OHDM constists of several parts. Central core is of course the OHDM database.

Setting up an OHDM instance

OHDM uses PostGIS. First step is to install PostGIS on your machine. Create the HSTORE extension.

You most probably want to test you installation. We need to import example data. The simplest way is to use some OSM data. They are imported with a two step process:

• Import the data into an intermediate database, see OSM2Intermediate for details.
• Fill OHDM DB with data from intermediate DB, see Intermediate2OHDM for details.

All tables are created during this process. Just setup PostGIS. OHDMConverter can do the rest.

A little movie shows the whole process.

Set up OHDM 1.0 with Docker
