"""Module for basemaps.
Each basemap is defined as an item in the `basemaps` dictionary.
For example, to access Google basemaps, use the following:
* `basemaps['ROADMAP']`
* `basemaps['SATELLITE']`
* `basemaps['HYBRID']`
More WMS basemaps can be found at the following websites:
1. USGS National Map: https://viewer.nationalmap.gov/services/
2. MRLC NLCD Land Cover data: https://viewer.nationalmap.gov/services/
