EXHIBIT A SCOPE OF SERVICES This scope of services is intended to describe the services and products necessary, but is not intended to be an all inclusive detailed listing of all tasks and actions necessary. GROUND CONTROL The Consultant shall submit a flight and control map prior to any airborne operations. This map shall indicate the proposed control layout, flight lines, altitude assignments and exposure marks. The proposed tile layout and City limit lines shall be plotted on the map. The Consultant shall meet with the City once the map is prepared, to agree on the necessary ground control. The City will place and maintain the necessary field markings within an agreed upon time frame. If the Consultant is unable to perform the aerial photography within the agreed upon time frame, any cost incurred by the City to reestablish and maintain the ground control, shall be reimbursed by the Consultant to the City. The only allowable exception would be delays due to adverse weather conditions. AERIAL PHOTOGRAPHY The Consultant is responsible to ensure that all photography complies with National Map Accuracy Act standards for accuracy and detail. The City requires one set of contact prints and a 24" x 36" photo index sheet for the contact prints. The photos shall be black and white and the negative scale shall be no smaller than 1" = 280'. Aerial photography shall cover the entire City of San Leandro. DIGITAL ORTHOPHOTOGRAPHY Digital orthophotography shall be produced by creating digital elevation models, rasterizing the aerial photoimagery and performing a pixel level rectification of the raster imagery to remove relief displacement at ground level. The digital orthophotographs must meet or exceed National Map Accuracy standards for 1" = 40' scale. Digital orthophotographs shall cover the entire City of San Leandro. Scanning Aerial negatives or film diapositives shall be converted to digital raster images using a precision photogrammetric scanner. All digital image processing shall be performed at high resolution. Resampling of the imagery to quarter foot pixels shall not take place until immediately prior to delivery.
