PLOS: Social sensing of urban land use based on analysis of Twitter users’ mobility patterns. “A number of recent studies showed that digital footprints around built environments, such as geo-located tweets, are promising data sources for characterizing urban land use. However, challenges for achieving this purpose exist due to the volume and unstructured nature of geo-located social media. Previous studies focused on analyzing Twitter data collectively resulting in coarse resolution maps of urban land use. We argue that the complex spatial structure of a large collection of tweets, when viewed through the lens of individual-level human mobility patterns, can be simplified to a series of key locations for each user, which could be used to characterize urban land use at a higher spatial resolution.”

The Next Web: Snapchat launches a design studio for custom geofilters. “Snapchat introduced the ability to let you create your own Geofilters – effects that are only available in specific physical locations – early last year, but you had to be familiar with design tools like Photoshop or Illustrator in order to make anything decent. Fret no more: you can now create your own filters from scratch right from your browser.”
The CAMEL Lab at the University of Chicago has launched a new online data repository. “The Center for Ancient Middle Eastern Landscapes (CAMEL Lab) at the Oriental Institute of the University of Chicago would like to announce that a substantial subset of its digital holdings of maps and geospatial data are now available for online public search and download…. CAMEL’s database includes over 20,000 unique objects of spatial data that relate to the archaeology, anthropology, and history of the Middle East, almost 9000 of which are now publicly available. “
