DTM deliverables shall consist o£ DTM data file in ASCII and coverage format, comprised of masspoints, breaklines, patches and other interim data for the entire project area. • Two foot contour data in ArcGIS 8.2 format as coverages. 9.0 PLANIMETRIC UPDATE HJW is also proposing to determine areas of change and to update the existing planimetry by means of photogrammetric methods. Working closely with the City's staff and by comparing the original photography against the new flight we will determine areas of change. HJW will update all existing planimetric data collected in the original project and deliver in ARC GIS 8.2 format. Planimetric deliverables shall consist o£ • Updated planimetric data in ArcGIS format as coverages. 10.0 DIGITAL ORTHOPHOTOS These orthophotos shall be prepared by scanning the 9" x 9" continuous tone diapositives. The pixel size for the 1"=40' digital orthophotos shall be 0.25'. The digital image shall be orthorectified by correlating the raw pixel images with a digital terrain model of sufficient precision to correct the digital image within accuracy standards of this Scope of Work. Digital ortho data files shall be uncompressed Geo_TIFF files. The 1"=40' scale digital orthophotos shall cover an area equal to 1,500' x 1,000' on the ground that corresponds to the Alameda County Grid System with NAD 83 California State Plane, Zone III (in feet) coordinates. All elevated streets, highways and bridge structures within the City of San Leandro shall be properly rectified to their true position and shall be without any smear or breaklines in the image. The small area vacated by this process maybe filled with a gray shade. Orthophotography deliverables shall consist o£ • Geo_TIFF tiles for the entire project area (1500' X 1000') matching the City's existing grid system and naming convention (conforming to the Alameda County Grid System). MrSID compressed imagery of each the for the entire project area, as well as a mosaic of the entire project area. 11.0 HARD COPY Each 1" = 100' and 1" = 200' base map shall be produced on film written reproducible mylars, at an image quality suitable for blueprint reproduction. These base maps shall be on 24" x 36" .004" mylar sheets with a border and a title block as specified by the City. The neat image area of each Exhibit A Page 5 of 5 03/07/03 Hannon, Jensen, Waller & Associates, ]nc.
