  5. Corners Working with corner data in the GIS is NOT a survey. Using the corner data is not surveying. Why do we have multiple corners? Presentation JAMES C. KAISERMAN PLS/PE WASATCH COUNTY SURVEYOR

  6. Today's Situation Enter the GIS (Geographic Information System) The requirement of counties to manage vast amounts of data Maps Deeds Parcels Zoning Etc Need for the use of computers and servers to store & deliver this data timely Survey Control or Section Data is the base layer of an accurate GIS system. 6

  7. Re-Locating A Section Corner When searching for a section corner, there are three (3) terms that a surveyor uses to determine the status of the original corner. Found Obliterated Lost 7

  8. Found This is a fairly self explanatory term. When an original section corner is deemed found that means: The original stone or marker was found and deemed to be undisturbed Or enough of the original accessories were found to locate where the monument was placed. This is obviously the best case scenario when searching for a section corner. If a surveyor deems a section corner found, that means there is little or no doubt that you know exactly where the original surveyor placed the monument in question. Wasatch County s Experience - - - The original glo stones are still intact and in place in the out lying areas of the valley, the foothills and less populated areas of the county. Development over the years has destroyed many of the original stone monuments and their accessories however by destroying the monument they have not destroyed the original position of the section corner. 8

  9. Obliterated A corner is obliterated when There are no remaining traces of the monument or its accessories, but whose location has been perpetuated or may be recovered beyond a reasonable doubt, by the acts and testimony of interested land owners, competent surveyors, other qualified local authorities, witnesses, or by some acceptable record evidence . (ACSM definitions of surveying and associated terms p. 65) 9

  10. Obliterated Wasatch County s Experience - - - The vast majority of the destroyed corners in Wasatch County are in this category. The original monument and its accessories have been destroyed but the location of the monument has been perpetuated by collateral evidence (fences, roadways, canals, aerial photos, etc). Unfortunately, to gather enough evidence to re-locate an obliterated corner can be very time consuming and costly. the majority of the time with a dependant re-survey there is not enough money per corner to gather the necessary evidence to accurately retrace the location of an original monument forces the surveyor to prematurely deem the corner lost when in fact it is not. 10

  11. Lost To determine a corner lost , the surveyor must prove that the corner in question cannot be recovered beyond reasonable doubt, either from traces of the original marks or from acceptable evidence or testimony that bears on the original position, and whose location can be restored only by reference to one or more interdependent corners. (ACSM definitions of surveying and associated terms p. 65) Establishing a Lost corner use the method of proportioning to establish the corner in question. A proportioned corner is one who falls on a line drawn, depending on the situation, between two or four found monuments. 11

  12. Lost The Lingering Effects A typical section should have 8 original monuments. Example from Wasatch County- This survey shows all of the corners that have been set in this section. Section now has 18 monuments around the perimeter. A nightmare for surveyors to have to decide which monument your deed and your neighbors deeds are tied to. Bigger problem in trying to create a survey layer for a GIS system the County Recorder has to decide which deed is tied to which corner. Do you show all the corners? Do you tie every deed to the same corner? What if an original corner was found, do you move the deeds to the new corner? - - Multiple corner situations are difficult to say the least. - - 12

  14. Lost The Lingering Effects BLOW UP OF THE SOUTHWEST CORNER OF SECTION 18 Marker 3 was placed in 1976 when the original corner was deemed Lost . Marker 2 was proportioned using stones found over the last 30 years along this rangeline. Marker 1 is the original stone location found in 2000 during the Provo River Restoration. Error from original stone location: Marker 2 - 31 feet Marker 3 - 147 feet from the original stone. 14
