The Advanced Land Observing Satellite (ALOS) was launched on January 24th, 2006 by the Japan Aerospace Exploration Agency (JAXA) in a Sun-synchronous orbit. It carries three remote sensing instruments: Advanced Visible and Near Infrared Radiometer type-2 (AVNIR-2), Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) and Phased Array type L-band Synthetic Aperture Radar (PALSAR). The PRISM sensor consists of three sets of telescopes for forward, nadir and backward viewing with each telescope providing 2.5 metre spatial resolution. These specifications facilitate generation of precise Digital Surface Models (DSMs) with accuracy sufficient for 1:25 000 scale maps. Geoscience Australia (GA) has been acquiring ALOS data since early 2006 and holds an extensive archive of PRISM images over Australia and New Zealand that are suitable for DSMs generation

Movie created for Remote Sensing Science and Strategy. This short movie contains Hay point MODIS images and Landsat images shown simultaneously on screen. There are 97 MODIS images (each 912kb in size). There are 27 landsat images (each 1mb+ in size).

Normalising for atmospheric and land surface bidirectional reflectance distribution function (BRDF) effects is important in satellite data processing. It is particularly important for standardising time series data and for inter-sensor calibration and comparison. Procedures based on physical models have been applied successfully with the Moderate Resolution Imaging Spectroradiometer (MODIS) data products at global scales. For Landsat and other higher resolution data, similar options exist except that the estimation of BRDF using internal fitting, as used for MODIS, is not available due to the smaller variation of view and solar angles, sun-synchronous view and infrequent revisits. Despite this, the use of physical models for atmospheric correction and BRDF normalising can still be appropriate. In this study, we explore the potential for developing operational procedures to correct higher resolution sensor data based on combined atmospheric and BRDF models. The process was realised using BRDF parameters (shape functions) derived from MODIS and using the MODTRAN 4 radiative transfer model. The approach was tested using Landsat data for two sites with different land covers in Australia. The retrieved Landsat reflectance values have good agreement with ground based spectroradiometer measurements with the root mean square difference (RMSD) for both sites being less than 3%. The comparison between normalised Landsat and MODIS reflectance shows a strong relationship, indicating that cross-calibration between the two sensors is achievable. Strategies which may provide effective BRDF parameters before MODIS was available (and after its mission is complete) are also discussed as well as the options that exist for an operational system in the context of monitoring land cover change.

The AC/P8 airborne laser fluorosensor (ALF) survey is located in the Northern Bonaparte Basin. The survey was flown in three flights between 29th November 1996 and 1st December 1996. Fifty lines were acquired at 500 m spacing in a NW-SE direction. Line lengths ranged from about 26 km to 32 km with a total of 1,490 km acquired. A total of 1,040,856 spectra were collected at an average spacing of 1.34 m to 1.49 m. Of these 249 were selected as confident fluorescence spectra in the second pass interpretation. The majority of fluors were small but there were also a significant number having medium intensity. Fluor clusters were notably absent from the Corallina Field and only a few fluors were located over the Laminaria Field. The relatively high density of fluors ranging up to medium size over the survey may indicate a working source and migration system.

The AC/P16 airborne laser fluorosensor (ALF) survey is located in the Northern Bonaparte Basin, Timor Sea. The survey was flown in one sortie on the 2nd December 1996. Sixteen lines were acquired at 700 m spacing in an E-W direction at a flying height of 100m. Line length ranged from 23 km to 30 km, with a total of 412.9 km acquired. Line 20070 was a repeat of line 10070. A total of 290,337 spectra were collected at a spacing of about 1.42m. Of these, 111 were interpreted as showing confident oil fluorescence spectra. Fluors were mostly of small to medium intensity with none having F/R area ratio larger than 0.75. Most of the fluors were located in the eastern half of the survey in two main clusters. No fluorescence curve trends were noted but the survey area may be too small to show significant trends.

The Vulcan Graben airborne laser fluorosensor (ALF) survey is located in the Vulcan Sub-basin, Timor Sea. The survey was flown on December 2nd 1996. 149 lines were acquired at 300 m spacing in a NW-SE orientation. A total of 1,569,074 spectra were collected at an average spacing of 1.45 m to 1.65 m.Of the 183 fluors picked during the refined interpretation, 70 were large fluors with a F/R ratio larger then 0.3. Some of the fluor clusters may be related to leakage from the Skua Field and Spruce Prospect although direct correlation between fluor clusters and accumulations are not reliable. The fluorescence peak wavelength tends to move to longer values moving from the NE to the SW.

The 1996 Yampi Shelf airborne laser fluorosensor (ALF) survey was flown in two sorties on the 1st December 1996. Twenty three lines were acquired at 1km spacing in a N-S direction at a flying height of 100 m. Line lengths ranged from 20 km to 23.6 km, with a total of 488.7 km acquired. Of the 343,563 spectra recorded, 57 were interpreted as having confident fluors (165 fluors per million spectra). These were mostly low intensity fluors with only one having a F/R ratio above 0.30. The fluors were found mostly in the eastern half of the survey in broad clusters.

The Haydn airborne laser fluorosensor (ALF) survey is located in the Vulcan Sub-basin, Timor Sea. The survey was flown in two sorties on the 2nd December 1996. Sixty-five lines were acquired at 400 m spacing in a NW-SE orientation with a total of about 550 square kilometres acquired. Seventeen lines were acquired at 1200 m spacing in the orthogonal NE-SW direction. The NW-SE lines were about 21.35 km long while the NE-SW lines were about 26 km long. Many types of noise were found on the ALF records and these were rejected during the manual checking phase of fluor selection.Of the 1,529,484 spectra recorded, only 21 were interpreted as having confident fluors. No significant fluorescence clusters were observed. Only 4 fluors were found with a F/R ratio above 0.30.
