The sf vignette (https://cran.r-project.org/web/packages/sf/vignettes/sf1.html) lists 7 common ones (Point, Line, Polygon, the "multi" version of those 3, and GeometryCollection) and 10 less common types, many of them including curved lines.
A possible illustration could be based on country maps. Points for locations of cities, multilines for boundaries taken as lines, polygons for the country area, and multipolygon for some countries e.g. archipelagos.
I'm coming to the conversation super late so apologies if this has all already been hashed out.
+1 for the map based illustration!
What do people think of using the formal illustrations just from OGC for intro and a map for summary?
There's a simple example of the OGC illustrations just colourised here
I'm in favor of repurposing existing illustrations wherever possible. @r4space - do you know the licensing information on that image?
New reference after reorganization is at Intro to Vector Data L37.
Since the language on vector standards (as well as more complex vector objects) has been dropped, the existing illustration there now is probably all that is needed.
Agreed. Happy to re-open if there is disagreement.
Episode 1 includes the text:
There is then a place to insert an image. Anyone have an image to illustrate this concept?
