Study on Block Segmenting Method of House Number

Abstract

House number is one important city geocoding method, which has the most fundamental positioning role and also is the main information carrier in digital city construction. Because traditional house number system has faultiness and city spatial layout has changed a lot with urbanization process in china, house numbers are chaotic in many cities. It is very inconvenient for city management and information construction. It is urgent to reconstruct scientific house number system. First, the authors introduce the advantages and disadvantages of main domestic and foreign house number systems, analyzed the spatial characters of house number, and compared the merits and demerits of block geocoding and street geocoding method. Then, they point out that street is the appropriate spatial framework for house number system of our country. Next they analyzed the spatial localization characters of the house number geocoding within street framework, and pointed out the shortages of traditional serial number and distance number. Then, they put forward and elaborate the block segmenting method of house number. At last, on the assumption that each block has 100 numbers, the figures of block segmenting are displayed. The block segmenting method can ensure the robustness of house number system. It further strengthens the order and localization role of house number and realizes binding house numbers to street block segment. House numbers will not become chaos with the increases and decreases or changing hands of the buildings in the system.
