Where do I put the def query such that I'm performing Service Area for only Canadian streets using the HERE NA Streetmap Premium. I tried by putting a def query on Routing_Streets to show COUNTRY = 'Canada' but it still shows service area polys into the USA
I know one of the options is to input a Line barrier like the 49th parallel across or a poly barrier, but it would be simpler to just filter on an attribute already in the HERE dataset
I'm not sure it is possible to restrict the US streets from a service area solve where the locations are in Canada, unless you have a copy of the data that excludes the US.
One possible solution would be to add a polyline restriction barrier along the US/Canada border in your analysis. If the facility locations are all in Canada, then the service area will not be able to traverse into the United States.
