slippySpatial: Spatial Layer Slippy Map Generation

In ozjimbob/Rslippy: Slippy tile map generation for spatial objects

Description

Generates tiles and a tile-based slippy map based on the Leaflet Javascript library, from a Spatial class object. At the moment it's only tested on SpatialPolygons, especially for the plotting options

Usage

slippySpatial(sp, zoom = c(3, 9), output, col = "white", border = "black", browse = TRUE)

Arguments

sp	A Spatial* class object.
zoom	A vector with the minimum and maximum zoom levels to be rendered.
output	Map output location.
col	Fill colour of polygons, can be a vector.
border	Border colour of polygons, can be a vector.
browse	Launch a browser to display the map when complete.

Details

Currently renders a Spatial object to tiles, produces the HTML/Javascript code to display it. No projection of raster into the correct coordinate system currently takes place, so geographic WGS84 rasters are required. Note that there is a web Mercator error at small scales that I'm working on fixing.

Value

Launches a browser window displaying the map, and returns the location of the index.html file.
