Site characterization activities involving a variety of different tools and techniques are a key component of any environmental rehabilitation program. Depending on the specific characteristics and requirements of the project, a range of tools can be used to characterize the surface and subsurface conditions. The results will be subject to specific limitations which will apply to a particular tool in terms of the depth investigated and the resolution of the measurements obtained as a result of the sensor capacity and background noise conditions. This paper presents a methodology that can be used to evaluate the relative merits of alternative sampling plans for a site and assist in identifying the optimal sampling plan taking into account the amount and type of prior information. This methodology allows new test results to be incorporated in real time as "prior information" as the site investigation proceeds. The methodology is implemented using a geographic information system (GIS) and a knowledge base system (KBS). Factors considered in the methodology include the effective measured area, the likely target characteristics, surface and subsurface noise conditions, and the level of confidence that exists about the possible source location as a result of prior studies at the site. The results of a sensitivity study are presented. An example is used to demonstrate the capability of the prototype system to assess different test configurations.Key Words: characterization, GIS, KBS, planning, quality.

With the digital development of city construction, the construction of three-dimensional Geographic Information System plays an important role for the urban construction planning and decision-making. 3D urban planning geographic information management systems need to be able to put different spatial data, information of urban construction, urban planning information into the same platform. The integration of information resources whick provids a variety of spatial information based on the intelligent application services is the core. This article puts urban planning geographic information management related to business needs in-depth analysis, and put forward a three-dimensional geographic information model which is used for integrated management of data and can be dynamically adjusted for urban planning and management of business processes.

Abstract. This study presents a methodology for forecasting the extent of inundation and depth of distribution during typhoons in real-time. The proposed approach involves the construction of ARX and ARMAX models capable of predicting water-levels at the locations of on-site gauging stations and representative points located at the outlets of the sub-areas obtained by terrain analysis using a geographic information system. The models are constructed based on historical typhoon data and the results of numerical simulations related to inundation. A database comprising layers of inundation maps related to water-levels in each sub-area based on the assumption of flat-water and the digital elevation model (DEM) of the area were assembled prior to the typhoon. Water-levels during the typhoon are forecast using the constructed models, whereupon inundation sub-maps associated with the forecasted water-levels are extracted from the database. The resulting inundation map is comparable to that obtained using Synthetic Aperture Radar. Processing can be conducted in real-time and requires very little computational resources. This provides valuable lead time in which to conduct efforts aimed at damage mitigation during a typhoon.

Programming Interface

Kecepatan akses informasi menjadi pembahasan cukup penting dalam pembuatan aplikasi. Teknologi yang mulai merambah pada dunia serba mobile menjadikan kecepatan dan kepraktisan akses informasi menjadi prioritas utama dalam pelayanan fitur sebuah aplikasi. Aktivitas logistik yang melibatkan banyak komponen pengguna memerlukan suatu sistem informasi yang dapat memberikan layanan informasi cepat dan akurat. Pada penelitian ini penulis membuat Real time system berbasis Geographic Information System, untuk mengakomodasi kebutuhan komunikasi data lokasi antara kurir dan outlet. Metode yang digunakan dalam penelitian ini memanfaatkan Aplication Programming Interface yang disediakan oleh Google, yaitu Google Maps API. Data spasial yang digunakan pada penelitian ini mengambil dari data Maps milik Google. Hasil penelitian ini adalah suatu sistem yang saling berkomunikasi mengirim data spasial berupa latitude, longitude, distance, time estimation, route, dan real time marker. Penggunaan GIS berbasis Google Maps API ini sangat efektif dalam membantu estimasi dan monitoring proses pengiriman dan jual beli.
