|metadata.revistascielo.dc.description:||This study identified, quantified and analyzed changes in land use and cover on the campus of Federal Universityof Lavras campus, located in Lavras city (Minas Gerais State). The 2009 QuickBird satellite imagery and 1985, 1979, 1971, 1964 vertical aerial photographs were used to produce a set of land use and land cover maps. The work started with the orthorectification of the QuickBird satellite imagery and vertical aerial photographs. The identification and definition of land cover and land use classes were obtained from field surveys in 2009. First, the land cover and land use maps were made from that information. Finally, the quantification and analysis of changes were performed at the imagery time range. The results showed that in 2009 the “urbanized area class” of the campus reached 65.79 ha and that the most significant increase of this class occurred between the years 1964 (6.24 ha) and 1971 (24.4 ha). The smallest area of “forest land class” found on the campus was 38.38 ha in 1971, and from 1979 on this situation has been improved reaching 113.18 ha of “forest land class” in 2009. For the “water class” there was not any dam constructed yet in the campus before 1971. Most of the campus area, previously used for “agricultural land class” had a significant reduction within this category, from 384.19 ha in 1964 to 271.16 ha in 2009.|
