I drew some lines in a GIS application in this projection:
+proj=longlat+ellps=WGS84 +datum=WGS84 - is there a name for this projection?
I imported my lines into R and to prepare for calculating distance between points on my lines, I projected my lines using:
+proj=laea +lat_0=52 +lon_0=10 +x_0=4321000 +y_0=3210000 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs - again, is there a name for this projection?
To actually calculate distances between points on my lines, I used the
gLength function in the R package
rgeos. What sort of distance calculation does
