All; I have a network, Canada National Road Network it is a free download, that I am trying to use for PEI and the City of Charlottetown to find out what area is within X time of various points of interest. I used Here for QGIS to get the initial result but QGIS has a tool built in Network Analyst that has Service Area from Network and from Point, also and QNEAT that has 6 isochrone tools for doing exactly what I am trying to do. For some reason though the results don't seem to match the network. I would expect the from the point of origin the shortest times to be along the lines and radiate out. What tools are you guys using to do this kind of work? Do my values for forward backward both direction need to be numeric? Any tutorials on using these tools? Thanks; Tyler
