// Create map
var layer = L.leafletGeotiff(url, options).addTo(map);
Parameters:
url
- GeoTIFF file URL. Currently only EPSG:4326 files are supported.options
:
bounds
- (optional) An array specifying the corners of the data, e.g. [[40.712216, -74.22655], [40.773941, -74.12544]]. If omitted the image bounds will be read from the geoTIFF file.band
- (optional, default = 0) geoTIFF band to read.image
- (optional, default = 0) geoTIFF image to read.clip
- (optional, default = undefined) Clipping polygon, provided as an array of [lat,lon] coordinates. Note that this is the Leaflet [lat,lon] convention, not geoJSON [lon,lat].renderer
- Renderer to use (see below).Raster data rendered using Plotty: L.LeafletGeotiff.plotty(options)
Options:
displayMin
- (optional, default = 0) Minimum values to plot.displayMax
- (optional, default = 1) Maximum values to plot.clampLow
, clampHigh
- (optional, default = true) If true values outside displayMin
to displayMax
will be rendered as if they were valid values.colorScale
- (optional, default = "viridis"). Plotty color scale used to render the image.New color scales can be created using plotty's addColorScale
method.
Vector data rendered as arrows: L.LeafletGeotiff.vectorArrows(options)
Options:
arrowSize
- (optional, default = 20) Size in pixels of direction arrows for vector data.getValueAtLatLng(lat,lng)
