Visualizations are important for understanding coastal landscape evolution and its driving processes. Visualizing change in highly dynamic coastal terrain poses a formidable challenge; the combination of natural and anthropogenic forces leads to cycles of retreat and recovery and complex morphology of landforms. In recent years, repeated high-resolution laser terrain scans have generated a time series of point cloud data that represent landscapes at snapshots in time, including the impacts of major storms. In this article, we build on existing approaches for visualizing spatial\u2013temporal data to create a collection of perceptual visualizations to support coastal terrain evolution analysis. We extract terrain features and track their migration; we derive temporal summary maps and heat graphs that quantify the pattern of elevation change and sediment redistribution and use the space\u2013time cube concept to create visualizations of terrain evolution. The space\u2013time cube approach allows us to represent shoreline evolution as an isosurface extracted from a voxel model created by stacking time series of digital elevation models. We illustrate our approach on a series of Light Detection and Ranging surveys of sandy North Carolina barrier islands. Our results reveal terrain changes of shoreline and dune ridge migration, dune breaches and overwash, the formation of new dune ridges, and the construction and destruction of homes, changes which are due to erosion and accretion, hurricanes, and human activities. These events are all visualized within their geographic and temporal contexts. <\/jats:p>","DOI":"10.1177\/1473871613487086","type":"journal-article","created":{"date-parts":[[2013,5,23]],"date-time":"2013-05-23T02:06:59Z","timestamp":1369274819000},"page":"266-282","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":13,"title":["Visualizations of coastal terrain time series"],"prefix":"10.1177","volume":"13","author":[{"given":"Laura","family":"Tateosian","sequence":"first","affiliation":[{"name":"North Carolina State University, Raleigh, NC, USA"}]},{"given":"Helena","family":"Mitasova","sequence":"additional","affiliation":[{"name":"North Carolina State University, Raleigh, NC, USA"}]},{"given":"Sidharth","family":"Thakur","sequence":"additional","affiliation":[{"name":"Renaissance Computing Institute, Chapel Hill, NC, USA"}]},{"given":"Eric","family":"Hardin","sequence":"additional","affiliation":[{"name":"North Carolina State University, Raleigh, NC, USA"}]},{"given":"Emily","family":"Russ","sequence":"additional","affiliation":[{"name":"North Carolina State University, Raleigh, NC, USA"}]},{"given":"Bruce","family":"Blundell","sequence":"additional","affiliation":[{"name":"US Army, Alexandria, VA, USA"}]}],"member":"179","published-online":{"date-parts":[[2013,5,22]]},"reference":[{"key":"bibr1-1473871613487086","doi-asserted-by":"publisher","DOI":"10.2112\/05-0583.1"},{"key":"bibr2-1473871613487086","doi-asserted-by":"publisher","DOI":"10.1016\/j.geomorph.2005.06.001"},{"key":"bibr3-1473871613487086","doi-asserted-by":"publisher","DOI":"10.1016\/S0034-4257(02)00185-2"},{"key":"bibr4-1473871613487086","doi-asserted-by":"publisher","DOI":"10.2112\/07-0985.1"},{"key":"bibr5-1473871613487086","doi-asserted-by":"publisher","DOI":"10.1016\/j.compenvurbsys.2010.05.002"},{"key":"bibr6-1473871613487086","doi-asserted-by":"publisher","DOI":"10.1080\/13658816.2010.508043"},{"key":"bibr7-1473871613487086","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvlc.2011.04.001"},{"key":"bibr8-1473871613487086","first-page":"276","volume-title":"RIVF 2008: IEEE international conference on research, innovation and vision for the future, 2008","author":"Ho Q"},{"key":"bibr9-1473871613487086","volume-title":"Proceedings of the workshop on the intersections between geospatial information and information technology","author":"Pang A"},{"key":"bibr10-1473871613487086","first-page":"3","volume-title":"Geomorphometry 2011","author":"Mitasova H"},{"key":"bibr11-1473871613487086","doi-asserted-by":"publisher","DOI":"10.1111\/j.1435-5597.1970.tb01464.x"},{"key":"bibr12-1473871613487086","first-page":"1988","volume-title":"Proceedings of 21st international cartographic conference","author":"Kraak M"},{"key":"bibr13-1473871613487086","doi-asserted-by":"publisher","DOI":"10.1109\/TVCG.2008.194"},{"key":"bibr14-1473871613487086","doi-asserted-by":"crossref","first-page":"48","DOI":"10.1093\/oso\/9780195152708.003.0003","volume-title":"Spatially integrated social science","author":"Kwan MP","year":"2004"},{"key":"bibr15-1473871613487086","volume-title":"XXII international cartographic conference","author":"Shrinivasan Y"},{"key":"bibr16-1473871613487086","first-page":"145","volume-title":"IV 2004 proceedings: eighth international conference on information visualisation 2004","author":"Gatalsky P"},{"key":"bibr17-1473871613487086","doi-asserted-by":"publisher","DOI":"10.1559\/152304009788988297"},{"key":"bibr18-1473871613487086","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-03521-0_8"},{"key":"bibr19-1473871613487086","first-page":"199","volume-title":"ISPRS STM 2005: proceedings of the international symposium on spatio-temporal modeling, spatial reasoning, analysis, data mining and fusion","author":"Li X"},{"key":"bibr20-1473871613487086","doi-asserted-by":"publisher","DOI":"10.1615\/Int.J.UncertaintyQuantification.2012003969"},{"key":"bibr21-1473871613487086","unstructured":"N.C.S.
