This page lists, links to, and briefly describes files developed for the purposes of teaching social studies using geospatial tools (primarily Google Earth and My World GIS). Most, but not all, of these files have been developed at Lehigh University by students in the Teaching and Learning with Geospatial Tools (TLT 368) course taught by Dr. Hammond.

circa 1270-1520: European Explorers
Google Earth file first composed by Tom Hammond, 2008: European explorers ver02.kmz.
Description: Presents overview of European 'voyages of discovery', framing them in a search for water routes to Asia. Uses Jamestown and the instructions to the settlers to invite a driving question. (For example: Why are these instructions so specific? Why specify taking the northwest branch of a river? And what is meant by 'the other sea'?) It then moves back to discuss European contact with east Asia, using Marco Polo (but the Crusades would also be a logical point of reference). Traces efforts by Genoa, Portugal, and then Spain to locate water routes to Asia as a way of addressing the driving question (i.e., the Portuguese had found a water route south and east; the Spanish had found a route west and south; the English and others hoped to find a route west and north).
This file is pretty approximate work and contains much room for improvement! Does not include other voyages commonly included in the K-12 curriculum: Spanish intra-continental expeditions (e.g. Cortez, Pizarro, Balboa, de Leon, et al.), French explorers (Champlain, Marquette, et al.), other English expeditions (Cabot, Hudson, et al.). Other authors are invited to add these, or teachers could have their students add these as extensions to the existing file.

Jamestown: ArcGIS Online map created by Tom Hammond in 2023, drawing upon materials from the Virtual Jamestown Project: indian_groups.kmz, along with various sources for overlays of historical maps.
More comprehensive view: Google Earth created by Tom Hammond, 2012: British_colonies_in_North_America_ver02.kmz. Note that this overlay links to a file created by the Virginia Center for Digital History, Virtual Jamestown Project: indian_groups.kmz, along with various sources for overlays of historical maps._ver02.kmz.
SmartNotebook file to accompany Google Earth overlay (contains static versions of historical maps, plus other information): early_colonies_notebook_ver01.notebook.
Description:
- Expands upon VCDH's concept of Jamestown viewed from "inside the longhouse" -- rather than view the English settlement in a vacuum, this overlay shows the inverse: the Native American settlements in the region. For the English, it was a New World; for the Chesapeake-area residents, it was a familiar territory. For more information about the file, see www.virtualjamestown.org/ge_indian_groups.html
- Accompanying documents and data, including the 1595 map by John White, 1608 map by John Smith, and locations for the archaeological Jamestown and a reconstructed Fort Raleigh at Roanoke, plus several New England colonies (Plymouth, but also predecessors at Cuttyhunk and Popham).

Also includes portraits of John and Moses Brown and the Brown University logo. Second page of file has info on Brown family for discussion of role of slavery (or profits from slave trade) in building this institution.
July 24, 1776: Signers of the Declaration of Independence
ArcGIS Online map by Julie Oltman & Tom Hammond; StoryMap by Tom Hammond
Description: Uses colony boundaries from 1763, population data from 1770, and data about the signers of the Declaration from archives.gov (https://www.archives.gov/founding-docs/signers-factsheet); slave ownership data from https://www.mrheintz.com/how-many-signers-of-the-declaration-of-independence-owned-slaves.html

My World GIS file created by Tom Hammond, 2011: Jewish populations circa Holocaust ver01a.m3vz
ArcGIS.com map created by Tom Hammond, 2016; additional border layers from Julie Oltman
Description: Uses data from Yad Vashem to show pre-war Jewish populations and number of victims of the Holocaust for selected countries. Allows students to grasp the full extent of the Holocaust (e.g., it includes countries such as Tunisia and Libya, which were then under Italian control), and to note discrepancies in patterns (e.g., percentage of Jews killed in Germany vs. Poland; the strong contrasts within the southeastern Europe such as between Bulgaria and Greece).strong contrasts within the southeastern Europe such as between Bulgaria and Greece). Note: The map uses contemporary borders. Borders for 1938 and 1945 are included as a reference; users should keep in mind that the borders were in flux at this time.
