We specialise in providing topographical site surveys, terrestrial laser scanning and airborne surveys. We have many years of experience with pipeline mapping and have developed a means of mapping pipelines from the surface without an IMU.
"Precision" - The quality, condition, or fact of being exact and accurate.
We can provide very high quality aerial imagery, down to 5cm per pixel resolution. Often, we combine high resolution aerial images with LiDAR data to create a rich 3D data set by 'draping' the imagery over the high resolution Digital Terrain Model.
LiDAR can aid in the evaluation of prospective sites, a LiDAR survey can include aerial photography and provide digital elevation models, contours, slope and aspect maps that can be incorporated into a GIS package,
LiDAR has the advantage of 'seeing through the foliage' to map the ground, even in rainforest. A LiDAR survey can aid in pre-planning, identify staging areas, position construction crews to work in downhill directions, logistic planning and safety planning.
The image (left) shows a project in Algeria, where we assisted a client with a LiDAR survey for a seismic project. We delivered seismic line profiles that were used to determine elevation changes and slope.
We can provide or source lidar surveys for you based on an independent appraisal of your requirements. We also provide independent quality control, confirming the accuracy of LiDAR data you may purchase from other providers. We can write the specifications for the laser scanning survey work and ensure they are adhered to.
If you provide laser scanning services, we can provide independent confirmation of your accuracies and offer ground GPS control services - worldwide. LiDAR processing services include coordinate transformation services for both plan and height data. Also, we can process the LiDAR data to produce a variety of digital products, including: Digital Elevation Models, contour models, vector maps for showing water drainage &more.
