Tungamull electronic distance measurement (EDM) baseline
Contact the Regional Calibration Officer (listed below under 'contacts') as soon as possible if any of the following information is incorrect or to report any problems with the baseline.
This baseline is a pillared base located at Tungamull, along a disused railway line just east of Rockhampton. Station 1 is located on the southern side of the Rockhampton-Emu Park Rd/Costello Rd/Cobb and Co Rd intersection.
Head east from Rockhampton on the Rockhampton-Emu Park Rd for about 20km past the railway crossing on the outskirts of town. The baseline will be on the southern side of the road (right) at a dirt road intersection (Cobb and Co Rd). A dirt track runs adjacent to the baseline and provides vehicular access to each station.
Keys are needed to unlock the pillars and should be obtained from the local Department of Natural Resources, Mines and Energy office in the town centre.
Type: 7 station Schwendener. Stations are concrete pillars.
Datum RL: The datum plane is based on reduced level (RL) 0.0 metres. RLs for the stations are derived from station 0 - permanent survey mark (PSM) 69732.
Alignment: Base alignment is from station 0 to 6. Offsets are negative to the left and positive to the right of the line viewed from station 0.
- Pillar 1 was disturbed in 2009 due to an upgrade on the intersection of Rockhampton-Emu Park Rd and Cobb and Co Rd. Although the pillar may be stable again, take care when observing this station.
- Pillars are not easily visible from the road as they are on the other side of a tree line.
