topic Updating symbology based on information received from external source in Data Management Questions https://community.esri.com/t5/data-management-questions/updating-symbology-based-on-information-received/m-p/78513#M4559 <HTML><HEAD></HEAD><BODY><SPAN>Is it possible to create a layer so as information that is retreived from an external file would change the symbology to reflect the criteria? For example, I have a point base on gps coordinates and while the point is at its location for a time period is is one color, and then when a time period has elapsed, then it would change to another color.&nbsp; I am thinking along the lines of a true/false enabled symbology. Another example would be when looking at the map, I receive an order for a particular area, I see a service truck has been in the area.&nbsp; When the information for the truck is read from the table, if it has been within a determined amount of time (30 min for ex.), the truck symbol would be green, but if it has been over that amount of time, it would change to red.</SPAN><BR /><SPAN>Has anyone attempted something like this and if possible please offer any direction as to help with this research (extensions, forums, websites, etc.). TIA for your assistance.</SPAN></BODY></HTML> Wed, 30 Mar 2011 20:08:32 GMT MichaelDennard 2011-03-30T20:08:32Z Updating symbology based on information received from external source https://community.esri.com/t5/data-management-questions/updating-symbology-based-on-information-received/m-p/78513#M4559 <HTML><HEAD></HEAD><BODY><SPAN>Is it possible to create a layer so as information that is retreived from an external file would change the symbology to reflect the criteria?
