Public Land Survey Issues
• Original monuments were oftenwood posts, mounds, charcoal, stones, etc.
• More often than not, these corners were not very well perpetuated over time.
Section Corners
Out of the +/-100,000 original corners in Indiana, how many are existent (i.e. properly perpetuated and referenced)?
15-20%?How many of those have state plane coordinates associated with their locations?
30% (5% of the total)?
Survey Control
There is NO inherent relationship between the land fabric and “GPS.”
Survey-grade accuracies cannot be achieved with the typical Wal-Mart purchased GPS. (Survey-grade accuracies require >$20,000 investment in equipment)
Section Corners
Average cost to perpetuate a lost or obliterated corner in Indiana:
$1000-2000 per corner
What impact does this lack of documented
corners have?
• Uncertain reference monuments
• Conflicting reference monuments
• Indeterminate reference monuments
= Higher Cost Surveys that take more time
“Sufficiency”
A legal description is considered sufficient if a competent surveyor can locate it on the ground.
Why might a description be insufficient?
Problems with Record Documents
• Descriptions that do not close• Ambiguous or missing words• Multiple possible interpretations• Plats and deeds with errors• Descriptions that follow ill-defined or
undefined rights of way• Deed gaps and overlaps with
adjoiners
Examples
• Description miscloses by over 900 feet
• “…Beginning at a stone near the corner of Kent’s barn (now gone)…”
• Bounds descriptions that call for each other
• “thence in the shape of a half-moon…”

• “thence in the shape of a half-moon…”
• “…Also, being described by survey, as follows:…”
• An easement, 10 feet in width, adjoining and lying west of the right of way line…”
