Finding reliable free GIS data is one of the biggest challenges faced by GIS professionals, students, researchers, engineers, environmental consultants, and planners. While governments and organisations around the world publish thousands of valuable geospatial datasets, discovering them can be surprisingly time-consuming. Many datasets are hidden behind different government portals, research websites, or sector-specific platforms, requiring users to search multiple sources before finding the data they need.
Whether you're building a web map, conducting environmental assessments, analysing infrastructure, planning renewable energy projects, or studying urban development, having access to high-quality spatial data is essential. The challenge isn't that the data doesn't exist, it's knowing where to find it.
This is where GeoAtlas changes the way people discover GIS data.
GeoAtlas is a global GIS data explorer designed to help users quickly find trusted public geospatial datasets by countryand industry sector. Instead of searching dozens of websites individually, users can browse curated collections of authoritative datasets from government agencies, research institutions, environmental organisations, and public bodies—all organised into logical categories that reflect real-world GIS workflows.
Whether you're a beginner learning GIS or an experienced professional working on complex projects, GeoAtlas saves time by bringing together some of the world's most valuable public GIS resources in one place.
Why Finding Free GIS Data Is So Difficult
Open data initiatives have transformed the geospatial industry over the last decade. Organisations now publish an incredible range of spatial datasets covering everything from population statistics and environmental monitoring to transportation networks, marine conservation, renewable energy, public health, and land ownership.
The problem is that these datasets are scattered across hundreds of independent websites.
A typical GIS project might require downloading data from the Office for National Statistics, Ordnance Survey, DEFRA, Natural England, UKCEH, the British Geological Survey, CEFAS, National Highways, and several local authorities. Each website has a different interface, different licensing information, and different download methods.
Searching for reliable GIS data often takes longer than analysing the data itself.
GeoAtlas solves this problem by acting as a single discovery platform where users can explore trusted public GIS datasets organised by sector and country, making it much easier to identify the right source for every project.
Urban Planning & Smart Cities
Cities are constantly evolving, and GIS plays a critical role in supporting sustainable urban development. Urban planners, architects, transport engineers, local authorities, and developers all rely on spatial data to understand how communities grow and interact with their surroundings.
GeoAtlas provides access to trusted datasets from organisations including:
