Terrain contour matching, or TERCOM, a navigation system used primarily by cruise missiles. It uses a pre-recorded contour map of the terrain that is compared with measurements made during flight by an on-board radar altimeter.  3, record 1, English, - terrain%20contour%20matching

Edge Matching [is an] important part of the creation of a digital map or GIS database. One digital map may encompass many paper maps, but when the paper maps are laid edge-to-edge, features running across boundaries of the map sheets are not always properly aligned. These misalignments occur for many reasons including survey error, cartographic generalization, and problems of map projection and compilation. Edge matching is a term applied to a variety of techniques employed to resolve these inconsistencies, including warping and rubber sheeting.  4, record 4, English, - edge%20matching

Dead reckoning is a technique of computing the position of a vehicle from its distance and heading measurements. It is an inertial system which uses two independent sensors from which distance and heading information can be extracted. Because each position is relative, cumulative drift errors occur on an average of 2% of the distance traveled. The system consists of a magnetic compass or gyroscope for heading and odometer for distance. Dead reckoning is often combined with map matching to correct for drift errors. It performs well when combined with highly accurate digital maps. It can also be used to back up GPS during satellite visibility outages.  3, record 5, English, - cumulative%20drift
