Understanding Topographic Maps

Overview

Topographic Maps provides an overview of USGS topographic maps including their characteristics, production, and history.

Topographic Map Symbols:

Topographic Map Symbols (paper copies kept in the vertical filing cabinets in the Map and Atlas Collection) lists symbols found on USGS topographic maps. Information about specific survey control points or benchmarks found on each topographic map is maintained in the NGS Data Sheets database maintained by the National Geodetic Survey. Maps for America (US Geological Survey) 1981 (Docs I 19.2:M32/12 1981) includes detailed information on the characteristics, natural features, cultural features, boundaries, names, marginalia, projection, reference systems, and geodetic control found on topographic maps.

Topographic Map Grids:

Four grid systems are shown on most USGS topographic maps:

Latitude/longitude - see Latitude and Longitude for an an introductory description. Geocoder will convert an address or zip code to lat/long coordinates.
Public Land Survey grid - see Township and Range for an introductory description and Principal Meridians and Base Lines for a map of the 34 base meridians in the United States.
In California there are three base meridians--San Bernadino, Mt. Diablo, and Humboldt. The initial point of the Humboldt Meridian was established on the summit of Mt. Pierce on October 6, 1853 by suveyor Colonel Henry Washington.
The Township Geocoder converts Latitude and Longitude (Lat/Long) values into Township, Range and Section values; and Township, Range and Section values can be converted into polygon centroids in Lat/Long format.
Township and Range-Public Land Survey System on Google Earth displays townships, one-mile sections and quarter-sections on Google Earth. You can also enter a township and range and "fly" to the location in Google Earth.
Universal Transverse Mercator (UTM) - see Universal Transverse Mercator (UTM) Grid for additional information.
State Place Coordinate System (SPCS) - see State Plane Coordinate System for additional information. Gridding may be based on the North American Datum of 1927 (NAD27) or the more recent North American Datum of 1983 (NAD83).

Topographic Map Placenames:

Geographic Names Information System (U.S. Geological Survey) Contains information on 2 million physical and cultural geographic features in the United States. The database includes all names appearing on USGS 1:24,000 topographic maps, USFS maps, National Ocean Service nautical charts, National Park Service maps and other sources. Includes over 100,000 historical entries for places that no longer exist. Information provided for each entry includes the name as recognized by the U.S. Board on Geographical Names, type of feature, country, geographic coordinates, and the USGS topographic quadrangle on which the feature is found. Each entry links out to the National Map, Google Maps, TerraFly, TopoZone, TerraServer DRGs, TerraServer DOQs, Tiger Map Service and EPA's Find your Watershed.

United States--Historical
- General Land Office (GLO) Survey Plats and Field Notes (US Bureau of Land Management) Survey plats and field notes are the official documents resulting from the survey of federal public domain lands by the US General Land Office. From an historical perspective survey plats and field notes give a picture of the land during its original settlement and are now used extensively by title companies, surveyors, historians, genealogists, biogeographers and other researchers. Survey plats in many instances are the first maps of an area and show the locations of rivers, early settlements, roads, forts, and trails as well as topographic features.
  
  The original purpose of the survey was to divide the vast public domain into lots that could be sold to raise funds for the federal government and to encourage settlement of the public domain and has its origins in the Land Ordinance of 1785. Land title was transferred from the federal government to individuals through land patents. Survey work was done using the Public Land Survey System (PLSS) which divided the public domain into six-mile square townships and one-mile square sections. The PLSS was utilized in 30 states and resulted in 133,000 survey plats and 2.75 million pages of field notes that date from the 1820s.
  
  Surveyors first created field notes describing in detail each mile of line surveyed; monuments placed; terrain over which they passed; and nature of the soil, vegetation and timber, salt licks, and other items of economic interest. Survey plats are the graphic representation of the information contained in the field notes. They show the PLSS boundaries (e.g. section boundary lines) and some of the physical and cultural features found in the notes.

U.S. Army Map Service Topographic Maps (US Army Map Service) Includes approximately 450 topographic map series produced by the AMS and its successor agencies (Defense Mapping Agency, National Imagery and Mapping Agency, and National Geospatial-Intelligence Agency). These series were distributed to participating map libraries beginning in 1945. These maps are now historical in nature in that they reflect the political and cultural features of the time period in addition to the topography. Scales vary but many are 1:250,000. Some series still offer the most detailed topographic map coverage for the area. The HSU Library became a depository for the Defense Mapping Agency in 1976. Series received include the Joint Operations Graphic, Tactical Pilotage Chart and Operational Navigation Chart listed above.
