; Cave: Kingsdale Geodetic GPS Survey ; Surveyors: Kevin Dixon and Meg Stark ; Dates: 30 June 2013, 13 July 2013, 10 August 2013 ; Instruments: Leica Geosystems SR530 GPS, KD SAC Combi Compass+Clino, Disto D2 ; SVX File: Created 19 September 2013 by K.Dixon ; Note that Mohole and Keld Head can be found in 3CGPS.SVX ; Geodetic L1/L2 GPS post-processed using RTKlib open source software with IGS precise ephemerides and OS base station ; data at Giggleswick, Leeds and Richmond. ; ETRS89 co-ordinates determined from double difference integer fixed baselines ; from Giggleswick. Quality checked with baselines computed from Leeds and Richmond. ; ETRS89 co-ordinates converted to OSGB36 and OND using OS online co-ordinate transformer. ; Standard deviations for positions are from RTKlib and do not include any component from the OS transformation. ; OS state that OSTN02 which determines OSGB36 easting and northing is error free ; OS further state that OSGM02 which determines the elevation has a standard error of 0.02m ; OSGB36 co-ordinates are for the OS 100km square SD ; to obtain full length co-ordinates, add 300000 to Easting and 400000 to Northing *begin kdgps *date 2013.07.01 *export vent ;valley entrance centre of drum outer edge, start of Footleg survey *export 3c23 ;Bull Pot stainless steel bolt and washer in bedrock *export tb2 ;presumed to the be the start of the Jingling Pot cave survey *export 3c24 ;Aquamole top centre of square section upright bar in bedrock near entrance *export tr ;Rowten Pot tree root presumed to be start of Rowten Pot cave survey *export 3c21 ;Rowten Pot -3c21 is top centre of hex head bolt in bedrock between P hangers *export 3c22 ;Jingling pot, stainless steel bolt and washer in bedrock *export 3c19 ;Simpsons Pot cow tag drill hole, start of cave survey *export 3c18 ;Turbary Pot stainless steel bolt marker *export 3c17 ;Swinsto stainless steel bolt marker *export 3c25 ;King Pot stainless steel bolt marker at entrance *export 3c26 ;Yordas Pot drill hole marker at entrance ; known magnetic azimuth of 328.0 at Bull Pot Farm ; observed compass bearing of 328.0 ; therefore zero magnetic error ; magnetic north 02 degrees 04 minutes west of grid north as per British Geological Survey online calculator for July 2013 ; therefore zero correction term for survex is +2.067 degrees ;commented out by Simon Cornhill 2019.04.27 as it is superseded by *declination auto in West_Kingsdale_System.svx ;*calibrate compass +2.067 *fix 3c17ae 69387.403 77533.612 380.458 ;sdE 0.0011m, sdN 0.0006m, sdElev 0.017m *fix 3c18ae 69505.327 77501.959 373.918 ;sdE 0.0013m, sdN 0.0009m, sdElev 0.0024m *fix 3c19ae 69619.341 77867.710 372.762 ;sdE 0.0009m, sdN 0.0008m, sdElev 0.0016m *fix 3c20ae 69907.233 77407.244 268.392 ;sdE 0.0007m, sdN 0.0005m, sdElev 0.0013m *fix 3c21ae 69821.522 78000.083 359.751 ;sdE 0.0011m, sdN 0.0009m, sdElev 0.0021m *fix 3c22ae 69894.817 78381.654 371.175 ;sdE 0.0007m, sdN 0.0005m, sdElev 0.0013m *fix 3c23ae 70214.196 78748.504 357.144 ;sdE 0.0011m, sdN 0.0006m, sdElev 0.0020m *fix 3c24ae 69927.791 78338.410 370.621 ;sdE 0.0010m, sdN 0.0007m, sdElev 0.0015m *fix 3c25ae 70788.934 77381.486 372.604 ;sdE 0.0013m, sdN 0.0008m, sdElev 0.0018m *fix 3c26ae 70575.072 79101.851 319.640 ;sdE 0.0153m, sdN 0.0048m, sdElev 0.0162m ; Valley Entrance 30 June 2013 *flags surface 3c20ae 3c20gnd 1.292 - DOWN ;3C20ae is GPS antenna base, 3C20gnd is top of rock outside entrance 3c20ae vent 2.513 302.5 -24.5 ;vent is centre of outer edge of drum 3c20ae 3c20 4.103 302.5 -23.0 ;3c20 is stainless steel bolt and washer on right hand wall inside cave ; Bull Pot 30 June 2013 3c23ae 3c23 1.229 - DOWN ;3c23ae is GPS antenna base, 3c23 is stainless steel bolt and washer in bedrock ; Jingling Pot 30 June 2013 *flags surface 3c22ae 3c22 1.267 - DOWN ;3c22ae is GPS antenna base, 3c22 is stainless steel bolt and washer in bedrock 3c22 jp 7.094 106.0 -2.0 ;jp is P hanger closest to trees on edge jp tb1 2.634 142.0 -1.0 ;tb1 is base of eastern most tree jp tb2 2.279 142.0 -1.0 ;tb2 is base of western most tree ; start of Jingling Pot cave survey is reportedly base of tree for direct hang, presumed to be one of the two trees above ; Aquamole 30 June 2013 3c24ae 3c24 1.132 - DOWN ;3c24ae is GPS antenna base, 3c24 is top centre of square sectioned upright bar in bedrock ; Rowten Pot 13 July 2013 3c21ae 3c21 1.93 - DOWN ;3c21ae is GPS antenna base, 3c21 is top centre of hex head bolt in bedrock between P hangers 3c21ae tr 4.145 274.0 -42.0 ;tr is tree root which is presumed to be start of Rowten Pot cave survey ; Simpsons Pot 13 July 2013 3c19ae 3c19 1.040 - DOWN ;3c19ae is GPS antenna base, 3c19 is drill hole on rock lip above entrance which had cow tag ; Turbary Pot 13 July 2013 3c18ae 3c18 0.847 - DOWN ;3c18ae is GPS antenna base, 3c18 is stainless steel bolt and washer in bedrock wall ; Swinsto Hole 13 July 2013 3c17ae 3c17 1.689 - DOWN ;3c17ae is GPS antenna base, 3c17 is stainless steel bolt and washer is bedrock wall ; note empty drill hole 0.260m vertically above stainless steel bolt ; King Pot 10 August 2013 3c25ae 3c25 7.270 131.0 -35.0 ;3c25ae is GPS antenna base, 3c25 is stainless steel bolt and washer in bedrock at entrance 3c25ae 3c25gnd 1.31 - DOWN ;3c25gnd is fell ground level ;Yordas Pot 10 August 2013 3c26ae yp1 8.572 241.5 -33.0 ;3c26ae is GPS antenna base yp1 yp2 11.662 242.0 -11.0 ;yp1 and yp2 are intermediate points on rocks yp2 3c26 11.340 265.0 -07.5 ;3c26 is 8mm drill hole on right wall at narrowest part of cave entrance 0.16m below roof *end kdgps
