[Geotools-gt2-users] Issues with the display of a map
Hello all,
I have a JMapFrame with a MapContent containing a raster JPG, a shapefile and 2
feature layers containing points and lines.
The frame has a checkbox that change the visibility of the shapefile layer.
When the shapefile layer is not visible, I would like
the map to be resized in order for the other layers to appear bigger (the
shapefile extent, Nz map, is a lot bigger than the other layers).
What I have in return is that, when the biggest layer is not visible the others
are visualized very small, while when it is visible, the raster
is at his biggest dimension and NZ map is cut out of the screen.
Below a piece of the code I am using to achieve the goal. I can post the whole
frame code and the files (jpg and shp) if necessary.
Any help is more than appreciated.
Thank you
Andrea
frame.enableToolBar(true);
frame.enableStatusBar(true);
JToolBar toolBar = frame.getToolBar();
JCheckBox jcb = new JCheckBox("Shape Visible", true);
toolBar.addSeparator();
toolBar.add(jcb);
jcb.addItemListener(new ItemListener() {
public void itemStateChanged(ItemEvent e) {
shpLayer.setVisible(jcb.isSelected());
recalculateBounds();
}
});
private void recalculateBounds() {
MapContent content = frame.getMapContent();
MapViewport viewport = content.getViewport();
actualBounds = viewport.getBounds();
maxBounds = null;
ReferencedEnvelope maxBounds = null;
CoordinateReferenceSystem mapCRS = viewport.getCoordinateReferenceSystem();
for (Layer layer : content.layers()) {
if(layer.isVisible()) {
ReferencedEnvelope dataBounds = layer.getBounds();
CoordinateReferenceSystem dataCrs = dataBounds.getCoordinateReferenceSystem();
if (!CRS.equalsIgnoreMetadata(dataCrs, mapCRS)){
try {
dataBounds = dataBounds.transform(mapCRS, true);
catch (TransformException e) {
e.printStackTrace();
catch (FactoryException e) {
e.printStackTrace();
}
if (maxBounds == null) {
maxBounds = dataBounds;
}else {
maxBounds.expandToInclude(dataBounds);
}
}
}
viewport.setBounds( maxBounds);
}

Re: [Geotools-gt2-users] Add attributes (fields) to a shapefile
Hi all, I’ve found a solution to the problem. In the attached file the code. It works for me.

The SimpleFeatureType of the 2 shapefiles is different, with the only common columns being the ID (and the lon and lat). They’re both CRS 2193. What I’m trying to do is to create a new shapefile with the attributes of both. adding also the collection of all the features, but it does nothing. After this command (newAttrTypes.addAll(sft2.getTypes());) I can see in the Types both set of values, But when I write them in the new shapefile I get an empty .shp The second file is generated by the first, so, theoretically, number of features and position should be the same. In the Geometry file, there are the Types for each shapefile. In the other file the code I’m using. Any help is really appreciated.

Re: [Geotools-gt2-users] GetMapRequest
Hi all, Thank you very much for your help. Unfortunately, all the options we tried didn’t work. Does the server need to be configured in order to allow wrapping or is something we can do on the client side as well? How can I check if the server allows wrapping or not? Have you got an example on how to do it on the client side in case the server is not set to allow wrapping? Thank you very much in advance for your help Andrea From: <andrea.a...@gmail.com> on behalf of Andrea Aime <andrea.a...@geo-solutions.it> Date: Friday, 23 February 2018 at 11:22 PM To: Ian Turton <ijtur...@gmail.com> Cc: Andrea Mari <andrea.m...@niwa.co.nz>, "geotools-gt2-users@lists.sourceforge.net" <geotools-gt2-users@lists.sourceforge.net> Subject: Re: [Geotools-gt2-users] GetMapRequest On Fri, Feb 23, 2018 at 11:13 AM, Ian Turton <ijtur...@gmail.com<mailto:ijtur...@gmail.com>> wrote: I think the easiest answer is to request two separate images on either side of 180/-180. Some of the data stores handle crossing the antimeridian or possibly that is all handled in GeoServer (see http://blog.geoserver.org/2010/02/23/geoserver-map-wrapping/). So you might get the correct answer by using a WMSLayer rather than making a direct WMS request yourself, but I haven't tried that. GeoServer enables that support in streaming renderer, something like this: Map<Object, Object> rendererParams = new HashMap(); rendererParams.put(StreamingRenderer.ADVANCED_PROJECTION_HANDLING_KEY, true); rendererParams.put(StreamingRenderer.CONTINUOUS_MAP_WRAPPING, true); renderer.setRendererHints(rendererParams); and then the client code should use lontidues above 180 to request an area crossing the dateline, like a WMS client does... at that point it should work...

Re: [Geotools-gt2-users] GetMapRequest
I send it again because with the attachment was too big.
Thank you very much, it works now.
Now that I’ve solved my issue, I’ve got a second one.
The real coordinates I’m using to create a rectangle in the South pacific are
getMapRequest.setBBox("162,-24,-156,17");
but due to the fact that I’m going through the 0 meridian, the Envelope doesn’t
recognise correctly the minx and maxX (it swaps them)
I’ve also tried to use 162 and 203 (assuming to use a 360 degree scale)
Any idea?
Thank you
Andrea

That URL and bounding box work fine for me, using this code
https://gitlab.com/snippets/1700238
If it fetches the whole world it is possible you are not setting the bounds of
your map viewport, so you may need to add something like (where content is your
MapContent):
content.getViewport().setCoordinateReferenceSystem(crs);
content.getViewport().setBounds(bbox);
