GIS data sources

Public data

In the realm of Geographic Information Systems (GIS), data is sourced from three main categories. First, public datasets, typically curated and generated by government agencies, research institutions, and international organizations, offer valuable insights into various aspects of geography, including demographics, land use, transportation, and environmental factors. These datasets serve as foundational resources for a wide range of applications, from urban planning to environmental conservation.

Private data

Private datasets, on the other hand, encompass proprietary information held by businesses and organizations. This includes customer demographics, sales data, and market insights crucial for strategic planning and decision-making. Such datasets are often generated through sophisticated methods like aerial surveys, sensor networks, and proprietary data collection techniques, providing businesses with valuable intelligence for competitive advantage.
