Short name: PALSAR_RTC _hi
ALOS PALSAR radiometric terrain-corrected products will be offered in beam modes FBS, FBD, and PLR.
ALOS PALSAR data is processed to L1.1 using the JAXA processor, then radiometrically terrain-corrected using GAMMA commercial software. Both a high-resolution (12.5 m) and low resolution (30 m) product are available.
The high resolution products will be produced in areas where a DEM of sufficient quality will support such a product:
- North America
RTC High Resolution Product Definition:
- Sigma nought power, floating point, UTM GeoTIFF 12.5 m
- Layover/Shadow mask byte GeoTIFF
- Incidence Angle Map, GeoTIFF, 32 bit float radians
- DEM INT16 GeoTIFF 12.5 m
- Browse geo-JPEG 1000 x 1000 (color for FBD and PLR)
- Metadata ISO 19115 compliant
- KMZ with 30 m overlay
- Beams processed: FBD, FBS, PLR
Complete DEM coverage is required for processing to proceed. GAMMA software handles differences in pixel-as-point vs pixel-as-area, and produces a uniform output.
