This paper focuses on the application of triangulation and rubber-sheeting techniques to the problem of merging two digitized map files. The Census Bureau is currently developing a map merging procedure called conflation. Reproducibility, quality control, and a desire for mathematical consistency in conflation lead to a need for well-defined procedures. The Delaunay triangulation is well-define...

One of the difficulties in building consistent databases comes from mismatches between two digital maps. They are caused by the diversity of database providers and the methodology of map production. Rubber sheeting is one of crucial problems in Geographical Information System, which is a mapping procedure to resolve mismatches between two geographical maps representing the same region with a fe...

During rehabilitation of residential buildings built in the first half 20th century, it is necessary to strengthen timber floors so they can fulfill requirements strength and serviceability according contemporary regulations. Floors made monolithic girders be most easily strengthened by forming a composite structure with reinforced concrete slab supported on trapezoidal steel sheeting, appropri...
