However, I was responsible for the QC of the most recent, high resolution, urban aerial photography that was collected in 2015 and 2016 in several dozen NB communities. This photography was collected by Pictometry for the provincial government and its primary use is for property assessment. I have reviewed the reports for the ground control, aerial triangulation and orthorectification. The province opted to purchase the AccuPLUS orthophoto product from Pictometry which has a higher level of human intervention in the selection of the images that are used to prepare the orthophotos. This results in orthophotos with a minimum of "building lean". When compared to the provincial GIS datasets available from GeoNB [1] the alignment was very good. Additionally I have heard from several municipal GIS managers and they are also very impressed with the horizontal accuracy of the Pictometry AccuPLUS orthophotos. If I had to put a number to the horizontal accuracy of the Pictometry orthophotos in NB I would say it is better than 15 cm. </div><div><br></div><div> The province of New Brunswick participates in Esri Canada's Community Maps Program. Through this program we contribute GIS data (orthophotos and vectors) that are used to update the Esri World Imagery basemap and the Esri World Topographic basemap. Many other communities across Canada also participate in the program [2]. If these communities are contributing their municipal orthophotos to the program it is safe to say that the Esri World Imagery basemap is very accurate within these communities.</div><div><br></div><div>[1] - GeoNB Data Catalogue - <a href="http://www.snb.ca/geonb1/e/DC/catalogue-E.asp" target="_blank">http://www.snb.ca/geonb1/e/<wbr>DC/catalogue-E.asp</a></div><div>[2] - Esri Canada Community Maps participants - <a href="http://maps.esri.ca/updates/tracking/" target="_blank">http://maps.esri.ca/updates/<wbr>tracking/</a></div><span class="HOEnZb"><font color="#888888"><div><br></div><div>Bernie.</div></font></span></div><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Sep 15, 2017 at 10:35 AM, James <span dir="ltr"><<a href="mailto:james2432@gmail.com" target="_blank">james2432@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">How well is the ESRI Imagery aligned with the real world (in General)?<br></div><div class="gmail_extra"><br><div class="gmail_quote"><div><div class="m_8865522430447310136h5">On Fri, Sep 15, 2017 at 9:32 AM, Bernie Connors <span dir="ltr"><<a href="mailto:bernie.connors@unb.ca" target="_blank">bernie.connors@unb.ca</a>></span> wrote:<br></div></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div class="m_8865522430447310136h5"><div dir="ltr"><p class="MsoNormal" style="font-size:12.8px"><a name="m_8865522430447310136_m_-5039045973991600163_m_6266613818957074713_m_-7692088877833260202_OLE_LINK1">Hello all,</a><u></u><u></u></p><p class="MsoNormal" style="font-size:12.8px"><u></u> <u></u></p><p class="MsoNormal" style="font-size:12.8px"> My apologies if this has already been mentioned on this list.
