<div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr">Hello Volkan!!<div><br></div><div>Thanks for your great questions! It's very exciting to know there are others working on similar / helpful projects.</div><div><br></div><div>First, there are a few things we're working on for OHM that will make the future OHM slightly different from what's available today. I'll try to distinguish between the two where appropriate. Hopefully, this won't be too confusing.</div><div><br></div><div><div>1. What are the exact goals of OHM ? Which of these have already been implemented ? Which functionalities are planned for OHM ?</div><div>The goals of OHM are:<br></div><div>a. Create a cool online time machine where people can come and view depictions of high- and low-level geographic information (maps!) throughout history.<br>b. Create a common, open, shared repository for vector-based map information that users can improve.</div><div>c. I'm sure there are other goals and purposes that others on this list might add.</div><div><br></div><div>2. Which functionalities have already been implemented ?</div><div>Because we are borrowing most/much of our technology from OpenStreetMap (OSM), almost anything OSM has implemented we can currently use.</div><div>These include:</div><div>- Map database</div><div>- Raster tile service for rendering maps</div><div>- API for import / export<br>- Editing tools, both in-browser and external</div><div><br></div><div>3. Is there a way to get the map data, like an API ?</div><div>Yes, a very basic API that takes a geo bounding box for both reading and writing to the central database.</div><div><br></div><div>4. Can I import maps in OHM ?</div><div>Certainly, although you may need to convert your GIS files into OSM formats and we ask that there be start_date and end_date and source tags added to all your ways.</div><div><br></div><div>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 ?</div><div>Yes! Sometime in early 2019, we hope to make this more widely available, but an early prototype is available here:</div><div><a href="https://openhistoricalmap.github.io/openhistoricaltiles/datefilter/#14.00/40.78411/-119.21285/2008-08-15,2008-09-15/">https://openhistoricalmap.github.io/openhistoricaltiles/datefilter/#14.00/40.78411/-119.21285/2008-08-15,2008-09-15/</a><br></div><div><br></div><div>6. What does the data model of OHM look like ?</div><div>We use the OSM data model, which you can learn more about at the OSM wiki, but it loosely consists of basic GIS data types that have associated key:value pairs.</div><div><br></div><div>7. How far is the development of OHM (in percent) ?</div></div></div><div>Hard to say & it depends on whether you'd include what OSM has already built into that estimate. Regardless, we have a fair amount of customization we'd like to do.</div><div>What are your specific needs?</div><div><br></div><div>Thanks,</div><div>Jeff</div><div><br></div><div dir="ltr"><br></div><br><div class="gmail_quote"><div dir="ltr">On Thu, Dec 27, 2018 at 8:40 AM "Volkan Özgen" <<a href="mailto:volkan.oezgen@web.de">volkan.oezgen@web.de</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div><div style="font-family:Verdana;font-size:12px"><div style="font-family:Verdana;font-size:12px">
<div>Hello Open Historical Mapper :),</div>
<div> </div>
<div>my name is Volkan, I'm from Berlin, Germany and I currently study applied computer science at HTW-Berlin (Hochschule für Technik und Wirtschaft).</div>
<div>I'm currently working on my thesis and the title is "Usability of Open Historical Map for Open Historical Data Map".</div>
<div>Open Historical Data Map is like OHM a open source project by Prof. Dr. Thomas Schwotzer. He is my professor at the university.</div>
<div>The goal of OHDM is to create historical maps.</div>
<div> </div>
<div>There are a few things I need to know about OHM for my thesis:</div>
<div> </div>
<div> 1. What are the exact goals of OHM ? Which of these have already been implemented ? Which functionalities are planned for OHM ?</div>
<div><span> 2. </span>Which functionalities have already been implemented ?</div>
<div><span>3. Is there a way to get the map d</span><span>ata, like an API </span><span>?</span></div>
<div> 4. Can I import maps in OHM ?</div>
<div> 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 ?</div>
<div> 6. What does the data model of OHM look like ?</div>
<div>
<div> 7. How far is the development of OHM (in percent) ?</div>
<div> </div>
<div>I know that's a lot of questions but I hope you guys can help me out :)</div>
<div> </div>
<div>Wish you all a great day and merry christmas :)</div>
<div> </div>
<div>Greetings from Germany</div>
