“…The first technique implemented is a traditional raster model, using textures for displaying raster images. While traditional raster handling is fast and adequate for rectangular rasters, it imposes serious limitations on the underlying data (Bugya & Farkas, ). Apart from the advantages of using vector cells in the representation model, the coverage model has one clear advantage.…”

Transactions in GIS. 2020;24:72-84. wileyonlinelibrary.com/journal/tgis | INTRODUC TI ONRapid development of technology in recent decades has not only introduced new possibilities in GIS and cartography, but also transformed them. The main focus has shifted from traditional mapping and analysis of spatial data to new, digitally better-supported approaches. For example, experts can now produce three-dimensional models from digital images, have to deal with different types of big data, and are finding ways to apply machine learning to Abstract Companies and individual developers have recently put serious effort into improving web mapping libraries. A significant front in this development is hardware-accelerated vector graphics. Owing to those efforts, and the continuously evolving World Wide Web, users can visualize large vector layers, and even animate them. On the other hand, this rapid development cannot be observed with raster data. There are some data abstraction libraries for reading raster files, although web mapping libraries do not use them to offer raster capabilities. Since there are no mature raster management pipelines on the web, this study explores two inherently different techniques for handling raster data.One of them uses the traditional, texture-based method.The other is a hybrid technique rendering raster layers as vectors, overcoming some limitations of the raster model.While the traditional technique gives a smooth user experience, the hybrid method shows promising results for rendering hexagonal coverages.

“…The other technique implemented is visualizing rasters as vectors, which has been named the coverage model (Bugya & Farkas, ). Coverages have the same data structure; they store raw data in matrices, and other attributes in bands.…”

Infrastructure management is an integral part of management in Universiti Kebangsaan Malaysia (UKM). One of the important infrastructures is the power distribution network system. Integration of Geographical Information System (GIS) in the power distribution system provides an upgrade in method to collect, store, and handle the data more professionally. Web-GIS application platform allows online data sharing for authorizing the users to get access to spatial and non-spatial data of the power system. Interactive online mapping provides three important modules that are viewing the module, statistical module and query module. These three proposed module is to help the user become more understanding of the related data. This paper describes how the process starting from data collection until the production of Web-GIS for online data sharing in the electrical distribution network system in UKM. The proposed online application integrates all the spatial data with complete power distribution information. This Geospatial system is able to enhance the management quality for a better sustainable campus.
