Owgis 2.0

Abstract

OWGIS version 2.0 is an open source Java and JavaScript application that builds easily configurable Web GIS sites for desktop and mobile devices. This version of OWGIS generates mobile interfaces based on HTML5 technology and can be used to create mobile applications. The style of the generated websites is modified using COMPASS, a well known CSS Authoring Framework. In addition, OWGIS uses several Open Geospatial Consortium standards to request data from the most common map servers, such as GeoServer. It is also able to request data from ncWMS servers allowing the display of 4D data from NetCDF files. This application is configured by XML files that define which layers, geographic datasets, are displayed on the Web GIS sites. Among other features, OWGIS allows for animations; vertical profiles and vertical transects; different color palettes; dynamic maps; the ability to download data, and display text in multiple languages. OWGIS users are mainly scientists in the oceanography, meteorology and climate fields.

Intelligent geovisualizations for open government data (vision paper)

“…The SIGSPATIAL community has done some work on automatic generation of road networks from GPS traces (see e.g., [10,13]), which addresses one specific type of geovisualization (i.e., network), and might inform future approaches that automatically produce more complex geovisualizations (e.g., interactive maps and timelines). Zavala-Romero et al's work on generating web GIS without programming knowledge [44] is in line with the idea outlined here, but only implements a small subset of it (i.e., their tool automatically builds web GIS interfaces to visualize NetCDF data). Existing work on map labelling (e.g., [5,27]), or computing aggregation of large point datasets [6] is also relevant in this context.…”
