Abstract—The study presents a portable spectrometer device for Mapua-Phil-Lidar2 in providing reliable spectral information. This information will complement the unreliable land satellite data that sometimes become obscure and give erratic results to accuracy for resource mapping. Upon using the portable spectrometer device a supplementary data can now be used to complete the resource map and provide an accurate spectral signature of each plant under the study. The proposed portable spectrometer device used a charged coupled device array which converts reflected light into voltage for processing. The developed portable spectrometer consists of Atmega1284P-PU microcontroller, concave holographic grating, charged couple device sensor, global positioning system (GPS) sensor, graphical liquid crystal display (LCD) module and secure digital (SD) memory card. This study highlights the spectral signature taken from the following plants: avocado, banana, cacao, coconut, mango, sugar cane and cottonfruit/santol which cover certain part of the agricultural resources area in the Philippines. A desktop application was also developed to serve as the main interface to transfer the acquired spectral information from the proposed device to a computer for post processing and integration on the Resource Maps.
