Merano Open Data Imported

An interlude from India to Italy. Back in November, the municipality of Merano released _all_ of their GIS data, so that it could be imported into OpenStreetMap, or reused in any other manner. We’ve now completed the first round of import of that data, into OpenStreetMap and OpenAerialMap. Merano is liberated!

OSM Merano

OAM Merano

Thanks to Cristiano Giovando for importing the roads data and Christopher Schmidt for processing the aerial imagery.

There was some existing road data in Merano, so Cristiano manually solved those conflicts. Still this needs review by someone familiar with Merano, and highway classification, which was not present in the data, needs to be applied to roads.

The aerial imagery for the most part was processed fine, but there were a few anomalies which need to be debugged, and reprocessed at some point.

There’s a whole lot more data — this is just 2 of a dozen layers. I have an DVD from the city, which we discussed hosting at Telescience in San Diego. Get in touch if you want to take a look at this data.

    […] Sería genial que las autoridades vascas (y vascos, y del resto del mundo también) dieran el paso fundamental: liberar la cartografía y la imagen pública. La ciudad italiana de Merano, en el Tirol del Sur, dio el paso hace poco, y hoy se ha anunciado que en OpenStreetMap se puede ver ya el callejero libre de la ciudad, y en OpenAerialMap la ortofoto integrada. […]

    One of the main doubts that I have detected in (open-minded) local authorities with public geodata when weighing this step taken in Merano is: is this “integration” or is it a “fork”?

    I mean, Merano’s data goes to OSM and OAM, is processed and looks great. Now, Merano will keep updating its geodata in… its own databases? When new roads are built, what will happen? or what will happen to the new labels that will be added in OSM, not present in the original? OSM edits by the users at large, will go back to Merano’s servers?

    The first import is a great achievement. And the next one?

    Merano internally has an OSM like GIS — everyone employed by the city contributes information directly to the GIS, within their jurisdiction. Gardners update the locations of trees (yes the Merano GIS has the location of every one), etc. So the release of data is a fork, and we didn’t discuss anything about updates in the future, though that might be possible on request.

    This is a really complex issue. The Sudan import from the UN was done in the context of the UNSDI-t process (UN Spatial Data Infrastructure – Transport) and they’re grappling with the interchange of geographic data updated and shared among many different agencies. Andrew has been attending a meeting there this week, and he may have more to share later on.

    We’re really at the edges of the possible here .. as usual!

    Excellent news! I grew up in Meran, and did some of the preexisting osm maps from the gps traces I recorded last xmas. It’s great to come back and find find a perfectly accurate and complete map. Road classification is really the only thing that’s missing. I’ll take a look at it soon. Kudos to everyone involved!

    […] Working for government action at the national level is like moving a mountain range. There’s much more possibility to have an affect in your local government. Oakland Crimespotting motivated the Oakland PD to release their data in a machine readable format. Merano Italy released a treasure trove of CC-SA data. Inspire your local government with these examples and , and push for truly free and open data .. leading to democracy, participation, and an inventive public life. […]
