DESCRIPTION

+Package: osmosm
+Type: Package
+Version: 0.0.1
+Authors@R: c(person("Jean-Marie", "Lepioufle", , "jml@nilu.no", role=c("aut","cre")))
+Title: Osmosm Enables To Get And Manipulate Osm Data
+Description: Quickly get osm data related to a specific place with key features.
+    Manipulate the osm data as subset and augment them by simple modification (rotation, flip,...).
+    The creation of plot of the augmented subset will come soon.
+Depends:
+    R (>= 3.6.3)
+Imports:
+    osmdata,

+## Description
+Quickly get osm data related to a specific place with key features.
+
+- get main features from osm.
+- osm augmentation
+- easy plot (soon)
