Agricultural drain tile systems are a significant influence on the condition of wetlands and waterways. The influence of these systems is often difficult to determine since installation records are incomplete or were never kept. Using a modified decision class tree and raster analysis in ArcGIS, a model for predicting the location of land drained by subsurface systems was evaluated. The three-c...

Cellular automata (CA) is increasingly used to simulate various dynamic courses, e.g. urban spatial growth, forest fire spread and soil desertification. CA simulates these courses with iterative evolvements. Through simple and partial rules to form complex space structures and patterns, CA can express complex systems which are difficult to perform only with mathematical formulas. In combination...

This paper presents a novel hyperspectral feature-extraction toolkit that provides a simple, automated, and accurate approach to materials classification from hyperspectral imagery (HSI). The proposed toolkit is built as an extension to the state-of-the-art technology in automated feature extraction, the Feature Analyst software suite. Feature Analyst uses, along with spectral information, feat...

Measurements of porosity and pore size distribution provide important data on the physical properties of soils. This paper presents a digital image method for the analysis of soil pores. In the analysis of soil thin sections, the image threshold separating pore space from the surrounding solid, as well as the capillary pore size threshold separating air pores and capillary pores, was obtained b...

Orphninae (Coleoptera: Scarabaeidae) are represented in the New World by the tribe Aegidiini, which is comprised of four genera (Paulian 1984). Examination of material collected in Ecuador revealed a series of the Aegidiini specimens from an undescribed species that cannot be classified as a member of one of the known genera. The new species is herein described and a new genus is established. A...

Remote sensing change detection technique has been an important method to observe the land use change. At present, there are lots of algorithms of land use change detection, but there isn’t an existing integrating frame and platform: the new-developed change detection platforms have limitation of supporting data sources and developing always consumes long time; while the change detection module...

DAS Bendo adalah sebagian daerah yang berkontribusi terhadap kejadian banjir di Kabupaten Banyuwangi. Guna mengetahui tingkat kerawanan dipakai parameter curah hujan, kemiringan lereng, jenis tanah, penggunaan lahan, ketinggian dan kerapatan sungai dalam penelitian ini. Metode scoring overlay digunakan untuk mengolah melalui software ArcGIS 10.4 sehingga dapat dihasilkan peta banjir. Peta cukup...

Landslides as major natural geological hazards often result in significant harm to people and property. Between 20 and 31 August, 2002, Typhoon Rusa hit the Gangneung area as a storm associated with heavy rainfall. The maximum daily rainfall amounted to 609 mm, with 80 mm per hour. The consequence was the death of 266 people. Damage to property amounted to an approximate value of US$ 8 billion....
