<b>Description</b><br/>A <b>TrackPlan</b> describes either a collection of <b>Track</b>'s that are, or should be, followed when working with a particular <b>ImplementAssembly</b>,  or one or more <b>TrackPattern</b>'s<br/><br/><b>Remark.</b><br/>A <b>TrackPlan</b> can be based on a previously traveled pattern which is stored in the MIS. In that case it has a collection of <b>Track</b> 's. A pattern can also be generated by the farm management system. In that case the <b>TrackPlan</b> also consists of a number of <b>Track</b>'s. <b>Track</b>'s  that are described as a Curve of the <b>LineStringType</b>.<br/><br/>The<b> TrackPlan </b>can also be a collection of TrackPattern's based on <b>GuidanceReferenceLine</b>'s. The <b>TrackPattern</b>'s  specify the distances to the <b>GuidanceReferenceLine</b>'s and the number of parallel <b>Track</b>'s to realize. The computer on the tractor-implement calculates the locations of the <b>Track</b>.<br/><br/><b>Remark.</b><br/>It is the responsibility of the generator of the Track 's to take care that in case of a non straight line described by more then two positions, the angles between the line segments are such that they can be handled by the tractor implement combination.<br/>
