Matthew T. Whitehead (comp.) 2002 vector digital data Columbus, Ohio U.S. Geological Survey http://water.usgs.gov/lookup/getspatial?raintin This is a Triangulated Irregular Network (TIN) of mean annual precipitation for the period 1931-80 for Ohio. This coverage is intended as a data layer representing the spatial distribution of mean annual precipitation in Ohio for the years 1931-80. Information contained in this coverage has been used to obtain values of mean annual precipitation at basin centroid locations (by means of the ARC "tinspot" command) for use in regression models described in: Koltun, G.F., and Whitehead, M.T., 2002, Techniques for Estimating Selected Streamflow Characteristics of Rural, Unregulated Streams in Ohio: U.S. Geological Survey Water-Resources Investigations Report 02-4068 Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in ArcInfo format, this metadata file may include some ArcInfo-specific terminology. A 1:1,100,000 scale (approximate) paper isoline map of mean annual precipitation from Harstine (1991) was digitized as arcs directly into an Albers equal-area projection. The arc coverage was projected to the State Plane Coordinate system, zone 5001, and then coverted to a TIN by means of the "arctin" command. 1931 1980 Dates indicated in source material publication Complete None Planned -84.90978381 -80.48512905 41.97796612 38.42526043 None mean annual precipitation inlandWaters None Ohio none These data are intended for use with regression models given in Koltun and Whitehead (2002).
