How to Use the Atlas and Acknowledgements

The San Diego-Tijuana International Border Area Planning Atlas is designed to help planners, researchers, developers, decision makers, and community members better understand the binational region that is the interface between San Diego and Tijuana. This interface— the International Border Planning Area—is described and analyzed through 15 maps and accompanying essays.

The first essay, "Historical Background of the San Diego-Tijuana Region," provides a brief overview of the historical development of the border planning area. The second essay, "The San Diego-Tijuana International Border Planning Area," describes the border planning area and helps the reader understand the boundaries for the study area as shown in Map 1, "San Diego-Tijuana International Border Planning Area."

Subsequent thematic maps are all accompanied by focused essays. The reader is encouraged to not only view the maps, but to also read the accompanying essays. The essays are interspersed among the maps so that each essay immediately precedes the map or maps that it describes. This arrangement enables the reader to conveniently move back and forth between the paired essays and maps.

Readers will note that there is some repetition of information from essay to essay. This was done in order to provide complete descriptions for each map.

Maps 1, 6, 13, and 15 are all arranged on a single fold out sheet in the atlas. The rest of the maps are printed two to the sheet. In all cases, the descriptive text is followed by the maps.

Each map contains a legend that provides definitions for symbols, colors, and other cartographic representations used. In addition, each map has a listing of data sources used to generate it.

The final section of the atlas titled "Sources and Methods" follows Map 15. It consists of three parts. The first lists printed, manuscript, or electronic sources that were used to write the individual essays of the volume. These sources are arranged according to each map. The second part, "Data and Methodology," describes the overall data used in the project and the methodology used to convert the data into layers that appear in the maps. The third part, "Data Sources," lists the sources that were used to create the thematic data layers used in the different maps of the atlas. The last two parts also indicate the repository where the different data layers are held.
