Answer:
Topographic Survey
This can be defined as a process that involves gathering data about the elevation of points on a piece of land and represent them as a outlines or contour lines on a plan.The reason for carrying out topographic survey is to collect survey data about the natural and the man-made features of the land,as well as its elevations.
The uses for topographic survey
Topographic surveys are used to map and identify the terrain of a land area.They efficiently account for any exiting objects on or near the surface, such as streets,buildings ,manholes,walkways,retaining walls,utility poles ,and trees, topographic also takes into account differences in elevation, which are marked on the survey by contour lines.
Topographic survey helps to assess a land for a new construction or the addition of new development.it is invaluable for showing what the the land looks like and how it would impact or affect construction, and this assessment is relevant for all kind of projects such as road improvements,new housing ,complex construction, major highway construction ,grading ,bridge erection,septic system installation,and drainage projects,e.t.c.
Topographic survey is also very important in for identifying areas that construction may not be feasible or where grading will be required in order to make it feasible. This survey provides architects and builders with required information so as to determine how the land will have be shaped and molded to provide a suitable base for the planned construction.
On completion of an initial project topographic survey can be used as basis for a other subsequent plans and designs.Topographic survey can be used for environmental reclamation projects. This survey and the information they provide on elevation and terrain features can help in the accurate and successful reconstruction of a given landscape.
Considering the question that requires filling the blank space
We see that Geological has to do with beneath the land hence its not suitable
Hence
The first blank should be filled with TOPOGRAPHIC
The second blank should be CONSTRUCTION
The third blank should be filled with SURVEY
Note: A construction survey is one that gives the location and sites for construction activities,
The Fourth blank should be DELINEATION
Delineation can be defined as the act of drawing sketching or tracing an outline.
