研究发现，在Web映射项目中，软件开发者最倾向于使用开源软件，主要动机包括自由安装在不限数量的计算机上、免费许可证费用以及灵活修改源代码。尽管面临使用性挑战，但多数开源软件仍能满足项目需求。MapServer作为开源软件竞争者之一，与商业对手几乎等效，并且与行业保持密切联系，遵循众多开放标准。然而，其在Windows上的安装过程相较于商业产品仍具挑战性。
Summary of findings Investigation 1:
- Software developers were found to be the most aware and most likely to use open source software in their projects.
- “freedom to install the software on an unlimited number of computers” is considered the number 1 potential motive for using OS software followed by“free license charge” and “flexibility to modify the source code”
- A few participants of the user category mentioned challenges they faced with OS software with regards to usability.
Summary of finding for Investigation 2:
- Users usually have very high expectations regarding the spatial analysis they want to see.
- Even in projects that undergo a needs analysis phase, the functional requirements tend to change or “mature” as the project progresses.
- Most of the software used in web mapping projects proves to provide sufficient features for the project needs.
Summary of findings for Investigation 3:
- MapServer is a very competitive software and almost equivalent to its proprietary rivals.
- MapServer is in close contact with the industry and is compliant with numerous open standards.
- Installation of MapServer on Windows remains a challenge as compared to the proprietary products.
