Usable local application; some mapping checks remain.
A written land boundary is a route. Calls have to connect, turns have to make sense, and the resulting shape has to be understandable. TaddMap brings that description into a drawing with numerical checks, so inconsistencies can become visible.
The first interface got the emphasis wrong. It was driven by a list of features, and I rejected it as confusing and unintuitive. It could present information without making the problem easier to understand. That is an expensive kind of almost-working software: the capabilities are there, but the person still has to do too much reconstruction.
The correction was to put the drawing at the center. I wanted to follow the boundary and relate the numbers to the shape, rather than work out which panel mattered next. Adding another control would have made the original mistake larger.
That experience sharpened the way I judge the land tools. A calculation can be useful and the application can still fail its user. I look for whether the interface helps someone notice a questionable turn, understand where a result came from, and identify what needs another look.
TaddMap is a local checking aid, with mapping checks still to finish. It supports investigation of a supplied description; professional survey conclusions remain with the responsible professionals. The project is separate from the Countrytyme website. Its strongest lesson so far is about product judgment: a feature list cannot tell you whether a person can see the problem.
