• Just to create the 2D maps, that we so conveniently use, we need a topographic map. Any location on a 2D map has to be adjusted to the 'z' value at the place. The most common source for this 'z' value is a topographical map.
• Topographical maps are consulted and integrated into the deisgn and planning for pretty much any infrastructure project. So the railways, highways, gas lines, water pipes, pipelines anything is impossible without accurate topo maps.
• In telecom, view-shed analyses are performed with the use of topographical maps to determine the suitable locations to place cell-phone towers to provide maximum coverage.
• In the case of military, the same view-shed analysis is used to determine strategic locations to construct watch towers and in the placement of units. Because without a knowledge of topography (and of course, curvature of earth) our armies stationed in high hilly terrains will not be able to protect themselves from being visible to the hostile armies.
• While constructing dams, topography plays an important role in deciding the dam location, the dam catchment as well as the submerge areas.
• When I was in high school, one of my first projects using topomaps was to determine landslide susceptible areas in a hilly town. I used topography along with the duration of rain, soil type and location of roads to determine areas prone to landslide.
• Topographic maps can also be used to perform flood analyses, since natural water flow follows the terrain’s gradient.
• Topographical maps plays a crucial role in soil-conservation and a lot other nature-conservation planning.
• During any natural hazard or man-made crisis, emergency planners rely on topographical maps to determine the safest location to relocate affected people.
• I have even used topographical maps to determine the annual roof-top solar potential for the buildings in a city.

Answer:

Just to create the 2D maps, that we so conveniently use, we need a topographic map. Any location on a 2D map has to be adjusted to the 'z' value at the place. The most common source for this 'z' value is a topographical map.

Topographical maps are consulted and integrated into the deisgn and planning for pretty much any infrastructure project. So the railways, highways, gas lines, water pipes, pipelines anything is impossible without accurate topo maps.

In telecom, view-shed analyses are performed with the use of topographical maps to determine the suitable locations to place cell-phone towers to provide maximum coverage.

In the case of military, the same view-shed analysis is used to determine strategic locations to construct watch towers and in the placement of units. Because without a knowledge of topography (and of course, curvature of earth) our armies stationed in high hilly terrains will not be able to protect themselves from being visible to the hostile armies.

While constructing dams, topography plays an important role in deciding the dam location, the dam catchment as well as the submerge areas.

When I was in high school, one of my first projects using topomaps was to determine landslide susceptible areas in a hilly town. I used topography along with the duration of rain, soil type and location of roads to determine areas prone to landslide.

Topographic maps can also be used to perform flood analyses, since natural water flow follows the terrain’s gradient.

Topographical maps plays a crucial role in soil-conservation and a lot other nature-conservation planning.

During any natural hazard or man-made crisis, emergency planners rely on topographical maps to determine the safest location to relocate affected people.

I have even used topographical maps to determine the annual roof-top solar potential for the buildings in a city.
