2013 Simulated EnMAP Mosaics for the San Francisco Bay Area, USA

This dataset is composed of simulated EnMAP mosaics for the San Francisco Bay Area, USA. Hyperspectral imagery used for the EnMAP simulation was collected across three time periods (Spring, Summer, and Fall) in 2013 with the AVIRIS-Classic sensor flown as part of the HyspIRI Preparatory Campaign. Flight lines were simulated to EnMAP-like data using the EnMAP end-to end Simulation tool to produce 30 x 30 m imagery with 195 bands (after band removal) ranging from 423 to 2439 nm. Secondary geometric correction was applied using automatically generated tie points, and a class-wise empirical across track brightness correction was implemented to mitigate brightness gradients.

该数据集由美国旧金山湾区的模拟EnMAP镶嵌图组成。用于EnMAP模拟的高光谱图像采集于2013年的三个时间段（春季、夏季和秋季），由AVIRIS-Classic传感器获取——该传感器飞行任务是HyspIRI预备活动的一部分。使用EnMAP端到端模拟工具将飞行航线模拟为类EnMAP数据，生成30×30米分辨率的图像，包含195个波段（经波段移除后），波长范围为423至2439纳米。利用自动生成的连接点进行二次几何校正，并实施了逐类经验性跨轨道亮度校正，以减轻亮度梯度。
