eLTER_siteFigure function

eLTER sites managers often want to create figure of the site boundaries.

These R functions allow to create this based on the geographic boundaries entered in DEIMS-SDR as a polygon.

The figure is created with a base map Open Street Map (OSM) (© OpenStreetMap contributors), site boundaries, and title of the site, a resolution of 400px and an PNG extension suitable for both website and publication.

Prerequisites:

In this case some packages must by installed:

jsonlite

install.packages('jsonlite')

Using:

For all eLTER sites the function

sitesNetwork <- getNetworkSites(networkID = 'https://deims.org/api/sites?network=7fef6b73-e5cb-4cd2-b438-ed32eb1504b3')
sitesNetwork <- (sitesNetwork[!grepl('^IT', sitesNetwork$title),])
fProduceMapOfSiteFromDEIMS(
  deimsid = 'https://deims.org/1c9f9148-e8dc-4b67-ac13-ce387c5a6a2f',
  countryCode = 'ITA',
  listOfSites = sitesNetwork,
  gridNx = 0.7,
  gridNy = 0.35,
  width = 0.25,
  height = 0.25,
  siteName = 'Lago Maggiore',
  bboxXMax = 0,
  bboxXMin = 0,
  bboxYMin = 0,
  bboxYMax = 0
)

is accompanied by a evaluation of the country and the figure presents a inset map with relative position of the site in the country:
