Neusling (Landau a.d. Isar) 2011 - An Agricultural EnMAP Preparatory Flight Campaign Using the APEX Instrument (Datasets)

This data collection contains airborne hyperspectral data as well as accompanying in-situ data acquired in autumn 2011 in the Neusling test area near Landau a.d. Isar in Southern Germany. The dataset is composed of a) three airborne hyperspectral image strips acquired during an overflight on September 10th, 2011 with the APEX instrument. The airborne data consists of 288 spectral bands, ranging from VIS to SWIR (413 - 2449 nm). A mosaic of the three image strips covering the Neusling test area is also provided; b) spectral reference and control measurements acquired with a portable ASD FieldSpec 3 JR spectroradiometer in 2150 spectral bands (350 - 2500nm) taken parallel to the overflight; c) a spatially comprehensive land use/land cover map generated from in-situ observations during the days next to the overflight; d) Flight-parallel in-situ point-measurements consisting of: i) non-destructively measured leaf area index of sugar beet, maize, grassland and legumes (105 measurements incl. standard deviations), ii) SPAD chlorophyll measurements (106 measurements incl. standard deviations), iii) 106 measurements of canopy height (incl. standard deviations). The dataset was collected with an agricultural focus.

本数据集包含2011年秋季在德国南部伊萨尔河畔兰道附近的诺伊斯林（Neusling）试验区采集的机载高光谱数据及配套现场数据。该数据集由以下部分组成：a) 2011年9月10日使用APEX仪器在一次航飞中采集的三条机载高光谱图像条带。机载数据包含288个光谱波段，范围从可见光（VIS）到短波红外（SWIR）（413–2449 nm）。还提供了覆盖诺伊斯林试验区的三条图像条带的镶嵌图；b) 与航飞同步采集的、使用便携式ASD FieldSpec 3 JR光谱辐射计获得的2150个光谱波段（350–2500 nm）的光谱参考及控制测量数据；c) 基于航飞前后几天现场观测生成的空间综合土地利用/土地覆盖图；d) 与航飞同步的现场点测量数据，包括：i) 甜菜、玉米、草地和豆类作物的无损叶面积指数测量（105次测量，含标准差）；ii) SPAD叶绿素测量（106次测量，含标准差）；iii) 冠层高度测量（106次测量，含标准差）。本数据集的采集以农业应用为重点。
