In land surveying the exact position and shape of objects on the surface of the earth is mapped. Included in the position is the height of an object. Techniques used are for example the total station, level instrument and GNSS. There is a direct relation between modern Remote Sensing techniques and land surveying and topography and often they are used side by side with land survey techniques providing highly accurate coordinates and remote sensing providing a broader overview. In traditional land surveying and topography objects are located in x,y and z with the addition of an object type. However, nowadays more and more attribute information is collected as well allowing detailed databases and products to be developed in cartography.

An important application for land surveying and topography is in construction and engineering but also in for example land and water management. Where land surveying and topography is about the visible objects on the earth surface, marine surveying and bathymetry is concerned with the objects under the water surface.
