In EditableLayerImpl (https://github.com/neo4j/spatial/blob/master/src/main/java/org/neo4j/gis/spatial/EditableLayerImpl.java) there's a local cache for the last geometry node added to a spatial index layer.

In case of a rollback of the root transaction in which a geometry node was added, this cache will still point to a non-comitted node, so any later access to previousGeomNode leads to a NotFoundException in addGeomNode here:

previousGeomNode.createRelationshipTo(geomNode, SpatialRelationshipTypes.NEXT_GEOM);

which makes the layer index completely unwritable because there's no way to reset previousGeomNode.

A quick fix would to disable caching (see #60). This might have an impact on performance because the last added node would have been determined each time, but I wasn't able to create a better solution today.

private Node addGeomNode(Geometry geom, String[] fieldsName, Object[] fields) {

    Node geomNode = getDatabase().createNode();
    Node previousGeomNode = null; // local

    [...]

Maybe the whole thing in addGeomNode can be further optimized, e.g. with a Cypher query. It seems to be a traversal over all geometries being iterated afterwards just to find the previously added node.

Another solution perhaps would be to synchronize the cached node with transaction stuff, but that seems a fairly amount of work to me.

I get this when running 'mvn install'

OSM-Import[points:true\u002C batch:false]: one-street.osm(org.neo4j.gis.spatial.TestOSMImport$1): No index provider 'lucene' found.

shouldn't there be a dependency in the pom for this?

In order to use the neo4j-spatial artifacts, the Neo4j Snapshot Maven Repository must be used, because neo4j-spatial is not on Maven central. That introduces additional moving parts, and may not be possible in all environments.

It would make sense to upload the neo4j-spatial to Maven central, along with the other neo4j artifacts. The fact that it's a 0.x version already communicates the fact that it's not a stable/production ready release, so stability should not be a concern here.

Also, I'm guessing this has to be done at some point anyways, so the earlier the better.

Any plans to do this, perhaps in the not too distant future?

For some reason I couldn't get the mvn build work with the geotools 2.7-M3 version.
Putting it to 2.7-SNAOSHOT did the trick. Apart of the version, non geotools people might be helpless here. Just to let you know.

Hi,
I was getting this weird exception when I was running a spatial integration test:
Exception in thread "Thread-4" java.lang.NullPointerException
at org.neo4j.kernel.IndexManagerImpl$IndexCreatorThread.run(IndexManagerImpl.java:229)
Investigating it seems that the implementation of SpatialIndexImplementation - getDataSourceName is:
@Override
public String getDataSourceName() {
return null;
}
And, in IndexManagerImpl, when the new IndexCreatorThread is started, this does:
String dataSourceName = getIndexProvider( provider ).getDataSourceName();
XaDataSource dataSource = graphDbImpl.getConfig().getTxModule().getXaDataSourceManager().getXaDataSource( dataSourceName );

So essentially it doesn't find the datasource and fails with a NPE;
I am using neo4j 1.6.1 and neo4j-spatial 0.7 (not SNAPSHOT) and spring-data-neo4j 2.0.1.RELEASE

Hi,

After following the README for getting mapserver running with Neo4J-spatial, I see this error as soon as I log in as admin:

07 Sep 21:11:30 ERROR [wicket.Session] - Exception when detaching/serializing page
java.lang.OutOfMemoryError: PermGen space

The command I'm running is:

mvn jetty:run -Pneo4j

Mapserver seems to start-up just fine, but the login bombs it out.

Is there a way to bump up memory? Is this expected?

The settings of LayerNodeIndex only allows the following configurations:

Points with Lat/Long sourced from properties (named at will)
Points sourced from a WKT property (named at will) [But will accept any geometry, in practice]
Any geometry sourced from a WKB property named "" (expected non-functional)

I think it should support the following:

• Points with Lat/Long sourced from properties (named at will)
• Any geometry from a WKT property (named at will)
• Any geometry from a WKB property (named at will)

Plus, maybe:

• Points from a WKT property (named at will)
• Points from a WKB property (named at will)

Currently, Points from WKT are implemented the same as any geometry (uses WKTPropertyEncoder), and the Point nature of the index seems otherwise unused. Separating WKT/WKB points from any geometry therefore seems unnecessary.

see https://groups.google.com/forum/#!topic/neo4j/SIxUsF2EExc "neo4j-spatial: Creating a WKT-based index for polygon geometries"

Pull request to follow.

Hi peter,

I get the following failures when running "mvn install" against the current 0.9-SNAPSHOT.
I guess the cause for this problem is not on my side. If so, correct me ;)

Neo4 run into geoserver normaly,
After construction of neo4j test with this command : mvn test -Dtest=TestDynamicLayers
I have this osm layer into neo4j db : 1311178267339 (dl here if you want to test http://dl.dropbox.com/u/3026820/1311178267339.tar.gz )

I'm trying to load neostore.id with this parameter into geoserver neo4j store panel "URL connection parameters" :
file:/home/srey/TRAVAUX/THESE/REPOSITORY_GIT/neo4j-spatial/target/var/neo4j-db/1311178267339/neostore.id

I have this error :
Error creating data store, check the parameters. Error message: Could not acquire data access 'Neo4j-Spatial Test'

So i think this tutorial is outdated : http://wiki.neo4j.org/content/Neo4j_Spatial_in_GeoServer
And i'm really sorry because i can visualize neo4 data with geoserver :-/
Do you have an idea ? How can i resolve this problem ?
Thanks a lot

Hi,

I am able to get the geoserver plugin installed, and geoserver displays the neo4j-spatial data store option. However, when I configure a new data store and attempt to save, nothing happens. If I navigate to the data source listing in geoserver, I don't see my new neo4j data source. When I try to create again, I get this:

Error creating data store, check the parameters. Error message: Unable to lock store [/Applications/GeoServer.app/Contents/Resources/Java/neo4jdb/neostore.relationshiptypestore.db.names], this is usually caused by another Neo4j kernel already running in this JVM for this particular store

I've tried this on an empty directory, and an existing neo4j-spatial index directory.

Special characters like in: "förstadsgatan" in LayersTest get messed up in my checkout. Even if that could be a setting of mine, I would suggest to keep them out of the code.

They produce stuff like:
Coordinate crossing_bygg_förstadsgatan = new Coordinate( 13.0171471,
55.6074148 );
Coordinate[] waypoints_förstadsgatan = {
new Coordinate( 13.0201511, 55.6066846 ),
crossing_bygg_förstadsgatan };

Which obviously doesn't compile.

So check the type of the params and then either use them directly, or if they are a string parse JSON (or WKT?) and use the parsed result.

Example in withWithingDistance, uses params as Map directly to get "point" and "distance", it should check if it is a String and if so, parse it as JSON Map.

Hi,

when I add neo4j-spatial to my pom.xml[1], i get the following error on resolving dependencies:

Some projects fail to be resolved
Impossible to resolve dependencies of tiramisu#gastronom;0.0.1-SNAPSHOT unresolved dependency: jgridshift#jgridshift;1.0: not found
download failed: javax.media#jai_core;1.1.3!jai_core.jar

I get a similar error when adding neo4j-spatial-0.8([2]).

This error is annoying on the one hand, on the other hand it breaks my image-processing.
Following error appears when I am using "ImageIO.write()", which works fine without having neo4j-spatial-0.9SNAPSHOT in the pom.xml:

java.lang.NoClassDefFoundError: javax/media/jai/widget/ScrollingImagePanel

at domain.services.QRCodeService.createQRCode(QRCodeService.java:26)
[...]

For time being, i am unsing neo4j-spatial 0.8 to avoid the image-processing problem.

As far as I can see, this issue is caused by your dependency to geotools. Maybe it's a solution to exclude geotools image-processing.

[1]

org.neo4j
neo4j-spatial
0.9-SNAPSHOT

[2]
download failed: javax.media#jai_core;1.1.3!jai_core.jar

in Using the Neo4j Spatial Server plugin section of the readme it says that Neo4j Spatial is also packaged as a ZIP file that can be unzipped into the Neo4j Server /plugin directory.

where can i find this plugin?

neo4j-spatial (0.8 release) has a mandatory dependency on GremlinGroovyPipeline in com.tinkerpop.gremlin.groovy, but in the pom.xml, the dependency is only of type 'provided'.

This leads to a CNFE here:

In the same fashion as Neo4j.

Perhaps related - the current tests do not run on a Mac OS X Lion 10.7.2 MacBook Pro with 8GB memory (varying errors on different runs).

I am trying to build neo4j-spatial

maven version problem??

is this not problem?

This isn't a problem with neo4j spatial, but is causing the build to fail. I've resolved the issue by manually altering my m2 repository to include the correct asm-3.1.pom and asm-3.1.jar in /asm/3.1 and adding /asm-parent/3.1/asm-parent-3.1.pom. These files were available from the asm website.

Cheers,

Note: This occurred using maven 2.

While implementing a function on top of SimplePointLayer I found a flaw in the above function. The second parameter (distance) is never used but the function always searches with a fixed radius of 10km. The fix is quite easy:

SearchPointsWithinOrthodromicDistance distanceQuery = new SearchPointsWithinOrthodromicDistance(point, distance, true);

[cf. https://github.com/neo4j/neo4j-spatial/blob/master/src/main/java/org/neo4j/gis/spatial/SimplePointLayer.java#L48]

My workaround for this issue was to reimplement the following function in user-space:
List findClosestPoints(SearchPointsWithinOrthodromicDistance)

Is there a 'non batch' OSM inserter? There were allusions to this but I can't seem to find any and the OSMBatchInserter blows up with an out-of-memory exception with a large number of Nodes/Ways. I'd be happy to use ruby or python but can't seem to get those setup either.

Hi!

I think having detected a bug in SearchClosest, namely the onIndexReference() - method seems not to be correct since it
excludes Geometries which could be nearer than another Geometry.

public final void onIndexReference(Node geomNode) {
Envelope geomEnvelope = getEnvelope(geomNode);
if (searchWindow == null || geomEnvelope.intersects(searchWindow)) {
onEnvelopeIntersection(geomNode, geomEnvelope);
}
}

Problem is that if envelops do not intersect, onEnvelopeIntersection() method is not entered.

I currently play around with neo4j and i occassionally found a case where a geometry which does not intersect with Envelope is the nearer.

In my case I created a very short Linestring, a very long Linestring and a point from which the distance to the small Linestring is shorter than to the long Linestring.

Problem is that the envelope of the short linestring does not intersect with the search window, but the envelope of the long Linestring does and so the long Linestring wins, which is not correct.

The short LineString is "LINESTRING(16.3493032 48.199882,16.3479487 48.1997337)"
The long LineString is "LINESTRING(16.3178388 48.1979135,16.3195494 48.1978011,16.3220815 48.197824,16.3259696 48.1978297,16.3281211 48.1975952,16.3312482 48.1968743,16.3327931 48.1965196,16.3354641 48.1959911,16.3384376 48.1959609,16.3395792 48.1960223,16.3458708 48.1970974,16.3477719 48.1975147,16.348008 48.1975665,16.3505572 48.1984533,16.3535613 48.1994545,16.3559474 48.2011765,16.3567056 48.2025723,16.3571261 48.2038308,16.3578393 48.205176)"

Simplify lookup methods by putting the behavior into different classes.

Implement putIfAbsent, make sure that remove removes the node.

Improve exception handling (e.g. in remove)

This a very small issue, but in your first example you show the shapefile importer with the shapefile's path and extension. However, in the code http://github.com/neo4j/neo4j-spatial/blob/master/src/main/java/org/neo4j/gis/spatial/ShapefileImporter.java#L118 the shapefile import appends the path with a file extension.

This is not a biggie, but could cause pain to new users.

EditableLayerImpl#addGeomNode finds the last geo node in the traversal path. For longer paths where there are a large number of nodes in the layer, the logic to traverse the entire path just to find the last node will result in unacceptable performance. Using a postorderBreadthFirst ordering will vastly improve the performace, as the levels are selected starting at the deepest depths.

See https://github.com/bm3780/spatial/commit/60accf4d8cb3310f327edb0e2233ae15a9a1426b for changes.

org.neo4j.gis.spatial.indexprovider.LayerNodeIndex#add doesn't seem to conform to the org.neo4j.graphdb.index.Index#add interface specifications:

"Adds a key/value pair for entity to the index. If that key/value pair for the entity is already in the index it's up to the implementation to make it so that such an operation is idempotent."

In my tests, calling LayerNodeIndex#add N number of times for the same Node resulted in N number of nodes being added to the corresponding Spatial Layer for that index.

I can't get the neo4j-geoserver plugin to work (GeoServer 2.1.4, MacOS) when I follow the instructions on the main page, GeoServer starts up, and in the console are errors (errors pasted below). The only way I got this to work is to copy the neo4j lib contents (from the downloaded distribution) into GeoServer WEB-INF/lib, then copy ONLY the neo4j-spatial-0.9-SNAPSHOT.jar into GeoServer WEB-INF/lib. So maybe this is just a documentation issue?

The following exception occured when I was trying to update a node with spatial data:

org.neo4j.graphdb.NotFoundException: More than one relationship[RTREE_REFERENCE, INCOMING] found for NodeImpl#14271

This is using neo4j-spatial v0.8 with neo4j 1.7.

Node 14271 has these properties:

id: 14270
bbox: [-112.36,33.45,-112.36,33.45]
wkt: "POINT (-112.36 33.45)"
gtype: 1

It had two incoming RTREE_REFERENCE relationships to nodes with the bbox property:

bbox: [-112.36,33.45,-112.07,33.45]

The other one I deleted, so that the app would work properly, but it had a bbox value slightly different, but one that would enclose the point in node 14271.

I don't have a test that will reproduce this, and I frankly have no idea how it happened. I could NOT reproduce this on my own after I deleted the second relationship.

Hi

I get a build failure (message below) on OSX Mountain Lion using commit 208f841. I have tried building with both Java 1.6 and 1.7. I am using maven 2 from Mac Ports.

Help!

Until the latest version of Neo4j Spatial builds, we're using an older checkout (and building against Neo4j 1.6) -- however, on a fresh Java & Maven installation on our deployment server, it refuses to build, citing a dependency error. The full output is at https://gist.github.com/2551961 -- the offending POM (http://maven.glassfish.org/content/groups/glassfish/net/java/jvnet-parent/1/jvnet-parent-1.pom) seems to have been moved by Oracle?

Can anyone help with this?

is there something somewhere? I couldn't find anything but the Readme.

thanks

I was needing to add features similar to the restrictLayerProperties feature I added a month ago, and found, to my horror, that the code was missing. On a search of the github history, I found that about 30-40 lines of nice code was deleted from DynamicLayer.java on the 7th September by Peter as part of RTree refactoring. The commit is at fa3214b#diff-7

I will see if I can recover the old code, but I am very curious as to why this feature was deleted. Is it possible that someone did the RTree refactoring on an old branch, and merged that into master without first merging from master?

I found the http://components.neo4j.org/neo4j-spatial/ page have been remove ,so i can't to reach the road map of this project.Is there any idea about it?

In order to build the Spatial Index Provider with CQL, I would need an example on how to search CQL in a Layer. Any hints on that?

Hi,
I make a git clone of master default branch, after an mvn install, here the log of error :

(http://groups.google.com/group/neo4j/browse_thread/thread/630dc8ce8c87cf06)

it seems when deleteing a node containing a wkt property the wkt property is not removed from the index, even the node is cleanly removed from the DB. This might result in a NotFoundException in case of spatial search execution as nodes will be returned which actually are no more present in the DB.

Workaround/hack: catch NotFoundException and treat this as a common bahavior..

cheers, Florian;

Currently, there is no way to use Cypher or Gremlin to search the Spatial Index for all geo nodes within a distance. See discussion topic for more details. http://neo4j-community-discussions.438527.n3.nabble.com/Neo4j-Using-Webadmin-Console-to-Execute-Spatial-Cypher-Query-tp3500531p3500531.html;cid=1321303030769-259

As a workaround, having this ability via the SpatialPlugin would be beneficial.

I've already taken a shot at adding this capability here -> https://github.com/bm3780/spatial/blob/master/src/main/java/org/neo4j/gis/spatial/server/plugin/SpatialPlugin.java

I've updated the SpatialPluginTests here ->
https://github.com/bm3780/spatial/blob/master/src/test/java/org/neo4j/gis/spatial/ServerPluginTest.java

Exception:

The following Lucene search finds more than one Node and throws an exception. Only the Node inside the current Layer should be returned:

            Node node = changesetNodes.get(osmId);
            if (node == null) {
                logNodeFoundFrom("node-index");
                return indexFor("node").get("node_osm_id", osmId).getSingle();
            } else {
                logNodeFoundFrom("changeset");
                return node;
            }

Obtaining a pre-existing spatial index (LayerNodeIndex) with IndexManager.forNodes(indexName, customConfiguration) throws an IllegalArgumentException.

This is due to SpatialIndexProvider.configMatches(stringStringMap, stringStringMap1) returning false no matter what the parameters.
