Online vector tagging (plotting) Tutorial

1. Import/Export the DXF format of the AutoCAD file

2. Online annotation of vector annotation containing DOT/line surface (kml/kmz/SHP/DWG/DXF)

3. Import and export annotation vectors (supported formats include kml, kmz, SHP, and GPX (GPS coordinates ))

4. Vector tagging is automatically superimposed on satellite images for download (vector raster)

5. Open the labeled vector points, lines, faces, and attributes in AutoCAD.

 

Start the bigemap software and click the edit button in the upper left corner of the software, for example:

650) This. width = 650; "src =" http://www.bigemap.com/Uploads/image/20160929/1475150472127778.jpg "Title =" 1475150472127778.jpg" alt = "a11.jpg"/>

The editable dialog page is displayed, for example:

650) This. width = 650; "src =" http://www.bigemap.com/Uploads/image/20160929/1475150628747763.jpg "Title =" 1475150628747763.jpg" alt = "a12.jpg" width = "768" Height = "481" style = "width: 768px; Height: 481px; "/>

You can selectPoint, line, and surface, And other general tagging tools. The left window is the layer manager. Here we can add layers, delete layers, set layer properties, and add points, lines, and surfaces; delete points, lines, and faces. Right-click the layer manager point, as shown in the following figure:

650) This. width = 650; "src =" http://www.bigemap.com/Uploads/image/20160929/1475151012650210.jpg "Title =" 1475151012316210.jpg" alt = "a13.jpg" width = "773" Height = "598" style = "width: 773px; Height: 598px; "/>

Select New Layer and name my layers, for example:

650) This. width = 650; "src =" http://www.bigemap.com/Uploads/image/20160929/1475151172396451.jpg "Title =" 1475151172108451.jpg" alt = "a15.jpg"/>

Then, select the dot, line, plane, and tool in the toolbar above for plotting, such:

650) This. width = 650; "src =" http://www.bigemap.com/Uploads/image/20160929/1475151322109946.jpg "Title =" 1475151322109946.jpg" alt = "a16.jpg"/>

We can open an existing layer, which can be kml/kmz, SHP, DXF (AutoCAD), GPX (GPS) format, Excel format, CSV format, TXT text format, dat (Southern case) format, and so on. Select File in the upper left corner of the software or right-click the layers on the left and choose import ], for example:

650) This. width = 650; "src =" http://www.bigemap.com/Uploads/image/20160929/1475151796140421.jpg "Title =" 1475151796140421.jpg" alt = "a17.jpg" width = "809" Height = "512" style = "width: 809px; Height: 512px; "/>

Open a DXF (AutoCAD) file and select the coordinate system and projection information of the file. The file is the [Xi'an 80] coordinate system, gaussian projection with a central meridian of 99 degrees (the coordinate system information and projection information here need to be known in advance), after opening, such:

650) This. width = 650; "src =" http://www.bigemap.com/Uploads/image/20160929/1475152157323469.jpg "Title =" 1475152157322.16.jpg" alt = "a18.jpg" width = "809" Height = "453" style = "width: 809px; Height: pixel PX; "/>

Layer positioning:Double-click a layer in layer management, such as my layers, and all elements in my layers are automatically located.

Element locating: Double-click the element object under a layer in the layer management to automatically locate the position of the object to be changed.

 Modify attributes:

Batch modification: click a layer in Layer Management and right-click it. In the displayed dialog box, select layer settings/properties ], select all points, lines, or faces under the layer to be modified, such as 650) This. width = 650; "src =" http://www.bigemap.com/Uploads/image/20160929/1475152676580498.jpg "Title =" 1475152676580498.jpg" alt = "a19.jpg" width = "801" Height = "478" style = "text-align: center; width: 801px; Height: 478px; "/>

You can also modify the information of only one element. In the layer manager, select the image source object to be modified, right click, and select "element settings/properties ].

In the pop-up attribute dialog box, you can modify the following attributes:

1. Modify the color, size, and position of the vertex.

2. Modify the line width, color, and overall position of the dragged line.

3. Modify the fill color of the face, the color of the boundary line of the face, and move the entire face. The perimeter and area of the face are displayed.

4. Display/do not display the annotation names of points, lines, faces, and

5. Right-click the selected vertex, line, surface, and vertex to delete the selected vertex.

6. Right-click the painting point, line, and surface to cancel the previous step.

 

[Save annotation]

After you complete your own annotation, you can save the annotation as a vector format (kml, kmz, SHP, DXF, DWG, etc.) to facilitate opening in other software, such: arcGIS, global Mapper, AutoCAD, etc ...; for example:

All layers or elements can be saved as a whole.

Save all marked as a file: Click Save in the file button in the upper left corner of the software, or point to the top directory in the layer manager and click right-click. In the displayed dialog box, select export]

Save a layer as a file: point to the layer to be saved in the layer manager and click right-click. In the displayed dialog box, select export]

Save an element as a file: point to the element to be saved in the layer manager and click right-click. In the displayed dialog box, select export]

Open vector labeling in AutoCAD]

 For example, the line marked:

650) This. width = 650; "src =" http://www.bigemap.com/Uploads/image/20160930/1475202327844541.jpg "Title =" 1475202327844541.jpg" alt = "a223.jpg"/>

650) This. width = 650; "src =" http://www.bigemap.com/Uploads/image/20160929/1475153425561650.jpg "Title =" 1475153425561650.jpg" alt = "a0000jpg" width = "827" Height = "424" style = "width: 827px; Height: pixel PX; "/>

Export the DXF format directly, for example:

650) This. width = 650; "src =" http://www.bigemap.com/Uploads/image/20160929/1475153793124125.jpg "Title =" 1475151093124125.jpg" alt = "a21.jpg" width = "812" Height = "429" style = "width: 812px; Height: 429px; "/>

Double-click the saved DXF or DWG file and open it in AutoCAD, as shown in:

650) This. width = 650; "width =" 1200 "Height =" 676 "Title =" 1447326967905388.png" alt = "bz17.png" src = "http://www.bigemap.com/Uploads/image/20151112/1447326967905388.png" style = "width: 791px; Height: pixel PX; "/>

[Vector tagging Rasterization-adding and downloading vector tagging and satellite images]

The labeled vector data can be separately saved as described above, and can be uploaded together with satellite images for download.

The labels we want to save are as follows:

650) This. width = 650; "width =" 1200 "Height =" 687 "Title =" 1447327543908099.png" alt = "bz19.png" src = "http://www.bigemap.com/Uploads/image/20151112/1447327543908099.png" style = "width: 801px; Height: pixel PX; "/>

Select the range you want to save. You can select a rectangular box, polygon, import border, standard split, and so on. For example, select a rectangular box to save:

650) This. width = 650; "width =" 1200 "Height =" 720 "Title =" 14473277064820..png" alt = "bz0000png" src = "http://www.bigemap.com/Uploads/image/20151112/1447327706484925.png" style = "width: 791px; Height: 405px; "/>

After selecting the download range, double-click to download (the same as normal download). The pop-up dialog box is as follows:

650) This. width = 650; "Title =" 1447327945285731.png" alt = "bz22.png" src = "http://www.bigemap.com/Uploads/image/20151112/1447327945285731.png"/>

Select the place where the Red Arrow is selected to overlay the annotation layer. Other options are the same as normal downloads. Select stitching, select a level you need, and click OK to start downloading. The following figure shows how to enable the download:

650) This. width = 650; "width =" 1200 "Height =" 696 "Title =" 1447328261874965.png" alt = "bz23.png" src = "http://www.bigemap.com/Uploads/image/20151112/1447328261874965.png" style = "width: 796px; Height: 420px; "/> enlarge an image, for example:

650) This. width = 650; "width =" 1200 "Height =" 701 "Title =" 1447328310420782.png" alt = "bz24.png" src = "http://www.bigemap.com/Uploads/image/20151112/1447328334720782.png" style = "width: 793px; Height: 441px; "/>
