Survey technology developer Maptek is demonstrating the workflow of I-Site Studio software for processing and modelling airborne data at this week’s International Lidar Mapping Forum in Denver, Colorado, USA. Datasets captured by UAVs and other aerial methods are large and often cumbersome to work with. Tools in I-Site Studio readily convert this point cloud data into practical digital deliverables.
I-Site workflows streamline the path from dense Lidar data to useful output, said I-Site Engineer Clayton Fritz from Maptek. Intelligent filtering options are the first step in making the file size manageable. Minimum point separation filters extraneous points without sacrificing detail. Users can also choose to keep the lowest points and screen out vegetation so an accurate, unobstructed topographic surface is the result. Accuracy is not lost for modelling surfaces and calculating volumes.
If point data is the required deliverable, then there’s nothing simpler than bringing the data into I-Site Studio, filtering to a size that can be managed by other programs and exporting the point cloud dataset, Fritz further explained.
I-Site Studio allows surfaces to be exported as multiple different file types. Contours and sections can be generated with one click. Interactive CAD tools mean that geometry can be drawn directly onto data. Users can swap between views during editing. Breaklines (also called toe and crest strings) are automatically generated for easy definition of mining faces and input to mine planning.
As aerial devices become more affordable for mapping extensive operations, users need multi-layered software to manage their data, Fritz concluded.
