How Modern Technology Improves Topographic Maps

Topographic surveys, sometimes called "topo surveys" for short, show not just the contours but the
terrain, elevation, and natural and man-made features of a parcel of land. They have been used for
centuries by engineers, architects and other designers to decide what kind of construction is best fitted to the land, and what changes may need to be made to build on it. While historically surveyors used various optical leveling instruments to make a topographic map, the modern Los Angeles topographic survey employs more high-tech solutions.

An aerial topo survey is one of the most useful innovations. These surveys are performed by taking
photographs in an airplane or helicopter at a specific distance from the ground. Multiple photographs
are taken from different points over the land. Then the elevation is calculated by comparing pairs of
photographs to create a kind of 3-D perspective, the same way our depth perception works by seeing
the world through two eyes.

However, aerial surveys are limited in how accurate they can get, so sometimes a Los Angeles
topographic survey must be performed on the ground. The surveyor walks over the entire land, taking measurements at specific intervals depending on how precise the survey needs to be. Modern surveyors use survey-grade GPS equipment. While the commercial GPS in your car or cellphone may be accurate down to a few feet, a survey-grade GPS, when carefully calibrated, can be accurate down to a few centimeters, or even millimeters if it's kept stationary for a period of time. Survey-grade GPS units also calculate vertical as well as horizontal location, measuring the exact height of a particular point.

Having a good topographic map is essential in starting any major construction project. Whatever purpose it's going to be used for, modern technology can ensure that a Los Angeles topographic survey is accurate down to as precise a degree as a designer needs.

Qualities to Look for in a Land Surveyor

Building something can be an exciting process, even if it is just an addition on your lovely Southern Californian home. Before you can start building you will have to hire the services of a land surveyor. If you are like many people, you will probably have no idea where to start. There are a few simple things to look for when searching for a Los Angeles land surveyor.

A competent surveying company will be able to provide references and referrals from past clients. This is a sure sign that you have found skilled professionals. Their references can tell you how timely and thorough they were. Since breaking ground could be on hold until surveys go through, it is important that the company you choose can work efficiently.

Another quality you should seek in your surveyors is up to date equipment. A company that keeps up with technology can give you the most accurate readings of your land. It also indicates dedication to the industry if a company invests in top quality equipment. You should also make sure that the company you hire has all kinds of insurance, including liability and workman’s compensation. Having insurance will protect you, the consumer, from any accidents or unforeseen circumstances.

Finally, the company should be local to your area. Hiring a Los Angeles land surveyor is important because they will know the local laws and regulations. They will have dealt with the local government and, therefore, will be of help to you and your project.

 Do not be daunted by the idea of hiring a land surveyor. If you can find a company that has all the above qualities, you can trust that they are professionals who know what they are doing and can help you. Southern California is a beautiful place to live and raise a family. Expanding your home could be a more affordable and easier option than moving into a large house. If this is the case, finding a Los Angeles land surveyor you can trust will help you get the job done.
