What is topography and its characteristics?
Surveying is the science of determining the dimensions and contour (three-dimensional features) of the earth’s surface by measuring distances, directions, and elevations.
What element contains a topographic map?
A topographic map represents the accidents of physical geography (hydrography, relief), the elements of human geography (roads of presentation, populations), administrative divisions and toponymy (names of places and places).
What is a topographic map examples?
A topographic (also called physical) map is an image, usually of the relief of the earth’s surface, at a defined scale. Unlike topographic plans, topographic maps represent extensive areas of the territory: a provincial region, a zone, a country or the world.
What is a topographic sketch and what characteristics should it have?
The topographic drawing graphically represents the characteristics of a certain size of land, through conventionally contractual signs. It shows us the natural and artificial accidents, heights or measurements, horizontal curves or contour lines.
How is topography divided and what are its parts?
It is being divided into planimetry, which is studying flat surfaces; and altimetry, which studies heights. In both cases it is done through mathematical calculation. It is in charge of graphically signifying the Earth’s surface from large sectorizations.
What are the parts of topography?
Roughly speaking, topography comprises three branches or subdivisions:
- surveying. Considered in many ways an autonomous discipline, it is dedicated to the measurement of distances from the Earth’s surfaces, that is, measurement of areas and definition of legal limits.
- Classic topography.
What are the classes of surveying?
Multiple types of topography are stipulated:
- 1 – Smooth.
- 2 – Wavy.
- 3 – Strongly wavy.
- 4 – Hilled.
- 5 – Strongly undermined.
- 6 – Mountainous.
What elements help the interpretation of the topographic map?
In the topographic maps, the scale, the direction of the geographic and magnetic North, GPS references, symbols, relationship with other plains, the creative organism and the year of its elaboration must be indicated. A plane is the graphical representation of a certain region.
What are the lines on a topographic map called?
All the information about the relief that a topographic map offers lies in the representation system that we call contour lines, for which it is essential to become familiar with this system in order to be able to correctly interpret the different terrain features.
What should a topographic sketch contain?
-The drawing by coordinates. -The drawing of the profiles. -The stockings. The growth of a topographic drawing requires calculations so that the description accurately reflects the measurements and distances projected within the piece of paper.
What is a topographic map and its characteristics?
Its own main characteristics are: It is a scale representation of the territory. It is a delimited representation of a territory, as it contains only the details that are considered relevant or of interest. It is a schematic representation, as it uses usual signs to indicate the information.
What are the characteristics of a technical drawing?
Technical drawing encompasses jobs such as sketches and/or sketches, schematics, diagrams, electrical and electronic plans, representations of all kinds of mechanical elements, architectural plans, urban planning, etc., resolved through the help of geometric concepts, where they are applied. mathematics, geometry
What elements make up a topographic drawing?
The length of each line.
- The direction of the meridian.
- The graphic scale of the map with the note. Corresponding to indicate the scale at which the was drawn. Map.
- A legend or symbol key as long as they are not the. Conventional.
- A correct title.
- In the topographic maps should be placed the. Interval of the level lines.
