Aplicação de um método ergonômico para avaliação da permanência e atratividade em espaço público aberto: estudo de caso Parque Vitória Régia, Bauru - SP

There are several researches on evaluation of urban public space, but not all establish a relationship between the configuration of spaces with the thermal environment, ergonomics and environmental behavior of users. To understand this relationship, the aim of this paper is to present the model DEPAN (Design for Permanence and Attractiveness in niches open spaces of conviviality), based on graphical meshes, which were designed to evaluate the influence of design and ergonomics of open public spaces in the human thermal comfort and the ways in which users appropriate the space. Its applicability is demonstrated through a case study conducted in a park in the city of Bauru-SP. To perform this evaluation public space niches were chosen. They were formed by morphological elements and street furniture and defined by their spatial arrangements. The collected data were incorporated into a Geographic Information System (GIS), which allowed the overlay of meshes. The results indicate that the DEPAN model allows the verification of the spatial characteristics, thermal quality and ergonomic design generated by spaces, as well as the evaluation of the influence of these aspects in the way of using the spaces. The model allows the generation of a classification for every niche and set a value for the level of service offered.

Imagens digitais na análise do uso da terra de uma microbacia como subsídio ao desenvolvimento sustentável

The present work sought to discriminate, to map and to quantify the areas of soil use of the Stream Monte Belo watershed - Botucatu (SP), obtained by digitale images. The cartographic bases were the shart planialtimetric, edited by IBGE (1969) and the satellite images LANDSAT - 7, passages of 21/01/1999, 08/01/2003 and 23/10/2006. The Software Idrisi Andes 15.0 were used for conversion of the analogical information for digital and for determination of the vegetable coverings areas. The results allowed to verify that the SIG - IDRISI Andes 15.0 were efficient in the quantification of the areas with soil use and that the analysis of the data showed a cash progress of the areas of reforestations to the detriment of the areas of pastures, especially from 1999, 2003 to 2006, when the field areas were substituted by the forestry in his totality. In spite of that progress, the forest areas that you correspond to the Permanent Preservation Areas, They are considerably preserved. That result comes to the encounter of the tendency of expansion of the forestry, especially after the installation of cellulose industries in the area, what worsened the environmental problems originating from of the practice of the monoculture.

Medições de áreas por fotografias aéreas, em escala nominal, comparadas com a área obtida em fotografias com escalas corrigidas por meio de um SIG

Land use management has becoming a very important activity. Aerial photo interpretation is a basic resource and constitutes in a technique which enables infinite refining. Agricultural development and land use require a careful initial planning in order not only to protect them against superficial changing provoked by natural phenomenon but also to gradually develop its productive capacity. For the efficiency of land management, it is necessary to access correct and detailed information which can be available through aerial images of remote sensing. The use of vertical aerial photography through Remote Sensing has become more common in boundary survey projects, management and exploration, mainly because it substitutes, with lots of advantage, for cartographic bases, besides offering detailed characteristics, eliminating access difficulties in inaccessible areas, as well as facilitating a tridimensional view once it increases map efficiency and accuracy by combining field and laboratory work with photography interpretation. This work, using panchromatic aerial photography in nominal scale 1:25000 (1962), 1:45000 (1977) , and approximate nominal scale of 1:30.000, originating from aerial survey obtained in 2005, aimed at showing through the Geographic Information System (GIS) the possibility of developing a more complete and accurate analysis of the area values, obtained directly from photos without scale correction, and after comparing it with area values obtained from aerial photography with correct scale referred in IGC (Brazilian Cartography and Geography Institute) guidelines, resulting in an error coefficient which shows area differences through two proposed study. Considering the aerial photography in three different years: 1962, 1977 and 2005 it is possible to affirm that the 2005’s images presented lower values of area difference (43, 48 square meters) than determined area values in reference chart and the 2005’s colored images has facilitated the photo interpretation of the landscape, becoming accurate the confronting traces and among land owners and consequently offering precision during land marking.

Estudo comparativo do custo da semeadura direta na cultura do milho utilizando duas metodologias

The present work is about a comparative study of two methodologies (MIALHE and ASABE), used to calculate the cost per hectare in the tillage operation in the culture of corn. The methodology of ASABE presents a higher cost per hectare in relation to the MIALHE proposal, being that the methodologies presents similar costs related to the depreciation expenses, accommodation and insurance. The differences were that in the ASABE proposal, the biggest expenses involved the payment of interest, fuel, lube and handwork, while in the MIALHE methodology, only the expense regarding to maintenance was more. The methodology of ASABE most suitable for management costs per hectare.

O trabalho visou obter o uso do solo da microbacia do Ribeirão Duas Águas – Botucatu (SP), através de imagem de satélite, a determinação das Áreas de Preservação Permanentes (APPs) e os conflitos existentes na área. As bases cartográficas foram: a carta planialtimétrica em formato digital do IBGE de 1969 e imagem de satélite de 2011. O SIG-IDRISI Selva foi utilizado para realizar o georreferenciamento da imagem, geração dos buffer de APPs e o overlay para obtenção dos conflitos de uso além da confecção do mapa temático final. No CartaLinx foi feita a delimitação da área de estudo e dos elementos (da rede de drenagem e das áreas de uso e cobertura). O uso da terra mostrou que a microbacia vem sendo ocupada por 1149,67ha de florestas naturais; 1073,45ha de reflorestamento; 737,67ha de pastagens; 691,93ha com solo exposto e 132,33ha de campo sujo. Já quanto as APPs, elas correspondem a 366,34ha de toda a microbacia, e destas 89,32ha estãosendo usadas para outros fins evidenciando assim seu conflito de uso. Desta forma, a caracterização do uso e cobertura da terra da região possibilitou uma infinidade de informações sobre a tipologia de manejo aplicado e na identificação de problemas ambientais que se configuram em decorrência de seu uso. Quanto aos conflitos em APPs uma parte significante da área da microbacia está sendo utilizada inadequadamente, não respeitando a legislação do Código Florestal Brasileiro.

Adequabilidade das áreas de vegetação ripária da microbacia do Córrego Comur - Botucatu (SP) em função da legislação ambiental

The inadequate soil use is an aggravating factor of the environmental degradation and ecological unbalance. The analysis of the use and covering of the soil, by information of Remote Sensing, constitutes a technique of great usefulness to the planning and administration of the ordered occupation and rational of the physical middle, besides making possible to evaluate and to monitor the preservation of areas of natural vegetation. This work sought to evaluate the conflicts of soil use in permanent preservation areas (PPA) in Stream Comur watershed - Botucatu (SP) through Geographical Information System and satellite image of 2009. The study area is located among the geographical coordinates 48o 23’ 04” to 48o 25’ 54” of longitude WGr. and 22o 44’ 42” to 22o 48” 12” of latitude S with an area of 1,719.6 ha. The results allowed to verify that the geoprocessing techniques were of fundamental importance in the identification of the areas of soil use, of APP and of conflicts among use and PPA where it leaves of the areas of APP is being used inadequately. In terms of environmental sustainability, it can be deduced that the watershed is very unfavorable, once it presents 70.67% of area used inadequately with sugarcane and pasture.

Geoprocessamento aplicado na caracterização morfométrica da microbacia do Ribeirão Descalvado - Botucatu (SP)

The objective of this study was to evaluate geoprocessing to morphometrically characterize the Ribeirão Descalvado micro watershed – Botucatu, SP by the Geographic Information System (GIS) – Selva for preservation, rationalization of its use and environmental restoration. The micro watershed is 2,228.61 ha between the geographic coordinates: 22° 50' 05" to 22° 54' 26" latitude S and 48° 22' 29" to 48° 26' 36" longitude W Gr. The cartographic basis was the planialtimetric chart of Botucatu (SP), 1: 50000 scale (IBGE, 1969), used for extraction of level, hydrography and topography curves to determine morphometric indices. The results showed that low values of drainage density associated with the presence of permeable rocks facilitates ground water infiltration which decreases surface runoff, erosion risks and environmental degradation. The low value of the shape factor supported by the circularity index shows that the micro watershed is more elongated and at lower risk of more pronounced floods. The roughness coefficient environmental parameter classified the micro watershed for forest and reforestation.
