mapview

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 html and/or png (or other image formats)

Functions that have been deprecated/deleted recently:

  • addHomeButton - deprecated, use package leafem instead.
  • addLogo - deprecated, use package leafem instead.
  • addFeatures - deprecated, use package leafem instead.
  • addMouseCoordinates - deprecated, use package leafem instead.
  • addExtent - deprecated, use package leafem instead.
  • addImageQuery - deprecated, use package leafem instead.
  • latticeView & sync - deprecated, use package leafsync instead.
  • slideView - deprecated, use package slideview instead.
  • cubeView - deprecated, use package cubeview instead.
  • plainview - deprecated, use package plainview instead.
  • popupTable, popupGraph & popupImage - deprecated, use package leafpop instead.
  • addLargeFeatures - use leafgl::addGL* functions instead.

Objects of the following spatial classes are supported:

  • sf
  • raster (Layer, Stack, Brick and SpatialPixels* / SpatialGridDataFrame)
  • stars
  • sp (Points, Polygons, Lines and their DataFrame version)
  • satellite

Installation

For CRAN release version of mapview use

install.packages("mapview")

To install the development version you can install the remotes package.

NOTE: As of version 2.9.1 development will happen on the master branch. Please consider the develop branch obsolete.

remotes::install_github("r-spatial/mapview")

Usage
