LiDAR, Drone & Engineering Topographic Surveying

Geospatial, Engineering Surveying & Mapping

We are countrywide leader for LiDAR and Engineering Surveying. We are using latest technologies include Mobile LiDAR, UAV (Drone) LiDAR, RTK/PPK quipped drone photogrammetry, DGPS, Electronic Total Station and Auto Level. Other Services include Point Cloud Data Processing and Drone Image Data Processing projects.

Goodland Surveys Private Limited established in 2003, completed many projects throughout India & few abroad projects (Maldives, Gabon(Africa), Italy, Egypt & Brisbane-Australia) and also, we awaiting some more in near future. We have structured ourselves in such a way that we meet the requirements of the modern surveying practice. With the above in the background and the wholehearted support from our valued customers, we are able to successfully march one step forward towards our goal.

LiDAR Survey

Mobile LiDAR is collecting Topographic and Geospatial Data from a Vehicle, i.e., Car, Train, Boat or any other mobile vehicle. The Primary output from the Mobile LiDAR is High Dense Point Cloud Data, Geo Referenced Images and Video. CAD or GIS Compatible drawings shall be prepared from the Point cloud. DEM, DSM and Contour maps shall be prepared after the post processing of LiDAR Data. The system is very suitable for Highway and Railway Corridor mapping that helps Designing, Construction and Asset Mapping projects. GPS and Inertial Navigation Systems have allowed accurate and dense measurement
Know More..

UAV based aerial LiDAR is very effectively collecting data for Urban power line management, Power line corridor management (Transmission line & Pylons) Stock volume calculation, open mines, green field corridors, and etc. It provides high-accuracy / high density point cloud for survey grade mapping.

Aerial mapping has become more efficient and affordable than ever. For increasing mapping accuracy, which shall be achieved by higher-grade INS, more sophisticated post-processing algorithms (e.g. SLAM), and other solutions provided by developers. UAV LiDAR can be used for surveying of Highway and Railways, Forest Management, Mining, Oil & Gas Pipelines, Utility Management

UAV Photogrammetry Survey

For Drone Survey, we are using RTK/PPK UAV for collecting images. The Phantom 4 RTK produces high-resolution drone maps and 3D measurements that are accurate to within a few centimeters, without using ground control points (GCPs).

In order to perform the PPK Corrections, we observe a base GPS (in a Static Control Network). The rover observation file is saved directly onto the Phantom 4 RTK’s SD memory card. The file comes in RINEX version 3.03 and is the raw satellite observation data. Rover Trajectory shall be processed with reference to the base station and the accurate positions exported to each & every image of the mission.

Improved Accuracy - Accuracy across the entire map should be less than 10cm RMSE, often 2cm RMSE when evaluated with checkpoints. Read more...

Engineering Surveying (Total Station & DGPS)

Engineering surveys means all survey activities required to support the planning, design, construction, maintenance, and operation of engineered projects, which include locating or laying out alignments, positions, or elevations for the construction of fixed works

The main surveying instruments are the DGPS, Electronic Total Station, 3D scanners, Auto level, etc. Most instruments fitted onto a tripod when in use. Read More...
