My team is building a web application that will run in the browser and display maps, using either Cesium or Openlayers.
It will display the map, some moving entities in it and will allow the user to draw and measure lines or polygons. All these may have attributes such as name/description etc.
This app will not be connected to the internet, and the maps will be supplied to use by the client (format TBD).
So, I think, we need to set up a local map server which will run in the backgroud to supply the maps, such as ArcgisServer/Geoserver.
We have no prior knowledge with map servers, and we are having a hard time understanding what are the benefits of using the (paid) ArcGIS product over something opensource like GeoServer in our case?
Thank you
