Add a Cloud Optimized GeoTIFF layer

Usage

add_cog(
  map,
  url,
  name = "COG",
  bands = NULL,
  colormap = NULL,
  rescale = NULL,
  style = list(),
  visible = TRUE,
  opacity = 1,
  ...
)

Arguments

map: A GeoLibre widget.
url: Public HTTP(S) URL of a Cloud Optimized GeoTIFF or GeoTIFF.
name: Layer name.
bands: Optional one-based band indices. Three or more bands render as RGB; one renders as a single band, which colormap then colors.
colormap: Optional GeoLibre colormap name for single-band rendering.
rescale: Optional list of numeric c(min, max) ranges, one per rendered band. A single c(min, max) pair is accepted for the one-band case.
style: Named list of GeoLibre style overrides such as fillColor, strokeColor, and strokeWidth.
visible: Whether the layer is initially visible.
opacity: Layer opacity from zero to one.
...: Additional style overrides given as named arguments, merged into style. add_geojson(map, data, fillColor = "red") and add_geojson(map, data, style = list(fillColor = "red")) are equivalent.

Value

The modified widget.
