RFP for ANAND & other Seven DISTRICTS Resurvey project
iii. Accuracy levels required: same as their respective control point
The description of the location of the control point along with a sketch shall be submitted to
SC&DLR.
Note: In case any village tri-junction has not been marked and monumented by any of the
primary or secondary control points or even if it is tertiary control points, then they should be
explicitly monumented as per the parameters mentioned for secondary control points.
(1) The coordinate lists and descriptions of the locations shall be submitted to
SC&DLR .The locations and ID s of all the control points should be
maintained in GIS Form.
(2) The coordinate list should be supplied both for geodetic system (lat/long)
and Projected system-Universal Traverse Mercator , i.e the UTM projection
of the respective area
(3) In case a village tri-junctions has not marked and monumented by primary,
secondary, or tertiary control points, the same should be monumented as per
the parameters.
General Requirements
1. Village boundaries are to be marked.
2. The(X, Y, Z) coordinates for the control points should be given in spherical coordinates
as well as in Cartesian coordinates separately.
3. The (X, Y) coordinates should be in WGS 84.and Z in MSL( Mean Sea Level)
4. The agency should specify the conditions and specification of the instruments/system
used to acquire the required accuracy.
5. Some base lines for calibration with monumentation should be formed at selected
locations for maintenance.
6. A sketch for each category of control points shall be submitted showing the location of
control points along with description for easy identification.
7. A district map showing all the Primary, secondary and tertiary control points with
coordinates shall be submitted to the SC&DLR.
