Conducting a hydrographic survey is the most accurate way to analyze and map the floor of a body of water. The conditions of a water floor can be turbulent. It is important that the survey be done correctly the first time to avoid any mistakes that will require additional work to accurately map the water floor. The following should be kept in mind when conducting a hydrographic survey:
Be fore you begin your survey, thoroughly check all of your equipment. Make sure your boat's gas tank is completely full and you have fully charged all of your batteries. You do not want to be in the midst of your survey only to have to scrap the entire process because your equipment is not prepared. Also, make sure all of your data is loaded into your computer system. Your data should include the track lines that your vessel will be following, the outline of the water body, and the quality control measures are in place. Be certain that you are aware of anything that can obstruct the survey, including sand bars or bridges.
Follow Your Track Lines Carefully
The track lines are crucial to the survey process, so it is important to follow them as closely as possible. You should run your boat as close to your track lines as closely as you can in order to obtain the most accurate results.
Keep The Boat Close To The Wall
Seawalls are very important to the accuracy of the data you will collect during the hydrographic survey. Your boat will need to remain as close to the seawall as possible during the process. Do not be tempted to crisscross from one corner of the waterway to another in order to save time, particularly on longer waterways. While it can be tempting to do so, you are risking the accuracy of the shoreline data, which is among the most important that you will collect.
Avoid Waiting Too Long To Process Data
Once the survey has been completed and you have collected all the necessary data, it is crucial to process it as soon as you are finished. Waiting too long to do so can have a major impact on your results. It is also important to expedite the data processing in case you have to collect additional data in order to complete the survey if certain information you need is missing. The bottom of the waterway can change significantly if you wait too long to process the information, which can render your hydrographic survey practically useless and will require a new survey to be completed.
When you are working on a hydrographic survey, it is important to be patient and take your time. Having more data than you believe you will need is much more useful than not having enough. Contact a pro, like Abbott's Construction Services Inc., for more help.
