Web mapping services

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.

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.

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.

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...

Today, landscapes, cities, and infrastructure networks are commonly captured at regular intervals using LiDAR or image-based remote sensing technologies. The resulting point clouds, representing digital snapshots of the reality, are used for a growing number of applications, such as urban development, environmental monitoring, and disaster management. Multi-temporal point clouds, i.e., 4D point clouds, result from scanning the same site at different points in time and open up new ways to automate common geoinformation management workflows, e.g., updating and maintaining existing geodata such as models of terrain, infrastructure, building, and vegetation. However, existing GIS are often limited by processing strategies and storage capabilities that generally do not scale for massive point clouds containing several terabytes of data. We demonstrate and discuss techniques to manage, process, analyze, and provide large-scale, distributed 4D point clouds. All techniques have been implemented in a system that follows service-oriented design principles, thus, maximizing its interoperability and allowing for a seamless integration into existing workflows and systems. A modular service-oriented processing pipeline is presented that uses out-of-core and GPU-based processing approaches to efficiently handle massive 4D point clouds and to reduce processing times significantly. With respect to the provision of analysis results, we present web-based visualization techniques that apply real-time rendering algorithms and suitable interaction metaphors. Hence, users can explore, inspect, and analyze arbitrary large and dense point clouds. The approach is evaluated based on several real-world applications and datasets featuring different densities and characteristics. Results show that it enables the management, processing, analysis, and distribution of massive 4D point clouds as required by a growing number of applications and systems.

Transportation networks, such as streets, railroads or metro systems, constitute primary elements in cartography for reckoning and navigation. In recent years, they have become an increasingly important part of 3D virtual environments for the interactive analysis and communication of complex hierarchical information, for example in routing, logistics optimization, and disaster management. A variety of rendering techniques have been proposed that deal with integrating transportation networks within these environments, but have so far neglected the many challenges of an interactive design process to adapt their spatial and thematic granularity (i.e., level-of-detail and level-of-abstraction) according to a user's context. This paper presents an efficient real-time rendering technique for the view-dependent rendering of geometrically complex transportation networks within 3D virtual environments. Our technique is based on distance fields using deferred texturing that shifts the design process to the shading stage for real-time stylization. We demonstrate and discuss our approach by means of street networks using cartographic design principles for context-aware stylization, including view-dependent scaling for clutter reduction, contour-lining to provide figure-ground, handling of street crossings via shading-based blending, and task-dependent colorization. Finally, we present potential usage scenarios and applications together with a performance evaluation of our implementation.

Due to the advances in computer graphics and improved network speed it is now possible to navigate in 3D virtual world in real time. Until now, technologies employed require to install standalone application or plugins on navigators. The arrival of HTML 5 brings news solutions to visualize 3D data in a browser with WebGL. Several globe projects have proven that such technologies can be employed. Unfortunately, demonstrations are often based on proprietary formats to exchange or to store data. In this work, we propose to use CityGML: a standard provided by the Open Geospatial Consortium. CityGML files are imported in our Environment Editor. With several tools that we present in this paper, data are processed and stored. A client server application is also presented to permit the visualization of geometry and semantic in a navigator.

Prototype of vehicle Tracking Position Detection System uses ATmega328 Microcontroller-Based CSD Communication. This system is designed to detect the position of the vehicle wherever it is either the position of the vehicle at the time of abandonment or at the time of loss of the vehicle. The system consists of two sections, the first as object part and the second as navigation section, the object part is the integrated part in the form of GPS, Microncontroller ATmega328, and GSM SIM 800L module, the navigation section is the tracking part that includes the phone/computer. The system starts working When the communication between the GSM part of the object and the GSM part of the navigation will be connected in CSD (Circuit Switched Data), after connecting then the data location information recorded by the GPS receiver on the object section will be sent to the navigation section, the navigation section will perform positioning with map info based on the data sent by GSM's object

Digital Elevation Model (DEM) data are used for geological analysis when other data are not accessible for morphology and structure identification. DEM data due to its quick availability and less expense is used for enhancing accuracy. Three-dimensional (3D) inputs are added to the twodimensional (2D) data for a better interpretation of topography, relief, and geology. The present paper explicates the potential of DEM for modeling of Mikir structural hills of Assam-a highly dissected and geologically important region generated from Shuttle Radar Topography Mission (SRTM) and Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) images.

Energy is an essential factor of the economy, the national security of a nation as well as standard of living. Kenya's Vision 2030 identifies energy as one of the major enablers of infrastructure development under the socioeconomic pillar. Kenya is undergoing a rapid development stage in relation to its domestic energy demands. The current government demanded that Kenya Power and Lighting Company (KPLC) accelerate electricity connectivity within the country; this called for a totally new approach in the connectivity, meter reading and billing model within the electricity distribution company. Manual reading of power meters is indeed a time-consuming exercise, KPLC meter readers face a number of challenges while trying to gain access to customer postpaid meters in the field. These challenges range from unrestrained animals, inclement weather conditions, or meters located behind a locked fence and buildings. On the other hand, the company emergency teams also face a number of challenges while resolving power incidences reported by the customers. One of the main challenge includes locating the incident areas based on the vague description from the customers and hence lack of proper preparation (with the right equipment) to handle the reported incident. The growth in the telecommunication sector has enabled a positive willingness by power consumers to volunteer information and embrace new innovative approaches being implemented by the company. This study seeks to take advantage of this with the main objective of developing a complementary mobile and web-based application for recording and sharing electricity customer meter reading and power incidence data. The objective was achieved and the study was able to develop an electrical network geodatabase using Open Source software, PostgreSQL /PostGIS as the application database, a mobile application developed in Android studio using Java Programming Language, and a web application developed in the Node.JS environment using JavaScript. The application was published and tested within the case study area of Langata constituency in Nairobi County. The mobile application meter reading and power incidence reporting platform is aimed at improving customer billing process and timely resolution of incidences, ultimately customer satisfaction on service delivery. It is recommended that this application is replicated through all the other constituencies in Kenya to support meter reading and power outage management in the company. Other utility companies can use this application to efficiently improve service delivery to customers. These can range from water and sewerage companies, telecommunication companies to oil and gas distribution companies among others.

An efficient water management, not only allows significant savings in costs of irrigation, but also an effective control on the quality of products, which can have obvious consequences on income operation and reducing the environmental impact of irrigation. As the Internet is becoming the easiest way of information distribution, irrigation management system can also be benefitted with it. Integrating GIS functionality with internet capacity will redefine the way of decision making, sharing and processing of information. In irrigation systems weather plays an imperative role in decision making, implementing and forecasting. Temperature, humidity, precipitation, and solar radiation are the most important parameters to calculate evapotranspiration by which crop water requirement can be determined. SAGRA (Sistema Agrometeorológico para a Gestão da Rega no Alentejo) network is providing information to the farmers through web but still lacks the use of GIS in their information to decision support system. Irrigation management support system can be benefitted with the use of Web GIS. In this thesis, web based GIS is designed using popular open source tools and software. Using data from automatic weather station maps are produced using Geo-statistical interpolation techniques and published in web map. These maps can be viewed with popular online maps like Google maps, Microsoft Bing and Openstreet maps. Animated weather maps are also created which are useful for visualizing changing pattern of weather parameters and water requirement over time.

Mount Rotolon (Eastern Italian Alps) is affected by a complex landslide that, since 1985, is threatening the nearby village of Recoaro Terme. The first written proof of a landslide occurrence dated back to 1798. After the last re-activation on November 2010 (637 mm of intense rainfall recorded in the 12 days prior the event), a mass of approximately 320.000 m3 detached from the south flank of Mount Rotolon and evolved into a fast debris flow that ran for about 3 km along the stream bed. A real-time monitoring system was required to detect early indication of rapid movements, potentially saving lives and property. A web-based platform for automatic and continuous monitoring was designed as a first step in the implementation of an early-warning system. Measurements collected by the automated geotechnical and topographic instrumentation, deployed over the landslide body, are gathered in a central box station. After the calibration process, they are transmitted by web services on a local server, where graphs, maps, reports and alert announcement are automatically generated and updated. All the processed information are available by web browser with different access rights. The web environment provides the following advantages: 1) data is collected from different data sources and matched on a single server-side frame 2) a remote user-interface allows regular technical maintenance and direct access to the instruments 3) data management system is synchronized and automatically tested 4) a graphical user interface on browser provides a user-friendly tool for decision-makers to interact with a system continuously updated. On this site two monitoring systems are actually on course: 1) GB-InSAR radar interferometer (University of Florence-Department of Earth Science) and 2) Automated Total Station (ATS) combined with extensometers network in a Web-based solution (CNR-IRPI Padova). This work deals with details on methodology, services and techniques adopted for the second monitoring solution. The activity directly interfaces with local Civil Protection agency, Regional Geological Service and local authorities with integrated roles and aims.

Three-dimensional (3D) inputs are added to the twodimensional (2D) data for a better interpretation of topography, relief, and geology. The present paper explicates the potential of DEM for modeling of Mikir structural hills of Assam-a highly dissected and geologically important region generated from Shuttle Radar Topography Mission (SRTM) and Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) images.

Telemetry, Tracking, and Command (TT&C) is part of the satellite subsystem that functions as a communication link between satellites and ground stations. The TT&C systems provide the uplink for command, downlink for monitoring parameters through telemetry and is needed for monitoring satellite position in orbit. In LAPAN ground station, the TT&C configuration uses one UHF transceiver radio unit, and one modem for each satellite of LAPAN A2 and LAPAN A3. To simplify the need for LAPAN ground station, a switch module is required that can combine two modems with one transceiver radio unit, without reducing quality of signal from radio to modem. This paper describes the results of design, and testing of the switch module. The modem switch module uses ATmel microcontroller with IC 4053 multiplexer as main component. Meanwhile, software implemented on microcontroller uses basic compiler language, with RS-232 serial interface, and Visual studio as GUI interface. The design of modem switch ...

Many Information Technology (IT) tools play a vital role in the business world due to their wider applicability. Extremely competitive retail environment necessitates retailers to choose new store locations strategically. GIS with its capability to manage, display and analyze business information spatially, is emerging as one of the powerful location intelligence IT tool. The purpose of this paper is to explore the possibility of strategic retail outlet location through online Decision Support System (DSS) in Hyderabad Metropolitan city, India. The procedure makes use of data, information and software from Web-based Geographical Information Systems (GIS) to generate online analysis, mapping and visualization systems. These procedures are integrated and synchronized with appropriate data layers (multi data layer system) to arrive at better decisions. This DSS combines different data layers through spatial methodological analysis to arrive at possible solution for ideal retail store location.

We present the results of a comparative study among four well-known web mapping services. The study explored how digital natives (young people under 30 years old who were born and raised with technology and smart devices) interact with web mapping services. The sample consisted of 167 University students in the field of Engineering and was conducted entirely online. Results indicate that the nature of tasks performed using mapping services affect both effectiveness and efficiency even when users interact with the same service. Among services, study results also indicate differences between task success rates as well as between successful task completion times. Finally, comparison between male and female participants showed no difference in either effectiveness or efficiency between genders.
