imageJ.to.lxly: Convert map pixels from digitzing program to plot...

In forestgeo/ctfs: Tools for the Analysis of Forest Dynamics

Description

Convert map pixels from digitzing program to plot coordinates. Uses 2 functions from geometry.r: pts.to.interceptslope=function(pt1,pt2) perpendicular.distance=function(b,m,x,y) return(sqrt((y-m*x-b)^2/(1+m^2))) intersection.of.lines=function(b1,m1,b2,m2)

Usage

imageJ.to.lxly(textfile = samplemapfile, delim = ",",
  lowerleft = "P2", upperleft = "P1", upperright = "P4",
  lowerright = "P3", gridsize = c(20, 20))

Arguments

textfile	the complete name of the textfile to convert, including the path
delim	the delimiter used to separate the fields in the map files
lowerleft, upperleft, upperright, lowerright	the tags in each of the map files with the calibrated corners
gridsize	Size of each individual map.
