Cultural Heritage is recognized as a priceless asset of human being, which exposes the humanity's achievements over centuries. The need for documentation and preservation of cultural heritage is well known worldwide. Digital surveying techniques are playing a catalytic role towards recording and documentation of cultural heritage. This chapter describes the methodological and technological aspects of image-based recording and documentation approaches acting as the vehicle for the digital surveying of cultural heritage. The chapter not only describes the different technologies and techniques used but also goes to the extent of clarifying several applied implementation issues. Three different examples and application case studies from a small, a medium and a large-scale cultural heritage objects are provided to demonstrate the developments.

The study was motivated by the need to determine the spatial variation of ET and to test the applicability of RS based methods in arid to semi-arid climates with limited ground-based measurements. In this paper we present results of an effort of determining spatial actual evapotranspiration in the Limpopo basin, the Notwane subcatchment in the south-eastern part of Botswana, using remote sensing data from MODIS and Landsat Data sets. The Simplified Surface Energy Balance Index (S-SEBI) was applied to determine actual evapotranspiration using the seven bands of Landsat and MODIS surface reflectance and temperature channels. Three different dates were used to estimate ET from both Landsat and MODIS scenes. The estimated ET values from the two sensors show approximately equally comparable results. An assessment was also conducted to determine the factors influencing evapotranspiration. No strong correlation was identified for ET against the five factors investigated: Net radiation, NDVI, Surface Temperature, emissivity and surface albedo.
该研究的动机是需要确定ET的空间变化,并在有限的地面测量条件下测试基于RS的方法在干旱至半干旱气候下的适用性。在本文中,我们介绍了利用MODIS和Landsat数据集的遥感数据确定博茨瓦纳东南部notane小流域林波波流域空间实际蒸散量的结果。采用简化地表能量平衡指数(S-SEBI),利用Landsat和MODIS地表反射率和温度通道的7个波段确定实际蒸散量。使用了三个不同的日期来估算来自Landsat和MODIS场景的ET。两个传感器估算的ET值显示出大致相等的可比较结果。还进行了评估,以确定影响蒸散发的因素。ET与净辐射、NDVI、地表温度、发射率和地表反照率这5个因子之间没有很强的相关性。

The advent of user-generated content, crowdsourcing and other forms of lay data generation have led to opposing arguments about the quality and reliability of data in the geoweb. The main focus of this chapter is an ‘experiment' to test the quality, validity and lay monitoring of volunteered geographic information (VGI) data. Given the growing importance of VGI, in particular its very different sources and potential uses, it is important that we also consider how this movement affects the ways in which we re-envision the pedagogy of geographic education. Accordingly, a sub-theme of this paper focuses on the manner in which the VGI experiment is undertaken: the experiment is run with students as a means of complementing their otherwise technical GIS training with primary research that exposes them to the wider social issues and debates relating to geographic data. We discuss the implications of this research project both for observers of the development of VGI and the pedagogy of GIS teaching and learning.
用户生成内容、众包和其他形式的外行数据生成的出现,导致了关于geoweb中数据质量和可靠性的对立争论。本章的主要重点是一个“实验”来测试自愿地理信息(VGI)数据的质量、有效性和lay - monitoring。鉴于地理地理标志日益增长的重要性,特别是其非常不同的来源和潜在用途,我们也必须考虑这一运动如何影响我们重新设想地理教育教学法的方式。因此,本文的一个副主题侧重于VGI实验的进行方式:该实验是与学生一起进行的,作为补充他们的技术GIS培训的一种手段,通过初级研究使他们接触到与地理数据有关的更广泛的社会问题和辩论。我们讨论了该研究项目对VGI发展观察者和GIS教学方法的影响。

Image segmentation among overlapping land cover areas in satellite images is a very crucial task. Detection of belongingness is the important problem for classifying mixed pixels. This paper proposes an approach for pixel classification using a hybrid approach of Fuzzy C-Means and Cellular automata methods. This new unsupervised method is able to detect clusters using 2-Dimensional Cellular Automata model based on fuzzy segmentations. This approach detects the overlapping regions in remote sensing images by uncertainties using fuzzy set membership values. As a discrete, dynamical system, cellular automaton explores uniformly interconnected cells with states. In the second phase of our method, we utilize a 2-dimensional cellular automata to prioritize allocations of mixed pixels among overlapping land cover areas. We experiment our method on Indian Ajoy river watershed area. The clustered regions are compared with well-known FCM and K-Means methods and also with the ground truth knowledge. The results show the superiority of our new method.
卫星图像中重叠土地覆盖区域的图像分割是一项非常关键的任务。归属检测是混合像素分类的重要问题。本文提出了一种混合模糊c均值和元胞自动机方法的像素分类方法。该方法采用基于模糊分割的二维元胞自动机模型进行聚类检测。该方法利用模糊集隶属度值的不确定性来检测遥感图像中的重叠区域。作为一个离散的动态系统,元胞自动机探索具有状态的均匀相互连接的细胞。在我们的方法的第二阶段,我们利用二维元胞自动机来优先分配重叠的土地覆盖区域之间的混合像素。我们在印度阿乔伊河流域进行了试验。将聚类区域与已知的FCM和K-Means方法以及地面真值知识进行比较。结果表明了新方法的优越性。

A forest patterns map over a large extent at high spatial resolution is a heavily computation task but is critical to most regions. There are two major difficulties in generating the classification maps at regional scale: large training points sets and expensive computation cost in classifier modelling. As one of the most well-known Volunteered Geographic Information (VGI) initiatives, OpenstreetMap contributes not only on road network distributions, but the potential of justify land cover and land use. Google Earth Engine is a platform designed for cloud-based mapping with a strong computing power. In this study, we proposed a new approach to generating forest cover map and quantifying road-caused forest fragmentations by using OpenstreetMap in conjunction with remote sensing dataset stored in Google Earth Engine. Additionally, the landscape metrics produced after incorporating OpenStreetMap (OSM) with the forest spatial pattern layers from our output indicated significant levels of forest fragmentation in Yucatan peninsula.
大范围的高空间分辨率森林格局图是一项繁重的计算任务,但对大多数地区来说是至关重要的。在区域尺度上生成分类图存在两个主要困难:训练点集大和分类器建模计算成本高。作为最著名的志愿地理信息(VGI)倡议之一,OpenstreetMap不仅有助于道路网络分布,还有助于证明土地覆盖和土地利用的合理性。谷歌地球引擎是一个为基于云的地图设计的平台,具有强大的计算能力。在这项研究中,我们提出了一种利用OpenstreetMap与Google Earth Engine中存储的遥感数据集相结合的方法来生成森林覆盖地图和量化道路造成的森林碎片化。此外,将OpenStreetMap (OSM)与我们输出的森林空间格局层结合后产生的景观指标表明,尤卡坦半岛的森林破碎化程度很高。

Wild edible fungi are non-timber forest products that have great relevance for forest communities in central Mexico. Texcaltitlán is a rural community known for its traditional ecological knowledge on the use and identification of wild edible mushrooms. The aim of this work is to link Geographic Information Systems and Traditional Ecological Knowledge, in order to generate Mycological Information Systems. This is a qualitative, quantitative and exploratory research, which seeks to determine the usefulness of Geographic Information Systems (GIS) to systematize and locate mycological resources for use as a tourist attraction. The results show the existence of a wide variety of edible mushrooms in the region, along with a wide mycological traditional knowledge. Both aspects reflect the existence of unique natural and cultural features that can be the basis to build a unique tourism product in central Mexico. It is concluded that GIS are useful tools to build a multifunctional vision of mushrooms.

Globalization is an inevitable integrating process and vital to the world economy but it generates many challenges towards the integration of “economic independence” of the nation states like (a) economic integration through investment/trade and capital flow, (b) initiating multilateral political interaction between the countries, and (c) diffusion of dominant cultural values and beliefs over other cultures. globalization accelerates structural change, which alters the industrial structure of host countries, for instance the excessive use of natural resources and contributes to the physical environmental deterioration. Further, globalization transmits and magnifies market failures and policy distortions if not properly addressed. The chapter attempts to (a) identify the key links between globalization and environment deterioration, (b) identify some issues in multilateral economic agreements in trade, finance, investments, and intellectual property rights that affect environmental sustainability, (c) identify and review priority policy issues affecting multilateral economic agreements on environment issues.
全球化是一个不可避免的一体化过程,对世界经济至关重要,但它对民族国家的“经济独立”一体化产生了许多挑战,如:(a)通过投资/贸易和资本流动实现经济一体化,(b)发起国家之间的多边政治互动,以及(c)对其他文化的主导文化价值观和信仰的扩散。全球化加速了结构变化,改变了东道国的产业结构,例如过度利用自然资源,并导致自然环境恶化。此外,如果处理不当,全球化会传播和放大市场失灵和政策扭曲。本章试图(a)确定全球化与环境恶化之间的关键联系,(b)确定贸易、金融、投资和知识产权多边经济协定中影响环境可持续性的一些问题,(c)确定和审查影响有关环境问题的多边经济协定的优先政策问题。
