Useability and the GeoWeb: Part 1 of ?


Hvorfor er det at man altid tænker den højeste fællesnævner når det kommer til webgis applikationer? Når det drejer sig om webgis er det helt OK at gå efter den laveste fællesnævner ... Når blot der er nok af dem ...

Why is it that we alway choose the highest denominator when it comes to putting af webgis application together? When designing a webgis it is more than OK to target the lowest denominator ... as long as there are many of them ...

But I need a full featured GIS in my browser

Oh no you don’t. We at DTSAgile maintain that there are very few situations that actually call for a web-based GIS. When these web applications are built, they are so complex that only GIS professionals understand how to use them. Perversely, the performance and technical limitations of web development make these applications too limited to be useful for GIS professionals! Give GIS professionals access to professional GIS tools – desktop GIS applications. Citrix or Terminal Services technologies provide an excellent means to do this in a distributed environment. This allows all the GIS applications and data to be co-located in a single data-center, while still having a “desktop” experience at remote locations. Having designed, architected and developed several large implementations, we’ve seen how it can deliver powerful desktop GIS functionality across an enterprise very cost effectively.

If however your goal is to service the public or users in a specific line of business, then you would do well in creating focused applications which help a user solve a specific problem easily – which is exactly what GeoWeb style applications do. The next generation of spatial applications is now arriving on the scene and starting to leverage real GIS analytical capabilities behind the scenes. While the tendency to mimic the indeterminate workflows of desktop GIS packages in a browser has noble goals, implementation, performance, and usability issues usually run rampant and completely swamp any cool-factor. Instead, focus on solving specific business problems by building tools that are tailored to the actual end user. [...]
