  Esri Canada publishes several maps showing the status of data updates for their Community Maps Program. One of the maps shows all of the areas where ‎the imagery has been updated. All of the maps are available here - Esri Canada Community Maps Status - http://maps.esri.ca/updates/tracking/‎ Check the map to see if the Esri World Imagery basemap has Community Maps imagery in your neighborhood. Bernie.Sent from my BlackBerry 10 smartphone on the Bell network.From: JamesSent: Friday, September 15, 2017 12:12 PMTo: bernie.conn...@unb.caCc: talk-ca@openstreetmap.orgSubject: Re: [Talk-ca] High resolution Air photos for New BrunswickSweet!

Sweet! I've been looking at a few places as well and it's very good with
minimal real world shift!
Very nice imagery in remote areas too!

Re: [Talk-ca] High resolution Air photos for New Brunswick

[Bernie Connors]

James,

  I have not undertaken an overall assessment of the Esri World Imagery
basemap.  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.

  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.

How well is the ESRI Imagery aligned with the real world (in General)?

[Talk-ca] High resolution Air photos for New Brunswick

[Bernie Connors]

Hello all,



My apologies if this has already been mentioned on this
list.  The Esri World Imagery basemap is now available as a background
image for OpenStreetMap editors.  In New Brunswick the provincial
government has contributed hundreds of square kilometres of high
resolution, urban air photos to the Esri World Imagery basemap.  There are
thousands of buildings and other features that require editing so they
match the newer, hi-resolution imagery in the Esri World Imagery basemap.
This area in Fredericton is a good example [1] (start an edit session and
choose the Esri World Imagery background).  I posted to my blog with a few
more details [2]
