Difference between drone surveying and manual land surveying.
Surveying is a means of making relatively large-scale, accurate measurements of the Earth’s surfaces.
Land Survey involves the scientific process of measuring the dimensions of a particular area of the earth’s surface, including its horizontal distances, directions, angles, and elevations. Artificial structures, such as a road or building, may also be noted during a survey.
A Drone Survey refers to the use of a drone, or unmanned aerial vehicle (UAV), to capture aerial data with downward-facing sensors, such as RGB or multispectral cameras, and LIDAR payloads.
What are the Differences?
- Capturing topographic data with a drone is up to five times faster than with land-based methods and requires less manpower. With PPK geo-tagging, you also save time, as placing numerous GCPs is no longer necessary. You ultimately deliver your survey results faster and at a lower cost.
- Drone maps created using good quality drone equipment, careful flight planning, commercial grade GPS ground control points and commercial grade processing software can potentially be accurate to around 2-3cm horizontally and around 5-6cm vertically.
- Compared to other surveying methods, drone surveys can be completed in less time, as drones are able to cover large areas of land within a short period.
- Typically, drone surveys can produce high-quality photographs and video recordings in a couple of hours.
TRADITIONAL LAND SURVEYING
- While drones are agile and reliable, they can’t deal well with high winds. Drones are lightweight and small; high winds can blow them off course and make it impossible for them to get consistent readings. This is unlike traditional Land surveying equipment and instruments which are tethered to the ground.
- The brick-size batteries used by drones are heavy and can get used up quickly unlike total stations which have better battery capacity. Although “the newer the model, the stronger the battery” according to Our In-house GIS Analyst, Mr Boluwatife Williams.
- Traditional methods involve staff manually traversing a site to collect data points, whereas drones can collect this data with staff far away from potentially dangerous areas.
- Manual surveying methods are incredibly accurate, the accuracy of the drone surveying is only threatened if the pilot is a greenhorn.
7 Tips For Maintenance Of Surveying Equipment
Surveying equipment is used under the most stressful conditions. They are exposed to extreme weather conditions, used in dusty construction areas and subject to bumpy transportation.
Adequate care and maintenance of the equipment, proper storage and good transportation are major factors in the successful completion of a survey.
Lack of good maintenance practices not only causes unjustified replacement costs but also can seriously affect the efficiency and accuracy of the equipment and the entire survey.
The list of surveying equipment includes:
- Measuring Tape
- Level and Rod
- 3D Scanners
- Total stations
- Electronic measuring devices
- GPS receivers and more.
These surveying instruments are designed to provide years of reliable use. The shafts, spindles, pendulums, and electronics of precision instruments, although constructed for rugged field conditions, can be easily damaged by careless acts, mishandling and continued negation of prescribed procedures for the use and care of the instrument.
MAINTAINING SURVEY EQUIPMENT
Each new instrument is furnished with an operator’s manual. The manual contains a description of the instrument, specifications of its various components and capabilities, and applications. The manual also contains basic instructions for use of the instrument and describes recommended servicing and adjusting methods. The operator’s manual should be kept with the instrument at all times. Each operator should thoroughly study the manual prior to the use of the instrument, particularly whenever prescribed field adjustments are to be made
Some general principles of care, maintenance and servicing should be applied routinely matter for all survey equipment and supplies.
- All equipment and tools should be kept clean and dry, particularly if they are to be transported or stored for any length of time.
- Equipment should be wiped clean of dry mud or moisture prior to returning the equipment to the vehicle. The original painted or varnished surfaces should be repaired as often as needed to keep moisture from entering the wood.
- Metal surfaces should be cleaned thoroughly. A coat of light oil should be applied to tapes and the metal parts of tools to prevent rusting during storage. Excess oil should be wiped off.
- Before making the first set-up of the day, visually inspect the instrument for cracks, bumps, and dents. Check the machined surfaces and the polished faces of the lenses and mirrors. Try the clamps and motions for smooth operation (absence of binding or gritty sound).
- DO NOT loosen or attempt to clean the internal surface of any lens.
- Leave instruments in the case when it is not being used for any length of time, particularly if there is dust or moisture in the air. After an instrument has been used in a damp or extremely cold situation, special precautions must be taken to prevent condensation of moisture inside of the instrument. When working with the instrument in cold weather, it should be left in the carrying case in the vehicle overnight. If stored in a heated room overnight, the instrument must be removed from the carrying case. If the instrument is wet or frost-covered it should be removed from its case, and kept at room temperature to dry out.
- Transport and store instruments in the right positions. Many instrument cases indicate the position in which they should be transported. Always transport the instruments in their carrying cases placed in a compartment cushioned firmly to protect them from jolting or excessive vibrations.
GIS FOR BEGINNERS.
A geographic information system (GIS) is a tool for collecting, organizing, managing, manipulating, analyzing, storing, and presenting many types of spatial data.
Sounds encompassing, right? How does this tool affect me as an average person? Anyway, it isn’t until I go to colleges or universities to study it and maybe probably because it’s in the line of my job or career choice.
Surprisingly, most all individuals on earth are already using or embedded into the almighty GIS circle in their daily lives and activities without spending tuition or intentional learning it or deciding on a career path in it.
GIS is Applicable in the following areas:
GIS has been a tool used to provide a visual presentation of data that I and most people use in everyday navigation processes, location intelligence and analytics, parcel delivery and tracking, rescheduling deliveries, and finding where and when in respect to what distance or position.
Banking has evolved away from the ancient systems of “I can only send funds or perform transactions in my physical location or a bank branch where I opened an account.” Through the application of a tool that has enhanced smart planning, organizing, data transfer, data storage, and swift decision-making in the banking industry, people can make secured transactions with their bank accounts from their comfort zones to other people in far countries where their preferred bank may not even have a branch.
- Telecom and Network services.
According to Statista in 2022, including both smart and feature phones, the current number of mobile phone users is 7.26 billion, which makes 91.54% of people in the world cell phone owners and users. These services use GIS to enhance their processes through better data management and location services.

- Disaster Management and Mitigation.
Efficient GIS systems protect the environment and are developed to assist risk and disaster management in different locations across the globe. This is done by developing tools used to measure risk factors. Refer to our previous blog post on How GIS can be used to estimate flood damage.
Airports manage their fleet of aircraft, make flight plans, organize schedules, estimate arrivals and departure times, and know when the weather is favorable to fly to other destinations by incorporating GIS in their repertoire of tools and systems.
The use of GIS has a profound impact on agriculture or the food value chain, at least on all humans, educated or non-educated, poor or rich, young or old depending on the food.
Local farmers might not be vast in the use of technology but they use pesticides, and fertilizers, to export their farm produce. Though they might not directly apply the tool themselves in those processes, they are embedded in the system for the dream and accomplishment of a farmer is to grow and nurture healthy farm produce in good yields, feed on, distribute, supply, and sell to others. GIS is directly or indirectly used in all the processes of getting food to the table.
Surveying involves measuring the position of objects on earth, below the earth, in water, and in space through field procedures and the use of various equipment or tools: GPS, total station, compass, measuring tape, UAVs, and many others. The data gotten from field observations are incorporated into a GIS system which calculates, estimates visualizes, and prepares digital maps, plans, graphs, and charts for understanding, decision making, and implementation purposes.
The inestimable value of GIS in deciding many life and living factors cannot be over-emphasized. In every way, GIS presents a much more calculable way of making life easier.

The Impeding Progress of Land Tenure System
Mr. Taiwo Adeniran, Surveyor-General of the Federation, spoke about the incapability of unleashing private sector-led entrepreneurship and critical development needed in Nigeria due to the current land tenure system practiced in Nigeria.
Adeniran made this known during the delivery of a paper titled: ‘Surveying Practice in Federal Capital Territory: The Burden of Land Tenure System and Lack of Adaptability to Change’, at a seminar organized by the Association of Private Practicing Surveyors of Nigeria (APPSN).
He also stressed that the Land Proclamation Ordinance validated by Lord Lugard in 1900 disregarded the principle of native law and customs, and provided that title to Land can only be owed through the high commissioner.
Adeniran concluded that the ordinance was approved to kill the institution of family and communal land ownership by facilitating the acquisition of title to land through the high commissioner.
While also criticizing the Land and Native Rights Act of 1916, Adeniran said the present land ownership system in Nigeria as enshrined in the Land Use Act of 1978 had its origin in the 1916 document enacted in the North by the colonial masters.
He said, “This shows the colonial socialist inclinations with excessive state control of land ownership, use and development”.
And cannot effectively aid private sector-driven enterprises and development initiatives, because of the creation of too many bureaucracies in the documentation of Land transactions, registration, and titling.
“The support for people empowerment is not encouraged due to the lockup capital in the land system”. Posing as a burden on the practice of surveying in the FCT as the government is the major user of the practicing surveyors’ services.
“And for this course, a call was made to revoke the Land Use Act of 1978 and the introduction of Land Reform in 2007.”
Adeniran said the United Nations won’t achieve its 17 Sustainable Development Goals (SDGs) by 2030 without surveying and geospatial inputs.
And so advised surveying professionals to develop geospatial solutions in facilitating the realization of goals. In order to analyze the environment and prepare a proposal for government institutions that may want to deploy the innovations.
He urged “Surveyors and geometricians to think about solutions because surveying and geomatics are about solutions. Our major problem is that we wait for people to create jobs for us, whereas we have to create it and provide solutions for it,” he said.
The lack of understanding of issues by political leaders was pointed out by Layi Arinola, Chief Consultant, Arinmap Consultants, and advised stakeholders to come together to save the surveying profession in Nigeria, which, according to him, is slowly diminishing.
On his own, the FCT Chairman of APPSN, Solomon Olukotun, in his welcome address, disclosed that surveying practice in the FCT does not lack the requisite efforts from major stakeholders, but inadequate funding from the authorities.
