FOREWORD
The geographic data and knowledge collection and dissemination via
authoritative professionals only – characterized as the top-down scheme –
has been shifting in the past few years to the bottom-up scheme, in which
citizens and laymen generate data they later use as information in various
applications and services. This is a new era in the history of human mapping
efforts, mainly in terms of data collection, but also for knowledge
production.
This neogeography revolution is fundamentally transforming how geographic
data are acquired, maintained, analyzed, visualized, and consequently –
used. With today’s technology, availability, access and ease of use there is
a potential of a geographer within everybody.
In view of these changes in the mapping and land surveying domain over
the past few years, Commission 3 has undertaken the mission to prepare this
publication within the framework of FIG, aiming to emphasize the
accessibility, the potential, and the use of crowdsourcing and VGI as a
basic tool for land surveyors and mappers professionals.
During the 2011–2014 and 2015–2018 periods, FIG Commission 3 has
addressed this phenomenon of shifting from the top-down mapping scheme to
the bottom-up one. Its particular focus has been on SIM Infrastructure,
Technical Aspect of SIM, and on Crowdsourcing and VGI.
In this effort, FIG Commission 3 has established valuable collaborations
in an effort to adopt a multi-sector approach, and bring together people
with relevant expertise, such as academics, experts from the public sector
as well as from the private sector, to share experience and knowledge on
crowdsourcing and VGI. FIG Commission 3 cooperates closely with UN-agencies
(UN ECE WPLA, and UN-HABITAT and GLTN), UNESCO, the World Bank, ISPRS and
other sister associations.
This publication integrates the output of research studies done by
Commission 3 working groups and resolutions from the past annual workshops
(Paris 2011, Athens 2012, Skopje 2013, Bologna 2014, Malta 2015, Iasi 2016,
Lisbon 2017 and Napoli 2018).
