Retirement of Web Map Services

VCGI periodically assesses its suite of Web Map Services to determine if modifications are needed.  We analyze usage statistics to identify "low-use" and "high-use" services, and then target adjustments accordingly.  These adjustments include a range of things such as configuration changes to improve service performance OR adjustments to low-use services to reduce their standing load on the server.  In some cases we may choose to retire services.

So what is changing? Based on our most recent assessment (7/21/2017) VCGI will be making the following changes to our suite of Web Map Services.  The services designated for "retirement" will be supported for the next 90 days (retired on 10/31/2017).  Services designated for "replacement" will also be supported for the next 90 days, but user should begin migrating their applications over to the replacement services as-soon-as-possible.  All services noted in this notice are available via this REST endpoint (http://maps.vcgi.vermont.gov/arcgis/rest/services/EGC_services).
