Introduction

Hardin, Eric; Mitasova, Helena; Tateosian, Laura; Overton, Margery

Pages: 1 –6

[Management of highly dynamic coastal landscapes requires repeated mapping and analysis of observed changes. Modern remote sensing techniques, such as lidar, increased the frequency and level of detail in coastal surveys and new methods were developed to extract valuable information from these...

Processing Coastal Lidar Time Series

Hardin, Eric; Mitasova, Helena; Tateosian, Laura; Overton, Margery

Pages: 7 –25

[In this chapter, we analyze time series of lidar data point clouds to assess the point density, gaps in coverage, spatial extent and accuracy. Based on this analysis and a given application we select appropriate resolution and interpolation method for computation of raster-based digital...

Raster-Based Analysis

Hardin, Eric; Mitasova, Helena; Tateosian, Laura; Overton, Margery

Pages: 27 –34

[Raster-based analysis on two or more DEMs can provide information about change patterns and trends. A common approach to mapping elevation change between two surveys is DEM differencing, performed by map algebra within GIS (r.mapcalc in GRASS). For a larger number of elevation data snapshots,...

Feature Extraction and Feature Change Metrics

Hardin, Eric; Mitasova, Helena; Tateosian, Laura; Overton, Margery

Pages: 35 –62

[Coastal change has been historically measured by metrics derived for specific coastal linear features such as shorelines. Linear features are also important for measuring sand dune migration based on the location of dune crests and slip faces and for prediction of coastal vulnerability. In this...

Volume Analysis

Hardin, Eric; Mitasova, Helena; Tateosian, Laura; Overton, Margery

Pages: 63 –70

[Coastal landform change is driven by sediment transport and redistribution of sand. In this chapter, we present techniques for mapping volumes of land mass using rectangular segments and analyzing volume evolution and redistribution in absolute and relative terms.]

Visualizing Coastal Change

Hardin, Eric; Mitasova, Helena; Tateosian, Laura; Overton, Margery

Pages: 71 –80

[Scientific visualization provides a means for effective analysis and communication of complex information that may be otherwise difficult to explain and explore. This particularly applies to coastal geomorphology, where 3D spatial and temporal patterns and relationships are critical for...
