7 years ago - in/out extent specification
- graticule across dateline problem
- juggling projection metadata objects
- misunderstandings of source/target, graticule as long/lat, vs. projected
- role of asp/ ratio
- what does the projected end point look like versus 170, 180, -180, -170 etc. (i.e. implicit wrap confusion)
- role of spTransform as a high level on project(xy, inv = TRUE/FALSE)
- the seam in continent at -180/180 (removed with ms_simplify/gUnionCascaded
- North arrows are of limited utility -relationship between plot(extent, asp = 1) and par(mar, xpd)
