Survey of Palestine – Zionist Land Ownership, 1930.

Digitized from an original British Mandate-era map created for the 1930 Survey of Palestine and covered into ArcGIS format. One of the immediate benefits of digitizing historic data is that it allows for relatively easy analysis of data that was previously absent or left to estimation and/or speculation. For example, using the digitized data from the original 1930s map, it is possible to now have a better sense of the total amount of land under the various Zionist organizations in 1930. Total land holdings in square kilometers by group can be quickly calculated using GIS.

Furthermore, it is possible to gain a sense of how patterns of Zionist land purchase and how this data relates to other population surveys of the time.By digitizing population statistics for Palestinian Arab villages in 1931, presented in Walid Khalidi’s “All That Remains: The Palestinian Villages Occupied and Depopulated by Israel in 1948”, the relationship between Zionist land purchase and Palestinian Arab population density can be better understood. As the following map indicates, Zionist land ownership occurred largely in areas without Palestinian Arab populations; however, in some areas Zionist landownership coincided with sizable Palestinian Arab villages and future research into the historical nature of Jewish-Arab relations in these areas may be warranted.

Map: Number of 1930 Palestinian Villages Located in 1931 Zionist Landholdings
The previous map uses a .5km buffer on the location of 1930 Palestinian villages in order to create a reasonable extent for the village area. An intersect between these buffered points and the 1931 Zionist land holding data returns a raw count of the number of 1930 Palestinian villages that were located within 1931 Zionist land holdings. The following map utilizes a similar buffer and intersect technique in order to offer some insights into the number of Palestinian villagers residing in Zionist land holdings. In both instances, these numbers should be seen as rough indicators since village dimensions could reasonable extend less or beyond the systematic .5km buffer applied.

The Geographic Scope of Occupy Wall Street
Occupy Wall Street_500x300
As the Occupy Wall Street demonstrations in New York City gained national and international attention, solidarity groups throughout the United States and around the world quickly formed. Some of these groups (e.g. Occupy Oakland) would rival Occupy Wall Street in terms of size and media coverage while numerous smaller groups formed with far less participants and little media coverage.

The map attempts to demonstrate the geographic spread of Occupy Wall Street during its first six weeks of activity. Data for the Occupy Wall Street (OWS) groups was collected from a combination of media reports, OWS organizing sites (e.g. Facebook, Move-On) and other websites (e.g. Wikipedia). This data was then combined with existing GIS data from ESRI as well as new data created by geocoding those often smaller cities and towns not included in the existing GIS data sets.

Reasonable efforts were made to ensure that groups included in this data set, whether on-the-ground, virtual or a combination of the two, were active and existed between September 17, 2011 and November 1, 2011. This was done through a cursory search of media and web resources and focused on establishing organizational activity or sustained actions over multiple days. Consequently, some OWS groups may not be included in the data set because there was insufficient evidence to indicate activity beyond publicizing the group.

Mobile Giving: Development, Activism or Slacktivism?
Prezi presentation that examines the phenomenon of donations via text messaging and explores whether such small scale, ephemeral donations constitute a form of social activism, a mechanism for sustainable economic development or, as some critics contend, is simply another form of digital slacktivism.In the future, this Prezi will include the explanatory material normally delivered through an in-person presentation; however, it is included in its current form as an example of data visualization in multi-media presentation format.
