Before using HyMAP Data, it is quite necessary to be familiar the detail. HyVista Corporation provide data users the with specification of data. It can be downloaded using the supplied link .
According to the specification, all of wavelengths presented in different bands (wave widths) including corresponding FWHM are supplied in Figure 1 and 2 respectively. The information of Bands vs. Wavelengths is extremely useful in practice.
Data Linkage of HyMAP and LiDAR
Ones may feel interested in how data of HyMAP connect those of LiDAR from wavelengths. As indicated before, data of LiDAR is not hyper-spectra. Therefore, only NIR band in LiDAR is able to be linked to the data of HyMAp which have 124 bands. In order for ones to conveniently catch up this concept. The maximum and minimum range of wavelengths in NIR band are listed in a table (see Figure 3) and the meaning of numbers is given in Figure 4. The information of wavelengths shown in Figure 3 could be useful for ones who feel interested in how both data of LiDAR and HyMAP in this band generate some useful information and their potential correlation for the same observed substances.
