Parte da construção de uma geografia renovada, amparada numa metodologia de pesquisa maleável, indaga sobre as possibilidades de subverter as funções técnicas do sistema de informação geográfica (SIG), utilizando-se de suas bases cartográficas, todavia, buscando uma produção alternativa ao sugestionado por meio de softwares de mapeamento. Para tanto, a proposta metodológica aqui apresentada, conduz a uma produção cartográfica subsidiada por programas gratuitamente disponíveis e de fácil manipulação, tais quais: Google Earth, editores de slides e editores de figuras. Procura-se, desse modo, conferir autonomia a geógrafos e demais pesquisadores, buscando contribuir para a discussão acerca da produção de cartografias mais flexíveis, menos ancoradas nas certezas que apenas o espaço euclidiano pode abrigar.Abstract: Part of building a renewed geography, supported in a flexible methodology research, we ask for possibilities to subvert the technical functions of geographic information system (GIS), using their cartographic databases, although, looking for an alternative way to the cartographic production that is usually induced by the standard of mapping software’s. Due this, the methodology introduced in this article comes to subsidize a cartographic production by the use of programs that have free access and are easy to handle, as such: Google Earth, editor of figures and editor of slides. Therewith we intend empower geographers and other researchers expecting that this proposal contribute to the discussion about producing a flexible cartography, less rooted in the certainty that only the Euclidean space can shelter.Keywords: medium-technical-scientific-informational; cartography; alternative methodology; geographic information system.

AbstractGoogle Earth imagery is used here in conjunction with a Geographic Information System to identify transverse drainages and recreate palaeodrainage in an internally draining region in Iran. At least 35 water gaps and 34 wind gaps are shown to exist in the region, as well as evidence for an integrated palaeodrainage that originated north of the internally draining region and emptied into the Mand watershed to the west. The topographic characteristics of the transverse drainages suggest a strong control by local topography, and support formation of the internally draining region by basin filling and overflow. Both climatic and tectonic factors may have controlled the loss of external connectivity.

<p>Este artigo apresenta a construção de um Sistema de Informação Geográfica (SIG), disponível na <em>web</em>, como ferramenta para divulgar informações atualizadas sobre o agronegócio do babaçu no estado do Piauí, Brasil. O SIG GeoBabaçu foi desenvolvido utilizando a plataforma GeoServer e foi composto de duas partes:1) site<em> web</em> que mostra informações gerais sobre o babaçu e sobre os municípios produtores; 2) banco de dados geográficos com a disponibilização dos mapas da distribuição espacial do babaçu nos municípios pesquisados. Na construção do Banco de Dados Geográficos foram utilizados o sistema gerenciador de banco de dados PostgreSQL 9.3 + PostGIS 2.1., em conjunto com o Sistema de informação Geográfica QGIS. Para o mapeamento da distribuição espacial do babaçu foram selecionados os 25 municípios que apresentaram produção média mínima de cinco toneladas de amêndoas entre os anos de 2006 e 2013. Foram utilizadas imagens RapidEye, ortorretificadas com resolução espacial de 5 metros, composição R5G4B3 para a geração dos mapas. As imagens foram segmentadas e classificadas no <em>software </em>eCognition 8.7 e reclassificadas manualmente no módulo ArcMap do ArcGis<em> </em>10.2.2, com o apoio de imagens do Google Earth Pro 7.1.5.1557. O levantamento dos dados de localização dos babaçuais foi realizado utilizando equipamentos GPS de navegação com precisão de 10 metros.

Lulc Change

The need for built-up area increases along with a rise in population growth in many regions. This phenomenon leads to a tremendous change in agricultural land and decrease in the environmental carrying capacity. Therefore, this study aims to determine Land Use and Land Cover (LULC) dynamics and the drivers used for its modeling in 2030. This is a quantitative study, which uses the dynamic models of Geographic Information System (GIS) and Markov-CA. Data were obtained from the CNES-Airbus satellite imageries in 2009, 2014, and 2019 by using Google Earth at East Cirebon. The drivers include road density, distance to CBD, total population, distance to settlements, land slope and distance to rivers. The interaction between drivers and LULC change was analyzed using binary logistic regression. The results showed that the rise of built-up area reached 36.4 percent and causes the loss of 0.78 km2 of agricultural land from 2009 to 2019. The LULC simulation in 2030 shows an increase in the built-up area by 82.85 percent with probabilities above 0.6. Meanwhile the significant drivers for changes include road density and distance to settlements. In conclusion, efforts to reduce LULC change in agricultural land into built-up area is by re-strengthening spatial planning-based environmental awareness for the community.

<p>Erupsi Gunungapi Merapi tahun 2010 mengakibatkan banyak korban jiwa, kerusakan aset dan kerugian di berbagai bidang. Untuk meminimalkan korban jiwa, kerusakan dan kerugian, diperlukan upaya pengurangan risiko bencana (PRB). Salah satu upaya yang dilakukan adalah program desa bersaudara (<em>sister village</em>) yang digagas oleh Pemerintah Kabupaten Magelang melalui Badan Penanggulangan Bencana Daerah (BPBD). Program desa bersaudara ini bertujuan agar ada kepastian tempat pengungsian, mengurangi kesemrawutan proses pengungsian serta memudahkan pelayanan pengungsi. Program ini dapat memanfaatan Sistem Informasi Geografis/<em>Geographic Information System</em> (GIS) yang berbasis web (<em>WebGIS</em>). <em>WebGIS</em> mampu mendiseminasikan peta yang dihasilkan dalam program desa bersaudara, misalnya peta jalur evakuasi. Makalah ini bertujuan untuk mendiskripsikan pemanfataan <em>WebGIS</em> dalam mendukung program desa bersaudara, dengan mengambil kasus di Desa Ngargomulyo (desa rawan bencana) dan Desa Tamanagung (desa penyangga/ penerima pengungsi). Metodenya adalah memaparkan proses pemetaan jalur evakuasi. Proses penyusunan peta tersebut terbagi empat tahap:   survei lapangan, penyiapan data spasial, coding dan publikasi. Hasilnya adalah tampilan peta jalur evakuasi yang bisa diakses oleh siapapun tanpa menggunakan aplikasi GIS yang memudahkan masyarakat pengungsi, penerima pengungsi, pemerintah maupun parapihak, mengetahui asal pengungsi, jalur evakuasi dan titik pengungsian. Penelitian ini menyimpulkan bahwa pemetaan <em>WebGIS</em> dapat mendukung upaya PRB dengan keunggulan bisa dijangkau pengguna secara sangat luas.<strong></strong></p><p><strong>Kata kunci</strong>: desa bersaudara, <em>sister village</em>, pemetaan jalur evakuasi, <em>gis</em>, <em>webgis</em></p>
