NAIP Orthophotography of Indiana, (2018):

Shows the IndianaMap cached REST Service (MapServer) of the 2018 National Agriculture Imagery Program (NAIP) orthophotography for Indiana collected during the 2018 growing season. It was produced using the original GeoTIFF DOQQs of natural-color (4-band) orthophotography, with an established standard resolution of at least 60-centimeters. The imagery was provided to the IndianaMap by personnel of the United States Department of Agriculture (USDA), Natural Resource Conservation Service (NRCS).

Project Background:

The National Agriculture Imagery Program (NAIP) acquires aerial imagery during the agricultural growing season ("leaf-on") in the continental U.S. A primary goal of the NAIP program is to make digital ortho photography available to governmental agencies and the public within a year of acquisition. The purpose of the program is to provide current information regarding agricultural conditions in support of the United States Department of Agriculture's (USDA) farm programs. In addition, NAIP imagery frequently supports disaster response.

NAIP is administered by the USDA's Farm Service Agency (FSA) through the Aerial Photography Field Office in Salt Lake City. This "leaf-on" imagery is used as a base layer for GIS programs in FSA's County Service Centers, and is used to maintain the Common Land Unit (CLU) boundaries.

NAIP imagery products are available either as digital ortho quarter quad tiles (DOQQs) or as compressed county mosaics (CCM). Each individual image tile within the mosaic covers a 3.75 x 3.75 minute quarter quadrangle plus a 300 meter buffer on all four sides. The DOQQs are geoTIFFs, and the area corresponds to the USGS topographic quadrangles.

ArcGIS REST Service Resources:


Download imagery from the USDA Geospatial Data Gateway or the Indiana Spatial Data Portal (ISDP):

NOTE: The ISDP does not currently contain downloadable GeoTIFFs and CCMs for 2018 NAIP imagery, as of February 24, 2020. However, the links to the ISDP "Single File Downloads" and the "Multi-File Download Tool" are provided below so that users can access downloads for other orthophotography from a wide variety of vintages and sources.


Spatial Reference:

The GeoTIFF imagery tiles used for this REST service use the UTM Zone 16, NAD 1983 spatial reference as appropriately expressed in meters.
