When using ArcGIS, mapping data can be obtained from which sources?

• A. Census
• B. United States Geological Survey
• C. Esri
• D. All of the above

Answer: (D)

Data for maps in ArcGIS comes from multiple trusted sources, and you can integrate them together in one project. The Census Bureau provides demographic boundaries and statistics that are essential for population analyses and mapping by geography. The USGS offers foundational geographic data like elevation models, topography, hydrography, and imagery that underpin many spatial analyses and basemaps. Esri itself supplies its own curated datasets and services, including basemaps and the Living Atlas, a library of ready-to-use layers from Esri and partner organizations. Because ArcGIS can connect to online data services and local files, you can pull in data from all of these sources and combine them to create richer, more informative maps.
