Deliverable: 1. Raw images (jpg format) (2cm GSD) 2. File scaled and geopositioned orthophoto tiles in jpg & sid compressed format of 2cm resolution and resampled at 5cm GSD. 3. Final scaled and geopositioned ortho tiles in jpg and Sid compressed format of 2cm resolution and resampled at 5cm GSD.4. Final scaled and geopositioned orthomosaic in JPG & Sid format for each 5km. 5. Map file compatible to CAD/GIS in SHP format duly linked with attributes of assets. 6. Quality control report for positional accuracy assessment coordinates to be picked for atleast 5 well defined assets in 1km lengthb from google and same to be measured on the orthophoto coordinates comparsion. The difference between these values should be greater than equal to 3m. 7. The centre line, piers, railway land boundary are to be shown on google earth. (alignment file in dwg format and coordinates will be provided by Railways. Note: 1. This item is complimentary item to LiDAR survey for generation of ortho photos. 2. This item includes prepration of orthophotos for yards also falling in the corridor of 100m. Seperate payment will be made for bigger yards vide relevant item of the BOQ for generation of orthophotos over and above this item.3. The details are to be collected for a corridor of 100m on the finalized alignment. i.e. 50m on either side.Stage Payment: 1. On completion of drone flying and submission of data in the relevant format - 20%. 2. On submission and approval of orthophotos and other deliverables - 60%. 3. On submission of DPR to Railway board and approval by zonal Railways - 20%."
