Interactive Visual Exploration and Analysis of Multi-Modal Geospatial Data Collections

Abstract

This thesis presents PanoVis, a geovisualization web application for hikers looking for online hiking inspiration. Hikers can add panoramic imagery to the application, and annotations with information about the mountain peaks visible are added to the panoramas using a combination of manual and automatic techniques. A set of visual components automatically update to reflect the image in view, and hikers can explore multiple images through different interaction methods. These visual components include visualizations of an image location's nearby terrain in two and three dimensions. The thesis discusses various aspects concerning the development of PanoVis, including its design, implementation, and how we evaluate its functions.
