A Malha Viária Digital geral do Estado de Rondônia, edição de outubro/2010 - Escala 1:20.000 para zona rural e 1:10.000 para zona urbana, representa, atualmente, a informação mais atualizada sobre as vias de acesso do Estado. O projeto foi desenvolvido e executado pelo Sistema de Proteção da Amazônia -SIPAM-CR-PV, iniciado no ano de 2004, compreendendo a execução do levantamento de campo por rastreamento com equipamento GPS Topográfico, com apoio financeiro e logística em parceria com o Instituto Brasileiro de Geografia e Estatística - IBGE/UE/RO, Instituto Nacional de Colonização e Reforma Agrária - INCRA/SR/17, Secretaria de Estado do Planejamento e Coordenação Geral - SEPLAN/RO e Departamento de Estradas de Rodagem de Rondônia – DER/RO, com participações especiais de algumas prefeituras municipais e do Instituto Chico Mendes de Conservação da Biodiversidade - ICMBIO/RO. O levantamento contemplou de forma precisa, o traçado representativo cartográfico e a identificação das estradas Federais, Estaduais e Municipais, com seus trechos pavimentados e não pavimentados, devidamente classificados em separado, contemplando preferencialmente a zona rural dos 52 municípios do Estado de Rondônia. O trabalho compreendeu também o rastreamento pontual/estático da localização geográfica de centenas de pontos e/ou locais de referência, tais como: Estabelecimentos comerciais; Estabelecimentos Industriais; Escolas; Igrejas; Postos de saúde; Povoados; Lugarejos; Pontes e Bueiros sobre os principais rios; Usinas geradoras de energia elétrica; Nome de algumas propriedades rurais, etc., entre outros. Consta também, o levantamento de várias pistas de pouso. A utilização digital das informações levantadas e cartografadas favorecem os trabalhos de georreferenciamento de imagens por satélite e auxiliar futuros trabalhos de correção na representação cartográfica de limites municipais. Os dados levantados compõem a Base Cartográfica digital do Estado de Rondônia e se constitui num importante suporte para o planejamento e execução de ações públicas sociais e de operações de campo, como também serve de base para cálculo de recursos públicos financeiros destinados aos municípios, em razão da quilometragem de estradas existentes em cada um. Favorece o entendimento da realidade econômica do Estado, servindo ainda, de guia rodoviário de precisão. O levantamento teve início no mês de março de 2004 e se estendeu até o mês de outubro de 2010, compreendendo 553 dias de serviço de campo. Obviamente, considerando o intervalo de tempo desde o seu inicio, e a constante abertura de novas estradas e expansão populacional rural em alguns municípios, certamente existirão novos elementos que não estão representados nesta edição. Desta forma, pretendemos planejar e executar algumas missões de campo para levantamento de revisão/atualização em alguns municípios, principalmente no tocante às estradas construidas ou pavimentadas recentemente. Apesar de termos levantado algumas vias urbanas em algumas cidades e vilas, não foi o objetivo original deste projeto. Portanto, é importante esclarecer que os trabalhos, preferencialmente, concentraram-se na zona rural dos municípios.

This data set provides a digital map of soil orders for the Ji-Parana River Basin, in the state of Rondonia, Brazil (Western Amazonia). Soil orders were manually digitized from a 1:500,000 map from EMBRAPA originally published in 1983. Oxisols and Ultisols are the predominant soil types in the basin, encompassing 47% and 24% of the total drainage area, respectively. Entisols cover 14%, Alfisols 13% and Eptisols 2% of the basin (Ballester et al., 2003). One data file is provided in ESRI ArcGIS Shapefile format compressed into a single zip file (*.zip).

This data set provides estimates of watershed deforestation, as a proportion of the total area of watersheds, in Rondonia, Brazil for 1999. Deforestation maps were determined for the main agricultural and surrounding forested areas of Rondonia using multiple Landsat TM scenes (Biggs et al. 2008). Cumulative deforestation estimates were derived from this time series of Landsat scenes from 1975 to 1999. To obtain watershed-level estimates of deforestation, watershed boundaries and stream networks were delineated by a flow accumulation algorithm using a 90-m resolution digital elevation model (DEM) from NASA's Shuttle Radar Topography Mission (SRTM). The results were watersheds of seven Strahler stream orders (1-7) with stream networks that closely matched those of the 1:100,000 topographic maps for the area. The watershed boundaries, classified by stream order, were overlain on the time series of deforestation maps to determine the cumulative deforestation extent in 1999.

This data set contains six ESRI ArcGIS shapefiles of the watershed boundaries for streams orders 2-7, the smallest watershed (second order) to the largest inclusive watershed (seventh order). The cumulative deforestation estimates, as a proportion of total area for each watershed, are available as a comma-delimited text file that can be related to the individual watershed boundary shapefiles. Cumulative deforestation data are available for first order streams, although not as a shapefile.

There are six zipped ESRI ArcGIS shapefiles (*.zip) and one ASCII comma separated file with this data set.

description: ABSTRACT: This data set provides four related spatial data products for four study areas across the Brazilian Amazon: Manaus, Amazonas; Tapajos National Forest, Para Western (Santarem); Rio Branco, Acre; and Rondonia, Rondonia. Products include vector data showing (1) roads, (2) rivers, and (3) hypsography and (4) digital elevation model (DEM) images that were encoded from the hypsography vectors. There are 15 data files with this data set which includes 12 compressed *.zip files containing ArcInfo shape files and 3 GeoTIFFS.This data set contains vector data showing roads, rivers, and hypsography for each study area in ESRI ArcGIS shapefile format. The vectors were hand-digitized by the Images Company in Brazil from paper maps produced by the Brazilian government. Depending on the scale of the original maps, the digitization errors vary. For some maps, some vectors are missing. Data were manually checked for duplicate or extra vectors. These data sets were derived from several map sheets produced from aerial coverages dating from 1974 to 1978.The DEM images were encoded from the hypsography vectors and are provided in GeoTIFF format. The attribute value associated with each line and point in the vector segment is encoded into the image channel; the image channel is then filled in by interpolating image data between encoded vector data. For each DEM: 1 image channel with pixel resolution = 25m x 25m. DEM images are provided for Manaus, Tapajos National Forest, and Rondonia. The files for Rio Branco were unusable due to a documentation error.DATA QUALITY STATEMENT: The Data Center has determined that there are questions about the quality of the data reported in this data set. The data set has missing or incomplete data, metadata, or other documentation that diminishes the usability of the products. KNOWN PROBLEMS:The data providers note that due to limited resources, these data have been neither validated nor quality-assured for general use. For that reason, extreme caution is advised when considering the use of these data. - Any use of the derived data is not recommended because the results have not been validated.- However, the DEM, vectors, and orthorectified SAR data (related data set) can be used if the user understands how these were produced and accepts the limitations.; abstract: ABSTRACT: This data set provides four related spatial data products for four study areas across the Brazilian Amazon: Manaus, Amazonas; Tapajos National Forest, Para Western (Santarem); Rio Branco, Acre; and Rondonia, Rondonia.

This data set includes 16 zipped archives of shapefiles of cities, rivers and streams, roads, and study area boundaries of several Amazonian study sites: Altamira, Santarem, Bragantina, and Ponta de Pedras, in the state of Para, and 1 site at Machadinho D'Oeste, in the state of Rondonia. Data from Brazil were digitized from Instituto Nacional de Colonizacao e Reforma Agraria (INCRA) maps and other data from Instituto Brasileiro de Geografia e Estatistica (IBGE). These products were prepared in the 2000-2004 time period. The data of creation for the source material is unknown.
