The original data capture of the data in this layer was completed in 2013 using stereo models from the 2009 Virginia State imagery. Subsequent to that an update capture was completed in 2022 using stereo models from the 2017 Virginia State imagery. The most recent planimetric update was completed in 2024 using orthoimagery from the 2023 and 2022 Eagleview Orthophotos. The data in this layer includes decks, patios, pools, and aprons (patios for commercial buildings). </font></p><p style='margin-top:0px; margin-bottom:6px; padding-bottom:1em;'><font size='3'>Contact: Fairfax County Department of <span style='background-color:rgb(255, 255, 255);'> </span>Information Technology GIS Division</font></p><p style='margin-top:0px; margin-bottom:6px; padding-bottom:1em;'><font size='3'>Data Accessibility: Publicly available <span style='background-color:rgb(255, 255, 255);'> </span></font></p><p style='margin-top:0px; margin-bottom:6px; padding-bottom:1em;'><font size='3'>Update frequency: As Needed</font></p><p style='margin-top:0px; margin-bottom:6px; padding-bottom:1em;'><font size='3'>Last Revision Date: 3/1/2024</font></p><p style='margin-top:0px; margin-bottom:6px; padding-bottom:1em;'><font size='3'>Creation date: 1/1/2013</font></p><p style='margin-top:0px; margin-bottom:6px; padding-bottom:1em;'><font size='3'>Layer name: GISMGR.BUILDING_ADDITIONS</font></p></pre></div>
