Projection

Most mapping projections are handled automatically by SpatialReferences built into basemaps, feature layers, and graphics. However, there is also a tool you can call directly to "Project" or "GetTransformation" between several different SpatialReferences. In this sample, the maps are auto-calculating the projections, but the X/Y coordinates and GeographicTransformation steps are calculated via the projection tool. See the Source Code for the Display Projection page for more Wkid values. Not all values will render properly with this GeoJSON map.
