Terrain measurements using total station and GNSS instruments are usually combined with LiDAR data to produce information rich survey plans (scales of1 : 1000 and smaller) of 3D vector models.
Various specific maps can be produced using LiDAR derived elevation data in combination with other imagery. Multitude of information can be gathered and presented down to a single tree. The following products can be produced:
- Canopy height models (CHM)
- Single tree detection
- Forest change detection
- Species classification
- Forest damge estimation
- Biomas, volume & density calculations
Many agriculture related remote sensing techniques have been developed during recent years i.e. detection of cultivated fields, monitoring crop growth & crop damage assessments. Performing automatic and semi-automatic classifications we can calculate surface areas, field borders and detect annual changes.
Similar to above methodology a host of other thematic maps can be produced used in environmental management:
- Land cover use mapping
- Disaster prediction, assessment and monitoring
- Species habitat simulations
- Material deposits locations
