Why not ask your question on the new OpenStreetMap Community Forum?

how Openstreetmap validate the input that are providing by different users? Is there any tool that will do the validation before uploading the data on server?

See previous questions tagged "quality". E.g. data-verification-process! The answers there answer your question (although not really focussing on the "before" aspect).

There are a fe ways to answer this questions :

  • The editors do a fair bit of validation before upload. JOSM's validator in particular is quite powerfull.
  • The editors also try hard to prevent bad edits in the first place (like iD's polygon tool avoids creating an unclosed building way).
  • The api doesn't do any validation beyond making sure the request is well-formed, and stores the result directly (old versions of the data are kept).
  • There are many Quality Assurance tools to check the data once it is uploaded.
  • Many mappers keep an eye on their favorite areas to fix problems as they occur.
