The good thing about the maps we have chosen is that, based on the 1830 to 1850 time period, there isn't significant overlap of map content. However, there are overlapping borders that do need to be cropped out.<br>
<br>
I am hesitant to use Map Warper for these historic maps, as the features on the map are mostly natural. But I could be convinced. Here's our current methodology for georeferencing: <a href="https://www.dropbox.com/s/g2fz8ti9npmbh30/Tutorial_and_Methodology_for_Mapping_Historic_Wetlands.pdf?dl=0" rel="noreferrer" target="_blank">https://www.dropbox.com/s/g2fz8ti9npmbh30/Tutorial_and_Methodology_for_Mapping_Historic_Wetlands.pdf?dl=0</a><br>
<br>
These are all of the maps we are going to georeference from the NY metro region: <a href="https://www.dropbox.com/sh/q73vhjrnj0e1lbf/AADTjbuSbYM7n2JgtWLG-vOya?dl=0" rel="noreferrer" target="_blank">https://www.dropbox.com/sh/q73vhjrnj0e1lbf/AADTjbuSbYM7n2JgtWLG-vOya?dl=0</a><br>
<br>
This is a map RPA created in 2003 that looks at many of the historic wetlands in the NY/NJ Harbor, from a single British survey map: <a href="https://www.dropbox.com/s/pc0p9i6nlvfs1tm/RPA_Historic_TIdelands_NYNJ_Harbor_Estuary.jpg?dl=0" rel="noreferrer" target="_blank">https://www.dropbox.com/s/pc0p9i6nlvfs1tm/RPA_Historic_TIdelands_NYNJ_Harbor_Estuary.jpg?dl=0</a><br>
<br>
And here are some examples of georeferenced maps (Tif): <a href="https://www.dropbox.com/sh/xe0naanoabdtavt/AACiPDiUyGJA6LbrOjIOpqO2a?dl=0" rel="noreferrer" target="_blank">https://www.dropbox.com/sh/xe0naanoabdtavt/AACiPDiUyGJA6LbrOjIOpqO2a?dl=0</a><br>
<br>
In order to create a draft TMS, I uploaded the individually referenced maps as GeoTIFFs into TileMill, combined into a single map, and was able to export a single map in a TMS format.<br>
<br>
However, ideally to make this scalable beyond the New York metro region, we would want to use something like MapWarper to make it easy for others to georeference other geographies or times series.<br>
<br>
Thoughts?<br>
<br>
Thanks! -s<br>

</span><span class="">But that wouldn't work if the maps overlap? Such as maps over the same area but for different time periods.<br>
<br>
I got an instance of TM up and running against OHM, will probably find some issues but is published my code later tonight.<br>

You need to look at what Donal Diamond (IrlJdel) does for the GSGS3906 maps which are individually warped on map warper, but pulled together in a single TMS layer.<br>
<br>

Combined TMS: tms[18]:<a href="http://mapwarper.net/layers/tile/101/{zoom}/{x}/{y}.png" rel="noreferrer" target="_blank">http://mapwarper.net/layers/tile/101/{zoom}/{x}/{y}.png</a><<a href="http://mapwarper.net/layers/tile/101/%7Bzoom%7D/%7Bx%7D/%7By%7D.png" rel="noreferrer" target="_blank">http://mapwarper.net/layers/tile/101/%7Bzoom%7D/%7Bx%7D/%7By%7D.png</a>><br>

3000 maps is a bit of a issue, iD API for custom TMS layer only support one at a time, and I guess that those 3000 maps is overlapping too? For example the HOT TM has one TMS layer for each project, something that wouldn't work in this case.<br>
<br>
I see two possible solutions for this, one is to add the link to each relevant TMS layer in the task description, this would be a lot of manual work. Another and probably better solution is to add all maps to iDs imagery index, currently there is less then 200 maps there, I'm not sure about how much 3000 maps would affect performance... This solution requires that all maps has bounding boxes. Maybe I would need to setup a custom iD instance too...<br>

<span class="">Hi Albin,<br>
I think that's essentially the task, but instead of invoking openstreetmap, the TM would instead point to OHM. Awesome if you can stand up a new instance!<br>
Thanks,<br>

There are two types of people in the world. Those that can extrapolate from incomplete data.<br>

I'm looking into it, shouldn't take much time at all to setup. Just setting up a new TM instance connected to OpenHistoricalMap?<br>

Hi folks –<br>
<br>
</span>I had sent around an email about a month ago about a project at RPA (<a href="http://www.rpa.org" rel="noreferrer" target="_blank">www.rpa.org</a><<a href="http://www.rpa.org" rel="noreferrer" target="_blank">http://www.rpa.org</a>>) to map the historic wetlands of the New York metropolitan region from the 1830’s - 1850’s, as part of our research on climate adaptation. (See email chain below for details).<br>
<span class=""><br>
The project has started to take off. We have had a great response from the community so far – and have partnered with Steven Johnson at TeachOSM and others to shepherd this mapping effort. Through this project, we hope to build out some of the infrastructure that would help the OHM community continue to grow.<br>
<br>
For this project, we will need a Tasking Manager that is connected to OHM. We could build off the TeachOSM TM by overriding the default iD link for each job – or set up an entirely separate TM for OHM. I think the latter may be a better option. Is there other infrastructure OHM needs to move forward that could fit in the scope of this project? (I have a modest amount of funding that I could use to defray some of the cost of development time. Can anyone on this list point me in the direction of someone who would be willing to get an OHM-connected TM up and running?)<br>
<br>
</span><span class="">I look forward to hearing any comments, questions, ideas, suggestions from you about this project as it moves forward – and to gauge your interest in the project as a whole. If you would like to be involved in this project, please feel free to contact either myself (<a href="mailto:sanjay@rpa.org">sanjay@rpa.org</a><mailto:<a href="mailto:sanjay@rpa.org">sanjay@rpa.org</a>>) or Steven (<a href="mailto:sejohnson8@gmail.com">sejohnson8@gmail.com</a><mailto:<a href="mailto:sejohnson8@gmail.com">sejohnson8@gmail.com</a>>).<br>
<br>
