Titled: EO spectrometer helps to identify relevant bands for early detection of famine weed.

A recently purchased Spectral Evolution field spectrometer by Earth Observation directorate was put to task in a quest to identify relevant spectral bands for early detection of a harmful invasive alien plant commonly known as famine weed.

This instrument was used in the field to capture reflectance from famine weed and other different plant types occurring in the same area. To the naked eye (or visible region of the electromagnetic spectrum), these plant species look similar due to their green coloured leaves and can only be differentiated based on their structure at a closer look. But such exercise would be time consuming, costly and tedious. On the other hand, field spectrometer allow for identification of different plant types based on their unique absorption and reflection intensities in different parts (or bands) of the electromagnetic spectrum.
