The XII century towers, a benchmark of the Rome countryside almost cancelled. The safeguard plan by low cost uav and terrestrial DSM photogrammetry surveying and 3D Web GIS applications

“Giving a bird-fly look at the Rome countryside, throughout the Middle Age central period, it would show as if the multiple city towers has been widely spread around the territory” on a radial range of maximum thirty kilometers far from the Capitol Hill center (Carocci and Vendittelli, 2004). This is the consequence of the phenomenon identified with the “Incasalamento” neologism, described in depth in the following paper, intended as the general process of expansion of the urban society interests outside the downtown limits, started from the half of the XII and developed through all the XIII century, slowing down and ending in the following years. From the XIX century till today the architectural finds of this reality have raised the interest of many national and international scientists, which aimed to study and catalog them all to create a complete framework that, cause of its extension, didn’t allow yet attempting any element by element detailed analysis. From the described situation has started our plan of intervention, we will apply integrated survey methods and technologies of terrestrial and UAV near stereo-photogrammetry, by the use of low cost drones, more than action cameras and reflex on extensible rods, integrated and referenced with GPS and topographic survey. In the final project we intend to produce some 3D scaled and textured surface models of any artifact (almost two hundreds were firstly observed still standing), to singularly study the dimensions and structure, to analyze the building materials and details and to formulate an hypothesis about any function, based even on the position along the territory. These models, successively georeferenced, will be imported into a 2D and 3D WebGIS and organized in layers made visible on basemaps of reference, as much as on historical maps

RAPID WEBGIS DEVELOPMENT FOR EMERGENCY MANAGEMENT

The use of spatial data during emergency response and management helps to make faster and better decisions. Moreover spatial data should be as much updated as possible and easy to access. To face the challenge of rapid and updated data sharing the most efficient solution is largely considered the use of internet where the field of web mapping is constantly evolving. ITHACA (Information Technology for Humanitarian Assistance, Cooperation and Action) is a non profit association founded by Politecnico di Torino and SITI (Higher Institute for the Environmental Systems) as a joint project with the WFP (World Food Programme). The collaboration with the WFP drives some projects related to Early Warning Systems (i.e. flood and drought monitoring) and Early Impact Systems (e.g. rapid mapping and assessment through remote sensing systems). The Web GIS team has built and is continuously improving a complex architecture based entirely on Open Source tools. This architecture is composed by three main areas: the database environment, the server side logic and the client side logic. Each of them is implemented respecting the MCV (Model Controller View) pattern which means the separation of the different logic layers (database interaction, business logic and presentation). The MCV architecture allows to easily and fast build a Web GIS application for data viewing and exploration. In case of emergency data publication can be performed almost immediately as soon as data production is completed. The server side system is based on Python language and Django web development framework, while the client side on OpenLayers, GeoExt and Ext.js that manage data retrieval and user interface. The MCV pattern applied to javascript allows to keep the interface generation and data retrieval logic separated from the general application configuration, thus the server side environment can take care of the generation of the configuration file. The web application building process is data driven and can be considered as a view of the current architecture composed by data and data interaction tools. Once completely automated, the Web GIS application building process can be performed directly by the final user, that can customize data layers and controls to interact with the

Rockfall runout, Mount Cimone area, Emilia-Romagna Region, Italy

Numerous mass movements of different typology characterize both mountainous and piedmont sectors of the Emilia-Romagna Region (Apennine chain, North Italy). Although a less spatially frequent landslide typology within the region, rock falls represent severe threats to buildings, roads and persons due to their high propagation velocity. This paper presents an extract of the Emilia-Romagna regional map of the rock fall runout areas at a scale of 1:25,000. The analysis of rock fall runout areas was based upon a three-dimensional morphological method (TDM). The zone presented in the Main Map encompasses the area surrounding Mount Cimone, in the Emilia-Romagna Region. The proposed regional map of rockfall runout is noteworthy for planning actions and strategies aimed at the prevention and reduction of landslide risk at a regional scale

PENGEMBANGAN SISTEM INFORMASI GEOGRAFIS BERBASIS WEB INTERAKTIF MENGGUNAKAN FRAMEWORK GEOEXT (STUDI KASUS DATA PERTAMBANGAN PROVINSI ACEH)

Tumpang tindih wilayah penambangan dengan wilayah kehutanan maupun dengan pemegang konsesi pertambangan lainnya, serta tumpang tindih izin lokasi eksplorasi tambang telah menjadi perhatian serius bagi industri pertambangan di Indonesia. Kondisi tersebut akan dapat dihindari apabila pihak perusahaan dan pemerintah dapat melakukan pengecekan wilayah sebelum izin tambang dikeluarkan untuk suatu lokasi baru. Untuk pengecekan wilayah ini perlu dilakukan analisa GIS tertentu yang biasanya dilakukan menggunakan perangkat lunak GIS Desktop, namun perkembangan teknologi Internet dan GIS telah memungkinkan beberapa analisa GIS dilakukan melalui aplikasi web. Oleh karena itu, pada penelitian ini dibangun aplikasi WebGIS dengan menggunakan Framework GeoExt yang tidak hanya memberikan informasi geospasial sektor pertambangan melalui peta digital yang interaktif, tetapi juga menyediakan fungsionalitas untuk melakukan verifikasi lokasi baru yang akan diajukan sebagai wilayah tambang. Aplikasi ini dibangun dengan memanfaatkan layanan berbasis open source, yaitu GeoServer sebagai web server, PostgreSQL sebagai penyimpanan basis data, QGIS untuk mengelola data spasial dan Framework GeoExt untuk membangun user interface. Sebagai studi kasus, aplikasi WebGIS dikembangkan menggunakan data pertambangan Provinsi Aceh. Aplikasi ini dikembangkan menggunakan metode Rapid Application Development (RAD) dan diuji menggunakan metode Black-box testing. Analisis terhadap kelayakan (Usability) dari aplikasi WebGIS yang telah dibangun dilakukan menggunakan metode System Usability Scale (SUS). Analisis ini dilakukan dengan membagikan kuesioner SUS kepada 30 responden. Skor akhir yang diperoleh dari analisa ini adalah 71,67, yang tergolong dalam Acceptable Range dan berada pada grade C (Good). Hal ini menunjukkan bahwa aplikasi WebGIS ini layak untuk digunakan.Kata Kunci: WebGIS, GeoExt, pertambangan, tumpang tindih, RAD, SU

WebGIS as boundary tools between scientific geoinformation and disaster risk reduction action in volcanic areas

As the amount of spatial data is growing, there is increased interest in developing tools to explore, visualize and interpret them, with the final aim of informing decision making efficiently. Within the European MIAVITA project, we examined this issue in the case of volcanic areas, where existing geospatial databases are particularly complex due to the number of threats to be considered, including volcanic (e.g. lava flows, ash fall) and non-volcanic hazards, such as landslides or tsunamis. We involved a group of hazard and risk analysts and managers, civil security officers, GIS analysts and system developers to design a Web-based geographical information system (WebGIS). We tested the system at the Mount Cameroon volcano, taking advantage of a complex hazard and risk geographical database. This study enabled identifying key requirements for such tools in volcanic areas, such as the need to manage user privileges differently according to their profile and the status of the volcano. This work also highlights that, in addition to the development of large geoinformation clearinghouses, there is a need for site-specific information systems focused on working procedures of users, in order to fill the last gap between data producers and users
