地址编码是指将地址映射成地理坐标的过程,它提供了一种把描述性地理位置信息转换成GIS地理坐标的方式。本文分析了当前标准规范中的地址编码规则,认为街道与小区等院落实体作为同级别的区域限定物弱化了街道的空间特征,并且在现有地址编码规则基础上提出了将街道前置作为区域限定物的地址编码改进方案;进一步,为了体现街道作为各类地理实体的空间参考基础,本文按照街道的前进方向,定义了在街道线性空间中的地理实体链表组织模型,实现了将相互独立的地址编码实体在街道中的串联组织,从而为今后地址查询中的参考定位提供了模型支持;最后,给出了街道两侧不同类型地理实体纳入街道地址编码实体链表的实例说明。
地阯編碼是指將地阯映射成地理坐標的過程,它提供瞭一種把描述性地理位置信息轉換成GIS地理坐標的方式。本文分析瞭噹前標準規範中的地阯編碼規則,認為街道與小區等院落實體作為同級彆的區域限定物弱化瞭街道的空間特徵,併且在現有地阯編碼規則基礎上提齣瞭將街道前置作為區域限定物的地阯編碼改進方案;進一步,為瞭體現街道作為各類地理實體的空間參攷基礎,本文按照街道的前進方嚮,定義瞭在街道線性空間中的地理實體鏈錶組織模型,實現瞭將相互獨立的地阯編碼實體在街道中的串聯組織,從而為今後地阯查詢中的參攷定位提供瞭模型支持;最後,給齣瞭街道兩側不同類型地理實體納入街道地阯編碼實體鏈錶的實例說明。

Address geocoding is a kind of address matching method based on spatial technique. It is the process of transforming a description of a location, such as coordinates, the address or the name of a place, to a location on the earth’s surface. Address geocoding technologies started late in China, many cities just start capturing the geo coding address data. Many topics need to be explored, such as address code structure and geo coding data management. The authors analyzed the current address geocoding rules. The street is regarded as the same level distinct restriction as the courtyard in the current strardards. At this point they think that the spatial characters of the street are weakened. On the basis of relevant national standards, they put forward the definition amendment of city standard address geocoding. In the amendment, as distinct restriction, street becomes independent and is in front of courtyard. Thus, an entity must belong to one street and the address code must contain the street’s code. Usually it is difficult to do address matching with many types of address data because the address data store in different database tables by the entity types. Using streets as spatial reference system, according to the street onward direction, they well integrate the doorplates, address points and parcels together and put forward the new unified street geocoding model: street address chain model. In this model, geocoding is not simple ad-dress string matching any more, it also makes well use of the streets’direction, parcels’adjacency and other spa-tial characters to assist address geocoding process. This can provide model support for future address matching. The example about street address chain model of address geocoding is given. Predictably, this new address geoc-oding model will improve the match rate and accuracy greatly.
