 2010-01-24	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
 
+	* doc/conf/conf.xml: Added attribute "fill-color" to
+	  /artifact-database/gnv/vertical-cross-section/ground/ configure
+	  the color of the seabed polygon.
+
+	* src/main/java/de/intevation/gnv/math/Interpolation3D.java:
+	  Adjusted column depth to the deepest interpolated position to
+	  prevent gaps.
+
+	* src/main/java/de/intevation/gnv/chart/VerticalCrossSectionChart.java:
+	  Add ground polygon to the chart.
+
+	* src/main/java/de/intevation/gnv/state/profile/verticalcrosssection/OutputHelper.java:
+	  New. Contains code to create the ground polygon.
+
+	* src/main/java/de/intevation/gnv/raster/PolygonDatasetProducer.java,
+	  src/main/java/de/intevation/gnv/raster/IsoPolygonSeriesProducer.java:
+	  Handle temporary vertices more efficiently.
+
+	* src/main/java/de/intevation/gnv/artifacts/context/GNVArtifactContext.java,
+	  src/main/java/de/intevation/gnv/artifacts/context/GNVArtifactContextFactory.java:
+	  Added configuration to set the color of the seabed polygon.
+
+	* src/main/java/de/intevation/gnv/chart/VerticalCrossSectionChart.java:
+	  Handle the seabad polygon color.
