As part of my dissertation research, I created a series of predictive models for precolumbian sites in Grenada, from 2015-2019. There are two different types of models -- those predictive of potential archaeological sites in general (2017 map below) and those predictive of settlement time period. The latter is especially useful for sites that are known but unstudied. The 2018 model for Grenada remains the most accurate for settlement period, whereas the 2019 model expanded the idea through the Grenadines and St. Vincent. See Hanna (2018) for an explanation of the Grenada model, and Hanna and Giovas (2019) for a full explanation of this model. For the inventory of sites in Grenada, see the ASIG here.
