Hi Jody,
I tried those 3 ways :
String startDateString = "28/04/2009";
String endDateString = "29/04/2009";
DateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
java.util.Date startDate = null;
java.util.Date endDate = null;
try
{
startDate = (Date)formatter.parse(startDateString);
endDate = (Date)formatter.parse(endDateString);
}
catch (ParseException e)
{
e.printStackTrace();
}
FeatureStore<SimpleFeatureType,SimpleFeature> fs = getFeatureStore("roads");
GeometryFactory geomFactory = new GeometryFactory();
Point point = geomFactory.createPoint( new Coordinate(0, 0));
FeatureCollection<SimpleFeatureType, SimpleFeature> collection = FeatureCollections.newCollection("internal");
(1) ----- final SimpleFeature feature = SimpleFeatureBuilder.build( fs.getSchema(), new Object[] {new java.sql.Timestamp(startDate.getTime()), new java.sql.Timestamp(endDate.getTime()), "bla bla", point}, null );
(2) -----final SimpleFeature feature = SimpleFeatureBuilder.build( fs.getSchema(), new Object[] {startDate, endDate, "bla bla", point}, null );
(3) -----final SimpleFeature feature = SimpleFeatureBuilder.build( fs.getSchema(), new Object[] {"2009-04-28T00:00:00", "2009-04-29T00:00:00", "bla bla", point}, null );
collection.add(feature);
fs.addFeatures(collection);
And I get thoses Errors:

For the first case, It works with a PostGIS data store but not with WFS-T data store (GeoServer)
I think the format defined here : http://www.w3.org/TR/xmlschema-2/#dateTime is not respected
It looks like a 'T' is missing between the date and the time. It should be 2009-04-28T00:00:00.0.
Is this a bug? I'm Using Geotools 2.5.4.
Can I find a working example somewhere ?
Thank You,
Yako Bak.

Hi list, I have a question that could be more related to a jts-user list but hopefully someone can help me. I have two set of Geometry objects (a set of Points and a set of Multipolygons) and I have to check which of them intersect to get the mapping of Polygon->Points. geometryObjectA.intersect(geometryObjectB) returns true or false and the simplest but quite inefficient solution is: two nested loops iterating over both sets and check each pair if it intersects. Since a point could be intersected by more than polygon (if it lies on a edge or even a vertex) no breaks could be used in the loops. Very inefficient, or? I'm neither an expert in algorithm optimization nor in jts and geotools libs therefore I'd like to know: Are there convenience functions in one of them that offer optimized algorithms for interection/union/.. tasks of geometry sets? If not: What should I do instead of iterating two times over these sets? The Multipolygons are quite complex (>1000 or even >10000 vertices and consisting of several polygons). I was thinking of first intersecting the Points with the envelope of the Multipolygons and only if this matches checking the Multipolygon itself. Other optimization ideas? Barking up the wrong tree? I was also thinking of storing the MultiPolygons in a (spatial) database, create an index and le the database do the intersection and hope that they have optimized it :-) Thanks for any help!

I would try it in the following manner 1) Take your points and sort them primary by x value, secondary by y value, eliminate duplicates 2) Create a linestring from your points, step 1 should assure a valid geometry 3) intersect the linestring with the mulitpolygon, the result can be an empty geometry, a linestring or a multilinstring. 4) You need only one loop Cheers Quoting Jürgen Jacob <zoi...@gm...>: > Hi list, > I have a question that could be more related to a jts-user list but > hopefully someone can help me. > > I have two set of Geometry objects (a set of Points and a set of > Multipolygons) and I have to check which of them intersect to get > the mapping of Polygon->Points. > geometryObjectA.intersect(geometryObjectB) returns true or false and > the simplest but quite inefficient solution is: two nested loops > iterating over both sets and check each pair if it intersects.

Dear list, i have created a simple stand alone map viewer using GeoTools 8.3 i try to select one feature using SelectionLab. It work fine. i want the users to be able to select more as one feature from a shape file in the map. (a la select with frame) how can i do it? Could anyone point me in the right direction? Do i have to use a filter? Any help will be greatly appreciated. Kind regards, Eik Beck |

Hello Erik, > i want the users to be able to select more as one feature from a shape file > in the map. (a la select with frame) > how can i do it? > Could anyone point me in the right direction? Do i have to use a filter? The tutorial is already pointing you in the right direction for this. If you study the code for the selectFeatures method... http://docs.geotools.org/latest/userguide/tutorial/map/style.html#what-features-did-the-user-click-on ...you can see that a rectangle (ReferencedEnvelope object) is being constructed from a mouse click position which is then used in a filter. You will have a rectangle instead of a click position but can use the rest of the code from that method unmodified since it already handles the case of multiple selected features. Michael |

hallo Michael I'm sorry that it is so incomprehensible. I will be as a kind of built like a simple editor, evaluate the text files and reads with them interactively with the help of GeoTools changes. Therefore I need the one with shapfile geometries and the other a sld-file with styles. sld-file for simplicity in this example is applied statically. I want to create styles for later programmatically. now... what do i have to do if i want to change a value of a layer in memory? what i'm trying to do is, write a new value in the store. i tried using store.modifyFeatures() and a transaction.... it seems like layer is not going to be changed? or maybe im totaly on the wrong way in how to change the data? i would really appreciate your help guys. thanks Erik |

OK. Now after much banging the head on the wall, I came to realize that my code would only work if I have a .pgw (world) file along with the .png file I get from the WMS server. Now can anyone tell me how do I make a .pgw file from geotools or even geoserver?

Well if you are just debugging the image format (to see if java can read it you can use ImageIO directly): img = ImageIO.read(anImageFile); Reference: http://docs.oracle.com/javase/tutorial/2d/images/loadimage.html -- Jody Garnett On Monday, 5 November 2012 at 12:48 AM, Ratnadeep Raxsith wrote: > OK.

in org.geotools.tutorial.quickstart (QuickStart.java), The following packages do not exist: import org.geotools.map.FeatureLayer; import org.geotools.map.Layer; import org.geotools.map.MapContent; I followed this tutorial: http://docs.geotools.org/latest/userguide/tutorial/quickstart/netbeans.html Robert |

Robert, these classes are from gt-render, which should be on your classpath if you have a dependency on gt-swing. Do you have any Maven project errors in NetBeans? Can you build your project from the command line with "mvn clean install"? Kind regards, Ben.

Hi all, I am writing a simple application to parse some geometries from GeoJSON to GML and viceversa. I am able to accomplish my goal, but I cannot write neither in GML or GeoJSON the srsName. For example the actual result is <?xml version="1.0" encoding="UTF-8"?><gml:Polygon xmlns:gml=" http://www.opengis.net/gml" xmlns:sch="http://www.ascc.net/xml/schematron" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xlink=" http://www.w3.org/1999/xlink" srsDimension="2"><gml:exterior><gml:LinearRing srsDimension="2"><gml:posList>12.2678 45.5224 12.2678 45.5224 12.2678 45.5224 12.2677 45.5224 12.2678 45.5224 12.2677 45.5224 12.2677 45.5224 12.2677 45.5224 12.2677 45.5224 12.2677 45.5224 12.2678 45.5224 12.2678 45.5224 12.2678 45.5224</gml:posList></gml:LinearRing></gml:exterior></gml:Polygon> but the expected is <?xml version="1.0" encoding="UTF-8"?><gml:Polygon xmlns:gml=" http://www.opengis.net/gml" xmlns:sch="http://www.ascc.net/xml/schematron" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xlink=" http://www.w3.org/1999/xlink" srsDimension="2" srsName="EPSG:4326" ><gml:exterior><gml:LinearRing srsDimension="2"><gml:posList>12.2678 45.5224 12.2678 45.5224 12.2678 45.5224 12.2677 45.5224 12.2678 45.5224 12.2677 45.5224 12.2677 45.5224 12.2677 45.5224 12.2677 45.5224 12.2677 45.5224 12.2678 45.5224 12.2678 45.5224 12.2678 45.5224</gml:posList></gml:LinearRing></gml:exterior></gml:Polygon> There is a way to do this kind of stuff?
