Include a reference list somewhere on your physical map to credit the sources you use.
Chicago Manual of Style -- Formatting reference list entries for different formats: Purdue OWL guidance
Create an in-text citation that refers to a complete citation in an alphabetized reference list at the end of the work. APA uses author/date (Jones, 2009) citations. For more examples and variations see the general citation guides.
If the map does not have an author or corporate author, bring the title to the first position in the reference list citation and use key words from the title in the in-text citation.
If the map has not been given a formal title, create your own logical title and place it in [brackets] to indicate such.
Indicate that the cited item is a map, aerial photograph, etc. with the appropriate format placed after the title. Example: [map]
Document the scale if known; if unavailable use the phrase "scale not given."
