Dear all, I have a field spectrometer data for urban features, I had finished established the spectral library for the each feature and mean all the spectral. However the data still not have the right projection yet. Referring to this problem, how I will set the projection to that data and how I will use that data in establishing the training area? I had tried to set by using edit envi header but its not working. Field spectrometer data in vector format, do I need rasterizing the data first?
