Why the name Gisgraphy?

It is geography for GIS (aka Geographic Information System).

How long does it take to import all of the data?

It depends on the machine and the memory. On a core2 Duo it takes about 24 hours. If you need a Postgres dump or solr dump contact me.

[top]
The project is young, has it been tested?

It has been tested on several machines using linux, Windows and various JVMs. Gisgraphy has high unit/integration test coverage.

[top]
Will the project go on?

Yes, I plan to keep the development going.

[top]
Who are the developers?

Me and myself : David Masclet:)

What technology is used?

Java / Spring / Hibernate / Hibernate Spatial / Maven 2 / PostGIS / PostgreSQL / Jersey (CXF when V2.1 is released).

Can Gisgraphy run on Java 1.4?

Gisgraphy is designed for Java 1.5 but you can try this tool.

[top]
Is it possible to only Import the countries I'm interested in?

Edit the importer.filesToDownload option in the env.properties file. Set the country you want to download and process. Or, if you don't want Gisgraphy to download files; set the importer.retrieveFiles option to false and put the files you want to process in the 'importer.geonames.dir' directory.

[top]
Is it possible to only Import the features I'm interested in?

Yes, just edit the importerConfig.acceptRegExString option. See user the guide.

[top]
Is it possible to customize placetype?

Yes, you can find some information here.

On Linux / Unix, I get the messge "Too many open files", what does it mean?

It is due to SolR < = > Unix, you need to update the max numbers of open files on your system. See this link and this one for help.
