确定城市地区人口分布的准确描述，以便制定一个改进的“分母”，对于地理信息系统分析中计算更高精度的比率，特别是在探索疾病的空间动态时，是很重要的。我们没有使用任意行政边界（如人口普查区）汇总的数据，而是开发了基于地籍的专家对称系统（CEDS），这是一种利用辅助信息来划定同质值区域的插值方法。该方法使用地籍数据、土地使用过滤器、专家系统例程建模以及针对各种人口普查枚举单位和其他数据的验证。CEDS方法是通过对纽约市布朗克斯区哮喘住院病例的研究提出的，该研究涉及在主要空气污染源周围建造的邻近缓冲区。使用CEDS的分析表明，由于靠近污染源而导致的哮喘住院风险大于以前使用传统分类方法计算的风险。
Determining in accurate depiction of population distribution for urban areas in order to develop an improved "denominator" is important for the calculation of higher-precision rates in GIS analyses, particularly when exploring the spatial dynamics of disease. Rather than using data aggregated by arbitrary administrative boundaries such as census tracts, we developed the Cadastral-Based Expert Dasymetric System (CEDS), an interpolation method using ancillary information to delineate areas of homogeneous values. This method uses cadastral data, land-use filters, modeling by expert system routines, and validation against various census enumeration units and other data. The CEDS method is presented through a case study of asthma hospitalizations in the borough of the Bronx in New York City, in relation to proximity buffers constructed around major sources of air pollution. The analysis using CEDS shows that asthma hospitalization risk due to proximity to pollution sources is greater than previously calculated using traditional disaggregation methods.
