[OHM] Thesis about Open Historical Map

[Jeff Meyer]

Hello Volkan!!

Thanks for your great questions! It's very exciting to know there are
others working on similar / helpful projects.

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.

1. What are the exact goals of OHM ? Which of these have already been
implemented ? Which functionalities are planned for OHM ?
The goals of OHM are:
a. Create a cool online time machine where people can come and view
depictions of high- and low-level geographic information (maps!) throughout
history.
b. Create a common, open, shared repository for vector-based map
information that users can improve.
c. I'm sure there are other goals and purposes that others on this list
might add.

2. Which functionalities have already been implemented ?
Because we are borrowing most/much of our technology from OpenStreetMap
(OSM), almost anything OSM has implemented we can currently use.
These include:
- Map database
- Raster tile service for rendering maps
- API for import / export
- Editing tools, both in-browser and external

3. Is there a way to get the map data, like an API ?
Yes, a very basic API that takes a geo bounding box for both reading and
writing to the central database.

4. Can I import maps in OHM ?
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.

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 ?
Yes! Sometime in early 2019, we hope to make this more widely available,
but an early prototype is available here:
https://openhistoricalmap.github.io/openhistoricaltiles/datefilter/#14.00/40.78411/-119.21285/2008-08-15,2008-09-15/

6. What does the data model of OHM look like ?
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.

7. How far is the development of OHM (in percent) ?
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.
What are your specific needs?

Thanks,
Jeff
