March Updates to the ArcGIS Online Basemaps

March 19, 2015 Paul Heersink

Some updates to the imagery and world topographic basemaps on ArcGIS Online

New contributions to the imagery basemap were published last night on ArcGIS Online, covering 3 communities from across the country. Haldimand County, located in southern Ontario on the shores of Lake Erie, contributed their 2010, 20 cm resolution imagery. Across the country in the interior of British Columbia, the Regional District of Central Okanagan provided their 10 cm imagery from 2014. And further north, on the shores of Great Slave Lake, the City of Yellowknife provided their 10cm imagery from 2012 to help improve the imagery basemap.

As well as the imagery updates, there were a number of updates to the world topographic basemap. All of these updates covered previously published Community Maps participants, mostly in the North West Territories. A list of these updated communities is provided below.

Both the imagery basemap and the topographic basemap are constantly being updated. Another update is expected to occur near the end of March. Check back to this blog for additional updates.
