| 摘 要： | 针对MAPGIS非标准制图过程中, 多景多区域原参数非同一的图件拼接, 文件合并过程中易产生的图元、 信息混乱等问题, 根据MAPGIS的整图变换、 地图参数、 图元实际大小的特性, 推导并结合3个参量的关系, 进行参量统改, 实现了多景多区域原参数非同一图件的归一化处理, 得到了投影类型、 比例尺、 地图参数等关键参数统一的图件。提高了非标准图件的制作效率, 为非标准图件标准化提供了方法指导。

| Abstract: | When several non-standard maps are joined together and the geographic files are combined, the graph parameters will be changed to make pixel disordered. To solve the problem mentioned above, the paper seeks the characteristics of map transformation, graph parameters as well as pixel size, and analyzes their relationship to achieve the parameter's correction. Eventually, it fulfills the normalization and obtains the sheet which has uniform original parameter's including the projection, type plotting scale and map parameter. The work in this paper provides method instruction for non-standard sheet's standardizationand improves the efficiency of non-standard sheet's making. |
