Difference Between Land Surveying and Mapping

Before GPS technology was invented, land mapping was manually done by collecting data from a specific land area. Cartographers had to spend hours to complete maps back in the day but today, advancement in technology has made a great impact in making land mapping more time-effective and easier.

Land surveying involves all activities that record and measure all information in our physical world as well as the environment. The term is used interchangeably with Geomatics—a body of science that involves pinpointing the position of things above and below the surface of the earth. Mapping is a part of the land surveying process. It uses specialized technology, mathematics and mapping equipment.

The role of a land surveyor is to determine and mark different locations on a certain land. This is used in surveying boundaries of certain real estate properties in order to find out their specific coordinates. Land surveyors come up with three-dimensional or 3D positions and distances of angles between them.

Out in the field, the land surveyor use GPS, aerial/terrestrial scanners or Robotic Total Solutions to map a certain area of land. They take photos and make computations. In the office, they use sophisticated software such as AutoCAD to plan and draft their measurements. They work on a variety of projects that involve mining exploration, land division, tunnel building, land size determination and measurement. They are also responsible for providing specific information about a land to guide the work of architects, land developers and engineers.

Advantages of 3D laser scanning survey over other survey techniques

The new age 3D surveying techniques comes with various advantages and one of the few being the speed of processing and its versatility.  This kind of survey has become more advanced and easier than the other surveying techniques.

The world of surveying has changed drastically over the years. While earlier, it used to take months to complete a survey and another few days more to churn in the reports, the advancement in tools and technology has made the process faster.
Now, with the 3D technology at the realm of surveying, the process has gained a faster pace and the complications involved has decreased tremendously.

The 3D survey can be beneficial in various ways, and three essential factors among them are its versatility, speed and also the effortlessness. Let us work it out with an example here.

Say, for instance, the government is contemplating building a bridge over the river or a road over the mountains. Since surveying is a primary need of such projects, it might take at least half a year to complete a topographical survey by normal methods. And, the physical efforts needed or the hands required, will, definitely, be enormous.

 On the other hand, with the 3D laser technology, such surveys, can be done with the help of few people, with much less physical effort and with 100% accuracy.

The 3D technology, is highly versatile too. It can be adopted for any kind of survey, be it topographical, environmental, the ALTA surveys and what not. The surveys can also be done irrespective of the position of measuring points or the condition of a building or its safety features.

Hence, if it comes to a fool proof, faster and easy surveying, the 3D laser survey takes a whole lot of brownie points than the other traditional methods.

Land surveying techniques that are approved by the government of Arizona

Land surveying is one of the primary requirements for either getting a bank loan or for approval of your projects by the government. For instance, if you are planning to purchase a property in Arizona, and would like to be sure about its boundaries on either side, it is necessary to have it surveyed. Hence, today, almost every property in places like Arizona is bought with the proper land mapping, to avoid surprises later on. There are several techniques that are approved by the authorities of land surveying agency in Arizona.

The surveying agencies working under a particular state need to know the land policies belonging to the state, and also follow up the guidelines to report a survey. Hence, it is always a wise move to employ only those surveying agencies which operate within a state. Although the guidelines laid by the land authorities may work out to be the same, a slight change from one state to another is quite reasonable. So, if you are planning to buy land in Arizona, finding the best surveyor in that area can work out to be a good decision.

Today, the way a surveying agency operates and the time to submit a report has changed tremendously. Unlike the earlier days, when one land survey used to take days or even months together, things are done at a faster pace presently. With 3d and laser techniques, the surveying agencies can perform a complicated and most impossible survey too, at a very short time. The automatic reports, that they produce, are accurate and precise, making this technique all the more advanced and trustworthy.

That is the reason, for any land dispute, the first thing the court authorities ask for, is a land surveyor report. Hence, having a proper mapping of your property can work out to the best of your advantage for a long time.

Use Laser Scanning Survey Services To Get Enhanced And More Precise Measurements Of Data

We have heard of laser technology often enough now. However, how can it be related to the land acquisitions and topographical survey?

Well, when one can combine all the sciences together, to bring about changes, why not topography and laser? The laser technology, which has been used so far, in the medicinal field and so on, has brought about tremendous changes in topography and environmental surveys too.

According to the experts in the field of property development and valuations, the laser survey has worked to be a boon to an otherwise tedious process. There are some tremendous benefits attached to laser surveying techniques.

Faster Results

Earlier, a topographical survey of any land, irrespective of its size, would mean spending hour’s together or even days sometimes, to get the accurate data. Laser surveys are computerized surveys, which needs just a few hours to complete the data. The results or the reports, thus, can be printed immediately since it is fed in the computer.

Greater Accuracy

Once you perform a laser survey, you need not come back again to the site, to check out if you have measured a particular point correctly. The accuracy and precision of such surveys are just mind-boggling.

Less Manpower, So Reduced Cost of Operation

Usually, traditional land surveying used to involve quite an amount of hard work. This would mean hiring out innumerable people to work on a particular project. The technology for laser scanning does not require either more hours or people to perform a function.

Using laser scanning techniques for surveying your land, thus, can give you much enhanced and precise results.

Eliminate the probable risks of ecological hazards with Environmental survey

There is a growing concern among everyone in the industrial world and researchers, regarding the health of our environment. Since it is highly an accepted fact, now that one cannot play with our nature anymore, and destroy it further, stringent conditions are now laid down for tackling all those who try to put a hamper to the real efforts of the protecting agencies. The environmental surveys, therefore, has become a priority before starting up an industry or setting up a business.

It is not only the environment that one is concerned about. Many a times, environmental factors, such as the presence of a particular population of flora or fauna in the neighborhood or even a water body, can cause detrimental effects, if not monitored or taken precautions.

Thus, recording the essential factors involved, and any potential environmental hazards, can help in adhering to every condition laid down by sanctioning bodies. This fact can, further help the industry or a business house in dealing with issues or show-cause notices that the approving authorities might send and also to avoid possible risks due to ecological impacts.

The environmental surveys work both ways. It can help you to protect your investment, by helping you monitor ecology and environment of the surrounding areas. Moreover, it can also check if your property is going to harm the ecological balance in any way. Hence, one such survey, done by an authorized agency, can protect you from legal implications alter on and safeguard your investment.

Although the reports or the points included in these inspections are almost similar worldwide, the reviewing agencies operate, keeping in view of the local or state environmental rules. This way, you can eliminate all possible consequences, if any, in the future.

Environmental surveys, therefore, are very much essential and integral part of any project you are starting out with, to prevent any effects to the surroundings or harm to your property.
