[OHM] Thesis about Open Historical Map

[Rob H Warren]

Volkan,

Good to hear from you. The data from is available as a dump or minute updates at [1]. 

The separation between geometry & feature which your data project takes on and is to my mind a core component of GeoSparql is key to good historical mapping. However, OHM is still wedded to the increasingly messy OSM software ecosystem which was designed without that separation. 

I've been tinkering with sparkfly to output a linked open data version of OHM, however the software suffers from poor maintenance and requires yet another java virtual engine to be running. I have an idea of hacking together a translation layer off of the tiling database to output proper geosparql triples along with OWL-TIME [2] compliant instances, but it's a long term project. 

Look forward to reading your published thesis,
R.

> Hello Open Historical Mapper :),
> 
> my name is Volkan, I'm from Berlin, Germany and I currently study applied computer science at HTW-Berlin (Hochschule für Technik und Wirtschaft).
> I'm currently working on my thesis and the title is "Usability of Open Historical Map for Open Historical Data Map".
> Open Historical Data Map is like OHM a open source project by Prof. Dr. Thomas Schwotzer. He is my professor at the university.
> The goal of OHDM is to create historical maps.
> 
> There are a few things I need to know about OHM for my thesis:
> 
> 1. What are the exact goals of OHM ? Which of these have already been implemented ? Which functionalities are planned for OHM ?
> 2. Which functionalities have already been implemented ?
> 3. Is there a way to get the map data, like an API ?
> 4. Can I import maps in OHM ?
> 5. Can I filter the map for a specific year, like I would like to see a map from 1907, if not, will this functionality implemented soon ?
> 6. What does the data model of OHM look like ?
> 7. How far is the development of OHM (in percent) ?
> 
> I know that's a lot of questions but I hope you guys can help me out :)
> 
> Wish you all a great day and merry christmas :)
