What is a Geographic Information System?

A Geographic Information System (GIS) displays geographically-referenced information in the form of electronic map displays. 

  • Map data appears in the form of various

    data layers

     (e.g. Buildings, Roads, Parcels), many of which can be queried for more detail. 
  • Map

    layouts

     can be modified to suit your needs by panning and zooming to the appropriate extent, and turning layers on and off as you please.
  • You may

    print your own map

     layout from the online map; you may also view and/or print various prepared maps.

Nearmap Aerial Imagery

Concord recently acquired a subscription to Nearmap aerial imagery. This service provides three high-resolution aerial surveys per year, in Spring, Summer and Fall. The subscription includes each prior years’ surveys back to 2014, all of which may be viewed via a Web Map Service incorporated into the map below.

NOTE: As the Nearmap aerial survey process is regionally-based, not every survey date in the map will produce an image for Concord. 

Here are the NON-productive dates for Concord imagery:

  • 2017: 08-26 and 09-13
  • 2018: 04-09, the first 04-24, and the first 07-09
  • 2019: the second and third 04-11; 04-17, 04-29; 07-25 and 07-31; the first 09-28, and 10-16
  • 2020: 03-09, 03-16 and 03-21
