Projecting tabular data onto maps helps in recognizing unanticipated situations which, when noticed,
call for closer examination.
Through considering geographical (spatial) factors, the analysis becomes finer and more precise,
increasing the likelihood that ensuing strategies will be more pertinent.
More flexible assistance can be provided in prospective planning at multiple levels or units of analysis:
national, regional, provincial/ district, and local (De Grauwe, 2002).
Expanded holistic representation and exploration of the contexts of schooling, which are otherwise very
difficult to contemplate in educational planning and management through the direct and dynamic use of
multiple sources of influential data, such as those found in census, transportation, utilities, health care,
land use, and agricultural databases.
Increased public appeal and utility;
Extensive control of scale of complexity, and flexibility in how much data are displayed or explored at a
given time, with changes in unit of analysis virtually limitless and immediate; and
Dynamic ability to facilitate ‘what if’ analysis, exploratory inquiry, and creation of planning and
management scenarios (Hite and Hite, 2004)
2. Second Part: Public Participation Geographic Information System (PPGIS): An overview
A public participation geographic information system (PPGIS) is meant to bring the academic practices
of GIS and mapping to the local level in order to promote knowledge production by local and non-
governmental groups. The idea behind PPGIS is empowerment and inclusion of marginalized populations, who
have little voice in the public arena, through geographic technology education and participation. PPGIS uses
and produces digital maps, satellite imagery, sketch maps, and many other spatial and visual tools, to change
geographic involvement and awareness on a local level. The term was coined in 1996 at the meetings of
the National Center for Geographic Information and Analysis (NCGIA) (Schuurman, 2008).
2.1 PPGIS for Educational Planning:
PPGIS, which attempts to create and facilitate democratically oriented GIS use in community-based
decision-making, has the potential to influence educational planning positively in a number of ways. Among
other benefits, PPGIS provides the lens through which the substantial challenge of the decentralized-centralized
interplay in planning can be more effectively conceptualized and facilitated.
PPGIS emerged in the late 1980s as a result of democratically oriented socio-political concerns that the
early adopters of GIS were national ministries, military operations, and intelligence contexts (Pickles, 1995;
Goodchild, 2006). Since PPGIS evolved as an effort to enable democratic participation in creating and using
GIS, the definitions of public and participation have been central to its vision (Schlossberg and Shuford, 2005;
Elwood, 2006, 2008; Ghose, 2007). Consequently, significant effort has been made to develop textured and
creative ways of conceptualizing, thinking about, and identifying what specific public should be included, and
at what particular levels of participation. Educational planning can benefit from a serious review and evaluation
of these PPGIS efforts.
