Do you have any type of mobile SDK that allows for indoor mapping? I guess I am looking for an SDK that allows me to draw a bitmap as the basemap layer and draw vector graphics on top to annotate it. Normal ESRI operation would allow me to draw a raster layer, but I think that has to be a GeoTiff for proper placement in the spatial reference. I want something that doesn't necessarily relate to the globe, but just an arbitrary X,Y coordinate system.
