XYZ2DEM Importer - Tutorials, Examples, Applications

  The ImageJ plugin XYZ2DEM Importer imports X,Y,Z coordinates of (usually irregularly distributed) points from the first 3 columns of a plain text file and interpolates a Digital Elevation Model (DEM) image using a Delaunay triangulation.

Short Tutorials:
How to Set Appropriate Input Parameters: Let XYZ2DEM Importer comply with the requirements of your application by manually selecting appropriate input parameters. This page offers a very small data set and discusses the results of typical parameter settings. See how your parameter settings influence the resulting Digital Elevation Image.
Notes on Input Text File Formats: XYZ2DEM Importer accepts several delimiters and notations of comments. An example shows common possibilities.
Notes on Geocoding: XYZ2DEM Importer optionally keeps the geocoding of your raster image in a world file. Learn how to pass your ImageJ results to Geographic Information Systems!


Educational Tutorials Including Large Data Sets:
Import a Digital Elevation Model image of Nantucket Island. This example demonstrates the typical use of XYZ2DEM Importer using a real world data set. Using a proper chosen Maximum edge length parameter, we additionally obtain an approximate coastline.
Import a Digital Elevation Model image of Nantucket Island and apply a coastline polygon. Here we explain how to proceed if an a priori known outline polygon of the input data is given. This example is intended for comparison with the results from the strategy above.
