篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了嵌入GIS地图服务相关的知识，希望对你有一定的参考价值。
通过开源GMap.NET.Core实现地图服务的应用
1. 引用GMap.NET.Core.dll和GMap.NET.WindowsPresentation.dll（开源的，可以网上下载源代码自己编辑、编译，下载地址：https://files.cnblogs.com/files/Doom555/DLL.zip）
2. 创建GMapProvider
1 GMapProvider m_CurrentProvider; 2 public GMapProvider CurrentProvider 3 { 4 set 5 { 6 if (m_CurrentProvider != value) 7 { 8 m_CurrentProvider = value; 9 m_Gmap.MapProvider = m_CurrentProvider; 10 } 11 } 12 get { return m_CurrentProvider; } 13 }
CurrentProvider = GMapProviders.GoogleChinaHybridMap;
3. 在窗体中添加GMap控件
xmlns:gmap="clr-namespace:GMap.NET.WindowsPresentation;assembly=GMap.NET.WindowsPresentation"
<gmap:GMapControl Grid.Row="1" Name="m_Gmap" Grid.Column="1"></gmap:GMapControl>
4. 在窗体初始化完之后设置GMap的基本参数
1 m_Gmap.MapProvider = CurrentProvider; 2 3 m_Gmap.MinZoom = 1; //最小缩放 4 m_Gmap.MaxZoom = 19; //最大缩放 5 m_Gmap.ShowCenter = false; //不显示中心十字点 6 m_Gmap.MouseWheelZoomType = MouseWheelZoomType.MousePositionWithoutCenter;//缩放模式以鼠标为中心 7 m_Gmap.DragButton = MouseButton.Left; //左键拖拽地图 8 //m_Gmap.MouseLeftButtonUp += M_Gmap_MouseLeftButtonUp; 9 //m_Gmap.MouseLeftButtonDown += M_Gmap_MouseLeftButtonDown; 10 //m_Gmap.MouseMove += M_Gmap_MouseMove; 11 //m_Gmap.MouseRightButtonUp += M_Gmap_MouseRightButtonUp; 12 //m_Gmap.OnMapZoomChanged += M_GmapZoomChanged; 13 m_Gmap.Loaded += M_Gmap_Loaded; 14 //// m_Gmap.MouseWheel += M_Gmap_MouseWheel; 15 //m_Gmap.MouseDoubleClick += M_Gmap_MouseDoubleClick; 16 m_Gmap.IgnoreMarkerOnMouseWheel = true; 17 //m_Gmap.CacheLocation = System.Windows.Forms.Application.StartupPath;//指定地图缓存存放路径 18 19 //initAllUElement();//初始化地图元素 20 21 m_Gmap.Manager.Mode = AccessMode.ServerAndCache;//地图加载模式
5. 实现基本的操作
a. 获取当前窗体的地图边界
RectLatLng selectedArea;
PointLatLng leftTop = new PointLatLng(), rightBottom = new PointLatLng();
1 void M_Gmap_Loaded(object sender, RoutedEventArgs e) 2 { 3 selectedArea = m_Gmap.MapViewBound; 4 { 5 leftTop.Lat = selectedArea.LocationTopLeft.Lat; 6 leftTop.Lng = selectedArea.LocationTopLeft.Lng; 7 8 rightBottom.Lat = selectedArea.LocationRightBottom.Lat; 9 rightBottom.Lng = selectedArea.LocationRightBottom.Lng; 10 } 11 double zoomLevel = m_Gmap.Zoom; 12 double[] LT = WGS2CJ.Gaode_GCJ2WGS(leftTop.Lat, leftTop.Lng); 13 double[] RB = WGS2CJ.Gaode_GCJ2WGS(rightBottom.Lat, rightBottom.Lng); 14 15 //FreshNoFlyZone(LT[0], LT[1], RB[0], RB[1], (byte)zoomLevel); 16 }
b. 地图拖拽
1 void M_Gmap_OnMapDrag() 2 { 3 selectedArea = m_Gmap.MapViewBound; 4 { 5 leftTop.Lat = selectedArea.LocationTopLeft.Lat; 6 leftTop.Lng = selectedArea.LocationTopLeft.Lng; 7 8 rightBottom.Lat = selectedArea.LocationRightBottom.Lat; 9 rightBottom.Lng = selectedArea.LocationRightBottom.Lng; 10 } 11 double zoomLevel = m_Gmap.Zoom; 12 double[] LT = WGS2CJ.Gaode_GCJ2WGS(leftTop.Lat, leftTop.Lng); 13 double[] RB = WGS2CJ.Gaode_GCJ2WGS(rightBottom.Lat, rightBottom.Lng); 14 15 ZoomLevel = (byte)zoomLevel;//用于更新右下角显示 16 17 MapCenterChanged(m_Gmap.Position.Lat, m_Gmap.Position.Lng, 0); 18 19 //if (ZoomLevel >= 13 && m_HeightCheck.IsChecked == true) //还有一个条件 按下了开关 20 //{ 21 // if (thresholdHeight == 0) 22 // { 23 // MessageBox.Show("请输入正确的检测高度!"); 24 // return; 25 // } 26 // ThreadPool.QueueUserWorkItem(SetDemThread); 27 28 //} 29 30 //FreshNoFlyZone(LT[0], LT[1], RB[0], RB[1], ZoomLevel); 31 }
c.创建自己的标记控件
1 <UserControl x:Class="GoogleMap.CustomMarker" 2 xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 3 xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 4 xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 5 xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 6 xmlns:local="clr-namespace:GoogleMap" 7 mc:Ignorable="d" 8 Name="m_CustomMarker" 9 d:DesignHeight="300" d:DesignWidth="300"> 10 <UserControl.Resources> 11 <ResourceDictionary> 12 <local:MarkMarginConverter x:Key="MarkMarginConverter"></local:MarkMarginConverter> 13 </ResourceDictionary> 14 </UserControl.Resources> 15 <Grid > 16 <Image Name="icon" Height="{Binding HW ,ElementName=m_CustomMarker,Mode=OneWay,UpdateSourceTrigger=PropertyChanged}" Width="{Binding HW ,ElementName=m_CustomMarker,Mode=OneWay,UpdateSourceTrigger=PropertyChanged}" Source="{Binding ImgSrc,ElementName=m_CustomMarker,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}" IsHitTestVisible="True" HorizontalAlignment="Left" VerticalAlignment="Top"> 17 <!--<Image.CacheMode> 18 <BitmapCache ></BitmapCache> 19 </Image.CacheMode>--> 20 <Image.RenderTransform> 21 <RotateTransform Angle="{Binding Path=Heading,ElementName=m_CustomMarker,Mode=OneWay,UpdateSourceTrigger=PropertyChanged}"/> 22 </Image.RenderTransform> 23 </Image> 24 <TextBlock Name="lable" Visibility="{Binding Path=bLable,ElementName=m_CustomMarker,Mode=OneWay,UpdateSourceTrigger=PropertyChanged}" Text="{Binding MarkLable,ElementName=m_CustomMarker,Mode=OneWay,UpdateSourceTrigger=PropertyChanged}" Foreground="Red" FontFamily="Arial" Background="WhiteSmoke" Opacity="1" FontSize="15" FontWeight="Bold" Padding="1" Margin="{Binding HW,ElementName=m_CustomMarker,Mode=OneWay,UpdateSourceTrigger=PropertyChanged, Converter={StaticResource MarkMarginConverter}}" HorizontalAlignment="Left" VerticalAlignment="Top"></TextBlock> 25 </Grid> 26 </UserControl>
