La prima edizione della Carta stradale automobilistica d'Italia, 1:250.000, costruita da Achille Dardano e Giovanni De Agostini (Istituto geografico De Agostini) per conto del Touring Club Italiano, ha un secolo. La prima "puntata" vide la luce nel 1906, modificando radicalmente sia la percezione del territorio italiano (e non solo dal punto di vista turistico), sia la fruibilità dello strumento cartografico da parte di un pubblico non specialistico e non avvezzo alla cartografia topografica. Operazione di grandissima qualità tecnica e artistica, costruita e edatta dal maestro riconoscito della cartografia italiana contemporanea, questa carta ha anche avuto il grande merito di costituire la più grande raccolta di toponimi italiani (grazie all'indice cumulativo dei fogli).

In order to connect, in a digital format, two maps with different coordinate reference systems we developed a mixed methodology (manual and automated). As an instance, we transformed a yugoslavian map (Crs: D48) into a Italian reference system (Crs: Gauss-Boaga, East zone). The study area is the Gorizia and Nova Gorica borderscape, already analysed by the “Gorizia Nova Model Plan” Interreg Project. The proposed method gives a better result (in terms of the measured positional errors) with respect to the main Gis application automated transformation procedures available in the market. Nevertheless the same has some limitations connected to the application of the model to other areas without updating some parameters.

In the today's world, security is required to transmit confidential information over the network. Security is also demanding in wide range of applications. Cryptographic algorithms play a vital role in providing the data security against malicious attacks. Encryption of data is an important topic for research, as secure and efficient algorithms are needed that allow optimized encryption and decryption of data. In this paper we propose a new encryption algorithm, called Reverse Encryption Algorithm (REA). Our new encryption algorithm (REA) is simple and fast enough for most applications. REA encryption algorithm provides maximum security and limits the added time cost for encryption and decryption.

Web Services technology has the potential to cater an enterprise's needs, providing the ability to integrate different systems and application types regardless of their platform, operating system, programming language, or location. Web Services could be deployed in traditional, centralized or brokered client server approach or they could be in peer to peer manner. Web Services could act as a server providing functionality to a requester or act as a client, receiving functionality from any service. From the performance perspective the availability of Web Services plays an important role among many parameters.

methodological tool to improve the territorial planning and management process of the airport surrounding areas. The works have consisted on the development of an Expert System prototype tested on a 5 km area influence from the airport of Palma (Mallorca, Spain). From a territorial database, a deep space analysis has been developed in relation to the behavior of the different variables, and their distribution patterns as well as their relationships. Consequently, multicriteria models have been implemented in order to create a set of decision rules which will allow to identify the suitable uses and adapt to its territorial characteristics. The user interface has been implemented in a Web-based technology, which has a Cartographic Server built over the Internet GIS software: ArcIMS (ESRI) that fulfills the standards OpenGIS Consortium and facilitates the user the remote access to the system and the cartographic information. It can be used at

Security being the major concern during data transfers, we have various challenges to face. The requirements of the security model vary depending on the type of data to be encrypted. Considering small size of data the requirements change from the existing security encryption techniques. One of the major issues to be considered is the computational speed of the encryption model. Though there are many challenging encryption algorithms, which provide high level of security, they increase the level of execution time for encryption. Cost effectiveness of the encryption algorithm is also another main concern for determining the efficiency of the algorithm. The computational time of the algorithms have a major impact on the determining the cost effectiveness. In this paper, we propose an enhanced cost effective symmetric key algorithm for small amount of data.

Security of data is the challenging aspects of modern information technology. An improved cryptology algorithm is introduced in this paper to offer comparatively higher security. We divide our message into several blocks as 8bits per block then convert each character into its corresponding positional number, where uppercase letters, lowercase letters, digits and special characters are mapped into some range of numbers. Then replace each decimal number into their binary equivalent consisting of 7-bits. Then combine 8 blocks of binary numbers into a single string. After performing some operation on the data, we get the final encrypted message. For decryption, we use same method in reverse way. Taking the decrypted message we perform some basic operation as replacing by binary or equivalent decimal and position then we get the original message back. Though the length of the encrypted message is larger than original message in this proposed algorithm, it offers higher security for the r...

The code in this replication package constructs the analysis file from four main data sources (2009 DPD AVL Data, 2009 DPD 911 Call Data (sde_call2009.dta), 2009 DPD Arrest Data (sde_arre), 2009 DPD Crime Data (sde_crim.dta)) using PostgreSQL (together with QGIS) and Stata. There are 8 files run in PostgreSQL to create the geographic mappings that capture the number of police officers in the vicinity of 911 calls. After these steps are taken, one main master file in Stata calls all of the files necessary to generate the data for the 7 figures and 8 tables in the paper & one main master_appendix file in Stata creates the 5 figures and 9 tables in the online appendix. The replicator should expect the code to run for about 90 hours (or more dependent on their computer abilities).

This research aims to develop a system to monitor moving objects via web. The moving objects could be owned by individuals or company and can be used and managed independently. The system consists of three subsystems namely Mobile Geographical Location Sender (MGLS), Main Geographical Location Information Control (MGLIC), and Geographical Location Information User (GLIU). MGLS functions as geographical sensor. It retrieves GPS data and sends periodically to MGLIC as the main controller via 3G service. MGLIC is the receiving server and designed as web server as well. The web server is the host of a control application that processes GPS data that was sent by MGLS. The data is stored in a database and is centrally displayed. The processed information can also be used by GLIU, as another user that needs the information. Experimental test shows that the system can function according to the design.

We present the design and implementation of an empirical synchronous remote study for exploring the relation between spatial ability and performance on webmapping services involving undergraduate University students; digital natives. The study exploits Spatial Thinking Ability Test to assess participants' spatial ability and to reveal if and to what extent it is related to their ability to perform tasks on popular web-mapping services. Participants' performance was assessed on the basis (a) of successfully executing tasks and (b) of how much time participants needed to properly perform tasks. A usability scale was used to measure participants' subjective perceptions of web-mapping services usability. Moreover, participants were self-assessed in digital skills using the Digital Natives Assessment Scale. Results reveal differences among services in task accuracy indicating that not only the web-mapping service but also the nature of tasks guide participants' performance. Correlations between spatial ability, digital skills, system usability, familiarity, and performance using web mapping services tend to be low and not significant leading to the assumption that success when interacting with a web mapping service is underlined by other factors as well.

Web mapping and the use of geospatial information online have evolved rapidly over the past few decades. Almost everyone in the world uses mapping information, whether or not one realizes it. Almost every mobile phone now has location services and every event and object on the earth has a location. The use of this geospatial location data has expanded rapidly, thanks to the development of the Internet. Huge volumes of geospatial data are available and daily being captured online, and are used in web applications and maps for viewing, analysis, modeling and simulation. This paper reviews the developments of web mapping from the first static online map images to the current highly interactive, multi-sourced web mapping services that have been increasingly moved to cloud computing platforms. The whole environment of web mapping captures the integration and interaction between three components found online, namely, geospatial information, people and functionality. In this paper, the trends and interactions among these components are identified and reviewed in relation to the technology developments. The review then concludes by exploring some of the opportunities and directions.

Over the past year, members of the Institute of Geomatics Engineering (IVGI) at the University of Applied Sciences and Arts Northwestern Switzerland (FHNW) have developed the "IVGI Noise App", an application to map and view noise level data. The web application is for use in environmental education during events, promoting science and engineering at secondary schools. The idea is to raise awareness of noise pollution and its consequences among students, while fostering their interest in spatial technologies by highlighting their role and potential in real-world problem solving.

ABSTRACT
The study on the design and implementation of cryptographic data security for IoT devices using Unicode and ASCII is motivated by the high rate of insecurity of data observed during data transfers on IoT devices. IoT devices are one of the popular channels that assist users to communicate virtually from the comfort of their homes. Therefore, the purpose of this study is to design software for cryptographic data security that can encrypt data while in transit to another IoT device using a cipher algorithm based on symmetric encryption. Some related encryption algorithms were also reviewed. In gathering data, secondary sources were deployed for useful information. The waterfall development methodology was utilized in this work. It is a methodology where phases do not overlap and the input of the current phase is the output of the previous phase. The use of Unicode and ASCII in substitution and transposition techniques helped to achieve confidentiality, authentication, integrity, and guaranteed data security. The system was implemented using the PHP programming language, HTML, and CSS. The results obtained from this research indicate that the software outperforms other conventional encryption algorithms in terms of speed (it encrypted 148 kb of data in 0.00267 MS) and also in terms of cryptanalyst attacks such as brute-force and dictionary attacks. The software is highly recommended to individual users, network administrators, medical centers, educational institutions, and government organizations.

The idea behind the Infrastructure for Spatial Information in Europe (INSPIRE) project was to provide EU citizens with access to various types of information, including environmental protection and spatial management data. These resources can be viewed (Web Map Service—WMS) and downloaded (Web Feature Service—WFS) online. Cadastral datasets represent one of the 34 spatial data themes in the spatial data infrastructure (SDI). The functionality of the SDI has not yet been fully achieved due to the failure of the WMS and WFS network services. The aim of this article was to assess the completeness of the SDI containing cadastral datasets. The present study has practical implications. The proposed diagnostic tool supports an assessment of the completeness of SDI resources in seven diagnostic groups (technical and legal identifiers, the cadastral information profile, the WMS network service, the WFS network service, source cadastral databases, data validity, and WMS and WFS standardizatio...

Skripsi ini membahas tentang perancangan dan implementasi program converter untuk sebuah sistem penerbangan yang sedang dikembangkan oleh BPPT (Badan Pengkajian dan Penerapan Teknologi). Tujuan dari skripsi ini adalah untuk membantu pengujian sistem ADS-B (Air Dependent Surveillance Broadcast) yang berada di BPPT. Metode yang digunakan oleh penulis adalah metode analisis yang dilakukan dengan 3 cara yaitu mencari referensi literatur yang berkaitan dengan hal-hal yang akan dikaji, melakukan wawancara dengan dosen pembimbing, dan meninjau langsung sistem ADS-B yang sedang berjalan di BPPT. Selain metode analisis, penulis juga menggunakan metode perancangan program dimana penulis menggunakan bahasa pemrograman C++ dan konsep pemrograman berorientasi objek. Analisis yang didapat oleh penulis adalah ADS-B receiver yang berada di BPPT memiliki format data ASTERIX-21 versi 0.26 dan mengirimkan data secara unicast ke ADP (ADS-B Data Processor). Sementara kondisi yang diharapkan adalah ADS-B receiver dapat mengirimkan format data ASTERIX-21 versi 0.23 secara multicast ke ADP. Untuk itu, perlu dibuat sebuah program yang akan ditempatkan diantara ADS-B receiver dan ADP dimana program tersebut berfungsi untuk menerima format data ASTERIX-21 versi 0.26 secara unicast dari ADS-B dan kemudian mengirimkan kembali data tersebut ke ADP dengan format data ASTERIX-21 versi 0.23 secara multicast. Hasil dari penelitian ini adalah HMI (Human Machine Interface) dapat menampilkan informasi dari setiap pesawat yang mengirimkan datanya ke ADS-B receiver dan dapat disimpulkan bahwa program telah berhasil merubah format data ASTERIX-21 versi 0.26 menjadiversi 0.23.

In a Grid Computing scenario, where the market players are dynamic; traditional assumptions for establishing and evaluating trust, do not hold good anymore. There are two different methods for handling access controls to the resources in grids: first by using policy based approach; where logical rules and verifiable properties are encoded in signed credentials and second by using reputation based approach; where trust values are collected, aggregated and evaluated to disseminate reputation among the market players. There is a need for dynamic and flexible general-purpose trust management system. In this paper TUX-TMS: an extensible reputation based Trust Management System is presented for establishing and evaluating trust in grid systems.

Composition of web services has emerged as a fast growing field of research since an atomic service in its entirety is not capable to perform a specific task. Composition of web services is a process where a set of web services, heterogeneous in nature, are clubbed together in order to perform a specific task. Individually, Component web services may be performing well as far as Quality of Service (QoS) is concerned but the core issue is that while composing, do they satisfy Users requirements in terms of QoS? Computation of QoS while composing web services appears to be a big challenge. A lot of research work in this regard, has already been undertaken to come out with new, innovative and credible solutions for the same. This Paper presents a thorough review-study of different frameworks, architectures, methodologies and algorithms suggested by different researchers in their efforts to compute the overall QoS while composing web services. Moreover, Effectiveness of different methods in terms of QoS while composing is also presented.
