OpenLayers is down

April 3, 2014 in Antiquity À-la-carte, Benthos, Site Information

It appears that OpenLayers API is down at the moment, causing all of our mapping applications to be inaccessible. We are building a local version of the code library now to ensure that this problem will not happen again, and will post an update here when that task is finished.

New Public Map Tiles and Antiquity À-la-carte 3.0 Beta

February 3, 2014 in Antiquity À-la-carte, API, Benthos, E-resource, Interest, News, Pleiades Project, Site Information

All layers

The Base Map tiles with road overlays

The AWMC is proud to announce the release of a series of geographically accurate, publicly accessible map tiles (http://awmc.unc.edu/wordpress/tiles/ ), suitable for use in nearly any web mapping application or GIS software suite. These tiles are hosted on Mapbox servers courtesy of ISAW, and are created by Ryan Horne from AWMC data produced by Richard TalbertJeffrey Becker, Ryan Horne, Ross Twele, Audrey JoRay Belanger, Steve Burges, Luke Hagemann, Ashley Lee, and others.

Offering the first (and at the time of this writing, only) geographically accurate base map of the ancient world, the AWMC tiles conform to the broad periodization presented in the Barrington Atlas, with different selectable water levels for the Archaic, Classical, Hellenistic, Roman, and Late Antique Periods. In addition, we also model inland water, rivers, and other geographical features as they appeared in antiquity. The base tiles are culturally agnostic, allowing them to be used to represent the physical environment of nearly any ancient society in the Mediterranean world. In addition to the base map and geographical tiles we also present the Roman road network, generally following the Barrington Atlas with additional work by the AWMC. Like all of our other electronic offerings, our new tiles are released under the Creative Commons Attribution-NonCommercial 3.0 Unported (CC BY-NC 3.0) license and remain absolutely free for personal, academic, and non-commercial use.

For guidelines on how to use the tiles in an application, please visit http://awmc.unc.edu/wordpress/tiles/map-tile-information. These tiles are a “living” data set, and will be constantly refined to reflect the ongoing work of the AWMC. We welcome feedback on any aspect of this work and we encourage the community to suggest enhancements, fixes, or any other comments on our dedicated site.

You can see the tiles in action in our API (see, for example, the Urban Area of Rome), the new Beta Version of Antiquity à la Carte 3.0, and at the Pleiades Project.

Along with our tiles, The Ancient World Mapping Center is also releasing a beta version of Antiquity à la Carte 3.0 (http://awmc.unc.edu/awmc/applications/carte-transitional/). The application, engineered by Ryan Horne, builds upon the two previous iterations of À-la-carte, which appeared in Spring 2012 and October of the same year.  Continuing to draw upon the work of the Ancient World Mapping Center and the Pleiades Project, the updated version will incorporate the new AWMC Mapping tiles, along with the expanded features first introduced in v. 2.0. Until the beta version is stable with all of the previous functionality enabled, À-la-carte version 2.0 will remain operational at http://awmc.unc.edu/awmc/applications/alacarte/ . In the meantime, we welcome any feedback on the beta version as we endeavor to create an application that is useful to the ancient world community. We are particularly excited that our new tiles allow us to feature modern data alongside our ancient offerings, which will open many new possibilities and applications for À-la-carte.

Registration Questions

August 8, 2013 in Site Information

We have received several queries about registration for the site and its effect on application functionality. User registration is for WordPress portions of the website only (i.e. commenting on posts, creating groups, increased interaction with the blog, etc) and was implemented to cut down on spam and bot attacks against the server.

Registration has no effect on our applications, the API, or the free download of our data, as none of these applications have the ability to distinguish between an anonymous and a registered user. These applications will always have the same basic functionality for anyone that uses our site.

For those wishing to register and interact with the blog portions of the site, registration will be enabled after August 19th.

AWMC Accuracy Assessments in Pleiades

June 10, 2013 in Interest, Pleiades Project, Site Information

in0006AWMC’s partners at the Pleiades Project have created a range of accuracy assessments related to geographic content derived from the Barrington Atlas of the Greek and Roman World. These accuracy assessments are tailored to the scale and project of the BAtlas and will be of great use to AWMC and its database editing efforts, particularly with respect to physical geography derived from the BAtlas (coastline, rivers, islands, mountains, etc.). The ratings relate to the positional accuracy of data; positional accuracy in GIS terms is a quantifiable value and represents either the positional difference between two geospatial layers of information or between the geospatial layer itself and reality.

Temporary New User Registration Suspension

June 2, 2013 in News, Site Information

As the center will be operating on reduced staffing this summer (and the perennial problem of spam  remain), new registrations over the web are temporarily disabled. All applications (À-la-carte, Benthos, etc.) will function normally. We will once again allow web registrations at the start of the fall 2013 semester. If you wish to be added as a site user in the interim, please e-mail us directly. As always, you do not have to register at all to use the applications or to access our data at  http://awmc.unc.edu/awmc/map_data/ and http://awmc.unc.edu/api/ .

Introducing Benthos

February 15, 2013 in Benthos, Interest, News, Site Information

benthos1AWMC has launched a Beta version of its new project, Benthos: Digital Atlas of Ancient Waters. This project aims to map not only the physical geography of ancient Mediterranean waters, but also to map cultural and historical information related to transportation, communication, and commerce. The initial sample includes data for Mediterranean ports, shipwrecks, and a preliminary attempt at creating network maps for point-of-origin for some elements of commercial wares that were included in the cargo of sunken ships. AWMC feels that a platform such as Benthos has great potential both as a standalone application, but that its value is increased greatly by interfacing with other cognate projects already online. AWMC welcomes community feedback on this new project, as well as inquiries from potential collaborators and data partners.
