ascent

Optional parameter that defines the amount of energy an electric vehicle consumes from increasing elevation (watt-hours per meter). Max value is currently 1000.0 Wh/m and min value is currently 0.0 Wh/m. This is used in conjunction with the descent parameter, as a result both must be supplied when using either optional field. If only one of these parameters is supplied, this is considered an invalid query and will be rejected.
