f i <br />orthophotography will be created by draping the unrectified raster images over their <br />corresponding digital terrain models. All relief displacement will be removed from <br />the raw image files at ground level on a pixel-by-pixel basis, yielding a set of <br />orthorectified digital photo images. <br />Mosaicking will be performed to ensure a perfect edge match between all orthophoto <br />sheet tiles. Creation of seam lines is performed interactively to ensure that no image <br />flaws result from seam lines passing through tall structures. <br />Radiometric adjustment will be performed to balance and match color tones, <br />brightness and contrast of the imagery over the whole project. Histograms will be <br />applied on a project basis and not just to adjacent tiles, ensuring uniformity of tone <br />over the entire image database. Image editing software will be used to repair any <br />minor flaws on the imagery. <br />The imagery will be tiled into sheets as desired by the City. The digital orthophoto <br />software will be instructed to output a COT file for each orthophoto tile. The <br />completed image data set will be written to CD-ROM disks for delivery to the City. <br />Images will be delivered in the format selected by the City, including ecw files if <br />requested. <br />Ground / Field Topographic Suweys <br />This task involves the survey and data collection of any features to be picked up by crews in <br />the field. <br />• Prior to submitting a cost estimate, we always thoroughly review the survey request <br />as well as the site at hand, both from on-site visits as well as through aerial and satellite <br />imagery readily available through Google Earth. <br />• Our project manager will attend pre-project meetings with the City's staff or other <br />City consultants as may be needed. <br />• We will adhere to the City control system, if any, and provide control deliverables in <br />digital format. <br />• We will adhere to the City's line and symbology requirements as they may pertain to <br />CAD files. This is an issue with which we are very familiar. Working with local <br />municipalities, Counties, and US Governmental agencies, we are familiar with <br />translating into anyone's CAD standards seamlessly. <br />• All of our topographic work products are produced, and will be delivered in <br />Microstation (or AutoCAD if requested). In addition, we will submit ASCII <br />coordinate files along with said DGN/DWG file. <br />• Again, we understand that public relations can sometimes be everything, and we will <br />maintain good public relations throughout the project. <br />• We will perform any additional surveying requested by the City, including the <br />preparation and filing of Corner Records and/or Record of Surveys as required by <br />law. <br />14
