GIS Metadata

Metadata is information about data. Similar to a library catalog record, metadata  documents the who, what, when, where, how, and why of a data resource. Geospatial metadata describes maps, Geographic Information Systems (GIS) files, imagery, and other location-based data resources.

Tippecanoe County GIS aerial photography is 3-inch pixel resolution color and is updated almost every year. Recent Aerial Image available on County GIS page was taken in October 2020 by Eagleview in Bellevue, Washington

Dimensions


Aerial orthophotography, transportation features, contours, spot elevations, and hydrology features are horizontally accurate within +/-2.5 feet of their actual location 90% of the time according to National Map Accuracy Standards for 1"=100' scale mapping. Soils data is accurate within +/-40 feet of their actual locations 90% of the time according to National Map Accuracy Standards for 1"=2,000' scale mapping (please see USDA disclaimers for soil mapping) https://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/survey/?cid=nrcs143_013692 . PLSS section corner locations were surveyed using various methods and have been converted from the records of the County Surveyor and sealed by an Indiana licensed professional surveyor.

Property Lines


Property lines are based on the property maps found in the County Auditor's office and are not accurate representations of actual property line locations since these maps were developed in the 1930s as thematic ownership maps. While you may find that some lines are accurate, others may be off by 10s of feet. The county is currently working on a project to improve the property mapping, however the project may take several years to complete.

All of county mapping data is projected in Indiana State Plane Coordinate System West Zone, reference datum is North American Datum 1983 (NAD83) and North American Vertical Datum 1988 (NAVD 88) and the units are in U.S. Survey Feet.
