Land surveying and geomatics engineering are similar but different jobs in the field of land management. Know the difference so you can confidently hire the right expert for your project.
Basically, you need a land surveyor for any type of legal land survey. You need a geomatics engineer for anything else that uses technology and involves a physical location. Both jobs start with the same education: either a university degree in geomatics engineering or a technical school diploma in geomatics technology.
Graduates wishing to become land surveyors get their education certified by a national board. Sometimes, this means more training. Land surveyors, geomatics engineers, survey technologists, geomatics technologists and design technicians work together on a project to operate the instruments, collect and interpret the data, and prepare the documents.
However, only a land surveyor ALS can validate legal land survey documents. Both the origins are Canadian but had completely different intents on their definitions of Geomatics and GIS. In the early s, Dr.
In fact, the Canada Land Inventory CLI helped determine land capability for rural Canada by mapping data related to soils, agriculture, forestry and land use. Canada is the second-largest country in the world.
Because of its sheer size, paper maps and analysis were cumbersome and inaccurate. The CLI managed soil, drainage, and climate characteristics on the Canadian landscape. Because the CLI data determined land capability for crop types and forested areas, it became a key decision-making tool for land use in Canada. CGIS was unique because it adopted a layer approach system to map handling.
Since this period of time, GIS has evolved into a computer-based tool for storing and manipulating map-based land data. The term Geomatics that Paradis wanted to convey was to encompass how modern technology data acquisition was becoming commonly involved in disciplines such as surveying, photogrammetry, geodesy and hydrography.
Basically, it encompassed various methods and tools from data acquisition to distribution. In , the Laval Surveying Department in Quebec, Canada developed the first academic program in Geomatics in the world. Actually, it replaced its current curriculum in surveying. Geomatics is a scientific term for gathering, storing, processing, and delivering geographic information.
Also, it is an umbrella term for every method and tool from data acquisition to distribution including math, computers, and Earth science. In the U. The study of geomatics also incorporates mathematics, computer science, and engineering. Geomatics engineering combines the use of spatial information with the practical application of scientific and technical knowledge. In the broadest definition, geomatics deals with measurements in the context of the Earth; however, to plan and complete major infrastructure projects, engineering firms need more than just data.
They use accurate spatial information combined with other technology to make decisions and arrive at the optimal approach to any project. Applying geomatics tools to solve real-world problems requires an intimate knowledge of both the problem and of the geomatics technologies available. The study of geomatics prepares students for job opportunities in an expanding number of industries that use geospatial data, such as oil and gas, space exploration, environment, engineering, architecture, and facilities management, and non-traditional fields such as health and finance.
A person with this integrated knowledge can help almost every industry to become more accurate and more efficient, with better faster solutions. As our reliance on geospatial information in our daily lives continues to increase for everything from navigation to national security, geomatics experts will be in demand on a global scale.
Before , few classes crossed over between the individual engineering and surveying practices. With new capabilities in software and technology, integrated coursework leading to an awareness of how the specialties relate to each other is increasingly valuable.
By creating a holistic approach to geomatics education, as well as improving the process to establish credentials, higher education institutions are producing well-rounded professionals with the ability to perform services and advance scientific development in all interrelated areas. The power of GIS lies in the ability to view and analyze multiple data layers in relation to one another.
In addition, the software can be used to create more spatial data by digitizing roads, buildings and streams viewed on maps or imagery. Relational databases are useful for answering queries to extract information from the data. For example, to select a location for a new retail store, the company may query the database to extract all areas that meet a certain criterion for population and average household income.
There is more geographic data available today than ever before, thanks to high-powered scanners, robotic total stations, large-format aerial cameras, satellites, drones, etc. Without geographic information systems, managing this large volume of data would be an impossible task, and the full value of the information could easily be overlooked.
Land surveyors use GIS to improve efficiency and facilitate project planning before they start. Reviewing zoning, road networks and environmentally sensitive areas or researching historical maps can be part of the pre-field work investigation. During a project, surveyors use GIS to monitor progress of their own data collection efforts to avoid data gaps.
