Adding GeoRegions from Templates

So you have a list of areas that you want to define, but you don't want to enter them in one by one. What to do?### Setup

using GeoRegions

Template GeoRegion Files

Fear not! I have template files that one can use to define RectRegions and PolyRegions. Simply use the templateGeoRegion() to copy the templates into a directory of your choice.

Defining PolyRegions

When defining PolyRegions, the first and last set of (lon,lat) coordinates must be the same (i.e. a closed polygon must be defined)

templateGeoRegion("your-file-path-here")

# GeoRegions.templateGeoRegions — Function.

templateGeoRegions(; path::AbstractString, overwrite::Bool=false)

Copies the template files for defining GeoRegions in textfiles, that can then be added as a batch using addGeoRegions()

Keyword Arguments

• path : The folder to copy the files to

• overwrite : If template files exist in this folder, overwrite?

source

Reading in GeoRegions from a custom file

We can then read in GeoRegions from your custom file using the function addGeoRegions(), which will then read all the GeoRegion information in the file and add it to the list of GeoRegions.

addGeoRegions("recttest.txt")
GeoRegion("TRP")

The Rectilinear Region TRP has the following properties:
    Region ID    (ID) : TRP
    Parent ID   (pID) : GLB
    Name      (name)  : Tropical
    Bounds  (N,S,E,W) : [30.0, -30.0, 360.0, 0.0]
        (is180,is360) : (false, true)

# GeoRegions.addGeoRegions — Function.

addGeoRegions(fname::AbstractString)

Extracts information of the GeoRegion with the ID RegID. If no GeoRegion with this ID exists, an error is thrown.

Arguments

• fname : name + path of the file containing GeoRegion information

Reset the list of GeoRegions

Should one wish to entirely reset the list of GeoRegions, one can call resetGeoRegions():

resetGeoRegions()

resetGeoRegions(allfiles=true)

# GeoRegions.resetGeoRegions — Function.

resetGeoRegions(; allfiles::Bool = false)

Reset all the files containing GeoRegion information back to the default.

Arguments

• allfiles : If true, reset the GeoRegions defined in Giorgi & Francisco [2000], AR6 Regions (Iturbide et al., 2020; ESSD) and Seneviratne et al. [2012] as well. If false, only reset the custom GeoRegions.
