MapChecker checks the status of your Esri based web mapping resources. Run it against a WebMap (ArcGIS Online / Portal for ArcGIS) or Geocortex Essentials Site to quickly see if your map services and layers are accessible and responsive. MapChecker will work against all any anonymously accessible WebMap or Essentials Site. In other words, if your users aren't required to login, MapChecker can check your site. If you'd like to run MapChecker against secured WebMaps or Essentials Sites, an in-app purchase of MapChecker Pro will enable the ability to authenticate against these secured resources. MapChecker Pro also offers additional deep-validation of individual layers. This license is an automatic renewing subscription that will charge the full price of the subscription after the current duration is over.
