Maptables are increasingly used to support collaborative spatial planning processes. Despite the proven benefits and claimed potential of using a maptable in such processes, software applications specifically designed for this device are still scarce. Moreover, often-used applications do not fully exploit the touch functionality of a maptable, or have low usability. To address this gap, we developed and evaluated the Open Geospatial Interactive TOol (OGITO), an open-source software application designed to support collaborative spatial planning processes with a maptable. To develop such tool, we combined human-centred design and Agile software development principles in a co-design effort with intended users and stakeholders. Through iterative development cycles and feedback from users, OGITO was evolved until it satisfied user expectations. In a case study on community mapping in Sumatra, Indonesia, a sample of users evaluated OGITO's usability. Case study participants reported high satisfaction with this tool for the tasks and context given. Our research shows the added value of iterative development and user feedback for improving and further development of the tool's usability and functionality.

映射表越来越多地用于支持协作空间规划过程。尽管已经证明了在这种过程中使用映射表的好处和所声称的潜力，但仍很少为该设备专门设计软件应用程序。而且，经常使用的应用程序不能完全利用maptable的触摸功能，或者可用性很低。为了解决这一差距，我们开发并评估了开放地理空间互动工具（OGITO），这是一种开放源代码软件应用程序，旨在通过地图表支持协作空间规划过程。为了开发这种工具，我们与目标用户和利益相关者共同设计，将以人为本的设计和敏捷软件开发原则结合在一起。通过反复的开发周期和用户的反馈，OGITO不断发展直至满足用户的期望。在印度尼西亚苏门答腊的社区地图案例研究中，一个用户样本评估了OGITO的可用性。案例研究参与者报告说，他们对该工具的任务和背景非常满意。我们的研究表明，迭代开发和用户反馈对于改进和进一步开发工具的可用性和功能具有附加价值。
