read_asc: Read asc files

In brry/mhmVis: Visualisation of 'mHM' Input and Output Files, Including 'netcdf' Files

Description

Read mHM-typical ASC raster files and create a full set of (projected) coordinates

Usage

read_asc(file = file.choose(), proj = NA, ...)

Arguments

file	Name of file. DEFAULT: file.choose()
proj	Current projection string or NA. If not NA, coordinates will be converted to lat-long coordinates. If proj is a number, e.g. 3035, it will be replaced with the online epsg proj4 from http://www.spatialreference.org/ref/epsg/3035/. Note that setting proj may increase computing time a lot. proj is passed as the from argument to OSMscale::projectPoints. DEFAULT: NA
...	Further arguments passed to read.table

Value

Invisible list with matrices for "asc", "x" and "y", as well as character strings for the filename ("file" and "name"), and the projection ("proj"). There are also values for the NA character string ("NAS") and "cellsize", as well as the metainformation lines from the file ("meta").
#' x and y are original coordinates, unless proj != NA, in which case they are transformed to lat-long degrees.
