This form is for and ALTA and TOPO Survey. ALTA surveys must comply with standards set by the American Land Title Association (ALTA) and the National Society of Professional Surveyors (NSPS). As such, they need to be done as precisely and thoroughly as possible. Topography Surveys are fairly straightforward in principle. With this type of survey, the surveyor draws a map of the land with contour lines to mark different elevations, thereby marking out valleys, hills, drainage, and so forth. Additional land features, such as buildings and other improvements, may also be mapped.
