AWMC and Pelagios

January 15, 2013 in News, Updates

From our main site:

AWMC is happy to formally join the Pelagios network. Pelagios is networking site whereby linked data for the ancient world is accessible via the common denominator of Pleiades id numbers. These stable identifiers allow many different types of online data – geographic, epigraphic, archaeological, art historical, textual – and metadata to be aggregated into virtual networks linked through place names (and numbers). The potential of this networking is enormous and AWMC is pleased to join with other colleagues already participating. Read more about the AWMC and Pelagios collaboration on the Pelagios blog. One may browse the AWMC information in Pelagios here.


Minor Changes

January 8, 2013 in Updates

We fixed an error where the print box would not always adjust to user input.

In addition, modern layers are now turned off by default, which should help with the application’s loading time.


AWMC API goes live

December 3, 2012 in News, Site Information, Updates

The Ancient World Mapping Center is pleased to announce the rollout of a new application programming interface (API) that allows users to interact directly with the center’s database. The API can be found here and documentation related to the API can be found at the ‘API Documentation’ tab. The API allows the user access to all of the center’s geographical information, both physical and cultural. This would allow the user, for instance, to pull geographic data from the center’s database directly into a standalone mapping project. Just as with Antiquity À-la-carte, the data is released under the terms of the Creative Commons License. AWMC welcomes (and encourages!) user feedback.


Polygon Search updated

November 30, 2012 in Updates

We fixed an error where searching by area did not return full feature information. The search should now be working as intended.


Modern Data

November 14, 2012 in Updates

We have now added modern GIS data (elevation from USGS GTOPO30, all other data from VMAP0 shape files created by GIS-Lab) which allows you to easily visualize changes in geography from antiquity to the present. At the moment we have modern layers for elevation, hill shades, coastlines, inland water, and open water.

For instance, if you are interested in the Po river (ancient Padus/Eridanus), you see the ancient geography as the default view:

By enabling the Modern Open Water layer, you will place the modern data set underneath the ancient one. You can then use the transparency slider on the ancient layer in order to highlight the difference between the two sets, as in the following example:

The link to this particular view is:

http://awmc.unc.edu/awmc/applications/alacarte/?jsonGet={“zoom”:”5″,”center”:”lon=12.181122842056,lat=45.051409735141″,”pids”: []}

Please note that the modern elevation and hill shade layers are offered at a significantly lower resolution than their ancient counterparts, due to our desire to focus our time and resources on ancient geography.


New Features – Linking to Maps Part 3

November 2, 2012 in Updates

We have one additional feature that makes linking to our maps even easier. Under the File menu in the map panel you will find a new option: Map URL.

Clicking on this option will spawn a popup which has a clickable link to the current map state:

In this case the url is:

http://awmc.unc.edu/awmc/applications/alacarte/?jsonGet={“zoom”:”6″,”center”:”lon=26.865381755052,lat=38.848414981353″,”pids”: [{"pid": "550812"},{"pid": "599612"},{"pid": "550893"},{"pid": "550908"},{"pid": "222192"},{"pid": "507469"},{"pid": "550898"},{"pid": "599947"},{"pid": "897849"},{"pid": "550595"},{"pid": "550696"},{"pid": "550497"}]}

If you click on this link, a new window will appear zoomed and centered to your current map view. You can simply cut and paste this URL into your own site, which will allow visitors to interact with any map that you create.

At the moment this only supports features that are in the Pleiades data set, so any customization will be lost (this is due to the fact that the URL generated will certainly become too large if we allow for customization of that kind). We are working on an alternative method for linking to maps using  POST parameters, but for now this is an easy and quick way to generate customized map views for external websites. As usual, please feel free to comment on this functionality, along with any suggestions for improvement.
