Level 2 Product: (Atmospheric Correction/Data Fusion Product)
Product Description: Radiometric and geometric correction of the imagery, plus atmospheric correction and/or data fusion with other sensors.
Product Details: Level 2 data poducts start with our Standard Level 1 product, and then are fused with data from other sensors. Several types of sensor/data fusion are common:
- Atmospheric Correction: When equipped with the Incident Light Sensor, CASI and SASI data radiance values can be corrected for atmospheric absorption effects to produce true reflectance values. This often provides the basis for further physics-based analysis and derived product generation in the form of our Level 3 products.
- LIDAR or IFSAR: Digital Terrain Model data can be acquired alongside the spectral imagery and fused in processing. The results is a "draped" image mosaic that provides unbeatable geometric accuracy, and can be presented as 3-dimensional models or fly-throughs, incorporated into elevation-sensitive GIS models, as well as providing context-sensitive information for high level analysis.
- Geoid models are also incorporated to reference elevation meaurements to Mean Sea Level (MSL)
