One of the challenges in the development of a hyperspectral satellite is the extremely high data rate due to the huge data volume generated on board, which exceeds the downlink capacity, and may quickly exhaust the onboard storage capacity. To deal with this challenge the Canadian Space Agency (CSA) has been developing data compression technologies for satellite imagery data for many years. Compression techniques for operational use have been developed. Recently, two near lossless data compression techniques for hyperspectral imagery have been developed and implemented in hardware. The CSA is considering a near lossless data compressor for use on-board a hyperspectral satellite in order to reduce the requirement for on-board storage and to better match the available downlink capacity. This invited paper is to review the research and development of satellite data compression for hyperspectral imager at CSA, briefly summarize the two near lossless compression techniques, to address the application based assessment of the impact of lossy or near lossless data compression on Earth observation applications, and to provide up-to-date status of the hardware implementation of the on-board data compression technologies.

“…In order to move towards a national monitoring capability with hyperspectral data, the Canadian Space Agency (CSA) [1] led a phase-A study for the Hyperspectral Environment and Resource Observer (HERO) satellite. The HERO sensor characteristics were spectrally from 400 nm to 2450 nm with 10 nm bandwidth per channel, and spatially 30 m pixels with a swath width greater than 30 km.…”

Canada contains 10% of the world's forests, covering an area of 418 million ha. Remote sensing can provide rapid coverage of these forests. Forest information needs are moving from broad forest typing to mapping of major forest species. Hyperspectral sensing can be used to create products for forest inventory, forest health, biomass, and aboveground carbon.The challenge is to develop a process to extract from hyperspectral data the relevant forest information in a timely and reproducible manner with a high degree of confidence in the quality of the resultant products. To answer this challenge, experiments have been conducted on two test sites: the Greater Victoria Watershed District (GVWD) on Vancouver Island, BC, and the Hoquiam test site in Washington State. Three types of data were collected to perform the analysis. First, Hyperion and AVIRIS hyperspectral images were collected for both test sites. Secondly, ground truth reflectance data were acquired from locations within the GVWD test sites simultaneously with these image collections. Finally, foliar samples were taken and chemically analyzed from 30 Douglas fir plots in the GVWD test site and five plots in the Hoquiam test site to provide a sample set of known values to compare against the spectral imagery. This paper reports on the results for chlorophyll and nitrogen mapping for these sites. Difficulties associated with chemistry signature extension are discussed. For nitrogen, an r 2 of 0.915 was obtained between ground measured nitrogen and nitrogen predicted from AVIRIS data.
