Kommunekart Proff is a free, professional mapping application developed by NORKART AS for municipal customers. It is an advanced version of "Kommunekart" that requires a login. This app is designed to provide accurate and up-to-date geographic information to municipal customers for better decision-making.

With Kommunekart Proff, users can access a wide range of maps that provide detailed information about land use, zoning, property boundaries, public transport, and more. The app also allows users to create custom maps and add their own data layers for a more personalized experience.

It is important to note that if you are not a municipal customer, you cannot access this app. However, "Kommunekart" is a similar app for the general public and can be downloaded from Google Play. Please be aware that using GPS in the background can shorten the battery life of your device, but this feature can be disabled in the app's settings.
