Specialized tools ",:ithill ArcVicw are created
using A venue scripts and can be used to pcrfoml
the fUllctions that arc particular to the needs of
the South Platte. Most of these tools arc
available in the Functions pull-down mCllu and
thcre is on-line and hard-copy documentation
available for instructions on using the tools.

The Compare Common Themcs function
computes the distance betwccn wells (or any
point themc) \I...ith common ID numbers. Ccntml.
GASP. ami Lower Soulh Platte wells located by
GPS can be compared with the locations of the
\\lclls in the swte wcll database using this
common identification number.

Comparisons like these arc used to priontize
which wells should be targeted for review of
their assigned SDF values. The location ofwclls
is imponant fOf assigning an accumtc SDF value
and determining problems in the well databases
from different data sources. Once a wcll has
been identified. the location can be determined
accurately using a GPS unit (Figure 5).

Tools havc also been developed to detcnnine
UTM locations given township, range. ~ection.
and fOOling call locations.

1.3.2 PrintitH! Pre-defined l.avollts

The advisol)' committec wanted a way 10 print
pre-defined layouts or locations selected from
the interface. This includes printing vic"..'s of
background images and othcr land features for
interviews with farmcrs 10 more accurah:ly
locate wells and determine crop types. Tools
were dcveloped to print a series of pre.selected
areas located using the public land survey
~ystem coordinates. Once a more accurate
description for a well has been established with a
famler. the location call be obtained u~ing a GPS
unit (Figure 5). This location can then be used to
dClennine a more accurate SDF value.
