Introduction to reusable large-granularity GIS component mapviewcontrol

Note: Supermap object encapsulation of this control based on hypermap is only for convenient development. After the source code is compiled, it can be published here.



On the use of components to encapsulate some common functions of GIS components ideas and principles, in the application of Visual Basic event mechanism design reusable large-granularity GIS components (http://www.cnblogs.com/maweifeng/archive/2004/12/21/79977.html) and implements a map browsing control.

In the past few days, I have used some of my own projects and development projects many times.CodeSegment is reconstructed and added to mapviewcontrol. In this way, the functions of this control include:

• Map Browsing
• Zoom in, zoom out, layer...
• Auxiliary controls
• Common functions and processes
• Map management and data source management
• ...
• Spatial Analysis
• Stack, buffer zone
• Spatial Analysis
• Input and Output Excel and access files

All functions can be called with only one sentence of code, so it is very convenient to use these procedures or functions. Due to time and energy problems, no document description is provided. The function can be viewed through the Object Browser. ExampleProgramOnly some functions of the control are included.
