Line Layers

For line layers in Analyst, if there is no relevant type field, use No column (single symbol).

If there is a relevant type field, set it as the default column. To vary different type fields, assign different stroke colors for each class.

If there are line layers that “go together” with a POI layer, such as Transit Lines and Transit Stops, use the same primary column and color ramp for both. For example, the Mode column is used for both Transit Lines and Transit Stops in Analyst, so the colors match by default.

Using dark basemaps

For certain line layers, using a dark basemap may be appropriate to increase contrast — this is a particularly effective technique when ramp colors indicate some level of "flow". Relevant datasets may include those relating to vehicle traffic or energy load, as shown below:

Traffic Volume – Primary Roads

Stroke:

80 – 7,000	7K - 10K	10K - 13K	13K - 16K	16K+
4A4234	7F6630	C29E4A	DEBA51	F5D55C

Opacity: 80%

Traffic Volume – Primary Roads

Energy Infrastructure – Primary Underground Conductors

Stroke:

0-4 kV	4-7 kV	7+ kV
