This work aimed to apply geoprocessing techniques to identify and to quantify the types of vegetal coverings in part of the county Botucatu – SP, having been divided into three phases: acquisition of data; georeferencing based on the digital topographic maps in 1:50000 scale and finally the thematic maps were generated. The methodology used to the analogical aerial photographics georeferencing showed efficient, considering that it was based on scientific procedures of residues

The methodology used to the analogical aerial photographics georeferencing showed efficient, considering that it was based on scientific procedures of residues analysis and the positioning central was classified as A, according to the Cartographic Precision Pattern.

This study aims to perform the morphometric characterization of the watershed stream Petiço, Botucatu-SP, through techniques of GIS by GIS IDRISI Selva and Charter planialtimetric Botucatu (SF-22-ZB-VI-3) , edited by IBGE (1969), scale 1: 50000 for ranking the drainage network and the morphometric analysis. The variables analyzed were the dimensions, the relief pattern, pattern of the drainage network and the shape variables. The results show that related to how the watershed has an oblong shape with environmental interpretation with low tendency to flooding and erosion. The sinuosity index of 1.22 shows that the channels of the micro tend to be somewhat sinuous, which allows to infer that is permeable soil with good water infiltration. Based on the results of the morphometric variables was found that the watershed is in good condition of conservation, however, presents certain risks of susceptibility to erosion, and environmental degradation in some points, being fundamental to the maintenance of vegetation cover, in view of the roughness coefficient (Rn). Thus, the evaluation of morphometric characteristics in the study watershed constitutes an important tool in conjunction with the use of GIS and Geographic Information Systems makes possible the planning and management of natural resources aimed at their conservation.

The excessive compaction of the soil observed in sod production systems, affects the physical attributes of the soil, which can influence the water infiltration into the soil and hence the rate of soil cover by turfgrasses and time of the sod production. To minimize the effects of soil compacting, some producers use soil preparation equipment that raises the soil on the surface but does not cause excessive roughness which may harm the quality of the sod. Thus, the aim of the present study was to evaluate the infiltration rate and soil cover rate due to different management mechanized in the zoysiagrass sod production. The experimental design had random plots and four replications. The treatments consisted of five mechanized managements of soil: witness (without the use of equipment); coulter blade disc harrow used once (1CB), coulter blade disc harrow used twice (2CB), surface chisel used once (1C), surface chisel and coulter blade disc harrow used once (1C + 1CB). The treatments with 2CB and 1C + 1CB provided greater basic water infiltration speed in the soil and higher rate of soil cover by the turfgrass. The rate of soil cover by turfgrass is positively correlated with water infiltration rate at 133 and 226 DAP, demonstrating the influence of managements used in zoysiagrass sod production and the increment in the infiltration rate of water. Soil preparation utilizing coulter blade disc harrow used twice or surface chisel and coulter blade disc harrow used once is recommended under the conditions this study was done.

The urban area is now home to 50% of world population and the activities related to their disorganized growth, promote the formation of an unhealthy environment. The urban vegetation is necessary and beneficial, because in addition to bringing the man of nature, mitigates climate change and improve the urban microclimate. This study aimed at surveying and analyzing the rate of existing vegetation in urban Piratininga - SP, and from the data obtained, provide allowance for management and planning of green areas and urban areas. Data came from sample survey conducted in 2007 and computerized survey conducted in 2010 indicated that many new neighborhoods have low opt for planting trees of small to medium which does not enhance the urban environment requiring an environmental planning.
