topic Network Analyst Providing Wrong Distances in ArcGIS Network Analyst Questions https://community.esri.com/t5/arcgis-network-analyst-questions/network-analyst-providing-wrong-distances/m-p/190600#M1958 <HTML><HEAD></HEAD><BODY><SPAN>Hello all, </SPAN><BR /><BR /><SPAN>I am fairly new to GIS, and have been using the Network Analyst to route from one city to another. The routing part is going fine, but when ArcMap gives me the driving distance, it is way off. For example, I routed from one city to another and got a driving distance of &lt;0.1 mile. When I used the measure tool to measure the distance between the two cities in a straight line, I get 286 miles. The data is all using WGS 1984 coordinate system if that is of any use. Any help? Thanks.</SPAN></BODY></HTML> Thu, 19 Jun 2014 15:08:57 GMT ElijahMeyer 2014-06-19T15:08:57Z Network Analyst Providing Wrong Distances https://community.esri.com/t5/arcgis-network-analyst-questions/network-analyst-providing-wrong-distances/m-p/190600#M1958 <HTML><HEAD></HEAD><BODY><SPAN>Hello all, </SPAN><BR /><BR /><SPAN>I am fairly new to GIS, and have been using the Network Analyst to route from one city to another.
