interests

  • areas I have touched in the past 13 years, since I started my MSc research: geographical analysis, visualization, cartography, geographic information systems (GIS), (Java) programming, computational geometry, pattern recognition and data mining, machine learning, agent based systems, optimization, location based services (LBS), (land) surveying, geomatics, software development, user centered design, urban planning, landscape ecology, wildlife ecology, remote sensing, participatory GIS, social networking, writing articles, e-learning,
  • and less so: spatial databases, visual perception and cognition

bio-sketch

  • I am now working at Pontificia Universidad Catolica de Chile (PUC) as coordinator of an SDI for "CEDEUS", which is the Chilean Centre for Urban Sustainable Development : cedeus.cl. Or as they prefer to say here, the Observatorio CEDEUS. At the moment, this is a web-accessible geo-data repository (hello to GeoNode) and there isn't much "observation", but more stuff is planned.
  • Before that, I have been working with Dr. Andrew Hunter at the University of Calgary (CAN), on the PlanYourPlace project from July 2011 until December 2012. Well in fact, we are still working on PlanYourPlace, but a bit less intensive.
  • I took a break from research from October 2010 to June 2011 and went backpacking in Argentina, Chile and Bolivia, to get to know these beautiful countries, and to learn Spanish from scratch.
  • From Sept. 2009 to Sept. 2010 I was within the group of Dr. Andrew Hunter at the University of Calgary (UofC) as a PostDoctoral Fellow developing tools and methods for Movement Analysis (i.e. Home Range analysis) of Grizzly Bears (based on GPS collar data).
  • I also did research as PostDoctoral Fellow in Landscape Ecology and object based image analysis with Dr. Geoffrey J. Hay from Feb 2008 to July 2009 at the UofC.
  • From 2004 until 2007 I did my PhD research on Automated Map Generalization within the GIS Division of the University of Zurich, under supervision of Prof. Dr. Robert Weibel.
  • From 2005 until my travels in October 2010, I was project leader of the JUMP Pilot Project which maintains the free desktop GIS OpenJUMP.

Research Interests

Data enrichment for map generalization

before you start reading this, I like to note that this section needs a rewrite...

My research interests are focusing on the following areas within GISystems & Science and its application:

  1. participatory web platforms for urban planning,
  2. spatial data infrastructures for geographical research,
  3. development of spatial analysis algorithms for landscape and wildlife ecology,
  4. automated cartography & map generalization,
  5. free and open source GIS software developments and adoption in teaching, research, and business.


1. PhD project DEGEN (2004-2007)

OpenJUMP HoRAE screenshot

My PhD project at the University of Zurich covered one part of the DEGEN project - Data Enrichment for automated map GENeralization - that was funded by the Swiss National Science Foundation (SNF). The final thesis was entitled "Enabling Pattern-Aware Automated Map Generalization" (pdf-small; pdf-large), and covered the following topics:

  • perception based pattern recognition approaches for the structural analysis of topographic and categorical (vector) maps
  • cartometrics and map object relations
  • discriminant analysis algorithms for urban structure recognition
  • map generalisation modeling and control: Multi-Agent-Systems, Genetic Algorithms
  • map generalisation and signal processing algorithms: Snakes, TAFUS, Wavelets

The second part of the project was done by Moritz Neun who developed a novel web service for web-based map generalization and GIS-(analysis) called WebGen.

2. PostDoc project PAGEVIS-LD (2008-2009)

These research topics mentioned above are also covered within my project "PAGEVIS-LD - Pattern-Aware GEneralisation and VISualization of Land-use and Land-cover Data", carried out at the University of Calgary (2008-2009).

3. PostDoc project OpenJUMP-HoRAE (2009-2010)

I also gained an interest in GIS application for Landscape Ecology and Animal Movement Analysis. Hence, I was working with Andrew Hunter on topics related to the Foothills Research Institute Grizzly Bear Program to develop GI tools for home range analysis based on GPS collar data. Final result of these R & D project was the [Movement Analysis OpenJUMP HoRAE] toolbox.

4. PostDoc projects PlanYourPlace and AccesoBarrio (2011-2012, 2015-2018)

My latest work on the PlanYourPlace project went into a different direction: the development of a participatory/social web platform to be used in community/urban planning. Our results and efforts on developing the base platform and urban accessibility evaluation tools (WalkYourPlace) are published in papers and workshop contributions - that can be found below. My research in the AccesoBarrio project focuses on developing the existing accessibility webtool a bit further as a planning tool for urban and transportation planners.

5. Other work (2004+)

Most of the developments for my research have been done with Open Source GIS tools and libraries (especially with OpenJUMP GIS; see also below).

Apart from the topics above I also touched other topics in GIS research, such as

  • Urban built-up patterns and their correlation with socio-economic data (supervised student project)
  • Morphologic and vegetation dependent filtering of LIDAR data (supervides student project)
  • Location-Based Services
  • Optimal Xylomigrant placement constrained by mirco-scale traffic behaviour. :o)

Free & Open Source GIS

From 2005 to 2010 I was one of the project administrators of the Jump Pilot Project and developer for OpenJUMP GIS. Own extensions for the free & open source GIS OpenJUMP, which is based on the Java Unified Mapping Plattform (JUMP) by VividSolutions, can be found below.

  • In Oct. 2007 I gave a presentation containing and overview on Free and OpenSource Desktop GIS: "Open Source Desktop GIS Developments – Is OpenJUMP GIS approaching your Desktop?" pdf
  • Based on the previous presentation I created two overview tables on open souce desktop GIS and wrote several articles on the topic (see my publication list above). At OGRS 2009 I also gave a keynote on the development status.
  • Finally in 2010, I had a look on free software that can be used to build Spatial Data Infrastructures (SDIs). The resulting paper we wrote and a talk are availble for for download too: paper, slides of the talk, video.

OpenJUMP GIS Extensions

Over the years I programmed a couple of plugins for OpenJUMP. Lots of my work was directly integrated into the core of OpenJUMP. However, I also produced several separate extensions for JUMP/OpenJUMP like the ones below:

  • Home Range Analysis Toolbox (HoRAE) - see also Movement Analysis (it's actually an own OpenJUMP distribution)
  • Attribute classification and plotting functions - now integrated in OpenJUMP
  • Landscape Pattern Extension - An extension to extract edges, core area, patches, corridors, branches and shortcut areas as described in (Vogt et al. 2007- Ecol. Ind.) but with buffer operations. The extension provides also a set of metrics to describe single polygons and their neighboorhood: e.g. x-centroid, y-centroid, area, perimeter, concavity, elongation, shape index, Schumm's shape index, fractal dimension, MBR orientation, three buffer density indices, R-Index. Download here.
  • Selection Toolbox - now integrated in OpenJUMP
  • Save Image As SVG PlugIn - now integrated in OpenJUMP
  • MapGen Toolbox (download) - conatins a number of map generalization algorithms (mostly for building generalisation), such as (i) Building Spread Narrow Parts, (ii) Enlarge Building to Rectangle, (iii) Square Building Walls, (iv) Eliminate Small Buildings, (v) Eliminate “Points in Line” of Building, (vi) Simplify Building, (vii) Simplify Building to Rectangle, (viii) Change Elongation of Building, (ix) Displace Lines, (x) Line Smoothing Simple Version, (xi) Line Simplify JTS 1.5 Algorithm, (xii) Merge Polygons ... Note, the source code is available on the OpenJUMP project SVN
