Geocoding the Murals of El Paso, Texas: An Analysis by Addresses and Zip Codes Sociology 3332/Anthropology 3332 Intro to GIS Project (Graduate student) Final Report Miguel Juárez May 4, 2011 1 Introduction The book Colors on Desert Walls: the Murals of El Paso1 (1997, Texas Western Press) features over 200 murals that range from works painted under the Works-Progress Administration (MPA) in 1938 to Chicano murals painted under the Spaghetti Bowl in 2010. Even today murals are being painted on walls in El Paso. In retrospect, when Colors was published in 1997, Texas Western Press did not see a need to include maps in the book. This, I believe is one of the book’s deficiencies. At the time I did not know whether the TWP had the capacity to create maps or if I as the author, was supposed to provide them—regardless, the topic was not discussed. Another deficiency of the book was that the TWP wanted to produce a coffee table-like book of images of the murals, whereas I wanted to write a social history of murals and mural-making in El Paso. I created several drafts and all met with dislike from the Marcia Daudistel, the acquiring editor at the time who asked me to trim it down and revise it several times. In the end, as a compromise, I decided to interview the artists who had painted the murals and to publish their oral histories and that would comprise the text accompanied by images of the murals created by Cynthia Farah, who was my co-researcher in the creation of this work. I interviewed and transcribed the artists featured in the book and Cindy provided the images. Geo-coding Murals Before beginning the project I searched for other projects that may had done something similar but I did not find anything related to what I sought to do for this project. I did locate an article on the Internet titled: “Philly Chooses GIS to Showcase and Manage its 1 Miguel Juárez, Colors on Desert Walls, the Murals of El Paso (Texas Western Press, 1997). 2 City of Philadelphia Mural Arts Program, Muralfarm.org, http://muralarts.org/muralfarm. Accessed May 4, 2011. 2 Thousands of Murals,” published on 1/7/2009 that documented the City of Philadelphia’s efforts to geocode its murals. The article described a site titled: “Muralfarm.org, an interactive geographic online web application, pictures and detailed information about murals [that] can be searched by artist, theme, date, location, neighborhood, and other key terms. Visitors to Muralfarm.org can tag favorite photographs, save searches, be notified when new murals are added thanks to GeoRSS feeds, and enjoy special features such as viewing the murals in Google Earth and Google Maps. Mural Arts Program staff can easily and efficiently manage information pertaining to each mural through a sophisticated asset management back-end interface. The new site, www.muralfarm.org, will officially launch on January 29, 2009.”2 For the graduate project in the Sociology 3332/Anthropology 3332 class Introduction to GIS class I chose to geo-code murals in El Paso featured in the Colors on Desert Walls book that had addresses where murals had been painted. For murals that had addresses I added their zip codes by looking up the addresses in various Zip Code search engines like the UPS Zip Code finder.3 I added these Zip Codes to the Excel file that coupled with the addresses produced the data to produce this project. It is important to note that not all locations where murals had been painted had addresses. I did embark on locating addresses for various murals using Google Earth, as well as the Internet, but at a certain point this proved to be too laborious, so I limited the number of murals to 200 and included the murals that I felt were important to include. Initially, I created a spreadsheet with various attributes but again after entering data for several days, I chose to capture the data I felt most important like Title, Address, Year Painted, and Creator along with pertinent attributes when possible. Among the different techniques like using x-y coordinates, latitude and longitude, addresses with zip codes provide a means to geo-code, so this is what I utilized for this project. 2 City of Philadelphia Mural Arts Program, Muralfarm.org, http://muralarts.org/muralfarm.

I found difficulty in separating clusters of murals that shared one address and one zip code. There are three clusters of murals in this study that separately share singular addresses: (1) eight murals at the University of Texas all share one address—due to the fact that all buildings share the same university address; (2) forty-three murals at Lincoln Park that are painted on the various columns under what is informally referred to as the Spaghetti Bowl. With the creation of the various freeways spanning the Lincoln Park Community, historical addresses were obliterated and basically all murals now share one address. Another cluster of murals is located at (3) the El Paso Community College Valle Verde Campus and again, all buildings, like the ones at UT El Paso have one address. In the creation of preliminary maps, I tried to include too much information on the various maps and then Dr. Collins suggested I create an Appendix so I could list the murals by location instead--I have done so (see Appendix A). I created one shape file and worked off of it because I found difficult creating separate files using the Open Attributes tool and combining different SQL data because all 4 fields were classified as numerical data. This proved to be effective but then I found that there needed to be consistency in creating the various maps. When I made an edit to improve one map I then had to go back and apply the same edit to all the other maps. In the middle of creating several maps, I found that the “Save As” function was easier than creating an entirely new map. I found it necessary to create a hand-drawn style sheet (like a flow sheet) to plan out how I was going to do the project and to have a place where I could note what fonts I was using for titles and various labels. This style sheet also gave me an overview of my progress and what needed fixing. I also noted the file name for each of the maps. The sheet helped me “visualize” the overall project and complete it. Analysis “What I discovered” The areas with the most murals include: (1) Segundo Barrio/Chihuihuita; (2) Lincoln Park; and (3) Central El Paso. Unbeknownst to the general public, murals are found throughout the city. This was a very labor-intensive project and might have been too ambitious to undertake in one semester. Conclusion I found creating these maps was a very satisfying and exhilarating experience given that I was able to use my old data and in effect, by geo-coding it, make it “new” again. I see great possibilities of utilizing this technology for a myriad of uses—for history, for the analysis of information needs, for tracking population and demographic patterns, and for engaging in social-political issues. 5 I realize that this project could easily have risen to an entirely new level if it could have incorporated additional data, images and indexing, as well as assigning numeral codes to murals and describing each in detail. Or like the Philadelphia project mentioned in the beginning of this essay, this work can live online and work similar to a UCLA product called Hypercities.4 A separate section could feature murals that have been painted over and no longer exist. Yet for this assignment none of this was warranted, although I can see how this project would be the ideal for the merger of community art, socio-political art history, urban history, politics, geo-coding (all areas I am very interested in) and with the analysis of those results and the addition of some theory on the built environment and socio- political factors in the creation of murals and mural making and it could easily become my dissertation. 4 Hypercities, http://hypercities.com/.
