Install tilecache on IIS

Tilecache is a GIS Component I learned when translating the book GIS for Web Developer. It is located before the GIS server and can cache data of any WMS service, to produce tile-style WebGIS effect. I have been searching for information on tilecache installation and usage for a long time on the Internet, but I have never had any results. Later, I found a piece of "seting up tilecache on IIS" in Google's cache.Article.

 

The cache Effect of tilecache can accelerate the WMS service by 10-times or even higher, but it is an open-source tool developed using Python and Its developer is metacarta labs. We will use tilecache on IIS. (I think IIS is quite useful, compared to Apache)

 

• Download the latest version of Python (2.5.1) [version 2.1 is unavailable ]. I installed ESRI 2.4, so the following versions may be different;
• Run Python installer fow windows and install python in the default directory "C: \ python24"
  
• After installing python, you need to set its environment variables. As shown in:
  
• Add "; C: \ python24 \;" to the variable path.
  
• Download the latest tilecache version 2.0.4 and decompress it to "C: \ Inetpub \ wwwroot \ tilecache:
  
• Open the IIS manager. A shortcut is to enter inetmgr;
• Now we need to enable IIS to parse the Python script. Right-click "default website" and choose "properties", "main directory", and "configuration:
  
• In the displayed ing dialog box, click "add". The following settings are displayed in the dialog box. note two % s:
  
• After the input is complete, the following situations will occur. Now IIS can parse Python:
  
• Right-click the tilecache folder and choose "properties". The dialog box is displayed:
  
• In the dialog box, "directory" and "application"ProgramThe "Application name" of "set" should not exist. Click "new" next to it to see the following situation:
  
• Open the command line window, And in the C: \ Inetpub \ adminscripts directory, type the following two commands in sequence:
  • Adsutil set w3svc/allowpathinfoforscriptmappings true
  • Adsutil set w3svc/1/allowpathinfoforscriptmappings true
• Rename the 'C: \ Inetpub \ wwwroot \ tilecache. cgi 'file to 'C: \ Inetpub \ wwwroot \ tilecache. py'
• Edit the tilecache. py fileCode'#! Delete/usr/bin/ENV Python and change the parameter in service. Load to 'C: \ Inetpub \ wwwroot \ tilecache. cfg '. As shown below:
  
• Create a new cache folder in the tilecache folder to generate the cache directory. We need to give this folder a "writable" permission.
• Edit the tilecache. cfg file in the tilecache folder and modify [cache:
  
  Change
  
• Modify the URL value under [basic]. [basic] is the name of the layer You Want To Cache. This setting must be correct. The following is a layer from metacarta's WMS service named basic
  
• Edit the index.html file in the tilecachefolder and set tilecache. cgi? Changed to tilecache. py?
  
• Now, congratulations, your tilecache installation on IIS has been completed.
  
• Check the cache folder, which has been generated by cache. The basic folder represents the basic layer. You can see many folders:
  
• Now let's generate a cache for the entire map, that is, manually generate the cache. In the command line tool, enter the following command:
  Python "c: \ Inetpub \ wwwroot \ tilecache \ tilecache_seed.py" "http: // localhost/tilecache. py ?" Basic 0 2
• Here, refers to the cache level of the map. You can set it by yourself. If you set it to 0 6, it will generate a map cache of 7 levels, but it takes a lot of time. I did not.
• Modify the content of index.html. Note that titlecache:
  
• Congratulations again, everything is successful.
