Sandra has ongoing points. After we final checked in, we had some issues with geography, and people issues have not been solved.
Now, one fact of geographic factors is that they are bounded. We all know, for instance, that longitudes cowl the vary (-180,180), and latitudes are at all times (-90,90). Even when we alter the coordinate system, it’s going to nonetheless have bounds, because the Earth is a closed form with finite boundaries.
Sandra maintains an utility that lets customers annotate the map with their very own knowledge factors, drawing shapes on the map and recording the coordinates of the form. The code which manages the map layer permits the person to pan across the map, and transparently replace its inner coordinates to stay inside these boundaries. The code which manages the annotation layer, nonetheless, doesn’t. It is going to fortunately allow you to draw a form on New Zealand, and the coordinates could be 177 levels, -183 levels, and even -543 levels. It does not care.
Now, when exporting this knowledge, this seems to not be an issue. Different mapping instruments will obtain a wildly out of bounds coordinate and shift it into the legitimate range- a protected and non-destructive operation.
However when rendering the info, it seems, it is an issue. The annotation layer is not sensible sufficient to try this shifting, so if you happen to scroll across the map a number of instances, and draw a form on New Zealand at, say, -543 levels, the subsequent time you load the info and scroll to New Zealand- your annotations aren’t there. However if you happen to rotate across the Earth a number of instances, like Superman reversing time, the annotations will pop up.
The top result’s a number of very confused customers, and a number of assist tickets that principally quantity to “you rotated the Earth improper, attempt once more”.
The repair can be some comparatively simple arithmetic, however as is continuously with the case with these items, the annotation layer code is a mass of ugly spaghetti and each change is fraught with danger. There are additionally one million different issues on hearth, which implies, “customers get confused however their knowledge nonetheless exists” locations it on absolutely the lowest precedence. So the tickets maintain coming, the customers maintain getting unsatisfactory workarounds, the world retains spinning, and nothing ever adjustments.
