Using Park Tiles
All of the “layers” that make up Park Tiles are available as individual tilesets on our MapBox hosting account. As each layer was cached individually, we recommend that you follow this hierarchy (bottom to top) when using the tilesets in your map:
- PT Shaded Relief – Shaded Relief
- PT Urban Areas – Urban area polygons
- PT River Lines – Small scale rivers
- PT Admin Lines – Country and State boundary lines
- PT Park Poly – National Park unit polygons
- PT Mask – Polygon feature class that slightly masks non-US countries
- PT Hydro Features – Large scale hydrography
- PT Admin Labels – Labels for Countries and US States
- PT Roads – Roads
- PT Road Shields – Road Shields
- PT Park Points – National Park unit points
- PT Hydro Labels – Hydrography labels
- PT City Labels – City labels
- PT Park Labels – National Park unit labels
All of the Park Tiles tilesets have a prefix of “PT”.
The position of your overlay(s) in the above hierarchy depends on the type of feature (point, line, or polygon).
Point data can either be placed on top of all features or, if the points are obstructing the view of city or park labels, underneath the labels:
- To place points on top of all features, append the layer to the bottom of the hierarchy
- To place points underneath city and park labels, insert the layer in between PT Hydro Labels and PT City Labels
- To place points underneath city, park, and hydro labels, place the point layer in between PT Hydro Labels and PT Park Points
Guidelines for placing line layers is similar to point layers. If placed on top of all services that make up Park Tiles, labels will inevitably be covered up.
- To place lines on top of all features, append the layer to the bottom of the hierarchy
- To place lines underneath city and park labels, insert the layer in between PT Hydro Labels and PT City Labels
- To place lines underneath city, park, and hydro labels, place the point layer in between PT Hydro Labels and PT Park Points
For most polygonal data, it is best to have the reference information on top. To do this, insert any polygon layers between PT Shaded Relief and PT Urban Areas.
Note: If the fill of the Park polygons is obstructing the view of your polygons, replace the PT Park Poly layer with PT Park Poly No Fill.
