A human engine has a torque curve similar to that of a steam engine, more or less, which is to say that it is flat until a certain critical rpm, at which point it begins to drop off, because the energy used in accelerating and decelerating massy components (legs) begins to take up all the energy produced.

Geospatial Technology July 11, 2008. Raster and vector are two very different but common data formats used to store geospatial data. Vector data use X and Y coordinates to define the locations of points, lines, and areas (polygons) that correspond to map features such as fire hydrants, trails, and parcels. As such, vector data tend to define centers and edges of features. Raster data, on the other hand, use a matrix of square areas to define where features are located.
