1. A method of classifying a mobile device location implemented by one or more processors, a graphics processing unit (GPU), or a combination thereof comprising:

  • storing, by the one or more processors, the GPU, or the combination thereof, a dilated test texture in a GPU frame buffer, the dilated test texture being rasterized mapping information morphologically dilated according to a morphological dilation operation based on an uncertainty estimation associated with the mobile device location;

    mapping, by the one or more processors, the GPU, or the combination thereof the mobile device location to a particular pixel address in the GPU frame buffer associated with the dilated test texture;

    determining, by the one or more processors, the GPU, or the combination thereof, an in-out classification of the mobile device location based on a query of a pixel value associated with the particular pixel address in the GPU frame buffer associated with the dilated test texture; and

    outputting, by the one or more processors, the GPU, or the combination thereof, the in-out classification of the mobile device location.
