Working with Streamlines
I'm modeling winds over terrain in Patagonia, and I need to do maps with windstreams. I can export the streamlines from CFD Software (ANSYS), and I can import them into ArcGIS.
¿How I can represent in ArcGIS a line with a color that is dependent of the variable along it? (Windspeed for example).
Mapping Center Answer:
The answer to this question depends on whether you want to symbolize the line to show a quantitative or a qualitative variable. If you want to show a qualitative variable (one that relates to type or kind, not a numerical value), then you can use the Categories – Unique Values renderer:
I used this approach in the example below showing warm and cold ocean currents:
If you want to show a quantitative variable (one that relays a magnitude message), then you can use the Quantities – Graduated Symbol renderer:
I used this approach in the example below showing the length of ocean currents:
Alternatively, you could use the Quantities – Graduated Color renderer:
But you can see that it will be harder for your map readers to distinguish these categories than if you used size to show the variation in magnitudes.
