The basemap tiles were designed for thematic overlays, so tried to keep the color values subtle, however I realized that there is less room for subtly in web maps than there is for print. There was a temptation to crank the color volume/saturation on some of the elements (similar to other basemaps) to create a stronger figure.
For elevation data I used a 10m at smaller scales, then blended in 15ft and 3ft for larger scales. The canopy texture comes from highest-hit LiDAR postings. The building footprints and stream centerlines are derived from LiDAR as well.
There are several aspects of this basemap still needing cartographic development including representation of over/under-passes, building outlines, and finer tuning of labeling rules so stay tuned. I think we'll be baking tiles every quarter - simultaneously with the updates to our Regional Land Information System (RLIS).
