What is Verified View Survey Data?

Posted on by OgilvieGeomatics

A verified view, also known as an accurate visual representation, is a photo-montage with detailed data on the exact location of the camera and key points within the photography. Verified view survey data plays a vital role in a variety of projects, from environmental impact assessments (EIAs) to planning applications.

Ogilvie Geomatics has a wealth of experience providing survey data for verified views in central London and throughout the UK. When verified view data is requested, Ogilvie Geomatics’ expert surveyors visit the site and record a broad range of reference points, and the location of the camera itself. Using high-precision vision instruments with in-built cameras, it is possible to provide detailed and highly accurate survey data for verified views.

Reference points on buildings, structures and roads can be acquired in the correct co-ordinate system by using precise GPS observations. Clients are provided with exact camera positions and horizon points which are meticulously linked to the OS grid by static GPS observations. 

Data is provided in the form of a report, in whatever format is required. Clients are provided with individual images of each position taken using a camera within Ogilvie Geomatics’ total station, as well as marked-up imagery of the points and 3D CAD files displaying the precise location of the plan’s points.

 

What are Underground Service Tracing and Utility Surveys?

Posted on by OgilvieGeomatics

As the pressure on the UK’s infrastructure continues to grow, the need for accurate, up-to-date information on the location of underground utilities is greater than ever. Ogilvie Geomatics are industry leaders when it comes to providing detailed underground surveys, paving the way for utilities to be replaced, maintained and improved.

Ogilvie Geomatics offers underground utility location and mapping services throughout the UK and around the world. Our team of highly experienced surveyors utilise state-of-the-art underground pipe location and cable detection devices to provide a comprehensive underground utility location and mapping service.

Ogilvie Geomatics’ surveys comply with the guidelines of PAS128, which aims to provide clear provision for surveyors of utilities, whether they are active, abandoned, redundant or unknown.

Ogilvie Geomatics Utility Mapping Solutions has invested in cutting-edge, dual-frequency ground-penetrating radar (GPR), GPS equipment and radio detection, making it possible to map a broad range of underground utilities, keeping risks to a minimum before digging begins. A variety of techniques are used to ensure that our underground surveys & utility surveys are completed with the utmost efficiency.

Clients are provided with in depth, up-to-the-minute data on underground services, including communications (such as BT and Virgin), electricity, gas and water. Investigations are meticulously planned, according to the specific characteristics of each site. Ogilvie Geomatics’ surveys generally investigate to a depth of 2 metres. 

Our team of surveyors use radiodetection cable and metal pipe locators to locate buried metal cables and pipes. A generator-induced signal is traced along utilities to record accurate and up-to-date information on their location. A dual-frequency signal transmitter called a Sonde is also often used to record data on the location of sewers, drains and other non-metallic, non-conducive services.

Ground-penetrating radar (GPR) is a geophysical surveying technique which creates a cross-sectional profile of underground features, without having to dig, drill or disturb a site in any other way. Surveyors transmit ultra high-frequency radio waves – known as microwave electromagnetic energy – into the ground through a transducer, or antenna. Transmitted energy is then reflected by buried underground objects. Reflected waves are received by the transducer and stored in a digital control unit. GPR profiles have a vital role to play in assessing the depth and location of buried features. They also make an important contribution to investigating the presence of natural underground features.  

 

What is an Unmanned Aerial Vehicle and how is it used in surveying?

What is an Unmanned Aerial Vehicle and how is it used in surveying?

An unmanned aerial vehicle (UAV), also known as a drone, is an aircraft which is controlled remotely, rather than by an onboard pilot.

There are two main types of UAV: fixed-wing and multi-rotor. While fixed-wing UAVs can generally fly for up to one hour and are suitable for surveying up to 2,000 hectares, multi-rotor UAVs are limited to shorter flights but have the advantage of being able to take off vertically and hover to capture oblique or panoramic images.

In recent years, UAVs have transformed surveying by making it possible to safely complete surveys of inaccessible or hazardous land, and save considerable time and money by collecting a large amount of data during one short flight.

Thanks to recent advances in technology, UAVs are now capable of producing high-resolution aerial photography and recording highly accurate topographic survey information.

The information acquired by UAVs is used for assessing potential site locations, designing site layouts, assessing site visibility and monitoring construction progress.

With its partner Cyberhawk Innovations, Ogilvie Geomatics use state-of-the-art UAVs to create geo-referenced aerial images which are related to OS National Grid with a ground resolution of at least 3cm per pixel.

UAVs enable the team to provide orthophotos, digital elevation, precise topographic data and aerial panoramic images. From as high as 120 metres above ground, photos can be takes to show a 360o view of the site below.

UAVs are a valuable asset in a variety of projects, including topographic surveys, route surveys, construction progress imagery, as-built surveys, volumetric analysis and environmental impact assessments. 

There are numerous advantages to UAVs, which enable surveyors to complete projects safely and cost-effectively. 100 hectares can be surveyed in a single day, and potentially dangerous areas can be studied with very little ground access.

 

Ogilvie Geomatics also use UAVs to carry out meticulous visual inspections of structures which are tall, live or difficult to access, including bridges, wind turbines, transmission towers, dams and chimneys. UAVs are even capable of inspecting the tips of wind turbines’ blades, which were previously extremely difficult to reach.

UAVs are equipped with cutting-edge technology such as LiDAR, a terrain-mapping technique whereby lasers are used to measure the distance from the ground to an airborne sensor, creating detailed terrain maps which can be used for property development, flood risk assessment and a range of other projects.

     

What is a Measured Building Survey?

Posted on by OgilvieGeomatics

A measured building survey is accurate record of a property, its structural features as they are when the survey is undertaken. A measured building survey is a result of direct measurements on site that is normally delivered in 2D and 3D digital formats. The measured surveys have an important role in the establishment, maintenance and building information systems. 

Floor plans, building elevations, building sections, roof plans and reflecting ceiling plans can be produced with AutoCAD, REVIT or other similar software and the formats are DWG and PDF.  

A measured building survey is normally very detailed, depending on client’s requirements, it could be on a scale of 1 to 50 or 1 to 100. Sometimes clients could ask for even bigger scale such as 1 to 20 and of course the level of details on a floor plan or a section is much higher. 

For more than 25 years, Ogilvie Geomatics have been completing measured building surveys around the world, to the very highest standards.

The team uses state-of-the-art technology to provide its loyal client-base with a range of services, including space management, area calculation, photogrammetry, rectified photography and Scan2BIM.

In order to carry out measured building surveys with the highest degree of accuracy, Ogilvie Geomatics’ team of land surveyors utilise new technologies such as reflectorless total stations, which are connected to tablet PCS for real-time data analysis.

To enable immediate access to raw data, laser scanners generate point cloud information in various formats, including TruView.
