The software tries to solve some of interoperability problems happened using different softwares in the same SDI
The Shapefile Fixer is a free software that has the aim to clean spatial data from most common geometry errors. The user can decide whether to apply the geometric errors fixing process and / or the coordinates rounding process
The fixing process eliminates geometric errors that may originate from the draw / digitization of data and / or deriver by a data post processing. The most common errors are those relating to duplicate consecutive vertices, self- overlapping lines or polygons with self-intersection / self-tangency.
The process of coordinates rounding aims to eliminate resolution errors, as a matter of fact sometimes happens that in some systems can be detected some micro-overlapping and / or micro-gap not founded in other systems.
