Open History Map Exploration

The OHMEC project is a free, open-source geography project, with a goal of representing all historical indigenous lands and political boundaries in a unified database. The uniqueness of OHMEC is its ability to represent these lands and boundaries on any date, as well as being able to show the dynamic changes in lands and boundaries from any point in history to the present. It is very much a work in progress. This early demonstration shows a rendering of historical data in Mesoamerica using Leaflet to display geographical features from the database, overlaid on top of a modern map.

The OHMEC project is being developed openly in a Github repository. Participation is welcome, see that repo for more information on the management of the project. Also see this slidedeck for more insight into the project. A specification of the extended GeoJSON format that underpins the historical database is provided here. For information or any questions, please use ohmec.contact@gmail.com.

This Mesoamerican study focuses on the time period between 1800 BC and 1600, about 100 years after the first Western incursion into the hemisphere. The geographical arena of the study is roughly the modern Mexico and Central American regions. Clearly the farther back into history the data is, the lower the fidelity and confidence. That said, the Mesoamerican region is rich with advanced civilizations that left many architectural and written records. In addition, there were many eyewitnesses to the stark encounters of the early Spanish entrants into the homeland of the Aztec, Mayan and other existing Mesoamerican civilizations.

A few closer focus links are shown here:
