This work defines a corridor rendering algorithm with variable leg buffer distances and the algorithm also supports geographic world model. A corridor is defined by a path and two distances for each leg to make a buffered zone around the path. Rendering of a corridor is a challenging task in GIS applications. Corridor is extensively used on mission computer displays on command and control platforms and civilian air control centers. Line buffering [1] and offset curve [2] approximations are the special case for the corridor in which there is a constant buffer distance for each leg whereas a corridor may have different leg distances. There are various works about line buffering and offset curve approximations but no algorithm is found in literature for corridor problem.
