A hydrographic survey is just as important as the topographical survey of your land. When you are doing a survey of coastal land or waterways where you may build, you must know what the land looks like when the water is washed away. The surveyor that you hire can create a lovely map for you to use for your building, and you must ensure that you have invested time in learning about these maps, using the maps, and learning about your land.
How Is A Hydrographic Survey Done?
The Hydrographic Survey Company will come to your property to have a look at the waterways where your inspection and survey must be done. You will be given an estimate for the job, and you will learn of any concerns the team has when they are doing the survey. The survey team will let you know when they can begin the work, and they will explain how long it takes to complete the survey.
Once the geophysical survey company get started on the survey, they will use boats and land-based equipment to create a full profile of the land that sits under the water. This profile will include all the topography of the land so that you can see where and how to build in the future. You need to know this information if you plan to ever build there, and you also need to adjust your building plan based on what you see.
How Are The Maps Created?
The geophysical Surveying Company will create a paper map and a digital map that shows the basic topography of the area. These maps are the standard style that you would have seen for many decades before digital technology was introduced. Also, a 3D map will be created that can be used by anyone on the survey team to show a specific view of the topography. You are even given colour codes to denote height and depth. These maps can be used to explain how you may begin to build.
Why Are The Maps Necessary?
You cannot build if you do not have a proper map made for the area, and you cannot submit any of your plans to a zoning board if you do not have a map. Plus, you may need to create a presentation that will use these maps. When you have a 3D map that shows exactly what your land looks like, that makes it much easier for your company to convince the public or an investor that your construction plan will work.
Refreshing Your Maps
You may need to have your maps or surveys refreshed because currents and erosion could change the way that the topography looks. If you are concerned about the structural integrity of your building, dock, or pier, you can have a look at how the earth has changed. You can plan to shore up the buildings that you have, and you can use those maps if you need to resubmit plans to get a new permit.
In Conclusion
You must have a hydrographic survey company come to your location at once to survey the area and explain to you how they would map the region. The team will use their own boats and equipment to ensure that they have taken the right images, and those images will be used for your building plans. You can even go back to your surveyor in the future if you need to have your maps refreshed or redrawn due to current and coastal erosion.
