Edge Matching
Edge matching is simply the procedure to adjust the position of features that extend across typical map sheet boundaries. Theoretically data from adjacent map sheets should meet precisely at map edges.
edge matching : An editing procedure to ensure that all features that cross adjacent map sheets have the same edge locations.

Edge Matching is an important part of the creation of a digital map or GIS database. One digital map may encompass many paper maps.
Edge Matching
A situation worth noting in regard to map projections, and their properties, is the edge matching of adjacent regions.
Edge matching is a procedure to adjust the position of features extending across map sheet boundaries. This function ensures that all features that cross adjacent map sheets have the same edge locations.
Edge matching: DEM datasets within a project area (consisting of a number of adjacent files) are edge matched to assure terrain surface continuity between files. Edge matching is the process of correcting adjacent elevation values along common edges.
Edge matching - The process of matching corresponding features across map boundaries. This is a prerequisite for using multiple digital maps in geographic data processing and analysis.

Edge Matching: The process of ensuring that data along the adjacent edges of map sheets or some other unit of storage, matches in both positional and attribute terms.
Because of excellent edge matching efforts, this mosaic shows little blockiness or variations in tone within each image component nor any discontinuities at the margin.
[LINK] Each scale reduction required edge matching, or paneling, of the larger scale maps to produce the next small scale map.

Data corrections were made in the NED assembly process to minimize artifacts, permit edge matching, and fill sliver areas of missing data. This focus piece explores the who, what and where of the NED.
Aronoff (1989) described seven maintenance and analysis functions for spatial data: format transformation, geometric transformation, transformation between map projections, conflation, edge matching, editing of graphic elements, ...
More LSQR interpolations would probably have helped in this case. However, the edge matching problem highlights a key weakness of the interpolative approach taken up until now, which prompted me to add a different patching strategy to BLACKART.
