MAP+ GRISCHA - The unique geoportal for Graubünden

MAP+ Grischa is the regional extension of MAP+ Suisse, specifically developed for Graubünden. The portal combines cantonal, national and European geodata in a modern, intuitive interface in five languages, including Romansh Grischun!

With over 300 topics across roughly 40 categories at your disposal, everything is clearly structured and easy to browse. Thanks to the «External map services» feature, we also access numerous web services from the canton as well as around 700 federal services.

Powerful measuring and drawing tools, integrated Google Street View, the MAP+ 3D viewer and many other functions make MAP+ Grischa a versatile working tool for administration, business and the public.

Cantonal data - Graubünden and neighboring cantons

MAP+ Grischa brings together all geodata relevant to the population, municipalities and professionals in the canton of Graubünden - directly from official geoservices or quality-checked, prepared and expanded by us.

• Official surveying (updated daily): parcels, planned buildings, owner inquiries, ÖREB cadastre, addresses, place names and more
• Spatial planning: building zones, zoning plans, general design plans (GDP), general development plans (GDP), regional plans
• Environment: federal inventories, natural hazards, water protection, groundwater
• Extended perimeter: official surveying (where available) also for Glarus, St. Gallen, Ticino and Uri - supplemented by all federal data and selected European data

This gives you consistent information across cantonal borders from a single application.
