### What does this data set describe?

*Title:* Stratification of Indiana 2004
  *Abstract:*
  The United States Department of Agriculture (USDA), National
Agricultural Statistics Service (NASS) area sampling frame is a
delineation of all parcels of land for the purpose of later sampling
the
parcels. The area frame is constructed by visually interpreting
satellite
imagery to divide a state into homogenous land use areas (strata) based
on percent cultivated. The strata are typically defined as low, medium
or
high percent cultivated, non-agricultural land, urban use, agri-urban,
or
water. The boundaries of the strata usually follow identifiable
features
such as roads, railroads and waterways. The strata boundaries do not
coincide with any political boundaries, with the exception of state
boundaries.

2. **How were the data generated, processed, and
modified?**
    
    Date: 2004 (process 1 of 1)
      The area sampling frame for Indiana was constructed for use
in 1989 and
was based on USGS 1:100,000 scale topographic maps, 1:250,000
scale digital Landsat imagery, and 1:100,000 suremaps. The
boundaries were modified in 2004 to conform to USGS 1:100,000 scale
topographic digital raster graphics and digital line graph files.
Individual county files were merged into single state file. The
coordinates for the strata polygons are unprojected to geographic
latitude and longitude (decimal degrees). The spatial data
file format is Environmental Systems Research Institute's ArcView
shapefile format. The shapefile was checked and edited for
topology in 2004. Gaps and overlaps were corrected within and
ESRI personal geodatabase.

### How reliable are the data; what problems remain
in the data set?

1. **How well have the observations been
checked?**
2. **How accurate are the geographic locations?**
    The sources used for digitizing strata boundaries are 1:100,000
scale
Digital Raster Graphics
3. **How accurate are the heights or depths?**
4. **Where are the gaps in the data? What is
missing?**
    There are no known gaps or missing data. This data set includes
the area in
square miles and number of acres for each strata. Boundaries may not be
coincident with strata boundaries of adjacent states.
5. **How consistent are the relationships among
the observations, including topology?**
    Checks for topological consistency were performed on this data
set.
