Maps included in assignments and reports need to be cited, just as you would cite any other source of information.
The maps you are using may be found in print sources such as atlases, books or periodicals, or in sheet format; or they may be an electronic image you found on the web or one created using GIS software.
The source and format will dictate which elements to use in your citation, these elements include, but are not limited to the map title, author, publisher, place of publication, scale, URL (address of website) and date of publication, retrieval or creation. For the correct method of citing you will need to consult the relevant referencing style guide for your assignment or course.
For example -
Australia. Bureau of Mineral Resources, Geology Geophysics, & Geological Survey of Queensland. (1970). Australia 1: 100 000 geological series: SH. 9146 2007 Mundubbera. Canberra: BMR.
See our Referencing style guides pages for examples of how to cite maps or you can do a web search such as citing maps to find various examples of citing maps in various styles. The style guides created by universities are a good source of information.
It’s important to keep in mind that the key to citing correctly is consistency and always check with your lecturer if you have any questions.
