+
+	* doc/conf/conf.xml: Set number of per axis samples to 1024
+	  because generation of "Horizontalschnitte" is much faster
+	  now (60x).
+
+	* src/main/java/de/intevation/gnv/math/Interpolation2D.java:
+	  Added some kind of outlier test when guessing the buffer size
+	  of the spatial index. The speed problem arose from the fact
+	  that to much points are assumed to be neighbors of a given
+	  point. Long distances which differ more than 40% from the 
+	  standard derivation are assumed to be outliers.
+
+	* src/main/java/de/intevation/gnv/math/AreaInterpolation.java: Uses
+	  the outlier aware buffer size guessing now.
+
+	* src/main/java/de/intevation/gnv/raster/JTSMultiPolygonProducer.java,
+	  src/main/java/de/intevation/gnv/raster/JTSMultiLineStringProducer.java:
+	  Removed needless imports.
