Context and Problem

Context

The project was created in the context of an enterprise GIS initiative, where railway infrastructure data had to be prepared for map visualization, routing, and further analytical use.

Raw graph data and infrastructure objects required manual cleanup and alignment. Without a dedicated tool, this work would have required direct data manipulation, repeated checks, and significant coordination between analysts and developers.

The goal was to create a small practical tool that allowed visual editing and faster preparation of railway graph data.

Problem

The team needed to work with railway track geometry in a more controlled and visual way.

Typical issues included:

• missing or incorrect polyline geometry;
• disconnected graph nodes;
• railway segments requiring manual correction;
• difficulty validating geometry through raw data alone;
• slow preparation of infrastructure objects for further use;
• repeated developer involvement for data fixes that could be handled visually.
