Post Offices, Fresno County, 1870-1890

Summary:

Post office locations in Fresno County, 1870-1890.

Description:

Temporal data was gathered from microfilm records of postmasters and offices in the form of dates for established, discontinued, re-established, and name change events (National Archive, Roll M841, Record of Appointment of Postmasters, 1832 - September 30, 1971). Post offices were then assigned unique geographic locations through a combination of geocoding and manual entry. The geocoding process utilized the Geographic Names Information System database, available from the US Geological Survey. The database contains records for hundreds of thousands of entities across the country, including their coordinate locations.
