Line 128: * If the width is greater than 0, but less than 1.5 times the DEM cell size, the four DEM values surrounding the vertex are used. If max or min is specified in the "shape_option" the max or min of the four values is used. If max or min option is not specified (attribute is blank), the average of the four values is used. * If the width is greater than 1.5 times the DEM cell size, at each vertex a buffer region (search radius) is created and all non null DEM values within the buffer object are processed. The diameter of the buffer region is equal to the width specified. If max or min option is not specified, the average of the values within the region is used. These buffer regions are outputted as a separate file, if '''"-check"''' switch is specified in the batch command.<br> If a '''dz''' value is specified ~~(for the 2014-01-AA version or later)~~ this can be used to control the spacing of vertices along the line. If a '''dz''' value of 100 is specified the maximum spacing along the line is 100 (metres or feet), if the existing vertices along the line are greater than 100 (m or ft) apart additional vertices are inserted. The method for inserting additional vertices creates equally spaced vertices. For example, if two vertices along a line are spaced 250m apart and a dz attribute of 100m is specified three line segments of 83.3m will be created as opposed to two segments of 100m and one segment of 50m.<br> '''NOTE:''' For the output GIS file, the '''dz''' attribute is set to 0.0 regardless of the value set in the input field.
