Inspired by the last "show contour lines on Google Earth" (image 1, Image 2), I wrote a dynamic implementation to show Chinese cities and airports in Google Earth, the following figure shows the effect. You can also open Google Earth and add an address in the temporary directory: http://www.sharesh.cn/chinacity/index.asp? Or download this kml file: http://files.cnblogs.com/Tangf/ChinaCity.zip (if you open it with a
I have finally studied track navigation, but it should be noted that my track navigation is not a general professional concept of navigation, I just figured out my own idea of how to navigate the track to prevent lost in the wild.This problem is not serious, and it seems easy to solve. However, my mobile phone is a smartphone, which is complicated because many navigation software does not support smartphone, the rest do not support trajectory navigation.However, when I went out to climb the moun
Description
This example shows how to return query results as kml. kml is an XML-based format for representing features and attributes. it's commonly used in Google maps and other geographic applications. returning query results in kml preserves the symbology originally set by the map author.
To run this example, pan to an area of the map click execute query. all
Kml-keyhole Markup Language
From https://developers.google.com/kml/documentation/kml_tut? Hl = ZH-CN
Kml is a file format used to display geographical data in the earth browser (such as Google Earth, Google Map, and Google mobile map. Kml uses a tag-based structure containing nested elements and attribute
Kml is short for keyhole Markup Language kml. It is a file based on XML syntax and file format, it is used to describe and save geographical information such as points, lines, images, and broken lines and display them in the Google Earth client. (previous versions of kml can be read by Google Earth and saved as kml 2.0
We know that in googleearth, we can share our own coordinate information, using kml.
What is kml? Kml stands for keyhole markup language. It is a markup language (markup) based on the XML (Extensible Markup Language) syntax standard.Language), using the tag structure, containing nested elements and attributes. I will not talk much about the

First, create a new project and add a timer control and button. When you click the button, the content in dynamic. kml is dynamically updated, so that the coordinates of the point are changed in real time. The Code is as follows:
private double xx=100;private double yy=30;private void timer1_Tick(object sender, EventArgs e){ xx +=0.03; yy +=0.03; FileStream fs = new FileStream("products.kml", FileMode.Creat
1. Can kml be stored locally?
No. It must be placed on the web server of the network.
2. Can kml be used on a map?Yes! But some elements are not available. Please visit: http://code.google.com/intl/zh-CN/apis/kml/documentation/kmlelementsinmaps.html
3. Why do I upload kml! Is it 404 in the browser?Mime needs to be a

The effect of the following code is that kml uses networklink to continuously execute phython code on the server and dynamically change the longitude and latitude coordinates of points.
First, create a new virtual directory under the default website under Internet information service, and then create an application on the "virtual directory" tab under the directory, and then click "Configure ", go to "application configuration", click Add (for example
How to open a DXF file? There are many ways to open a DXF file, because many software can open the DXF file now, but the most common is to open it using CAD. What is the file in the DXF format? AndDownload XP SystemLet's take a look at it together!
What is the DXF format?
Using the OGR library to create data in the DXF format is basically the same as creating data in the SHP format. The code is identical except the registration driver.
Note that the OGR creation of the DXF format requires the head. DXF in the data folder. Therefore, you must first set the directory of gdal_data. Use the following code to set the environment variab

OpenGL is a set of open 3D graphics software interfaces recently released by SGI. It is suitable for a wide range of computer environments. From personal computers to workstations, OpenGL can achieve high-performance 3D graphics. OpenGL not only provides operations and control over simple elements, but also provides many functions for modeling complex objects. However, we usually like to use tools such as AutoCAD, 3DS, and 3dmax to create models, and we already have many such models. How can we
