如何安装Himap进行时
|
一.下载HiMap软件开发包v2.1版本: HiMap_sdk_v2_1.
二.安装HiMap运行时，您需要将HiMap.Carto.dll,
HiMap.Driver.dll, HiMap.Geometry.dll,
HiMap.MapControls.dll,HiMap.Style.dll,HiMap.CoordinateSystem, HiMap.Base ,
KMGisLib
dll 拷贝到您的应用程序所在的移动设备的目录中，例如：\ProgramFiles\
DeviceApplication1
"。您可以使用 Microsoft ActiveSync 或 存储卡来拷贝文件。
三.使用VS2005自动部署KMGisLib.dll:
1. 在[解决方案资源管理器]窗口中的[DeviceApplication1]项目上单击鼠标右键，选择[添加]->
[现有项]。
2.找到"himap_v2_for_netcf"解压后的文件目录，在[文件类型]中选择"可执行文件 (*. exe;
*. dll *. ocx)"。
3.选择 "KMGisLib.dll" 文件和"gdalce.dll"，点击[添加]按钮。
4.在[解决方案资源管理器]窗口中选择"KMGisLib.dll"文件和"gdalce.dll", 在[属性]窗口中，设置
文件属性[复制到输出目录：如果较新则复制]和[生成操作：内容]。
5.部署您的程序。
一.
创建项目:MyHimap
1. 请您将himap_v2_for_net_cf.zip文件解压到本地磁盘目录，您将看到以下文件:
HiMap.Base.dll, HiMap.Carto.dll, HiMap.CoordinateSystem.dll, HiMap.Driver.dll,
HiMap.Geometry.dll, HiMap.MapControls.dll, HiMap.Style.dll, KMGisLib.dll.
2. 启动Microsoft Visual Studio 2005 (以下简称为VS2005), 在[文件]菜单中选择[新建]
->[项目]。
3. 在[新建项目]窗口中，选择[Visual C#]->[智能设备]->[Windows Mobile 6 Professional]
->[Device Application], 在[名称]栏中输 入"myHiMap"，->[确定]
二. 为工程添加HImap引用
1. 在[解决方案资源管理器]中，鼠标右键单击[引用]项，选择[添加引用]。在[添加引用]
窗口中，选择[浏览]标签，选择以下7个文件： HiMap.Carto.dll, HiMap.Driver.dll,
HiMap.Geometry.dll, HiMap.MapControls.dll,
HiMap.Style.dll,HiMap.CoordinateSystem
.dll, HiMap.Base.dll，点击[确定]按钮。
三.
将Himap的.NET框架精简版组件添加到工具箱
1. 右键点击[工具]窗口的空白处，在弹出的菜单中选择[选择项]。
2. 在[选择工具箱项]窗口中，选择[.NET Framework 组件]标签，点击[浏览]按钮。
3. 在弹出的[打开]窗口中，找到"HiMap.MapControls.dll"文件，并点击[打开]按钮。
4. 在[选择工具箱项]窗口中，点击[确定]。
5. 添加文件成功后，"MapControl"将出现在[工具箱]中。
四.
将HiMap的MapControl控件添加到窗体并且编写一些基础方法的代码。
1. 在[工具箱]窗口中找到 "MapControl" 控件，将"MapControl"控件拖拽到"Form1.cs
[设计]" 窗口, 设置mapControl1的属性[Dock: Fill]。
2. Form1.cs代码窗体，在"namespace myHiMap"上方添加"using HiMap.Carto;" 和 "
using HiMap.Driver;"代码。
|
using HiMap.Carto;
using HiMap.Driver;
|
3. 向Form1添加"Form1_Load"事件, 并且输入以下代码.
|
//定义地图对象
Map _map;
private void Form1_Load(object sender, EventArgs e)
{
_map = new Map("test");
mapControl1.Map = _map;
//这个xml文件是地图图档文件
mapControl1.Map.FromKmd("\\Storage Card\\nyc.xml");
mapControl1.MapRefresh();
HiMap.MapControls.Tools.ITool pTool = new
HiMap.MapControls.Tools.ToolPan();
pTool.OnCreate(this.mapControl1);
this.mapControl1.CurTool = pTool;
}
|
4. 使用Microsoft ActiveSync(本示例使用的是4.5.0版本)连接工具，将PC连接到Windows Mobile 5.0 for
Pocket PC
或 Windows Mobile 6 Professional的移动设备。
5. 右键点击[解决方案资源管理器]窗口中的工程[myHiMap]，在弹出的菜单中选择[部署]。
6. 在成功部署后，将himap_v2_for_net_cf.zip文件中的KMGisLib.dll文件拷贝到移动设备"\Program
Files\myhimap"
目录中。或者，使用VS2005的部署功能将其自动部署到程序目录中，请参考"如何安装HiMap运行时"来获得这部分
的详细帮助。
五. 将地图文件拷贝到移动设备，并且运行项目
1. 请将文件"nyc.xml, nyc_mainroads.shp, nyc_mainroads.shx,
nyc_mainroads.dbf"拷贝到移动设备目录"\Storage Card"
，可以使用Microsoft ActiveSync同步工具或存储卡来拷贝。
2. 点击VS2005中的[启动调试(F5)]按钮。
3. 恭喜您！您的第一个HiMap工程运行成功。
1. HiMap.Base.dll
2. HiMap.Carto.dll
3.
HiMap.CoordinateSystem.dll
4. HiMap.Driver.dll
5.HiMap.Geometry.dll

1.摘要
这篇文章总结了如何由地图坐标转换到屏幕坐标。
2.预览
由地图坐标得到屏幕坐标.
//设置一个地图坐标点的值
|
double dMapX = 123.4000;
double dMapY = 40.3200;
//将这个地图坐标点转换成屏幕坐标点
System.Drawing.Point screenPoint
= mapControl1.MapToScreen(dMapX, dMapY);
//显示结果
MessageBox.Show("屏幕 x:" +
screenPoint.X.ToString() + "\r\n" + "屏幕 y:" + screenPoint.
Y.ToString());
|
1.摘要
本文主要讲述如何将屏幕坐标转换成地图坐标
2.详情
|
//定义屏幕坐标点
int iScreenX = 100;
int iScreenY = 200;
//从屏幕坐标转换到地图坐标
IPoint mapPoint =
mapControl1.PointToMapPoint(iScreenX, iScreenY);
//显示结果
MessageBox.Show("地图 x:"+
mapPoint.X.ToString() + "\r\n" + "地图 y:" + mapPoint.Y.
ToString());
|
1.示例:
1. 根据经纬度位置绘制.
|
//定义一个Brush对象
Brush brush = new SolidBrush(Color.Yellow);
//定义Pen、color和尺寸
Pen pen = new Pen(Color.Blue, 2);
//绘点
mapControl.DrawPoint(pen, brush, 123.111, 41.111,
2);
|
2. 根据屏幕坐标绘制.
|
//定义一个矩形Rectangle
Rectangle rectangle = new
Rectangle(10, 20, 5, 5);
//绘点
mapControl.DrawPoint(new
Pen(Color.Red), new SolidBrush(Color.Blue), rectangle);
|
2.备注
绘制的前提条件：MapControl控件必须包含图层。
1.示例:
|
//定义Pen
Pen pen = new Pen(Color.Blue, 2);
//定义一些以屏幕坐标为单位的点
Point[] arrPoint = new Point[5];
arrPoint[0].X = 40;
arrPoint[0].Y = 30;
arrPoint[1].X = 100;
arrPoint[1].Y = 30;
arrPoint[2].X = 120;
arrPoint[2].Y = 80;
arrPoint[3].X = 50;
arrPoint[3].Y = 70;
arrPoint[4].X = 40;
arrPoint[4].Y = 90;
//绘制线段
mapControl.DrawLine(pen, arrPoint);
|
有3个函数可以绘制临时线段.
1. 使用屏幕点集合绘制.
|
public void DrawLine(Pen pen, Point[] pts);
|
2. 使用地图点集合绘制.
|
public void DrawLine(Pen pen, IPoint[] pts);
|
3. 使用屏幕坐标的起点、终点绘制.
|
public void DrawLine(Pen pen, Point pt1, Point pt2);
|
1.示例:
|
//定义Pen
Pen pen = new Pen(Color.Blue, 2);
//定义Brush
Brush brush = new SolidBrush(Color.Yellow);
//为多边形定义一些屏幕坐标点
Point[] arrPoint = new Point[4];
arrPoint[0].X = 40;
arrPoint[0].Y = 30;
arrPoint[1].X = 100;
arrPoint[1].Y = 30;
arrPoint[2].X = 120;
arrPoint[2].Y = 80;
arrPoint[3].X = 50;
arrPoint[3].Y = 70;
//绘制多边形
mapControl.DrawPolygon(pen,brush,arrPoint);
|
2.备注:
因为多边形包括多个点，所以必须先创建一个点集合。
1.示例:
|
//定义Pen
Pen pen = new Pen(Color.Blue, 2);
//绘制椭圆
mapControl.DrawEllipse(pen, new Rectangle(30,
40, 120, 125));
|
2.备注:
有两种绘制椭圆的方法.
1. 使用屏幕坐标矩形来绘制.
|
public void DrawEllipse(Pen pen, Rectangle rect);
|
2. 使用屏幕坐标的左x值，上y值，宽度和高度来绘制.
|
public void DrawEllipse(Pen pen, int x, int y, int width, int
height);
|

string strQueryResult = "";
for (int i = 0; i < this._mapControl.Map.LayerCount; i++)

break;
case GeometryType.Point:
strSearchField = "ObjectID";
break;
default:
strSearchField = "ObjectID";
break;
}
//得到一条数据
cls = (HiMap.Carto.IFeatureClass)featureLayer.Class;
//进行模糊查询，查询"HWYNAME"字段[char数据类型] 包含 'PAL%'值的
string strTemp = strSearchField + " like '" + strQueryValue + "%'";
//查询数据
ifc = CSearch.GetFeatureCursor(_mapControl, i, strTemp);
//定位到数据
ift = ifc.Next();
if (ift != null)
{
while (ift != null)
{
strQueryResult +=
ift.GetValue(cls.Fields.FindField(strSearchField)).ToString();
strQueryResult += "\r\n";
ift = ifc.Next();
}
}
}
MessageBox.Show(strQueryResult);

• 查询功能的子函数.
|
/子函数，查询某层的数据指针
//查询某层的数据指针
public static IFeatureCursor GetFeatureCursor(HiMap.MapControls.MapControl
map, int
varIndex, string condition)
{
//获得layer对象
IFeatureLayer lyr = (IFeatureLayer)map.Map.GetLayer(varIndex);
IFeatureClass fcls = (IFeatureClass)lyr.Class;
//创建query filter
IQueryFilter qf = new QueryFilterClass();
//设置查询条件
qf.WhereClause = new StringBuilder(condition);
//查询
IFeatureCursor cur = fcls.Search(qf);
//返回指针
return cur;

摘要:
本文将讲述使用HiMap进行坐标转换的必要步骤。
请将您的地图转换成HiMap自己的格式, 显示速度非常快.
视频下载: [HiMap速度测试 - 加载大数据量矢量地图]
代码下载: [HiMap_gsf_示例代码 vs2005 & vs2008]
本视频显示了HiMap操作大数据量的矢量地图的速度, 我们将shp文件转换成了HiMap自己格式
(.gsf 格式), 然后加载, 速度非常快.
测试地图文件<>的原始大小是: 79.5 MB, 188
MB, 和 1.95 MB, 合计: 270 MB.
经过HiMap转换后, 总的gsf地图文件大小是: 398 MB. (其中test_file.gsf: 204 MB, test_file.kdb:
188 MB, test_file.kpi: 5.37 MB)
未找到平台找到目录下的.csproj文件，将 4118C335-430C-497f-BE48-11C3316B135E
一句
改为 3C41C503-53EF-4c2a-8DD4-A8217CAD115E ，即可运行。
无法找到
PInvoke DLL KMGisLib 请将gdalce.dll和KMGisLib.dll拷贝至移动设备或模拟器的
程序目录中，例如：\Program Files\myHiMap\KMGisLib.dll
1.无法找到地图文件，请检查地图文件的路径。
2.当前视野未被包含在图层设置的缩放比例范围内。
