“…Web GIS development uses several open-source components, such as Map-Server and Pmapper (Burger 2009). The open-source software model adjusts the purpose of making the system by defining layers and control layers (Gkatzoflias et al 2013, Thiebes et al 2013, Nakayama et al 2017. The layer in Pmapper Anang Wahyu SEJATI, Imam BUCHORI, Iwan RUDIARTO, Christopher SILVER, Kartiko SULISTYO controls the attributes and the digital maps that appear in Web GIS.…”

“…The concept of Web GIS is the ability to provide an overview of spatial information with spatial data that provides information to support decision making (Thiebes et al 2013, Buchori et al 2015b, Sejati and Ramadhan 2015. For developing countries, Web GIS can be produced by exploiting open-source softwares, so that the cost is cheaper, and the purpose of open data especially in delivering public policy can be achieved (Nakayama et al 2017).…”

This paper presents a Web GIS application development framework through an open-source software which aims to provide reliable open data services, required for policymaking in urban land use planning. The geodatabase model is comprehensively developed. It displayed a user interface using QGIS, MapServer, and Pmapper, with open source tools with PHP MapScript programming languages and integrated DB-SQL, to generate a complete digital map service with information on urban land use policy. The results of this Web GIS development can be publicly used with spatial databases suitable for public consumption, and as decision support systems for stakeholders, especially in the policy of urban land use planning. Thus, this application can serve as a model for land-use monitoring systems based upon the principle of information disclosure toward smart city and smart governance.

“…One of the addressed problems was the restricted display resolution and the sensitivity of the user interface for touch events. Nakayama et al developed a web GIS framework for participatory sensing using mobile devices [26]. The developed prototype is based on Drupal and focuses on nonprofessional users.…”

There are multiple location-based services (LBSs) and mobile GIS available for a wide range of applications. Usually such applications are developed to solve a restricted task within a restricted environment. The focus on a particular task is strong, and therefore, such applications can usually not be used in multiple environments. To overcome this issue, this paper presents a concept of a generic professional mobile GIS with a focus on interoperability. Firstly, common issues of mobile applications are presented, and their impact on the development of mobile GIS is analyzed. Subsequently, a new approach for a generic mobile GIS for professional users is presented. Based on multiple OGC standards, the approach leads to a system that can be used in various applications where the quality of surveyed data and analysis capabilities are improved. To prove the strength of the approach with GeoTechMobile, a prototype is presented and evaluated in a case study.

“…Similarly, a levee project information management system is developed (Zhang et al, 2018) based on WebGIS for flood prevention and decision management in levee projects. Furthermore, a general WebGIS framework is proposed (Nakayama et al, 2017) for the collection and management of spatial data. In the field of environmental sciences, modern web technologies, cloud and storage systems is presented (Vitolo et al, 2015;Seo et al, 2019) to address the issues in the modeling and handling multidimensional raster images.…”

Geographic Information Systems (GIS) are available as stand-alone desktop applications as well as web platforms for vector- and raster-based geospatial data processing and visualization. While each approach offers certain advantages, limitations exist that motivate the development of hybrid systems that will increase the productivity of users for performing interactive data analytics using multidimensional gridded data. Web-based applications are platform-independent, however, require the internet to communicate with servers for data management and processing which raises issues for performance, data integrity, handling, and transfer of massive multidimensional raster data. On the other hand, stand-alone desktop applications can usually function without relying on the internet, however, they are platform-dependent, making distribution and maintenance of these systems difficult. This paper presents RasterJS, a hybrid client-side web library for geospatial data processing that is built on the Progressive Web Application (PWA) architecture to operate seamlessly in both Online and Offline modes. A packaged version of this system is also presented with the help of Web Bundles API for offline access and distribution. RasterJS entails the use of latest web technologies that are supported by modern web browsers, including Service Workers API, Cache API, IndexedDB API, Notifications API, Push API, and Web Workers API, in order to bring geospatial analytics capabilities to large-scale raster data for client-side processing. Each of these technologies acts as a component in the RasterJS to collectively provide a similar experience to users in both Online and Offline modes in terms of performing geospatial analysis activities such as flow direction calculation with hydro-conditioning, raindrop flow tracking, and watershed delineation. A large-scale case study is included in the study for watershed analysis to demonstrate the capabilities and limitations of the library. The framework further presents the potential to be utilized for other use cases that rely on raster processing, including land use, agriculture, soil erosion, transportation, and population studies.
