建立森林资源地理信息系统数据采集方法初探

【摘要】 以江淮地区低丘巢湖佛岭林场森林资源地理信息系统的建立为例 ,提出一种综合利用Photoshop图像处理技术对卫片进行扫描、拼接 ,利用 View GIS软件的颜色识别系统进行森林类型判读 ,利用 GPS采点对判读精度进行估计的方法采集数据 ,并对此方法的投资及其效果进行了分析 ,认为此法可在林业基层生产单位进行推广更多还原

【Abstract】 Based on the establishing forest recources GIS of Chaohu FuLing forestry center—it lies in the areas of JiangHuai and belongs to low lands—advanced a method of acquiring geography data that integrated utilizing the Photoshop image processing technique to scan satellite image and put them together and utilizing the color identifying system of thd ViewGIS software to decipher the forest styles and utilizing GPS to gather data for estimating the deciphering precision,and analyzed the investment and the effecting,and considered it may extend to forest basic level manufacture units.更多还原
