Karnataka Neeravari Nigam Limited Tender

A) Defining Area of Interest (AOI) for drone survey based on reservoir boundary format and finalising it from the concerned official from the said office. B) Identifying suitable locations potential for Ground Control Points (GCPs) and establishing them using Differential GPS. C) Planning flinght mission based on the given requirements and schedule and update the concerned office in terms of total number of flinghts, time required for each flight and survey schedule. D) Planning flinght mission based on the given requirements and schedule and update the concerned office in terms of total number of flights, time required for each flinght and survey schedule. E) Processing of drone data using standard software to generate the following Output. o Orthomosaic 10cm (GSD approximately 5cm)- JPG/TIFF/ECW formats. o Digital Surface Model (DSM) o Digital Terrain Model (DTM) o Contours generated from DSM (shapefiles) o Contours generated from DTM (shapefiles) o Point Cloud. F) Superimposition of revenue map onto drone orthomosaic G) Preparation and submission of final maps (5 hard copy) for FRL and FRL+3 ft in the templates prescribed by the concerned office and submission of all the data in standard GIS format (raster map) H) Transferring boundary points for FRL+3 ft at every 30m interval, from map on to the ground. I) Collection of original RS Maps, combining the same with respect to control points, providing the LAT/LONG fixed points and Demarcation of FRL contour +3 ft on RS Map duly showing chainages at every 30 mtr. J)Establishment of control points with respect to the co-ordinates and levels adopted for the project using high end DGPS and other digital equipments and carry out detailed topographical survey using total station / Drone / Lidar and capturing all the topographical features. Levels shall be taken at 10 m grid centre to centre for the entire project area and also for area 100 m beyond the boundary limit. In addition levels shall also be taken for salient points such as ridges, valley, tracks, nalas so as to depict the true shape of the terrain including any relevant data required in the interest of work as per the instructions of the Engineer in Charge

Demarcation of FRL contour on ground for Chulkinala reservoir by direct contour method using DGPS / Total Station / Auto Level , including ground verification at all locations required to be monumented in terms of both position as well as elevation with respect to MSL. Work also involves providing list of such points in terms of numbers, position (geographical coordinates) and elevation (with respect to MSL). etc. complete as directed by Engineer-in-Charge.

Preparation of topographical survey drawing on various scales such as 1:5000, 1:2500 and 1:1000 scale including contours at 0.5 m interval and Compilation of base map for preparation of capacity tables and assessment of storage capacity as per the standard guidelines of Survey of India etc. complete as directed by Engineer-in-Charge.
