Topographic surveys are something that many people may have heard of, but that they may not necessarily know much about. That being said, topographic surveys are not something everyone will need in their lifetime. Knowing what a topographic survey is and some facts about them can help you determine if you need one or not.
What Is a Topographic Survey?
A topographic survey is a land survey that locates and maps all the surface features that are present in any one area. This means all natural features like hills, valleys, and bodies of water, as well as any manmade features. This is a three-dimensional map that shows all the features of the location.
They will specify things like the feature’s location, the size, the height, changes in elevation, both positive and negative, and more. They are necessary for those that are going to be building or making any changes to a piece of property.
Facts About Topographic Surveying or Land Surveying
There are plenty of things that you can learn from topographic surveys and plenty of things you can learn about them as well.
1. Topographic surveys are three-dimensional – The first thing to note is that all topographic surveys will be three-dimensional. This means that they will be rendered in a three-dimensional printout or in a computer program where they can be shown to the person wanting to do them.
2. They can be used for a ton of different projects – These surveys can be used for new construction, they can be used for utilities, for grading and drainage, and even for remodeling existing structures. The information collected by a topographic survey is essential to a wide range of departments.
3. Topographic surveys are very accurate – These surveys are accurate to the point that they can measure how low a low spot is, the height of a structure, and more. They are accurate to the smallest measure.
4. They can vary in time frame – Not all topographic surveys will take a very long time to complete. Some can be done in as little as a day for small pieces of land, while larger parcels can take weeks. It depends on the size of the plot that is being mapped.
5. They show more than just elevation – These maps show far more than just the elevation of a piece of property. They can show boundary lines, marshes, forests, contours of the land, and more.
