[Part 1] Lemos' paper depicts map-making as a socio-political act, an expression of power. Maps themselves are a visual way of presenting geographic information, and have been traditionally controlled by technicians, governments and private companies, but since the advent of interactive online tools, some of the power inherent in map-making has shifted to ordinary people. Interactive tools such as Google Maps, allow the everyday person to experience a new practice of place, as Lemos writes "mapping our moves on the streets allows us to control the space; it is territorialization. […] The use of GPS and other devices for location and location-based services puts the emphasis on control and domination over a territory" (Lemos 2008, p.15). From the perspective of student protesters in London at the end of 2010, the use of an interactive Google map (see and example at: http://www.movements.org/blog/entry/maptivism-in-london), allowed protest organisers to control the flow of digital information between cyberspace and the urban environment. Protesters themselves, those armed with locative media such as smart phones, had access to near real time data superimposed upon street maps relevant to their own position. This allowed protesters to collaborate by providing feedback to organisers or by reacting geographically to reported police location and action.

[Part 2] The act of real time digital mapping and urban annotation by protest movements potentially creates a new dynamic where the distribution of power relative to a location is altered. The ways in which citizens perceive the city and interact with its structure is changed when citizens have access to information about proximity and distance, when they are kept informed of lines of escape from controlled spaces. The act of protesting creates a temporary urban space, changing a location's social meaning. With the use of digital mapping tools a mobile social network is created, one that has the potential to communicate more effectively than the police forces arrayed against them.

Lemos' journal examines the notion that recent mobile innovations have facilitated new and socially focussed communication systems. Locative media is the primary focus of the article and Lemos argues that technology and its relationship with mobility, community and place are creating new forms of 'territorization' - a socio-political act that involves control, surveillance and tracking. The distinction is made that locative media creates new uses for non-virtual space and bridges the gap between the physical and the virtual. This is achieved through augmented reality, mobile information consumption, events and geo-mapping; all which reinforce collaboration and participation among real world communities. Examples of locative media and territorization include CitizenMap, a community focussed web service which utilises Google Maps, Twitter and news sources to identify and detail environmental incidents throughout Hong Kong and the South China region. Sukey, an anti-police kettling application is another example of locative media, this service aims to improve communications throughout demonstrations by feeding police tactics and information from an assortment of data sources such as Twitter, Google Maps, Flickr and directly aggregating it to mobile / SMS enabled devices (Sukey, 2011). What Lemos fails to expand on in the journal is the technical and participatory expectations required for the services to be successful. Without regular and active participation these services add little or no value to the community or the cause.
