title: Digging into Early Colonial Mexico Historical Gazetteer

description: The DECM Historical Gazetteer is a digital gazetteer of historical places in Mexico available in different formats and built from detailed research. This includes a 16th century version (The DECM 16th Century Gazetteer) with the toponyms mentioned in primary sources including the Relaciones Geográficas (1577-1585) and the Suma de Visitas de los Pueblos de la Nueva España (1548-1550), as well as information on the political, religious and administrative units of the Viceroyalty of New Spain. The gazetteer is composed of 71 main files with geographic information of colonial provinces, alcaldias, corregimientos, diocesis, among many others, as well as thousands of historical cities, towns, villages, and other places. This is integrated in an interoperable model containing thousands of historical locations with alternative spelling place-name variations. The dataset also includes 30 tables with additional historical information related to toponyms, languages, repositories, maps, etc.There are two versions of the DECM Historical Gazetteer: 1) The DECM Gazetteer, and 2) The DECM_16thC_Gazetteer.This is the DECM Gazetteer and this version includes all the researched historical toponyms contained in primary and secondary sources. The information is organised by RG volume. It also includes layers and tables of historical information digitised and/or created by the project from secondary sources.This set is composed by GIS shapefiles & Linked Places format information with: a) all toponyms with coordinates, mentioned and disambiguated from the primary sources (13 volumes) and secondary sources (3 volumes); b) 30 geographical layers of additional historical information derived from secondary sources; c) 32 tables with other important historical information related to the RGs; and d) the DECM Gazetteer Registry.<b>Content</b><pre><code>1.
