Introducing GeoDB

GeoDB is a spatial extension of the H2, the Java SQL database. GeoDB utilizes the JTS library as its geometry engine and the Hatbox library for spatial indexing support.

Quickstart

• Download GeoDB
• Unzip the geodb-0.1-app.zip file
• Update the PATH environment variable to include geodb-0.1/bin
• Run the geodb command:

% geodb foo

• Initialize the spatial database:

@h2> CREATE ALIAS InitGeoDB for "geodb.GeoDB.InitGeoDB"
@h2> CALL InitGeoH2()

• Create a spatial table:

@h2> CREATE TABLE spatial (id INT AUTO_INCREMENT PRIMARY KEY, geom BLOB)

• Create some spatial data:

@h2> INSERT INTO spatial (geom) VALUES (ST_GeomFromText('POINT(0 0)', 4326))
@h2> INSERT INTO spatial (geom) VALUES (ST_GeomFromText('POINT(1 1)', 4326))
@h2> INSERT INTO spatial (geom) VALUES (ST_GeomFromText('POINT(2 2)', 4326))

• Create a spatial index:

@h2> CALL CreateSpatialndex(NULL, 'spatial', 'geom', 4326)
