Try MapCalc. Want to learn more? MapInfo MIG modeling technique as related to up-slope buffering for pioneer road safety is outlined by BASIS at:
http://www.innovativegis.com/basis/Senarios/Roadbuff_scenario.htm Via MIG and other like file formats you can create the variable width buffers based on adjacent slopes. Flat smooth stream areas many not need the same buffering as areas where the stream is running in rapids. Same goes for a stream that has cut in to the side of the flood plain valley. Its adjacent topography has one generally very steep side and the other gently sloping to level on the floodplain side that can meander through the landscape.

The MI buffer tool uses a (cartesian) horizontal radius (X,Y to X1,Y1 = 50m). The spherical selection does not use local elevation data. Has anyone used elevation or slope distance (X,Y,Z TO X1,Y1,Z1 = 50m) to create a buffer? I will most likely use the concentric ring buffer as I will have to create more than 1 buffer. Any advice would be great... Thanks... Randy G.
