    1285 Words  | 3 Pages

    Geological structure plays a crucial role in determining a wide field of relief forms, even in areas where exogenetic factors are regarded as the dominant ones in the landscape (Ahnert 1998; Bloom 1998; Ritter et al. 2002). In recent years Digital Elevation Model (DEM) data and Geographical Information System (GIS) technologies have been extensively used to determine the morphometric properties of tectonically active regions. In addition the use of Remote Sensing and GIS techniques to evaluate the

Conclusion In this assignment spatial analysis was defined as the “set of methods used where the results of the object change when the object changes its location” (Longley et al. 2005). The various models of spatial analysis was discussed namely queries, transformations, measures and spatial interpolation. Under transformation buffering, point-in-polygon, polygon overlay are some operations that were discussed. Under measure the distance and length

    variables Our results showed that species clusters differed in terms of analysed environmental variables. Generally, temperature-related variables (BIO1, BIO3, BIO4 and BIO9) were the key factors responsible for differentiation between the clusters. Elevation and variables connected with the terrain sculpture (WI, TI, TRI and MRVBF) were among the most important topographic variables separating species clusters. The influence of the geological variables (related to the bedrock) was relatively weak, but

    The earliest aerial photograph reviewed for Phase I ESA purposes was taken in 1943. The previous alignment of Highway 101, now called Santa Maria Way (or Business U.S. 101), is bordering the site to the west. An unpaved road had been constructed through the southern portion of the site that appears to be the access road to oil well Holmes No. 1, which is just east of the site, connecting it to Highway 101. The unpaved road through the site is looped with what appears to be four round tanks in

    and objectives: Exhibition design has evolved highly within the past century. What was once a fairly straight forward design discipline, has advanced into a multi-disciplinary area that goes far beyond common practices. With the introduction of new digital techniques i.e. 3D modelling programs, CAD software, etc., a new perspective has been put onto the overall design process of exhibition design. This paper seeks to explore the advantages of using these new design techniques in combination with traditional

Assigning the intensity value to a pixel and defines radiometric properties of the image (Schenk, 1999) From the point of view of the application, the digital image is presented as a matrix I that are consist of r = 1, and so on, R is rows and j = 1, and so on, C is columns. For that, the elements of the matrix that are carry intensity values. By that, depending on the type of image will make the matrix

These results generally coincided with Schulz’s and Diendorfer’s (1999) study in Austria. As opposed to the findings of Smorgonskiy et al. (2013), Schulz and Diendorfer (1999) focused on a smaller area where the lightning location system had the best performance, and they overlapped it with elevations given by the GLOBE digital elevation model. They discovered that after an

  • The Use of Geographic Information Systems in Real Estate Appraisal

    5011 Words  | 11 Pages

    The Use of Geographic Information Systems in Real Estate Appraisal Abstract Appraisers need to show the reasoning behind their value opinions by discussing important spatial relationships and their likely effect on value. Geographic information systems (GIS) can be used to analyze these relationships and to show why a client should select an appraiser who has this level of information. Gilbert Castle has noted that real estate is essentially a game of information arbitrage. The likely

    While the transition of television to a digital technology with its improved picture and sound quality has been a much publicized and controversial process, television's venerable ancestor, radio, has stayed in the background. But this year, in the United States, radio broadcasting is making its own digital leap. Two start-ups are introducing a new type of radio broadcast--subscription-based digital audio sent from satellites. With satellite digital audio radio services (SDARS), as they're called

  • GUESS Model Of Soil Erosion Analysis

    823 Words  | 2 Pages

    The GUESS model for soil erosion, which was developed by Rose et al. (1983) illustrated the processes of soil erosion, transportation and deposition along hillside. Therefore the model can be used to predict on- and off-site effects. Soil erosion at any position on the slope and at any time during the storm is related to a sediment flux. It depends on the sediment concentration and the hydrological conditions. This model is designed as a guide to farmers, scientists and other workers relevant with

    From the very early day of human beings, did transport appear. It is the result of human desire for mobility and exploration. Transport or transportation is the movement of people and goods from one place to another. It serves several functions to economy and human society but as time passed by, along with growth transportation, environment especially landscape and heritage have been badly affected. According to Matthew et.al (2007), “Human activities within a landscape often result in land use
