My interests in openstreetmap
Starting from the idea to support Openstreetmap and to help out the creation adding of data to add data to get buildings within certain regions, I discovered how many different things are possible to discover in OSM and I got fascinated by the options of the geospatial data and the data analysis. It is exciting to see how much interesting data in OSM is left to explore with tools, languages - even with the possibility to find 3D data of buildings in OSM. We could also explore OSM with these various languages - like Perl, PHP, Python. Below i show some of the options and aproaches - working with different options such as query OSM data with the Overpass API, OSMOSIS - working with data-formats in XML and JSON and lots of others more. Finally i hope you are inspired to go forth and discover interesting findings in the depths of OSM with your language of choice and with tools that are incredible to use.
Open Source-Communities-insights into the Bazaar-model of software engineering
towards a Better Understanding of Large Scale Network of innnovation .... and production.
if we admit that innovation is about creating meaning and purposeful action; if we further admit that innovation has got a social basis that it is inherently social we have to have a look at the internet. To understand the social basis of innovation and technology development we have to look at the OpenSoure model of innovation.
i was impressed by the book Cathedral and the Bazaar: Musings on Linux and Open Source by an Accidental Revolutionary abbreviated CatB the essay and later a book, by Eric S. Raymond on software engineering methods, based on his observations of the Linux kernel development process and his experiences managing an open source project, fetchmail. My interest in open-source-research is motivated by various insights: i think it is important to examine the barriers and the struggle between top-down and bottom-up design - like Raymonds essay showed with his insights into the new model of development - this first insights and observations were continued by the open source research-group which is organized at the MIT-Ressource https://flosshub.org/biblio

My interests in openstreetmap
- all things regarding the Work with the planetfile Sternchen (*).
- using various tools and language
- Perl, PHP, Python, and XML,
- using various tools and language
- transform data out of German osm-pbf-files -
- straightforward from files that
aimed is to transform data out of German osm-pbf-files - in order to get the data (not to creat maps again) see the source (s)= http://download.geofabrik.de/europe/germany.html ranging form 10 MB (Bremen) to 390 MB (Nordrhein Westfalen) the osm.pbf-files are not too big; Question: which method is the best - the most appropiate? - to store the results in a mysql-db or just have big calc-sheets (with csv-data)
- only straightforward from files that - no backimport of data to OSM from a .csv file
i want to gather data from .o5m & pbf file - several ways are possible: working with the POI out of the OSM-File - and to hold them on a dayly updated version: in other words - i want to keep them updqated - day by day. Well i guess that i can do that with osmfilter and osmconvert - but there are probably better ways to do it:
- PostGis as a solution for getting a database populated by osm2pgsql or osmconvert /-filter to create csv-sheets: curve is to steep; Note: i not only want to have
- POIS from the OSM-File are interesting - but there is more...
- MySQL of course is a good tool to use - for what i am having in mind
Technologically and methodolocically i am inspired by Martijn van Exel approach to keep an overview on the US-bridges note; he looks for the bridges in the US ( http://oegeo.wordpress.com/2012/03/06/a-self-updating-openstreetmap-database-of-us-bridges-a-step-by-step-guide/ ) There are about 125,000 of them – So on the scale of OpenStreetMap data it’s a really small subset. In terms of the tools and processes needed, the task seems easy enough, and as long as you are satisfied with a one-off solution, it really is. You would need only four things:
- A planet file
- A boundary polygon for the United States
- A PostGIS database loaded with the osmosis snapshot schema and the linestring extension osmosis, the OpenStreetMap ETL swiss army tool.
That, and a single well-placed osmosis command:... [...] end of cit.. source cf http://oegeo.wordpress.com/2012/03/06/a-self-updating-openstreetmap-database-of-us-bridges-a-step-by-step-guide/ ) note: the Martjin wants to get the data of all bridges in the US that are mapped in OpenStreetMap in a PostGIS database that stays as up-to-date as possible, reflecting all the latest changes."
Intention:
new o the technique of OpenStreetMap: working with the languages like PHP / Perl and of course Python i am working on the API-endpoint with requests ...
osmconvert and osmfilter
Overpass-API and Overpass-Turbo-API
working on the planet file
- at the API-Endpoint with PHP, Perl, Python
- PostGIS and of course osmosis - the OpenStreetMap - swiss army tool.

Open Source-Communities - insights into the Bazaar-model of software engineering
i was impressed by the book Cathedral and the Bazaar: Musings on Linux and Open Source by an Accidental Revolutionary abbreviated CatB the essay and later a book, by Eric S.

My interest in open-source-research is motivated by various insights: i think it is important to examine the barriers and the struggle between top-down and bottom-up design - likr Raymonds essay showed with his insights into the new model of development - this first insights and observations were continued by the open source research-group which is organized at the MIT-Ressource https://flosshub.org/biblio
Some interesting articles, ideas and concepts were linked at the subsite: Organisation im Wandel: die OpenSource-Forschung und Perspektiven
- discourse of universe / universe of discourse (G.H.Mead)
- Cathedral or Bazaar - Eric Raymond
- Network of innovation - Illka Tuomi
- Community of Practice CoP Lave & Wenger and furthermore...- there are even more interesting concepts:
LPP: Building upon Lave and Wenger's theory of legitimate peripheral participation (LPP), this paper offers a longitudinal investigation of one OSS community in which sustained participation is hypothesized to be associated with the coevolution of two major elements of LPP theory: "situated learning" (the process of acting knowledgeably and purposefully in the world) and "identity construction" (the process of being identified within the community).
SECI model of knowledge dimensions: Nonaka Takeuchi The SECI model of knowledge dimensions is a model of knowledge creation that explains how tacit and explicit knowledge are converted into organisational knowledge. The SECI model distinguishes four knowledge dimensions – socialization, externalization, combination, and internalization – which together form the acronym "SECI". The SECI model was originally developed by Ikujiro Nonaka in 1990 and later further refined by Hirotaka Takeuchi.
liminal approach – cf. the movement of individuals engaged in open source communities. open source communities and growing body of knowledge on corporate engagement in open source communities, our understanding of the movements of individuals within these communities is limited. To analyze these movements, we build on Arnold Van Gennep and Victor Turners’ theories on liminality. Through this lens, we build an understanding of the movements of individual members within open source communities.
