Umburana (Commiphora leptophloeos (Mart.) J. B. Gillett) is a species that has wood, forage, ornamental, meliferous and medicinal value. The objective was to identify the spectral pattern of umburana (Commiphora leptophloeos (Mart.) JB Gillett) through geotechnologies. The evaluation of changes in patterns was used theNormalized Difference Vegetation Index (NDVI) and the Moisture Stress Index -MSI in apreserved vegetationareaatMunicipality of Senador Rui Palmeira, state of Alagoas, Brazil. The research was carried out on aproperty located at Sítio Queimada Grande, rural countryof Senador Rui Palmeira, AL. The area was mapped using images. The entire area was covered, with theidentification of the Umburanas-de-Cambão found and with the use of GPS, their georeferencing. Thedetermination of NDVI and MSI was obtained through Google Earth Engine, images from the Sentinel 2 Satellite. In the pedological coverage, 88.25% of the umburanas occurred inLuvissolos Crômicos Órticos Vertissolicos. As for NDVI, the average values found during the year of the study ranged from 3 to 7. As for NDVI, the average values found during the year of the study ranged from 3 to 7. Of the 127 umburanas identified, 117 are in the preservation area and only 10 occur outside it. NDVI was variable, reaching peaks in the months of greatest amount of rain, between June and July. As for the MSI averages, there was variation 2 and just over 12 throughout the year, with peaks at 100 days and between 150 and 220 days. The NDVI and SMI presented higher valuesin the month of February with indexes of 0.3 and 4.5, respectively. Based on the observed correlation between NDVI and temperature, the main mechanism that controls the photosynthetic activity of umburanas is temperature.
