HEAT BUDGET-10 YEAR

Entry ID: gov.noaa.ncdc.C00325

[ Update this Record ]

Summary

Abstract: The Heat Budget-10 Year dataset is a subset of the Seasonal Heat Budget dataset. There are four fields per day mapped into a Mercator array and three 9 track 6250 BPI CCT's contain 10 years of non-contiguous data. The 10-year period includes data from June 1974 through March 1978 (which uses the VHRR instrument from NOAA-3, 4 and 5), and January 1979 through February 1986 (uses the AVHRR instrument on TIROS-N series).

Purpose: To make a wide range of climatic data available to researchers and the public.

Quality The sequence of processing steps used were as follows:

Pansharpening
- Fuse or merge the high-resolution panchromatic band with the lower resolution multispectral bands to create a high-resolution multispectral image based on an image transform.
- Panchromatic band has to overlap with multispectral bands in wavelengths.
- Wavelet-based pansharpening is more correct ... from a spectral perspective than ENVIs pansharpening algorithms, such as HSV, Brovey, Gram-Schmidt, PCA, and CN.
- Wavelet Fusion is an ENVI extension available from the ITTVIS codebank http://www.ittvis.com/UserCommunity/CodeLibrary.aspx
- The input images are transformed into wavelet space. Their wavelet coefficients are combined. Then an inverse wavelet transform is applied to the combined wavelet coefficients to create the fused image.
- Fusion strength: the ratios used to blend together the wavelet coefficients of each image at each decomposition level. The settings used:
- Image A: Multispectral image
- Image B: PAN image
- Map projection: Match Image B (PAN)
- Fusion strength: 50:50
- Additional options: defaults
- Output file name: include psdwt (pansharpened with discrete wavelet transform)

Orthorectification

Orthorectification parameters in ENVI:
- Orthorectification was done without GCPs as the match between the DEM and the QuickBird image was very good. Co-registration was applied after orthorectification to fine-tune the image rectification and to match the QuickBird image to the 2004 IKONOS image (metadata ID: "SIC_266_267_georectification").
- RPC model based on the *.rpb file from the panchromatic band - RADARSAT 2002 DEM was first reprojected in ArcGIS, so that it is in a geographical coordinate system.
- The DEM resampling was set to Cubic convolution because it is upsampled to a higher resolution and cubic convolution results in a smoother interpolation.
- The Geoid offset was set to the default of 0.0 as no accurate geoid offset was found on the Geoscience Australia website.
- The projection was set to UTM, Zone 43 South with a WGS-84 Datum.
- The pixel size was set to 0.6 m in both X and Y directions.

Co-registration

Image to image GCPs were selected using a geographic link between the images to aid in feature identification.94 GCPs were identified spread out over the image. The RMS value for a 1st order polynomial was 17.31 pixels (10.4 m). However, as we applied a triangulation (rubber sheeting) transformation, this RMS value has no significant meaning. The QuickBird image was warped using the triangulation transformation method with nearest neighbour image resampling. Output: qb_15dec2006_ps_orc_tri2.bsq
