This TIGER Data layer was created from the Topologically Integrated Geographic Encoding and Referencing (TIGER) database of the U.S. Census Bureau. TIGER products provide vital information about: Line Features (roads, railroads, hydrography, transportation and utility lines) and Boundary Features (Census Tracts, Blocks, Counties, Places, Tribal Lands, political districts and etc.) More information can be found at TIGER Products.
This layer displays public school catchment boundaries (attendance zones) for select states and school districts across the United States. Data is from September 2013 and was acquired from the National Center for Educational Statistics (NCES).
The Soil Boundaries have been updated to the October 2019 NRCS SSURGO data release.
911 Public Safety Answering Point (PSAP) service area boundaries in the United States According to the National Emergency Number Association (NENA), a Public Safety Answering Point (PSAP) is a facility equipped and staffed to receive 9-1-1 calls. The service area is the geographic area within which a 911 call placed using a landline is answered at the associated PSAP. This dataset only includes primary PSAPs. Secondary PSAPs, backup PSAPs, and wireless PSAPs have been excluded from this dataset. Primary PSAPs receive calls directly, whereas secondary PSAPs receive calls that have been transferred by a primary PSAP. Backup PSAPs provide service in cases where another PSAP is inoperable. Most military bases have their own emergency telephone systems. For more information visit the Homeland Infrastructure Foundation Level Data (HIFLD) website
