Executing aerial photography missions, especially in remote locations, is complex. In order to simplify the process, we use local logistics partners to coordinate flights, locate aircrafts, obtain flight permits, arrange for fuel transit, allow onsite maintenance, ground support, and many other necessary arrangements. We plan ahead in order to enable a smooth operation, and fast delivery. We would like to work with companies that understand the importance of logistics for a successful project, and have the ability to implement it in their home court.

Nadir & Oblique Imagery
Accuracy is Key.
We have an in-house capability of capturing and processing true ortho-photo and oblique images with accuracy as high as a few cms. Our USP lies in our speed of capture which is upwards of 100 sq kms per hour. If you are fed up of using stale and coarse satellite imagery, please get in touch to avail a free demo of digitizing and coding ease on a high resolution base map.
‣ Nadir and Oblique, geo referenced images, up to 5cm GSD
‣ Stereo pairs
‣ Ortho images
‣ OrthoMosaics - up to 5cm GSD
‣ Volume calculation using point cloud analysis.
3D Mapping
We have an in-house capability of capturing and processing 3D data with accuracy up to 5cm using automated photogmetric algorithms and a state of the art 3D mesh engine.
Our aerial image capture solution is the most sought after in the world for its efficiency and ease of use. Experts with over two decades of experience can help solve the most complex images using propitiatory algorithms and softwares.

Technology
Technology is the application of scientific knowledge for practical purposes and one size does not fit all
We at GSL, are focused on using the most efficient technology and tools to help solve complex problems. Our out of the box approach helps us fuse and mate the best solutions from all over the world to cater to the unique needs of each project.
Our efficient technology and flexible operation enable us to offer solutions to many industries that have yet to exploit the benefits of aerial survey and mapping.
Aerial image capture (sweep)
3D Data Acquisition – Large swath on a miniature device.
Innovative dual sweepcamera systems, combined with state of the art photogrammetric tools, enable new aerial mapping capabilities. With various installation options its one of the most effective mapping tools out there.
‣ The sweeping camera system can operate several cameras: PhaseOne IXU-R1000 - 100MP, IXU 150 or Cannon 5DSR - 50MP.
‣ System collects up to 8 images per 3 seconds, moving in perpendicular to the aircraft direction.
‣ Nadir and two sides oblique collection in achieved in one flight pass. A full sweep creates a 300mp large size frame that aggregates 36,000 unique pixels across track (3.6km swath in 10cm GSD).
‣ These individual images are later processed to create large frame image per sweep, flight lines and full mosaic.
Aerial & mobile lidar
Aerial LiDAR (Light Detection and Ranging) is aerial mapping technology that uses calibrated laser returns from the earth’s surface are reflected to an overflying GPS-monitored aircraft equipped with on-board positional and IMU sensors. After post-flight production processes, the acquired LiDAR Map data determines the precise elevation and geospatial location of features on the earth’s surface. With innovations such as multiple intensity returns and increased pulse repetition rates, LiDAR data is an accurate and effective method for creating three-dimensional topographical aerial maps and highly accurate aerial surveys of both surface terrain elements and man-made structures.
We can help create dense and accurate point cloud data sets to help plan and maintain assets. A state of the art mobile lidar system can help gather information on the ground for accessible areas.
multi-sensor gimbal
We have a range of high performance gyro-stabilized single or dual LRU gimbal systems for Surveillance and Utility/Environmental Survey applications. Our electro-optical sensors are augmented with video processing and sophisticated image enhancement allowing users to see through conditions of fog, haze and low-light or darkness. Our inbuilt software can also blend images to exploit features from different sensors providing imagery of activities that otherwise would go undetected.
Network survey vehicle
Our robust multi-functional Network Survey Vehicle System(NSV) is based on the latest survey techniques utilizing Laser, Global Positioning System and Image processing tools. This can be used for automatic collection of road condition related data for Highways safety and Asset Management.
‣ Pavement surface roughness,
‣ Road geometric(s) (gradient, horizontal curvature, and cross slope)
‣ Rut Depth using Spread Lasers,
‣ Sensor Measure Texture Depth,
‣ Mean Profile Depth
‣ GPS Coordinates (X, Y, Z) viz. longitude, latitude & altitude etc.
‣ Roadside inventory and asset management
‣ Contractor quality control
‣ Airport runway maintenance
