The aim of this work was to elaborate a cartographic basis for storage and spatial analysis of data on diversity of palm trees in altitudinal gradient. The work was carried out in Serra do Mar, located on the northeast of Sao Paulo. In order to create a databases an altimetric letter from IBGE 1:50.000 and a Landsat ETM+ image from 2002 in bands 3,4 and 5 have been used. Data have been analyzed in the SPRING System of Geographic Information 3.6 version, developed by the National Institute for Space Research (INPE), Brazil. The sequence of elaboration consisted of register, digitalization of level curves, and creation of a rectangular, triangular and data table. From this sequence declivity and hypsometric thematic maps have been obtained. Later on the association of the number of species by altitudinal class giving origin to a map of palm tree species distribution in an altitudinal gradient was carried out. The databases are available for association to other parameters with climate, soil, distribution, and abundance of palm tree species for more elaborated spatial analysis.
