关于局(县)大面积、大比例尺森林分布图编绘的原稿图的拼接,在实际工作过程中有不少具体问题,这里想就我个人的一点体会,谈谈原稿图拼接的控制问题。大比例尺森林分布图(我队为林业局、县林业局调查编绘的森林分布图比例尺为1∶5万)是森林调查的重要图面成果资料,因为它是全局(县)范围的全图,而且内容比较完整、比较准确,为掌握林政境界、地形地势、森林分布、交通、居民点与企业现状,总之为指导生产与总体规划工作提供了纵观全局的图纸,所以受到应用单位的欢迎与重视。然而正由于它是局(县) 范围的全图、面积较大,所以在编绘过程中原稿图拼接的控制便是一个重要的问题。因为原稿图的拼接质量不仅关系到成图精度,而且直接关系到界边修
There are quite a few specific problems in the actual working process for the stitching of the original drawings compiled by the bureau (county) large-scale and large-scale forest distribution plots. Here I would like to make a personal experience on how to control the stitching of the original drawings. Large-scale forest distribution map (our team for the Forestry Bureau, County Forestry Bureau survey of forest distribution scale scale 1: 50000) is an important picture of forest survey results information, because it is the whole (county) range of the whole map , And the content is relatively complete and accurate. In order to grasp the state of forest administration, the topography, the distribution of forests, the traffic, the residential areas and the status quo of the enterprises, it provides the overview of the overall plans for the guidance of the production and overall planning and is therefore welcomed by the applicants And attention. However, precisely because it is a full-size map of a bureau (county) area and has a large area, control of stitching the original drawings during the compilation process is an important issue. Because the quality of the stitching of the original figure is not only related to the accuracy of mapping, but also directly related to the border
