Accurate and Efficient: How Drone Mapping and Site Plan Overlays Improve Land Parcel Demarcation

Land parcel demarcation is crucial in real estate development and land management. In the past, traditional surveying methods, such as measuring tapes, total stations, and theodolites, were used for this purpose. However, with the introduction of drone technology, land surveying has become more accurate and efficient.

Drone mapping, also known as aerial surveying, uses unmanned aerial vehicles (UAVs) to capture high-resolution aerial images of land and its surroundings. These images are processed to create detailed maps and 3D models that can be used for various applications, including land parcel demarcation.

Recently, we helped our client visualize their property boundary as per their survey plan onto a precise map generated with our drone mapping solution and site plan overlay using GIS. The map has a 1.5 cm GSD (Ground Sample Distance) or pixel resolution, providing high accuracy and detail.

One key benefit of drone mapping is its ability to produce highly accurate and detailed maps. Drones have high-resolution cameras that can capture images with resolutions as high as 1 cm per pixel, resulting in minimal errors in the maps created.

Another advantage is that drone mapping is faster and more efficient than traditional surveying methods. Drones can cover large areas of land in a short amount of time, reducing the time and resources needed for land surveying. This allows for quicker land development and management.

Site plan overlays can also be used for land parcel demarcation. These overlays involve combining maps and other data onto a site plan, providing a comprehensive view of the land and its surroundings. Information, such as property boundaries, topography, vegetation, and infrastructure, can be included in site plan overlays.

By combining drone mapping with site plan overlays, land surveyors can create highly accurate and detailed maps that provide a comprehensive view of the land and its surroundings. This is particularly useful in complex land demarcation projects with multiple land parcels with varying boundaries and terrain.

Drone mapping and site plan overlays are cost-effective solutions for land parcel demarcation. Traditional surveying methods can be expensive, requiring expensive equipment and trained personnel. In contrast, drone mapping and site plan overlays require minimal equipment and can be completed by a small team of trained personnel.

In conclusion, drone mapping and site plan overlays are highly effective tools for land parcel demarcation. They provide highly accurate and detailed maps, are faster and more efficient than traditional surveying methods, and are cost-effective solutions for land development and management. Using these technologies, land surveyors can provide accurate and efficient demarcation of land parcels, contributing to more effective land development and management.

Drone Applications in Real Estate.

Drone technology is among the most disruptive technologies of our time. Mining, surveying, health care delivery, industrial inspections, environmental monitoring, and many more industries are adopting this technology rapidly. Real estate has become a stronghold for drones. As a result of their various benefits, drones are revolutionizing the way real estate projects are planned, monitored, implemented, bought and sold. The following are some of the benefits of drones.

Real estate marketing.

Location! Location! Location! A property's location is the most significant factor in its valuation. A drone can capture aerial footage of a property from a high altitude, showing the surroundings as well as the property itself. This includes road access, scenic landscape, prominent landmarks, shopping complexes, and parks. Labels can also be used to highlight their details and positions in the image. A simple layout of the area can be created with high-resolution imagery and corresponding labels. This will especially benefit when a large property is being split into several smaller parts before being sold. Each piece can be labelled and listed online with its location and dimensions, making it easier for buyers to decide between pieces. 

Drones provide a unique perspective on properties listed on online portals. A single frame gives buyers an overview of the dimensions of assets such as a swimming pool, patio, garden, walkways, etc.

Video tours of a property can capture a potential client's attention for an extended period. It is very common for buyers to look at aerial images of locations before visiting them in person to get a clearer picture of the place. In this case, real estate agents benefit because buyers can fall in love with the property before they even visit it. 

Scaled map of the property

Using aerial photogrammetry, we can generate a precise orthomosaic of the data collected. An orthomosaic is a scaled map of the property that can be used for planning and drawing. Any institution that leases out open spaces will benefit from this feature, especially the hospitality sector. Traditional photography cannot capture the entire property in a single image. Drones can follow a predetermined path to capture images. The multiple images are then stitched together to create a single large orthomosaic covering the entire property area. An orthomosaic showing the boundaries of spaces leased out with labels on them would greatly assist their clients in choosing the most suitable space in the property that is suitable for their needs. 

Interactive 3D Models

A UAV is a perfect tool for the 3D modelling of buildings. Spin, rotate, and manoeuvre around your model with impressive detail and clarity. Gain deep insights into your project and visualize it from previously unseen angles. Make advanced measurements and calculations on your model. Select points to measure the area of a rooftop, the distance between points, and even the volume of a stockpile. Creating a 3D model of the surrounding area can be a great way to put your development in context. 

Not just individual buildings, we can model entire city blocks! This data can then be used by architects and engineers for future designs, additions or alterations, by councils and heritage registers for records of current building condition, or by inspectors to assess the condition of the building in high detail without the need for specialist safety equipment. 

These models are also used for assessing risks (i.e rockfalls, cliff failures etc) that may cause a safety hazard, designing structures (i.e retaining walls), and inspecting inaccessible areas .

A drone can easily assess the condition of hard-to-reach areas like building roofs. Using drones, high-resolution images can be obtained of roofs.

Monitoring of property

Planners, architects, and construction contractors can use drones to capture site data over time to create progress reports and analyze how the site plan is being implemented. It is accomplished by superimposing the site development plan over the orthomosaic generated at various times according to the needs of the project. 

A drone service provider can provide homeowners with up-to-date aerial footage of their properties to help them assess their conditions and monitor any other concerns they may have such as trespassing by neighbours while they are away. By capturing footage from multiple angles, drones can provide complete coverage of the property's assets.

Cost-effective.

By integrating technologies such as artificial intelligence and GPS-enabled flying, drones capture data in the most efficient way with the minimum amount of manpower and in a shorter time frame.

Creating a Orthophoto Map from Aerial Imagery captured with a UAV(Drone)

The purpose of a map is to represent the earth's surface so that you can measure dimensions, directions, areas, etc, as opposed to using aerial photographs that have distortions. An orthophoto (a geometrically correct aerial image map) was created from a single aerial image captured with an unmanned aerial vehicle (drone).

The drone image has a very high resolution as compared to the satellite image. Imagine if we could use this data to directly measure dimensions from an image. This is exactly what we did.

Once the aerial image was processed and converted into an orthophoto, the orthophoto was overlaid onto the satellite image and we found excellent results when measuring the dimensions. According to the institution, the size of the ground is 100m x 68m which we have measured with centimetre accuracy using our orthomosaic map. You can see it below.

Electricity is one of the basic human needs of modern society. In our villages, we have electricity distributed through overhead electrical wires mounted on poles equipped with street lights. Many times, the lights don't work and monitoring them becomes a hassle due to their number and close proximity between neighbouring electrical poles. Each pole has a unique pole number. Panch members and the villagers would benefit greatly if they could report their grievances by stating the pole number. The electrical staff and the panchayat members could subsequently refer to the pole distribution map made available to them. GIS can also be used to track one's position with respect to the village map. This is done using mobile phone GPS and a base map of the electrical pole distribution overlaid on satellite imagery.

Optical fiber network mapping to enhance business operations, reduce capital expenditures, and increase customer service.

Geographic Information System (GIS) is a computer system used to store, edit, analyze and display geographically referenced information. This system utilizes GIS to map out where Fiber Cables are installed and used in order to provide valuable information to telecommunication companies for more accurate planning for new fiber network and seamless management of the entire integrated infrastructure. Staying competitive in the modern fiber optic development space is hard without a Geographic Information System (GIS). GIS platforms enable fiber network managers to create high-quality digital representations of their networks, run data queries, troubleshoot issues, and plan for future growth. 

Fiber Maps Defined 

A visual representation of a fiber network is called a “fiber map.” 

GIS fiber mapping is essential for the following reasons: 

• Understanding how all network components work together
• Revealing spatial distribution and growth opportunities
• Identifying network vulnerabilities 
• Improving system analyses

Understanding your network 

When it comes to fiber network management, operators must be able to visualize how all elements are arranged and related to each other. Creating visual representations of fiber optic networks, or fiber maps, helps bring about a deeper level of understanding of how a network is performing. With fiber maps, operators have a digital record of all network components that is easy to maintain and reference. Evaluating spatial distribution and planning for the future Using GIS platforms, fiber network operators can gain a clearer perspective on how components are distributed spatially across a given market. They can see where they lack coverage and plan expansion efforts more effectively. For example, a network operator could reference a fiber map to see where he or she has excess capacity in existing cable routes. With this information, the operator could make an informed decision on how to expand to serve new clients. Sales teams can also use fiber maps to see where they should focus their efforts. They could query network data to identify potential clients who were positioned close to unused fiber strands. Without investing major capital into new cable installations, sales leads could turn to their fiber maps for ideas on how to grow within a market. GIS fiber maps can also help network managers decide how to allocate limited resources, such as repair support. Guided by GIS tools, they could identify areas with the highest concentrations of clients and place repair technicians near those areas in order to reduce issue response times.

Keeping networks up and running

 Any fiber network operator knows the importance of effective troubleshooting. GIS platforms make it much easier for fiber optic network managers to identify problems and address them quickly. For example, network operators can use the fiber maps to determine where cable issues are occurring. Additionally, field technicians can study urban basemaps to create minimally invasive action plans when cables need repair. At the same time, operators could see where they have extra capacity to support clients while primary routes are repaired. Overall, using GIS for fiber management is less costly and reduces downtime for end users. On a broader level, GIS fiber mapping can help operators discover network vulnerabilities. Fiber maps make it much easier to recognize where there is a lack in network redundancy that could create issues down the road. Operators can use this information to address weaknesses and avoid future problems.

Web-based GIS 

With a web-based GIS product, many different departments within a company can access the data and use it for various applications including engineering, operations, research & development, marketing, finance, and planning. Overall, there are many use cases for fiber maps as operators can combine data layers in countless ways. Being able to visualize network elements has tremendous advantages for managing and optimizing fiber optic networks over the long term. 

Geotagged inventory of customers 

Visualizing customer distribution will generate locational intelligence that will help guide logistics management, enhancing inventory and marketing decisions.

GIS in Everyday Life

Wondering how to identify the accident prone zones on a road? Or how to put up your collected data in a pictorial form on a map canvas? The answer is very simple- GIS, Geographic Information system. Through the use of highly specialized and efficient technology, modern geography is able to collect, analyse, and report on data about Earth’s surface. 

Geographic Information System acts as a powerful decision-making tool for any business or industry since it allows to analyse environmental, statistical and topographic data. Data from GIS applications help companies and various industries, and consumers, make better decisions. Not only for bigger companies and scientific purposes but GIS can also be used by common people to solve their community-level problems. GIS-generated datasheets or maps are easy to read and highly efficient, even for a non-familiar person. For example, GIS can be used to generate accident prone zone map of any selected area or simply to know the crops grown in an area. These maps are easy to read and analyse. 

Let us have a look at some scenarios where GIS can be helpful and convenient. 

1. Urban planning- GIS can help select sites for new developments and analyse the growth in urbanization. It can be useful for construction sites and the laying of new paths. 

2. Environmental Impact Analysis- GIS can be beneficial for the preservation of natural resources and the creation of new eco-sensitive areas. It can also help to understand the impact of human activities on the environment. 

3. Agriculture- More appropriate techniques can be used if GIS analysis has been done over an agricultural area. Production of crops, their maintenance and harvesting can also be managed and known through GIS. 

4. Disaster management- GIS can be a source of information for disaster-prone areas. Being reliable and quick in updates, can help with rescue operations and relocating the people to the nearest safe zones. 

5. Surveying- Data collected through surveys can be easily transferred to GIS software to generate maps and reports that are easier to understand. These can be useful to develop action plans if needed.

 

Apart from the mentioned, GIS is also a tool for navigation, transportation, resource management, garbage management, water facilities and much more. Using GIS for solving the problems that we see around, not only helps to provide a solution but also does it in an effective way. This, in turn, would make things easily manageable and systematic. All we need to do is find the cause of the problem and GIS helps to provide a solution!
