Manifold GIS installation and different aspects of usability
23 November, 2008
As part of the work on community mapping in Hackney Wick, we used the area for a project with the Development Planning Unit MSc students. As part of this work, and since we’re using Manifold GIS in this project, we offered the students the use of Manifold GIS for this exercise.
From an experienced system administrator perspective, installing the package and linking it to the licence server is a very quick and easy task. However, for the students it proved to be a difficult task – especially with Windows Vista where special procedures must be followed to enable the administrator account and install Manifold GIS. The process is rather scary for the average user, and the information architecture and links on the Manifold website are not clear enough to guide a novice, non-technical user through the installation process. As a result, many didn’t manage to make the package work. After a brief explanation and being pointed in the right direction, the installation issue was resolved.
This is a very interesting aspect of usability which, many times, is overlooked. When looking at a GIS or a component of geotechnology, it is worth evaluating its usability for different audiences. With software, I would differentiate between ‘end-user’, ‘programmer’ and ‘system manager’ usability. For each of these archetypes it is possible to evaluate whether the package is easy to use for this role. For example, programmer usability can be evaluated by examining how long it takes for a programmer to learn how to manipulate the system and perform a task with it. The new generation of APIs such as those that are used by OpenStreetMap or Google Maps are very programmer usable – it takes very little time to learn them and achieve something useful with the system.
The installation of Manifold GIS, therefore, scores high on system manager usability, but low on end-user usability – and, importantly, there are far more of the latter than the former. Some small changes to the website with a clear installation guide can improve the situation significantly, but a real change to the installation process that removes the need to switch to the administrator account is the real solution…
