Profile Marker Pro 5．0是由Cratag Macbeth公司 生产的色彩管理工具包,它由测量仪器及相应的多 种软件组成,可以运行于Macitosh(苹果机)与Windows (PC机)等多种操作系统之中。 全部软、硬件都封装在一个硬纸盒中,其中包 括两张光盘、两本极其简单的操作指导、保修单、厂 方领导亲笔签署的合格证及全部硬件(图1)。
Topology is normally considered as independent of shape of spatial objects. This may not necessarily be true in describing relations between spatial objects in GIS. In this paper, we present proof tha
An architecture introducing wireless relaying technologies into the cellular infrastructure has emerged as an approach to enlarge the coverage area and enhance system capacity. In this paper, a two-ho
The purpose of reverse engineering is to convert a large point cloud into a CAD model. In reverse engineering, the key issue is segmentation, i.e. studying how to subdivide the point cloud into smalle
黑龙江省测绘学会第一次会员代表大会于1965年11月22日-12月3日召开，标志着黑龙江省测绘学会正式成立。本学会是经黑龙江省社团管理部门批准成立的全省测绘科技工作者的群众性学术团体，是黑龙江省科学技术协会的组成部分，也是中国测绘学会的组成部分。黑龙江省测绘学会挂靠在黑龙江省测绘局，常设机构是黑龙江省测绘学会办公室，下设科技期刊《地理信息世界》、《测绘与空间地理信息》编辑部2个。主要开展学术交流、
