It is a high-definition survey technique that provides faster and more accurate results compared to conventional survey methods. A 3D high definition surveying service is beneficial for builders, engineers, architects, and project developers who need accurate information on land that has already been constructed on but may need to be further examined for destruction, renovation, remodeling, and other reasons. This surveying method is ideal for projects in any developmental stage, like planning, initiation, upgrade, and conclusion.

HD 3D surveying utilizes an updated scanning system that is highly accurate, flexible, and swift. It works with specially developed software for an easier way to view scanned 3D images. Software should provide panoramic views, measurements, and markups. High-end 3D surveying can provide 360 by 320-degree photo-realistic panoramic scans of the property, so you can have more precise and exclusive 3D images.

Working with a reputable 3D surveying service provider will allow you to create and update as-built documentation. This surveying method is helpful in assessing the condition of a property and any damage it may have. Advanced 3D surveying methods can exchange data with several CAD platforms and create 3D models semi-automatically. The method is ideal for clash and interference checking and useful for making 2D plans, too. This way, 3D surveying results can be useful for applications like inspections, deformation analysis, vessel/tank volumetric information, and weld peaking reports.


Reputable 3D laser scanning service providers can cater to a variety of businesses, government entities, industries, and residential clients who want a quicker and accurate way to survey their land and property. This way, 3D surveying can simplify the construction and upgrading process using cutting-edge technology. The survey method is capable of scanning large areas quickly and accurately, enabling you to save time and effort, and minimize disruptions in the job site.

Difference Between ALTA/ACSM Lands Title Survey and Boundary Survey

ALTA/ACSM land title surveys are also referred to as 'due diligence surveys', and they are conducted for commercial purposes. They are different from a conventional boundary survey where only easements, property lines, and other data as mandated by a state standard are shown. ALTA/ACSM surveys follow a uniform set of codes for construction purposes as set by authorized institutions and the government.

A boundary survey merely establishes the corners of a land or a residence. On the other hand, an ALTA/ACSM survey is required along with other important documents when going through any transaction involving commercial real estate. It is often included as part of the insurance or title certificate application. ALTA stands for 'American Land Title Association', and ACSM stands for the 'American Congress on Surveying and Mapping'.

The ALTA/ACSM standards require a highly detailed report that will include the easements encumbering or benefiting the property, zoning setbacks, possible encroachments across easements and boundaries, and flood zones that could affect the property. The survey may show whether there is any access to public roads, evidence of use by any other parties, evidence of cemeteries, water boundaries, and the names of the owners of an adjoining property.

Prior to measuring the property, professional surveyors do some in-depth research on it. This is done by examining the existing title commitment and searching for country and municipal records for any existing encumbrances. The research will provide surveyors with knowledge of the land, and will inform them of any possible conflict before doing an ALTA/ACSM land title survey.


An ALTA/ACSM survey may provide more information that is crucial to commercial real estate projects and transactions. It can suggest improvements on the land, like roads, fences, rights of ways, and trails. It can provide further improvements, ownership areas, easements, and encroachments on the property and its boundaries. The survey may provide information on the on the property.

Uses & Applications of Topographic Land Survey

There are many different types of surveys such as residential surveys, boundary surveys and topographical surveys. In this article we will explain the type of results you get with a topographical survey, their uses and applications.

A topographical survey allows you to establish the natural and man-made features of a certain land. The results of a topographical survey can be beneficial for property owners, industrial owners and owners of properties under construction because it includes the hills, trees, buildings, fences, ravines or any improvements being made on the natural features of the land. It provides us with the exact figures in terms of position, height and size of the different changes that have occurred in the land as far as its natural existence is concerned.

Remote sensing techniques and arial viewing of the land help topographic surveyors come up with accurate details while the map is being created. They use symbols colors and signs to designate details on these maps. Topographic surveyors make sure that the maps they create are as accurate as it can get.

For topographic land survey to be carried out, special equipment such as electronic laser stations need to be used by professional surveyors. The equipment used vary in accuracy. Surveyors also use GPS or Global Positioning System to get instant access to the National Grid coordinates available. Other standard equipment includes laptop computers, Distos and digital levels.

To achieve their objectives, surveyors need to use elements such as physics, trigonometry, engineering, law and mathematics.

High Definition Surveying and Its Utilities

High definition surveying can be a practical way to collect as-built data accurately and rapidly. It is a non-invasive method that utilizes a 3D laser scanner, which emits an eye-safe and narrow laser beam that can cover any size or type of object—from buildings to bridges and vacant lots. Through HD surveying, land surveyors are able to gather data more conveniently in a matter of minutes. The measurements are gathered and grouped into a complete point cloud database, which can be viewed, altered, or manipulated on a computer. The data is viewable, analyzed, and viewed like a 3D model made in a conventional CAD program.

The technology behind high definition surveying is considered the most advanced and highly updated among typically used land surveying techniques. High definition surveying offers a swifter and more accurate way to collect data and measurements, making it useful for builders, constructors, architects, engineers, and project developers. With HD surveying, those professionals can accurately survey land, even if it has already been constructed. The survey can be useful when a structure or land must be examined for remodeling, renovation, destruction, or for other purposes.

The methodology for HD 3D laser surveying involves a high-end and versatile scanning system and user-friendly software. This method of surveying can take 360 by 320 degree photo-realistic panoramic scans, too, so surveyors can have precise and exclusive 3D images for reference. High definition surveying is offered by experienced and reputable land surveying companies.


High definition surveying is practical for a number of applications. It can be used for creating and updating as-built documentation, data exchange with various CAD platforms, condition and damage assessment, deformation analysis, and clash/interference checking. It can be used for generating 2D plans, too. 3D survey results may help land inspections become more productive and reap better results.

ALTA/ACSM Land Title Survey - Various Applications and Advantages

The ALTA survey is typically required to be submitted with other documents during commercial real estate transactions. It is the land title survey that is usually referred to as a section of a title certificate application or insurance. The survey must be performed according to the standards and specifications of the ALTA/ACSM. ALTA stands for 'The American Land Title Association', and ACSM stands for 'The American Congress on Surveying and Mapping'. ALTA surveys aim to promote nationwide uniformity and standards in land survey data.

ALTA/ACSM land title surveys are beneficial to title companies, corporations and lenders, contractors, engineers, architects, and the general public. The ACSM and the National Society of Professional Surveyors created accuracy standards for dealing with issues like closure and distance requirements and minimum angle and positional uncertainty for ALTA/ACSM land title surveys. The survey can provide the most comprehensive and accurate information to the title company before the title is insured to the property.

An ALTA/ACSM land title survey typically bears the full names of concerned parties, such as the buyer, seller, lender, insurance company, and Title Company. This survey may be practical for homeowners, too. Hence, it is important that both title insurance and land surveying companies work closely together to make sure that the ALTA/ACSM survey can be useful when resolving matters that may affect land ownership.

Also known as 'due diligence surveys', ALTA land title surveys clearly depict improvements and easements, ownership areas, rights-of-way, encroachments (if any), encumbrances, the boundaries of the property, and other important aspects pertaining to ownership of land. ALTA/ACSM surveys may be used as a basis for ideas when there is a need to improve the land with trails, fences, rights of ways, and roads. They may provide information that may require more investigation especially when there is a possibility of adverse rights on the property.

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 Auto CAD 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.
