Ariel Doumbouya
Ariel Doumbouya is currently the Acting Chief of Cartographic Data Services within the National Geospatial Program (NGP) at the U.S. Geological Survey (USGS). The NGP provides the digital geospatial foundation for the United States, and is responsible for designing, planning, and executing the national topographic mapping program.
As the acting Chief of Cartographic Data Services, Ariel leads the strategy and operations for delivering authoritative geospatial data and services that support The National Map, providing foundational mapping products and geospatial information for the nation. Ariel oversees a multidisciplinary team of cartographers, geographers, and physical scientists, guiding the development and management of digital cartographic resources, spatial data, and innovative mapping solutions.
With deep expertise in geospatial science and program management, Ariel drives initiatives to advance the USGS topographic mapping program, geospatial data standards, practices, and availability. Ariel is committed to fostering collaboration, promoting data accessibility, and supporting the evolving needs of the geospatial community.
Science and Products
US Topo - the Current Generation of USGS Topographic Maps
US Topo maps are modeled on the familiar 7.5-minute, 1:24,000-scale quadrangle maps of the period 1947-1992, but are mass-produced from national GIS databases on a 3-year cycle.The maps are layered PDF documents with geospatial extensions. They are downloadable free of charge through several interfaces.
The National Hydrography Dataset (NHD)
The National Hydrography Dataset (NHD) represents surface waters of the United States including, rivers, streams, lakes, and coastal features. The Watershed Boundary Dataset (WBD) is comprised of hierarchical polygons called hydrologic units that represent surface area over which water drains to a point. Both datasets are updated by stewards and are available by subsets of the United States.
Hydrography Seminar Series - Session 9 (NHDPlus HR)
The USGS Hydrography Seminar Series shares success stories from users, provides information on the National Hydrography Dataset (NHD), Watershed Boundary Dataset (WBD), NHDPlus High Resolution (NHDPlus HR), and other related products, and provides a forum for users to learn more about hydrography-related topics. Seminar 9 is an overview of the NHDPlus HR.
