(data = eezboundaries_shp)
```
## Convert to WKT
#### example 1: Marine Ecoregions of the World (MEOW)
**From GeoJSON**
```{r eval=TRUE}
ecoregions_geoJSON <- mr_geojson(key = "Ecoregions:ecoregions", maxFeatures = 250)
ecoregions_wkt_fromGeoJSON <- mr_as_wkt(ecoregions_geoJSON, fmt = 2)
class(ecoregions_wkt_fromGeoJSON)
ecoregions_wkt_fromGeoJSON[1]
```
**From shp object (using the sf package)**
```{r eval=TRUE}
ecoregions_shp <- mr_shp(key = "Ecoregions:ecoregions", maxFeatures = 250)
ecoregions_shp_geom <- st_geometry(ecoregions_shp)
ecoregions_wkt_fromshp <- st_as_text(ecoregions_shp_geom)
ecoregions_wkt_fromshp[1]
```
*More detailed example using the Black Sea Ecoregion only*
```{r, eval=TRUE}
ecoregions_blacksea <- subset(ecoregions_shp, ecoregions_shp$ecoregion == "Black Sea")
class(ecoregions_blacksea)
ecoregions_blacksea_geom <- st_geometry(ecoregions_blacksea)
class(ecoregions_blacksea_geom)
ecoregions_blacksea_wkt <- st_as_text(ecoregions_blacksea_geom)
class(ecoregions_blacksea_wkt)
ecoregions_blacksea_wkt
```
## Gazetteer Record by Name
#### example: High Seas
```{r, eval=TRUE}
highseas_info <- mr_geo_code(place = "High Seas")
class(highseas_info)
str(highseas_info)
```
