基于WebGISGeocoding搜索与Lambert变换的研究与实现

针对项目平台系统开发中遇到的批量POI（PointofInterest）数据与平台地图进行匹配的问题进行分析与研究．通过地理编码对经纬度进行搜索，并建立经纬度与Lambert投影变换的数据模型。运用C#语言进行实现验证，并完成批处理经纬度搜索与投影变换的功能。最终将覆盖全国范围内所有POI坐标数据与平台地图成功匹配，满足了项目的需求，也使平台开发的功能得以进一步加强，为平台支持多分辨率、多尺度、多投影的全球空间数据提供了技术积累。

Research and Implementation of Geocoding Searching and Lambert Projection Transformation Based On WebGIS

This paper mainly do some research and analysis on the issue generated by the spatial coordinate system transformation, which encountered in trying to match POI data and the map data during the implementation of the platform for our project. Through the search of latitude and longitude of geocoding, established the conversion model between latitude、longitude data and Lambert projection, then use C # language to implement it, finally achieved the transformation of coordinate system's projection in batch. POI data was eventually coordinated with the platform map coordinate successfully. This work not only met the needs of the project, but also strengthened the function of platform. Do some technical accumulations for the supporting of multi-resolution, multi-scale, multi-projection of the world's space.
