Abstract
Several real-world applications involve the aggregation of physical features corresponding to different geographic and topographic phenomena. This information plays a crucial role in analyzing and predicting several events. The application areas, which often require a real-time analysis, include traffic flow, forest cover, disease monitoring and so on. Thus, most of the existing systems portray some limitations at various levels of processing and implementation. Some of the most commonly observed factors involve lack of reliability, scalability and exceeding computational costs. In this paper, we address different well-known scalable serverless frameworks i.e., Amazon Web Services (AWS) Lambda, Google Cloud Functions and Microsoft Azure Functions for the management of geospatial big data. We discuss some of the existing approaches that are popularly used in analyzing geospatial big data and indicate their limitations. We report the applicability of our proposed framework in context of Cloud Geographic Information System (GIS) platform. An account of some state-of-the-art technologies and tools relevant to our problem domain are discussed. We also visualize performance of the proposed framework in terms of reliability, scalability, speed and security parameters. Furthermore, we present the map overlay analysis, point-cluster analysis, the generated heatmap and clustering analysis. Some relevant statistical plots are also visualized. In this paper, we consider two application case-studies. The first case study was explored using the Mineral Resources Data System (MRDS) dataset, which refers to worldwide density of mineral resources in a country-wise fashion. The second case study was performed using the Fairfax Forecast Households dataset, which signifies the parcel-level household prediction for 30 consecutive years. The proposed model integrates a serverless framework to reduce timing constraints and it also improves the performance associated to geospatial data processing for high-dimensional hyperspectral data.
Highlights
Recent years have witnessed enormous growth in the production of massive digital data, which has facilitated the perception and cognition of several features from the physical world
We proposed a framework for geospatial applications to run over a serverless computing paradigm
The problem with geospatial applications is that it uses specific tools to execute like QGIS, ArcGIS and others
Summary
Recent years have witnessed enormous growth in the production of massive digital data, which has facilitated the perception and cognition of several features from the physical world. Several studies have focused on the efficacy achieved by implementing distributed computing platforms for geospatial information querying, processing and sharing [20,21,22]. This framework was observed to overcome most of the challenges associated with local computing resources and databases by advantageously facilitating the collection and distribution of heterogeneous geospatial data. It can aid the rendering of a computationally dynamic framework for the logical sharing of the computing resources on a global scale This essentially solves the complex geospatial data processing associated challenges. In order to facilitate improved delivery of services, different distinct classes namely, mobile computing, fog computing and edge computing frameworks came into existence [22,23,24,25]
