The availability of new mobile devices (tablets and smartphones) equipped with many sensors is changing or, better, enriching the way we monitor and sense the world that surrounds us. The internet has permeated completely not only our scientific and technological development, but also our life. Only some years ago, we used geospatial data and GIS software installed within our computers. Nowadays, data and operators are provided via the net by means of distributed and shared geo-services and a simple and powerless mobile device is enough to connect them. The possibility of interaction has become not only faster and more user friendly but also active, being individuals and communities free of adding, deleting, and changing contents in real time in the new GeoWeb2.0. This chapter explores GeoWeb2.0.

<p class="ArticleTitle">In recent years, the increasingly innovative and diverse mobile devices have significantly promoted the mobile device-based shopping. What factors influence this kind of shopping? Will consumers purchase things with mobile devices? These are two topics that need to be explored. Through the literature analysis and the empirical research, this study aims to analyze the quality of information, system, service and mobile devices on the mobile device-based shopping platform. Moreover, it studies the attitude of consumers towards mobile device-based shopping, their willingness to adopt the shopping method and the behavioral relationship model in the actual mobile device-based shopping as well as compares the groups of different frequencies of the Internet use in terms of the relationship model.</p>  With the convenient sampling, this study made an investigation among some of those who had experienced shopping on such mobile devices as tablets or smart phones. The 765 retrieved valid copies of questionnaire were divided into three groups—“often”, “average” and “seldom” according to the frequency consumers undertook mobile device-based shopping and were then compared. The results showed that there were significant differences among the three groups in four relationship paths, including: 1) the information quality of the mobile device-based shopping platform has more significant positive influence on consumers’ attitude path of mobile device-based shopping in the “average” group than in the other two; 2) the service quality of the mobile device-based shopping platform has more significant positive influence on consumers’ attitude path of mobile device-based shopping in the “seldom” group than in the other two; 3) the preference for mobile device-based shopping has much significant positive influence on the behavior path of mobile device-based shopping in the “often” group. According to the research results, different groups have different behavior models. These results can serve as reference information in the decision-making of those who establish mobile device-based shopping platforms and manufacture mobile devices.

DEM (Digital Elevation Models) is the best way to interpret topography on the ground. In recent years, lidar technology allows to create more accurate elevation models. However, the problem is this technology is not common all over the world. Also if Lidar data are not provided by government agencies freely, people have to pay lots of money to reach these point clouds. In this article, we will discuss how we can create digital elevation model from less accurate mobile devices’ GPS data. Moreover, we will evaluate these data on the same mobile device which we collected data to reduce cost of this modeling.

OpenStreetMap is a collaborative web-mapping project that collects geospatial data to create and distribute online maps, freely available to anyone with an Internet connection. Once accessed, OpenStreetMap allows Internet users to contribute and edit geospatial data, effectively making it the mapping equivalent of Wikipedia. OpenStreetMap is maintained by volunteer cartographers from around the world who use GPS devices, portable cameras, and laptops for field mapping. Collected data are complemented with digitised open source aerial photography and free maps from the governmental and commercial sources. This report provides a summary of OpenStreetMap as a remarkable example of participatory geographic information systems (GIS).

Pertumbuhan akses informasi pada saat sekarang ini berjalan secara pesat. Masyarakat atau user untuk mendapatkan data atau informasi yang akurat, aktual, serta cepat dan mudah sekarang bukanlah hal sulit. Perkembangan internet pada saat ini semakin pesat dan tidak dapat dipisahkan dari dunia pendidikan. Terdapatnya sistem informasi dan internet yang terus berkembang, maka diciptakan suatu cara penyampaian pendidikan secara elektronik dengan bantuan internet. Sistem informasi yang dimaksud pada saat sekarang lebih dikenal dengan istilah elektronik learning (e-learning). E-learning adalah suatu sistem informasi yang membantu pembelajaran manual menjadi pembelajaran secara elektronik. Pada dunia pendidikan untuk membantu dosen dan mahasiswa untuk memanajemen mata kuliah, saat sekarang ini terdapat Sistem Informasi Akademik yang lebih disingkat dengan SIA. SIA adalah suatu sistem informasi yang mengelola dan mengolah semua data-data akademik yang berada di bidang akademik. KRS online yang berada di SIA berhubungan erat dengan mata kuliah yang akan terisi pada e-learning. Dari pandangan kebutuhan tersebut, ada baiknya kedua sistem informasi tersebut digabungkan sehingga dengan user mengisi SIA, maka sistem e-learning yang berhubungan dengan mata kuliah yang diikuti akan terupdate dengan sendirinya dan perlu didesain sedemikian rupa agar kedua sistem informasi tersebut dapat berjalan dengan baik dan dapat digunakan oleh para user. Pendekatan ergonomis yang diperlukan untuk sistem tersebut adalah Human Computer Interaction (HCI) sehingga sistem yang dikembangkan akan nyaman, mudah dan aman digunakan oleh user atau dengan kata lain adalah user friendly. Jurnal ini disusun dengan tujuan untuk mengembangkan suatu sistem integrasi SIA dengan e-learning sehingga dapat membantu dan mempermudah aktifitas pembelajaran di Perguruan Tinggi.   ABSTRACT Growth of access to information at the present time is running fast. Public or the user to obtain data or information that is accurate, current, and a quick and easy right now is not difficult. The development of the Internet in today's increasingly rapidly and can not be separated from the world of education. Presence information systems and the Internet continues to grow, then created a way of delivering education electronically with the help of internet. The information system is at present better known as electronic learning (e-learning). E-learning is an information system that helps instructional manual to electronic learning. In the world of education to enable faculty and students to manage course, nowadays there are more Academic Information System shortened by SIA. SIA is an information system that manages and processes all the data of academic residing in the academic field. KRS SIA online that are closely related to the subjects that will be filled in e-learning. From the view of these needs, it helps both information systems are combined so that the user fills in SIA, the e-learning systems relating to subjects who follow will update itself and needs to be designed so that both the information system can run well and can used by the user. Ergonomic approach is needed for these systems is the Human Computer Interaction (HCI) so that the developed system will be convenient, easy and safe to use by the user, or in      other words is user friendly. These journals are intended to develop a system AIS integration with e-learning in order to assist and facilitate the activities of learning in Higher Education.

The explosion of information in the World Wide Web is overwhelming for readers with limitless information. Large internet articles or journals are often cumbersome to read as well as comprehend. More often than not, readers are immersed in a pool of information with limited time to assimilate all of the articles. As technology advances, it becomes more convenient to access information on-the-go, i.e., portability of information by utilizing mobile devices. In this research, a semantic and syntatic based summarization is implemented in a text summarizer to solve the information overload problem whilst providing a more coherent summary. The objective is to integrate WordNet into the proposed system aka TextSumIt which condenses lengthy documents into summarized text. The empirical experiments show that it produces satisfactory preliminary results on Android mobile phones.

QGIS is a free and open-source software that allows viewing, editing, and analyzing georeferenced data. It is a Geographic Information System (GIS) software composed by tools that allow to manipulate geographic information and consequently to create maps which help to get a better understanding and organization of geospatial data. Unfortunately, maps created directly in the GIS desktop software are not automatically transferred to a website. This research aimed to compare publishing capabilities in different QGIS plugins to create Web Maps. This study analyzes four QGIS plugins (QGIS2Web, QGIS Cloud, GIS Cloud Publisher and Mappia Publisher), performing a comparison between them, considering their advantages and disadvantages, the free and subscription plans, the tools offered by each plugin and other generic aspects. The four plugins were tested in a specific case study to automatically obtain different Web Maps. This study could help users to choose the most adequate tools to publish Web Maps under QGIS software.
