Looks like you got all the right answers.

A cartographer or mapmaker. He (she) usually bases the maps on the work of a topographer. 1) "Cartography' or mapmaking (in Greek chartis = map and graphein = write) is the study and practice of making representations of the Earth on a flat surface. Cartography combines science, aesthetics, and technical ability to create a balanced and readable representation that is capable of communicating information effectively and quickly." Source and further information: http://en.wikipedia.org/wiki/Mapmaking 2) "The term topography originated in ancient Greece and continued in ancient Rome, as the detailed description of a place. The word comes from the Greek words τÏŒπος (topos, place) and γραφία (graphia, writing).[4] In classical literature this refers to writing about a place or places, what is now largely called 'local history'. In Britain and in Europe in general, the word topography is still sometimes used in its original sense." "The objective of topography is to determine the position of any feature or more generally any point in terms of both a horizontal Coordinate system such as latitude and longitude, and altitude. Identifying (naming) features and recognizing typical landform patterns are also part of the field. A topographic study may be made for a variety of reasons: military planning and geological exploration have been primary motivators to start survey programs, but detailed information about terrain and surface features is essential for the planning and construction of any major civil engineering, public works, or reclamation projects."
