[Robin Patzelt (JIRA)]

Title: Message Title

Robin Patzelt created an issue   GeoTools / GEOT-5459 Java Heap-Exeption during Geometry#buffer for a specific Line-Geometry Issue Type: Bug Affects Versions: 14.3, 8.4 Assignee: Unassigned Attachments: testImport.csv Components: geometry, jts-wrapper Created: 05/Jul/16 10:33 AM Environment: Windows 7 JDK 1.8 64bit Labels: buffer jts geometry Priority: Medium Reporter: Robin Patzelt during the buffer calculation of the Geometry in the attachet file a HeapException occure. This Exception only occurs on this line geometry. The calculation on other line with more coordinates works perfectly. The buffer to calculate is 5000m. the used code for the calcution: private static Geometry usingJTS(final Geometry geometry, final double meters) throws NoSuchAuthorityCodeException, FactoryException, TransformException { final CoordinateReferenceSystem lambert = CRS.decode("EPSG:31300",true); MathTransform convertToMeter = CRS.findMathTransform(DefaultGeographicCRS.WGS84, lambert,false); MathTransform convertFromMeter = CRS.findMathTransform(lambert, DefaultGeographicCRS.WGS84,false); Geometry geometryWithBuffer; // Umrechnen in Lambert geometryWithBuffer = JTS.transform(geometry, convertToMeter); // buffer in Metern geometryWithBuffer = geometryWithBuffer.buffer(meters); // Geometry zurück nach WGS 84: geometryWithBuffer = JTS.transform(geometryWithBuffer, convertFromMeter); return geometryWithBuffer; } The Exception: <STACKTRACE TIMESTAMP="04.07.2016 17:09:48" |rsClient|NWN_5.19.0.0|7740|ROOT=""> java.lang.OutOfMemoryError: Java heap space at com.vividsolutions.jts.geomgraph.Depth.<init>(Depth.java:56) at com.vividsolutions.jts.geomgraph.Edge.<init>(Edge.java:73) at com.vividsolutions.jts.operation.buffer.BufferBuilder.computeNodedEdges(BufferBuilder.java:205) at com.vividsolutions.jts.operation.buffer.BufferBuilder.buffer(BufferBuilder.java:150) at com.vividsolutions.jts.operation.buffer.BufferOp.bufferOriginalPrecision(BufferOp.java:357) at com.vividsolutions.jts.operation.buffer.BufferOp.computeGeometry(BufferOp.java:323) at com.vividsolutions.jts.operation.buffer.BufferOp.getResultGeometry(BufferOp.java:317) at com.vividsolutions.jts.operation.buffer.BufferOp.bufferOp(BufferOp.java:193) at com.vividsolutions.jts.geom.Geometry.buffer(Geometry.java:1176) at com.rola.rscase.gis.RolaGeotools.GeoToolsUtil.usingJTS(GeoToolsUtil.java:510) at com.rola.rscase.gis.RolaGeotools.GeoToolsUtil.getBufferInMeters(GeoToolsUtil.java:409) at com.rola.rscase.gis.BufferPanel$1.actionPerformed(BufferPanel.java:171) at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:2022) at javax.swing.AbstractButton$Handler.actionPerformed(AbstractButton.java:2346) at javax.swing.DefaultButtonModel.fireActionPerformed(DefaultButtonModel.java:402) at javax.swing.DefaultButtonModel.setPressed(DefaultButtonModel.java:259) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(BasicButtonListener.java:252) at java.awt.AWTEventMulticaster.mouseReleased(AWTEventMulticaster.java:290) at java.awt.Component.processMouseEvent(Component.java:6525) at javax.swing.JComponent.processMouseEvent(JComponent.java:3324) at java.awt.Component.processEvent(Component.java:6290) at java.awt.Container.processEvent(Container.java:2234) at java.awt.Component.dispatchEventImpl(Component.java:4881) at java.awt.Container.dispatchEventImpl(Container.java:2292) at java.awt.Component.dispatchEvent(Component.java:4703) at java.awt.LightweightDispatcher.retargetMouseEvent(Container.java:4898) at java.awt.LightweightDispatcher.processMouseEvent(Container.java:4533) at java.awt.LightweightDispatcher.dispatchEvent(Container.java:4462) at java.awt.Container.dispatchEventImpl(Container.java:2278) at java.awt.Window.dispatchEventImpl(Window.java:2750) at java.awt.Component.dispatchEvent(Component.java:4703) at java.awt.EventQueue.dispatchEventImpl(EventQueue.java:758) </STACKTRACE> Add Comment   This message was sent by Atlassian JIRA (v1000.126.1#100004-sha1:15ab2b1)
