mapview is intended to provide a quick and easy way to visualize/plot spatial data in an interactive manner. As such, a one-liner is enough to produce an interactive map view of the data. Methods are defined for all objects from packages sf, sp, raster and satellite.
mapview includes 3 vector type data sets:
breweries- a selection of (micro-) breweries in Franconia, Bavaria.
trails- slected hiking trails in Franconia (not used in this vignette).
franconia- administrative regions of Franconia at the district level.
For vector data a call to
mapview without any further arguments will produce a default map view including:
Here’s an example for each vector type:
If we only want to plot certain columns of the attribute table we can use argument
zcol. Each column will be rendered as a separate layer. These layers will be colored according to the selected attributes.
We can also include legends for the layers. Be careful, though, as it is currently not possible to link legends to layers so we end up with too many legends to fit the viewer window if we want to visualize many layers. This is also the reason why legends are not shown by default.
