Geospatial data

Since 2003 we have been working in the field of geodesy and cadastre. We have all the necessary licenses to perform this activity.

Solutions using Unmanned Aerial Systems (UAVs) allow the rapid collection of accurate geographic data Photogrammetric processing software compiles. This data provides standardized results.

With our UAV, F&F Consult strives to provide clear research / mapping services throughout Bulgaria. From servicing the government and private sector in geodesy, aerial photography for land management and development, land surface surveillance, volumetric measurements of natural resources, urban planning, mapping of green systems projects, etc. Our experience remains unsurpassed.

UAV images are corrected for image distortion and stitched together during post-processing to create a highly-accurate orthomosaic map. Each pixel contains 2D geo-information (X, Y) and can directly procure accurate measurements, such as horizontal distances and surfaces.


A densified point cloud can be generated from UAV images. Each point contains geospatial (X, Y, Z) and color information. It provides a very accurate model for distance (slant and horizontal), area and volume measurements.


UAV images can also be used to create DSM models of the area. Each pixel contains 2D information (X, Y) and the altitude (Z value) of the highest point for this position.


After filtering objects such as buildings, the drone images can be used to create DTMs with each pixel containing 2.5D information (X, Y, and Z value of the highest altitude).


Depending on the project requirements, either the DTM or DSM model, with custom contour intervals, can be used to create a contour lines map, giving you a better understanding of the surface of the area shot by the drone.


The 3D textured mesh is a reproduction of the edges, faces, vertices and texture of the area shot by the drone. This model is most useful for visual inspection or for when external stakeholders, or public involvement is essential for a project.

We can help with


Our nationwide and tailored service of drone surveying enables us to procure precise topographic maps and 3D. Extensive land surveys and topographical surveys permit the most definite representation of cadastral maps, immediately and in a hassle-free manner. Our GIS crew post-processes the data with photogrammetry software to generate deliverables like a detailed Digital Elevation Model (DEM), Digital Terrain Model (DTM), contours, brake lines, ortho-mosaic/ortho-imagery, interactive 3D Mode, and 3D reconstructions of land sites or buildings.


We encourage organizations to adopt topographic surveys for a more thoughtful land planning and management process. Providing well-defined and more expeditious data, our background in land management and development has supported several private and government agencies for secure pre-construction planning. We steer our attention to site scouting, allotment, planning, design and the concluding construction of roads, buildings and utilities. Accurate aerial surveying / mapping and topographical mapping at frequent intervals of time retain the course of construction and plans, at pocket-friendly costs.


UAV are a popular and conventional method of Stockpile measurements in the industry. Our pilots can conduct Stockpile analysis with our highly exquisite surveying drones and capture extensive topographic data points, that traditional methods can not detect due to their irregular shapes. Surveying can capture and depict all these variations as shape's actual volume and not just its estimate. We strategically and efficiently deliver photogrammetric information through Contouring, Digital Surface Models, stockpiles such as waste, mines, inventory and agriculture. Volume measurements with a nearly 99% accuracy rate.


Slope failure is a geologic hazard and is imperative to be detected early on to retain safety. The slope monitoring process through GIS mapping conducted by our experts successfully recognizes the steepness of the ground's surface using the Digital Terrain Model (DTM) and Digital Surface Model (DSM). This information, along with the LIDAR survey data, is essential for slope monitoring, landslide mitigation and prevention of slope failure. Aerial survey mapping is an added valuable tool used by specialists to track the Earth's movement to help predict and prevent such destruction.


With astonishing advancements in UAV technology, the use of drones in urban planning has become extensive. Through drone surveying, we can accumulate enormous amounts of data quickly and at lower prices due to AI processing and machine learning. We have passionately remitted our expertise to numerous private builders and government agencies to plan and examine the sites' existing social and environmental conditions. A treasured part of our success stems from capturing high-resolution aerial data, LIDAR surveys and other significant information using cutting edge drone technology.
