  1. Describe in a sentence or two your overall operational experience related to WMS. (e.g., scientific visualization; geospatial visualization, etc). What kinds of WMS servers and/or clients do you have experience with? (e.g., commercial products, open source, or independent implementations, please provide as much detail as possible).
    • I use WMS as a tool to offer and share the geospatial data on Web. And the WMS servers are MapServer, open source software of University of Minnesota.
  2. What types of applications do you use WMS servers/clients for? Are they suitable for your applications? (e.g., Do they work well with the data types and data manipulations in your application?)
    • It seem that the data type must be strictly accorded with they supports, and it’s not easy to share the data lack of some geoinformation like project string.
  3. Why do you choose to use WMS over other protocols for your applications?
    • As you know, many GIS companies support the WMS, and we can accomplish my task easily with the WMS offered by MapServer.
  4. Are the WMS systems easy to use? (e.g., Is it hard to learn how to use WMS systems?)
    • I think it’s not difficult to use but it not easy to implement the system in the beginning.
  5. Does the performance of the WMS systems you have experienced meet your requirements? (e.g., Does it take a long time to access/view data in WMS systems?)
    • Sustainable, I think.
  6. What operational challenges do the WMS systems present? (e.g., Does it require advanced processing power, large amounts of memory, complex configuration, etc.? Are the systems easy to deploy and maintain?)
    • It needs complex configuration, and it’s not easy to deploy, I think.
  7. How well do the WMS systems scale to large numbers of simultaneous users, or to large datasets?
    • It’s will get slow when those occurs.
  8. Can you provide information on user statistics of your WMS systems? How have the user statistics changed over time?
    • Our system is just a test platform, and the user amount is small.
