This was an invited presentation to the University of Alberta's Human Geography and Planning 100 class. As the title implies, I provided a brief overview of GeoWeb concepts, tools and provided an overview of the maps I found most interesting in the past couple of months.
3. Overview
• Map Concepts
• Place
• GIS & PPGIS
• GeoWeb and other related ideas
• Tools (for making maps)
• The Big 2
• FOSS
• Applications (more maps)
• A bunch of pretty maps
7. Understanding of Place
There was a path in the woods there, and we call that
Moonies run because our teacher, Mr. Moonie, lived
right there. My friend played guitar and I played
guitar, and we used to take our amps, carry our amps
across back and forth across the river. At this point
here right in the middle of the bridge was we deemed
that as perfectly half way, so we would say, „Okay, I‟ll
meet you on the bridge‟. But yeah, I spent a lot of time
down there, in Gold Bar.

8. What is „place‟?
Place is defined as being comprised of three
dimensions (after Relph, 1976):
1. Observable activities that occur in relation
to the location;
2. The meanings that are created by a
person in that location, and;
3. The physical features that comprise the
location‟s concrete or tangible attributes.
9. Situating citizens:
Who is a „place‟ expert?
"Given a large enough beta-tester and codeveloper base, almost every problem will
be characterized quickly and the fix will be
obvious to someone."
Eric Raymond, The Cathedral and the Bazaar, 1999
12. Geographic Information
Systems (GIS)
“A geographic information system (GIS)
integrates hardware, software, and data for
capturing, managing, analyzing, and displaying all
forms of geographically referenced information.”
From: www.ESRI.com
13. PPGIS the early years…
A practice where GIS technology and methods
are used in support of public participation and
decision making in a number of domain
applications (Sieber, 2000).
• Top down & authority driven
• NOT collaborative
• Concerned with problems defined by
authorities
• Stakeholders are to be mined for data
14. GeoWeb
Location Based Data + Abstract Information =
Geographic World Wide Web AKA GeoWeb
Underpinned by:
Global Positioning Systems
Application Programming Interface
Volunteered Geographic
Information
Neogreography
22. OSM
A collaborative project to create a free
editable map of the world. Two major driving
forces behind the establishment and growth
of OSM have been restrictions on use or
availability of map information across much
of the world and the advent of inexpensive
portable satellite navigation devices.

28. FOSS Geo Stack
Data Source (Open Data / OSM)
+
{Data Base (PostGIS)}
+
Visualization Tools (QGIS + TileMill)
+
Map Server (MapBox)
Or
PHP Tile Server & Leaflet
Lynch was perhaps one of the first to use crowdsourced data in his research. He compiled mental maps of Boston, New York and Jersy City that were derived from interviews with people who lived within those cities. This could represent the first PPGIS
Thematic clusters around:Sports and recreation activitiesActivity routesImpressions of placeMemories of placeSpecial placesNotions of power relative to place
Themes such as:IsolationGetting away from it allConnecting with peopleDeeply personal and varied.
The combination of these plus other emerging location based technologies will set the stage for a digital infrastructure that will define, in part, a new way of making places that goes beyond check-ins and maps that locate businesses and restaurant reviews.These data will be crowdsoucred and verified by …. The crowd.
