The comparison and graphic adjustment of features that cross adjoining map sheets to ensure that the features intersect the boundary at a common, coincident location. A "seamless" database is thereby created.
A procedure to ensure that separate map sheets covering adjacent regions fit exactly along their edges, so that all features crossing sheet lines can be physically joined. In a digital map base, it means that links are established so that the entire set of map sheets link up in a seamless manner.
the comparison and graphic adjustment of features to obtain agreement along the edges of adjoining map sheets.
The process of ensuring that data along the adjacent edges of map sheets matches, i.e. in terms of both position and attributes.
An editing procedure to ensure that all features crossing adjacent map sheets have the same edge locations, attribute descriptions, and feature classes.
An editing procedure to ensure that all features that cross adjacent map sheets have the same edge locations. Links are used when matching features in adjacent coverages.
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.
The GIS or digital map equivalent of matching paper maps along their edges. Features that continue over the edge must be "zipped" together and the edge dissolved. To edge-match, maps must be on the same projection, datum, ellipsoid, and scales and show features captured at the same equivalent scale.
