Filter Tiled Layers
One of the core ideas in mapping is the difference between vector and raster layers. For vector layers, the actual geometry data is stored and passed around - for example a point might store the latitude and longitude. For tiled raster layers, the data is stored as images on the server, and those images are displayed as the layer.
In the past, the visualization of tiled raster layers could not be filtered based on geometry. Using layer blending in recent versions of the ArcGIS Maps SDK for JavaScript, this is now possible.
Using the WGS 84 Coordinate System in ArcGIS JavaScript Maps
Web Mercator is the standard for online interactive maps. But what if we want to use the EPSG 4326 (WGS 84) spatial reference?
