GIS实验报告课件

1、实验报告GIS应用软件开发专业：测绘工程班级：10级测绘三班姓名：学号：指导教师：胡一亚撰写时间：2021年5月20日星期一目录一、程序运行演示2二、问题及解决方案6三、源程序代码7四、心得体会14程序运行演示1.新建工程文件,并实现file中的根本功能,显示地图根本要素.如图1图12.在工具栏加载按钮,按钮功能是对当前视图缩小3倍；在工具栏加载工具,工具功能在地图上标注当前日期.如图2图2按钮实现缩小3倍功能操作,如图3图33.点击地图节点,弹出如图4,图5菜单并实现菜单中的内容:AddData.,所有图所不可见图54 .点击图层节点,弹出如图6菜单并需要实现菜单中的内容I-打"图

2、导一性表I去除当前图提SetMaximumScaleSetMinimumScaleLayerSelectable唱放子.三字交宴E重用c图65 .点击LegendClass,弹出符号选择对话框,该对话框供用户按需要选择符号并进行更改.如图7图76 .翻开图层属性表,用户选择某条记录,可弹出如图8,9所示的右键菜单,并实现右键菜单中的内容吧土地使用属性表FIDShapeAHEAPERIMETERcsriGtomtry.,35886.02737.53341esriGeofn9try.«2460644663.8805.esriGeometry,.4670,33351989623esriGc

4、4图8图9问题及解决方案问题1.VS2021与2021之间要进行格式转换,根据所导向的步骤进行,否那么程序将无法正常运行,出现错误问题2.构建好根本框架后,地图文档中要素显示出现问题.此问题要添加licence控件,否那么无法显示地图要素.问题3.使用Toolbar和Toc功能时无法进行操作此问题应在属性设置时建立关联功能.问题4.程序Program文件中要添加相应功能键语句,否那么将无法实现功能.问题5.引用接口,方法,例如ADF,要添加相应的引用,否那么程序出现错误.问题6.在实现两个自定义按钮与工具时,遇到的问题：先直接引用现有项未实现,发现缺少一些东西,后自己直接创立的Basetool

5、和Basecomman嵬；在代码中报错,重新生成解决方案后顺利解决这个问题.问题7.在实现地图和图层节点的右键功能时,遇到琐碎的问题,在这个过程中直接引用老师所给的几个类,但是报错,是由于命名空间未做修改；缺少引用,需要根据错误提示添加相应的引用三、源程序代码usingSystem;usingSystem.Collections.Generic;usingSystem.ComponentModel;usingSystem.Data;usingSystem.Drawing;usingSystem.Linq;usingSystem.Text;usingSystem.Windows.Forms;us
