Example

from ipyleaflet import Map, ImageService, basemaps

im = ImageService(
    url='https://landsat.arcgis.com/arcgis/rest/services/Landsat/PS/ImageServer',
    rendering_rule={"rasterFunction":"Pansharpened Enhanced with DRA"},
    format='jpgpng',
    attribution='United States Geological Survey (USGS), National Aeronautics and Space Administration (NASA)'
)

m = Map(basemap=basemaps.Esri.WorldTopoMap, center=(47.655548, -122.303200), zoom=12)

m.add(im)

m

Usage

By default, options like format, band_ids, time, rendering_rule are appended to the request URL when making the image service layer request.
