HOW TO GEOLOCALIZE AN ADMINISTRATIVE FILE BASING ON ITS ADDRESSES DATA? A PROPOSAL TO ACHIEVE A BETTER GEOCODING.

摘要: A lot of research works have been devoted to geocoding of postal addresses. The interest in this topic is supported by the need to transform postal addresses into geographical coordinates which are essential for various domains of scientific and social research. The benefits of the address geocoding precision are numerous. Geocoding can be used for a wide range of applications such as market segmentation, demographics, geo-spatial distribution of plants, sales territories, taxes, elections. Geocoding is also a very important tool to target certain demographics characteristic. The results of geo-coding have provided fundamental components for wide variety of research works in many fields (eg health [4], crime analysis [8], political science [5], computer science [7], etc.). The geocoding operation plays for example an important role for marketing in companies; it helps to cluster peoples with specific characteristics that might be interested in their products.Many research centre and companies have developed free and commercial geocoder. A big number of these softwares use the linear interpolation method to calculate the spatial coordinates. This method estimates the coordinates of an address using the coordinates of bordering addresses of the street where the address is located. Many research papers [1],[7] have described the error in localization produced by using the linear interpolation method. It was mentioned in [1] that the error in localization can reach 3 kilometres (the distance between the true position and the estimated localization). In addition to the localization error, a big number of the developed tools do not take into account …
