Report on Component 2 - Designing New Methods for Visualizing Text in Spatial Contexts
Abstract
Component 1 performed a broad review of existing visualization approaches to depicting qualitative spatial data, particularly that derived from text sources. These included both representation methods as well as interaction types that have had demonstrated utility in tasks that require the visualization of textual media that may originate from a variety of sources and may include a focus on the structure of documents, their relationships, and their associated entities. Using the understanding obtained during work on Component 1, and follow up consultation with USACE, we designed new methods that can be used to provide text information integrated with interactive maps. As previously discussed, we have focused our effort on two types of visualization integration: (a) representations that are overlaid on the map itself and (b) coordinated view approaches that offer interactive, visual coupling between separate text and map visualizations. SensePlace2 - an in-house geovisual analytics tool - was chosen as the testing platform for our design ideas, which were implemented as extensions and modules that fit into the original SensePlace2 data processing and visualization pipeline. This report outlines the key capabilities of the modules that were added to SensePlace2 as part of work on Component 2 and provides a detailed description of each of the major visualization components.
