Package gp in the OpenCASCADE eryar@163.com China 一.简介 Introduction to Package gp gp是几何处理程序包(Geometric Processor package),简称gp.包gp提供以下功能: 代数计算:如坐标计算.矩阵计算: 基本解析几何元素:如变换.点.矢量.线.面.轴.二次曲线和初等曲面: 这些实体同时在二维和三维空间中定义,且包中的类都是非持续的(non-persistent),即这些类的实例都是以值的方式…
来自:http://zhihu.esrichina.com.cn/?/question/12087 Engine中执行gp工具返回的[解决办法]:需要用gpUtils.DecodeFeatureLayer方法将gp工具生成的图层先读取出来,如: // Intialize the geoprocessor. Geoprocessor GP = new Geoprocessor(); // Intialize the MakeFeatureLayer tool. MakeFeatureLayer m…
原文:ArcGIS API for Silverlight 调用GP服务加载等值线图层 第二篇.Silverlight客户端调用GP服务 利用ArcGIS API for Silverlight实现GP服务调用,这里的雨量数据是通过一个WebService获取而来,主要信息是雨量站点的经纬度坐标值和某个时间段内的降雨量值三个主要字段. 以下是核心代码部分: <UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/pr…
原文:ArcGIS API for Silverlight 调用GP服务准备---GP模型建立.发布.测试 第一篇.GP降雨量等值线建模.发布及测试 在水利.气象等行业中,要在WebGIS中实现空间分析功能,如绘制等值线.等高线.等直面.缓冲区等都是经常遇到,经过一段时间的学习和研究,查阅ESRI文档,请教他人,终于可以说是初步实现了等值线功能,这里记录下来详细的操作步骤和图片说明,一方面是对此次努力的总结,另一方面希望也能给后来用到这方面的其他同志们,起个抛砖引玉的作用. 下一篇是关于Silv…
A pair of numbers has a unique LCM but a single number can be the LCM of more than one possiblepairs. For example 12 is the LCM of (1, 12), (2, 12), (3,4) etc. For a given positive integer N, thenumber of different integer pairs with LCM is equal to N…
