USGS Library
Core Science Systems Mission Area
USGS CSS serves as the primary national civilian mapping agency, including topographic and geologic mapping for Federal and State requirements, national geospatial coordination, satellite operations and remote sensing. Our products and data are necessary to understand, monitor, and detect changes that affect the Nation’s natural and agricultural resources, the economy, public safety, and security.
National Geospatial Program
National Geospatial Program
The National Geospatial Program is the Federal civilian mapping agency and provides the digital geospatial foundation for the Nation. It engages partners and communities of use to collaboratively produce consistent and accurate topographic map data.

GIScience in the era of Artificial Intelligence: A research agenda towards Autonomous GIS GIScience in the era of Artificial Intelligence: A research agenda towards Autonomous GIS
The advent of generative AI exemplified by large language models (LLMs) opens new ways to represent and compute geographic information and transcends the process of geographic knowledge production, driving geographic information systems (GIS) towards autonomous GIS. Leveraging LLMs as the decision core, autonomous GIS can independently generate and execute geoprocessing workflows to...
Grammar to graph—An approach for semantic transformation of annotations to triples Grammar to graph—An approach for semantic transformation of annotations to triples
Data annotation is the process of labeling data to show the outcome that a related data model should predict. In this study, annotation data were transformed into semantic graph triples, mainly for use with the Resource Description Framework (RDF), a type of entity-relationship-attribute data model for graph databases. The transformation of annotation data to semantic graph triples...
Validation of the geometric accuracy of airborne light detection and ranging data for eastern Iowa, 2019 Validation of the geometric accuracy of airborne light detection and ranging data for eastern Iowa, 2019
A geometric accuracy assessment of lidar data collected in eastern Iowa in 2019 as part of the 3D Elevation Program (3DEP) was conducted. The assessment involved evaluating interswath accuracy, same surface precision, point density, absolute accuracy, and consistency with adjacent 3DEP datasets. The results demonstrate that the data meet or exceed the quality level 2 specifications...
