I asked this question because I am a student of marketing.

You start by studying what that is. If you are a student in marketing its going to be in your textbook. This is your homework question. Site rules require you give us your answer. We will not do your assignment for you.

Do you mean Topographic Survey?
Maybe you can find something useful on the website of Thakur International about Topographic Surveys and more.

Hope I helped you!

The tropo prefix means to lean towards, such as a plant leaning towards the sun is an example of tropism.
The topo prefix is more various, but I assume that you know what it means in marketing.
