摘要
以东山赤山国有防护林场大帽山工区矢量图和卫片图配准为例,介绍了以VIEWGIS和GOODYGIS软件为工具配准林业小班矢量图和卫片图形成复合图的方法和步骤,并分析了配准可能产生的误差及其在林业中的应用。实验表明采用这种方法配准矢量图和卫片图速度快、精度高、易于更新。
With vector chart and satellite image of Damaoshan work area as the case, a compound map making use of vector graph and satellite image based on VIEWGIS and GOODYGIS were developed step by step. Errors of geo--referencing and the map application to forestry were discussed. The ex- periment results showed that the method of georeferencing vector graph and satellite image is effi- cient, accurate and easy to update.
