Abstract
Many rural communities are facing the problem of overexploitation of natural resources. A solution
to this problem is possible only when all stakeholders understand the need for it sufficiently and
participate voluntarily. Participatory GIS (PGIS) helps in this process by facilitating better
visualization. However, the technical difficulties associated with these systems may marginalize the
less-educated sections of the community. This and other problems of PGIS can be solved by
simplifying GIS so that it can be used by villagers without much technical assistance from outside
experts. While there have recently been some efforts in this direction, GIS that would provide this
kind of simplified functionality are still rudimentary. Development and field trials of one such PGIS
solution is described.

1. Introduction:
Natural resources of many rural communities are facing the problem of overexploitation over last
few decades and their sustainable management has become an important issue for ensuring
livelihoods of villagers. A solution to this problem is possible only when all stakeholders
understand the need for it sufficiently and participate voluntarily. Participatory GIS (PGIS) helps in
this process by facilitating better visualization and easier understanding of the complex issues
involved (Geertman, 2002; Vajjhala, 2005; Jankowski, 2009; Kolagani et al, 2012).
There are however several problems that need to be overcome before PGIS can deliver all the
intended benefits. The technical difficulties associated with using PGIS may marginalize the less-
educated sections of community who can not cope with such difficulties (Chambers, 2005;
Chambers, 2008; Sieber, 2006). They may need technical assistance from experts outside the
community to use PGIS, which in turn may undermine their creativity and sense of ownership over
the decision making process (Nyerges et al., 2006). These systems then may end up as data-
collection instruments for decision-makers from outside the community and get rarely used from
within the community (Rambaldi et al., 2002).
Many of these problems can be solved by simplifying GIS so that it can be used by villagers
without much technical assistance from outside experts. While there have recently been some
efforts in this direction, GIS that would provide this kind of simplified functionality are still
rudimentary (Voinov and Costanza, 1999; Voinov and Bousquet, 2010; Eckman et al., 2010).
Development and field trials of one such PGIS solution is described in the following sections.
2. An open source Quantum GIS based PGIS solution:
Open Source Quantum GIS (http://www.qgis.org) based PGIS solution, 'villageQGIS', was
developed for use by villagers to carry out accurate mapping and management of their village
resources.

2. 2.1. Gathering location and attribute data using GPS and questionnaires:
Villagers gather spatial location data and attribute data of the wells, farms and other natural
resources ('features') of their village using Global Positioning System (GPS) and questionnaires.
Village youth and others with basic literacy can gather such data quickly and accurately (fig. 1).
GPS is used for acquiring spatial location data about these features. GPS is a low-cost, accurate and
easy-to-use technology that can be used by villagers themselves. It costs about $100 per piece and
has an accuracy of about 3 meters. Spatial data of point features, such as wells, can be collected as
point data by the GPS. Spatial data of line and polygon features, such as streams and farms, can be
collected as tracks by the GPS. However, it requires the user not to deviate physically from the line
or polygon boundary while mapping it in the field. This can be quite difficult due to presence of
thorny bushes and other obstacles in the field. Hence, it is better if line and polygon features are
mapped as points by the GPS and joined later semi-automatically by the GIS software. While GPS
units do provide a route option to join these points within the GPS itself, its user interface is quite
difficult for usage by a villager, compared to that of just clicking one button to store a point.

Questionnaires are used for acquiring attribute data of these features, such as their past and present
status, and for continuously monitoring their status into the future.
2.2. Creating GIS maps from GPS and questionnaire data:
GIS software is needed to convert location data of village features into a map and to tag these with
their attribute data. The GPS data of points representing various point, line and polygon features
need to be imported into the GIS software and then joined manually, in the same order as they occur
in the questionnaire, into various features. The attribute data in the questionnaires then needs to be
tagged to these features.
Commercial GIS software is too costly for use by villagers. In contrast, open source GIS software
such as Quantum GIS can be used freely. However, both commercial and open source GIS software
are difficult and time consuming to use by even educated villages and need substantial amount of
user training. As the steps required are quite difficult to follow, it necessitates involvement of a
remotely located city-based GIS professional, taking control away of the mapping process from the
villagers and making it less participatory and less useful.
Open source GIS software makes it possible to modify it substantially to simplify its user interface
for use by villagers. Open source Quantum GIS software was simplified into a PGIS solution,
'villageQGIS', to make it possible for villagers, such as school children (fig. 2), to create GIS maps

3. from GPS and questionnaire data. The GPS points can be directly imported into the 'villageQGIS'
software which connects them semi-automatically into GIS features and tags them with attribute
data as specified by the user through GUI forms (figs. 3 and 4).

2.3. Using GIS maps for spatial analysis:
An easy-to-use interface was provided for use by a majority of the villagers to view in various
simple formats the complex data gathered to produce these GIS maps of their village resources (fig.
5). Such an easy tool makes it possible for them to spatially analyze and visualize impact of various
alternatives and participate effectively in the decision making process. The pre-defined list of views
can be expanded by creating and adding custom views as per field requirements (fig. 6).

3. Field trials:
The number of mouse clicks a user has to perform for creating maps was substantially reduced in
villageQGIS software. For example, a certain task that takes 17 clicks when using Quantum GIS
software takes only 3 clicks when using villageQGIS (fig. 7).
For an objective assessment of relative ease-of-use of 'villageQGIS' and Quantum GIS softwares,
field trials were carried out. Six groups, with three members each, were randomly selected from the
target audience of school children in two rural government schools, Kallur and Mangalampeta, of
Chittoor district, Andhra Pradesh state, INDIA. Three of these groups were asked to use
(unmodified) Quantum GIS software where as the other three groups were asked to use

4. villageQGIS software. All groups were given the same task of producing GIS maps from the same
GPS and questionnaire data sets. Following parameters were monitored:
• time taken to train these groups in creating GIS maps
• time taken to create maps
• number of maps produced
• accuracy of maps produced, based on deviation from an ideal map
Fig. 7: Clicks involved Fig. 8: Map creation time: villageQGIS and QGIS
Overall, it was found that 'villageQGIS' software was substantially easier than Quantum GIS
software. For example, ratio of time taken to produce maps was at least halved when using
villageQGIS software (fig. 8), when other parameters were held fixed at:
• training time: 1 hour
• number of maps: 1
• accuracy of maps: 60%
As the desired accuracy of maps produced increased, the relative advantage of villageQGIS over
Quantum GIS further increased.
4. Conclusions:
Open Source Quantum GIS based PGIS solution, 'villageQGIS', was developed for use by villagers
to carry out accurate mapping and management of their village resources. Field trials were carried
out to measure ease-of-use of the 'villageQGIS' solution in creating GIS maps from GPS and
questionnaire data. Overall, it was found that 'villageQGIS' software was substantially easier than
Quantum GIS software.
