In order to fill the domestic blank in automatic retrieval of water Chlorophyll-a concentration using push broom images, an automatic retrieval system of Chlorophyll-a concentration based on push broom images was designed and implemented on ENVI redevelopment platform in this paper. An airborne push broom hyper-spectrometer called Pika L with high spectral and spatial resolutions provides hardware support for retrieving more accurate and real-time Chlorophyll-a concentration. According to the characteristics of Pika L images, the automatic retrieval system mainly includes geometric correction and mosaicking, radiometric calibration, atmospheric correction and Chlorophyll-a concentration retrieval. The results show that the automatic processing of Pika L push broom images based on the ENVI redevelopment is a feasible technical solution and it provides technical support for automatic and real-time retrieval of water Chlorophyll-a concentration.
