Atualização do mapa de solos do Estado da Paraíba utilizando geotecnologias.

Abstract

Knowledge about the geographical distribution of soils is fundamental for environmental planning. The objective was to update the soil map of the State of Paraíba through the use of geotechnologies. Using the QGIS© 3.28 software and SRTM images, the slope was prepared taking into account where the soil map was adjusted and the nomenclature and legend colors were reclassified, as recommended by the Brazilian Soil Classification System. The slope of the study area was mostly in the Null class of slope in 44.81% of the area. The soil and rock outcrop mapping units underwent changes in areas due to the adjustments, followed by the neighboring areas of the State. The soil areas with the highest occurrence were Neossols, followed by Argissols and Luvissols.
