“…The IoT leads to networks connecting billions of real-time interacting and communicating things, creating huge ICT systems that expand in a great variety of administrative domains. Another more recent example is the appearance of the vision of connecting the IoT to Earth Observation (EO) systems and the geospatially enabled web as investigated in [5].…”

Attempts to facilitate and streamline systems architecting have resulted in a great number of reusable principles, practices, mechanisms, frameworks, and tools. Such a practice is the use of architectural viewpoints and views. However, as systems change, these practices should also evolve. The increasing scale and complexity of systems resulting from an ever-growing pool of human needs and breakthroughs may lead, in some cases, to an increased gap between the abstraction activities attempting to capture the whole of a system, and the instantiation activities that produce concrete and detailed descriptions of a system’s architecture. To address this issue, this article introduces a new notion, that of architectural glimpse statements, fundamental questions acting as the building blocks for architectural views and products. This notion can help architects ask the right questions in the right manner to create fundamental statements, the elaboration on which can lead directly to concrete architectural products. Working on top of standardized and common approaches, the article introduces a language for the creation of architectural glimpse statements using the 5W1H maxim. Based on this language, a tool and guidelines are also provided to facilitate the usage of glimpses. Finally, the overall methodology is demonstrated in two case studies.

“…Server-client WMS communication uses the World Wide Web (WWW) standard protocol, which is based on HTTP where the client sends requests in Uniform Resource Locators (URLs) containing standard parameters of the detailed operations requested using POST or GET methods [2]. WMTS is an alternative type of WMS that uses the tiling model that makes it easier to generate images in PNG or JPEG formats using previous requests [3]. WMTS response is faster than WMS because WMTS loads one data and data tiling virtually [4] and minimizes the cost of computing to increase computation performance [5].…”

SPACeMAP is a remote-sensing data portal system owned by LAPAN used to distribute mosaic data of Medium-Resolution to Very-High-Resolution for Provincial Governments. The frequently arising problem is that mosaic images have very large data size, especially for SPOT-6/7 mosaic images. The increasing number of data and users may affect the data loading process on the portal so that mosaic data compression can be considered. SPACeMAP has the Image Compressor feature using the Tile and Line algorithms with a compression ratio (target rate) recommended for optics (15 to 20). This study aims to determine the best algorithm and target rate to get compressed mosaic SPOT-6/7 imagery. The comparison method was done qualitatively through visual comparison and quantitatively by using Compression Ratio (CR), Bit per Pixel (BPP), and Peak Signal to Noise Ratio (PSNR). Results of the experiment show that, quantitatively, both Tile and Line algorithms give a different performance, depends on the zoom level and land cover characteristics. In terms of the qualitative result, the Tile algorithm gives better overall results compare to the Line algorithm. Quantitatively, both algorithms show good performance in the homogenous area. The target rate difference on the testing range does not affect process duration, nevertheless, the Line algorithm has a long process duration compare to the Tile algorithm. However, compression mosaics with lower or higher resolution remote sensing data may provide different results. Hence, this need be addressed on further studies.

“…In fact, the SensorThings API is specifically designed for resource-constrained IoT devices. These standardized interfaces permit the proliferation of new high-value services with decreased development overhead, wider reach, ease of sharing, and lower cost for sensor and gateway providers [2][3][4].…”
