Interactive viewing of spatial data in R
mapview provides functions to very quickly and conveniently create
interactive visualisations of spatial data. It’s main goal is to fill
the gap of quick (not presentation grade) interactive plotting to
examine and visually investigate both aspects of spatial data, the
geometries and their attributes. It can also be considered a data-driven
API for the leaflet
package as it will automatically render correct map types, depending on
the type of the data (points, lines, polygons, raster). In addition, it
makes use of some advanced rendering functionality that will enable
viewing of much larger data than is possible with leaflet.
Furthermore, if you’re a fan of
mapdeck (which you
should!), you can choose to use it as the rendering platform instead of
leaflet by setting
mapviewOptions(platform = "mapdeck").
The main user relevant functions are:
mapview- view (multiple) spatial objects on a set of background maps
viewExtent- view extent / bounding box of spatial objects
viewRGB- view RGB true- or false-color images of raster objects
mapshot- easily save maps (including leaflet maps) as
png(or other image formats)

For CRAN release version of mapview use
To install the development version you can install the remotes package.
NOTE: As of version 2.9.1 development will happen on the
branch. Please consider the
develop branch obsolete.
The most basic call
will produce a web map visualisation of the breweries data with the following components:
