The simplegeom
class represents geometries that can
be coerced into polygon features. This is one of two stencil
types
accepted by geoknife
(the other being webgeom).
sf
an sf data.frame object with polygon geometries
sp
an sp object provided for backward compatibility
DRAW_NAMESPACE
(_private) web location of draw namespace
DRAW_SCHEMA
(_private) web location of draw schema
The difference between webgeom and simplegeom
is both in the permanence and the location of the data. webgeom is
located on a web server that offers geometries using the web feature service (WFS)
specification. simplegeom are typically local data that can be accessed
within an R session. Within reason, anything that can be represented as a
webgeom (or WFS) can also be represented by a simplegeom
For example, a state or watershed can be read in as read_sf
object and turned into a simplegeom. IDs of a web geom are the
row order of the geometries.
