[Neo4j] GSoC 2011 Neo4j Geoprocessing | Weekly Report #12
Hello, In the final week I didn?t had much time so I only added some more code documentation. There still things to do and I will continue to working on this even Google Summer of Code is now ending. It was an enjoyable time, I have learned many new things and I would like to thank my mentors Peter and Craig, and OSGeo to give me this chance.

Hi, This week I spent the most of the time with documentation, code refactoring and performance optimization. Also did some benchmarking with Neo4j Spatial and PostgreSQL/Postgis(GeoServer).

Re: [Neo4j] neo4j spatial and postgis
Hi, with the pgsql2shp tool you can dump your postgis db in a shapefile and you should be able to import it in Neo4j Spatial in the following way: String shpPath = SHP_DIR + File.separator + layerName; ShapefileImporter importer = new ShapefileImporter(graphDb(), new NullListener(), commitInterval); importer.importFile(shpPath, layerName); Best Regards Andreas Am 12.08.2011 11:10, schrieb chen zhao: Hi, I very interested in neo4j spatial . but I do not know how to import the spatial data. My data are stored in postgis. I read the document http://wiki.neo4j.org/content/Spatial_Data_Storage; and http://wiki.neo4j.org/content/Importing_and_Exporting_Spatial_Data,but I yet do not know to to import data from postgis or import shapfiles.

Hi, This week I started with my second phase of GSOC which means to create an Neo4j geoprocessing example in uDig. For that I set up the development environment for uDig. Also added some more code comments to the spatial functions and installed the doc-toolchain for Neo4j (Spatial). Currently I´m checking the GeoServer integration of Neo4j Spatial.

It should be working with all layers which are implementing the EditLayer or Layer interface, but I tested it only with OSMLayer.

Hi, This week I wrote some overview documentation for the code review, added full delete operation for OSMLayer graph model - with relation rebuilding of the remaining geom nodes and added some more spatial type functions: ST_Area, ST_Box2D, ST_Buffer, ST_Centroid, ST_Length, ST_MaxX, ST_MinX, ST_MaxY, ST_MinY.

Hi, This week I had a little blocker with deleting some subgraph nodes and relations. For that I made a seperate test to identify the problem and try to find a solution. Apart from that I integrated a additonal spatial type function to get the distance between geometry nodes and updated the already existing spatial type functions to the new API.

Hello, This week I did some reworking of the spatial CRUD implementation where I´m still currently working on. Integrated new spatial type functions like to simplify geometries with the Douglas-Peucker algorithm, getting start and endpoint of a geometry and the union of geometries.

Hi, This week I implemented basic insert and delete capability for Neo4j Spatial type functions, added ST_GeomFromText as a new spatial function and at the moment I prepare everything to be able to commit it to the main repository of Neo4j Spatial, this means testing, documentation, etc...

Well first I should add some more documentation/comments :-P and then we could review the code. Am 07.06.2011 22:29, schrieb Craig Taverner: I suggest you code review them first.

Hi, One requirement of Google Summer of Code is that I give a weekly status report. So this week I started with spatial transform and update functionality on Neo4j Spatial. There a still some problems with updating which I will focus next week and implementing some more spatial functions.
