Definition: NMS1 stands for "New Map Submission". It's a feature that allows users to submit new maps or changes they've made to existing ones, often during construction projects. This process helps improve transparency and accuracy in the map data. The exact definition varies by organization, but generally it refers to the ability of the map creation system to manage new submissions more efficiently. In a practical sense, NMS1 ensures that all changes are recorded correctly and can be easily accessed by any team or individual.
