The entire project was flown using a 6 inch lens and the downtown area was flown using a 12 inch lens. Additional control was recovered from an earlier (1993) overflight. Further control was derived from airborne GPS. Photo orientation was determined from a fully analytical aerotriangulation adjustment. All aerial images were scanned at 12.5 microns. All scanned images were orthorectified using the AT data and the digital elevation model. Mosaicking of the images was done using a manual stitch method. Then, this data was resampled from .25 foot per pixel resolution to 1 foot per pixel resolution. The resampling method is currently unknown.<BR /> <I>Source used: </I>C:\DOCUME~1\EUGENE~1\LOCALS~1\Temp\2c\xml15.tmp<BR /> <DIV CLASS="ph1" onmouseover="doHilite()" onmouseout="doHilite()" onclick="hideShowGroup(this)">Who did this process <DIV CLASS="pe2" STYLE="display:none"> HJW GeoSpatial, Oakland CA<BR /><I>physical address:</I><BR /><DIV STYLE="margin-left:0.3in"> <DIV CLASS="lt"> <PRE ID="original">8407 Edgewater Drive</PRE> <SCRIPT>fix(original)</SCRIPT> </DIV> <DIV> Oakland, CA 94621</DIV> <DIV>USA</DIV></DIV> <BR /> 510-638-6122 (voice)<BR /><BR /> </DIV> </DIV> <BR /></DIV> </DIV> <DIV CLASS="ph2" STYLE="margin-left:0.4in" onmouseover="doHilite()" onmouseout="doHilite()" onclick="hideShowGroup(this)">Process step 2 <DIV CLASS="pe2" STYLE="margin-left:0.2in; display:none"> <I>Process description: </I>Metadata imported.<BR /> <I>Source used: </I>G:\ArcIMS\Website\sfshare\catalog\test\ortho_ti_qft_2001.sid.xml<BR /> <BR /></DIV> </DIV> <DIV CLASS="ph2" STYLE="margin-left:0.4in" onmouseover="doHilite()" onmouseout="doHilite()" onclick="hideShowGroup(this)">Process step 3 <DIV CLASS="pe2" STYLE="margin-left:0.2in; display:none"> <I>Process description: </I>Metadata imported.<BR /> <I>Source used: </I>G:\ArcIMS\Website\sfshare\catalog\test\ortho_ti_1ft_2001.sid.xml<BR /> <BR /></DIV> </DIV> <DIV CLASS="ph2" STYLE="margin-left:0.4in" onmouseover="doHilite()" onmouseout="doHilite()" onclick="hideShowGroup(this)">Process step 4 <DIV CLASS="pe2" STYLE="margin-left:0.2in; display:none"> <I>Process description: </I>Metadata imported.<BR /> <I>Source used: </I>G:\ArcIMS\Website\sfshare\catalog\test\ortho_ti_qft_2001.sid.xml<BR /> <BR /></DIV> </DIV> <DIV CLASS="ph2" STYLE="margin-left:0.4in" onmouseover="doHilite()" onmouseout="doHilite()" onclick="hideShowGroup(this)">Process step 5 <DIV CLASS="pe2" STYLE="margin-left:0.2in; display:none"> <I>Process description: </I>Metadata imported.<BR /> <I>Source used: </I>G:\ArcIMS\Website\sfshare\catalog\test\ortho_ti_1ft_2001.sid.xml<BR /> </DIV> </DIV> <DIV CLASS="pn" STYLE="margin-left:0.4in">Sources</DIV> <DIV CLASS="ph2" STYLE="margin-left:0.6in" onmouseover="doHilite()" onmouseout="doHilite()" onclick="hideShowGroup(this)">Source 1<DIV CLASS="pe2" STYLE="margin-left:0.2in; display:none"> <I>Contribution: </I>Source Contribution: Ground Control Beginning date: 23-Jul-01 Ending date: 15-Aug-01 Source Contribution: Aerial photography Beginning date: 14-Aug-01 Ending date: 28-Aug-01 Source Contribution: Digital elevation model Beginning date: 10-Jun-94 Ending date: 17-Aug-01<BR /> <DIV CLASS="ph1" onmouseover="doHilite()" onmouseout="doHilite()" onclick="hideShowGroup(this)">Currentness of this source <DIV CLASS="pe2" STYLE="display:none"> <DIV><I>Beginning date and time: </I> August 14, 2001 </DIV> <DIV><I>Ending date and time: </I> August 28, 2001 </DIV> </DIV> </DIV> </DIV> </DIV> <DIV STYLE="text-align:center; color:#6495ED">_________________</DIV><BR /> <DIV CLASS="pn">Spatial data quality</DIV> <DIV CLASS="ph2" STYLE="margin-left:0.2in" onmouseover="doHilite()" onmouseout="doHilite()" onclick="hideShowGroup(this)">Horizontal positional accuracy <DIV CLASS="pe2" STYLE="margin-left:0.2in; display:none"> <SPAN CLASS="lt"><PRE ID="original">Designed to meet +/- 2.5 feet at CE90 (NMAS for 1"=100' mapping).
