3 Source Data Open Standards Educa5on

4 Open Source Geospa5al Founda5on The Open Source Geospa5al Founda5on (OSGeo), is a non- profit non- governmental organiza5on whose mission is to support and promote the collabora5ve development of open geospa5al technologies and data. 10/29/14 ITS488 4

5 OSGeo an organiza5on of developers and users dedicated to furthering the goal of open source developing and suppor5ng major libraries, client applica5ons, and server technologies 10/29/14 ITS488 5

6 OSGeo s Mission Support and promote the highest quality Open Source Geospa5al SoRware

7 OSGeo's Goals Provide resources for FOSS4G projects: Infrastructure Legal frame Financial support Promote free and open spa/al data Create and maintain a quality brand Create and promote free curriculua Promote and contribute to standards

8 OSGeo Activities On a global scale: Provide mature sorware solu5ons Support FOSS4G, an interna5onal open source conference for geospa5al applica5on (2013: UK, 2014: USA) Support local ac5vi5es and capaci5es Local open source conference for geospa5al applica5on (i.e. FOSS4G- SEA) Local chapters (India,...) Facilitate inter- project communica5on Build a solid market for businesses and users Interface with industry and business Support the educa/on of domain experts not «brand- specialists»...

11 To the Heart of the Mader 1. Licensees are free to use open source sorware for any purpose whatsoever. 2. Licensees are free to make copies of open source sorware and to distribute them without payment of royal5es to a licensor. 3. Licensees are free to create deriva5ve works of open source sorware and to distribute them without payment of royal5es to a licensor. 4. Licensees are free to access and use the source code of open source sorware. 5. Licensees are free to combine open source and other sorware. 10/29/14 ITS488 11

12 Intellectual Property 10/29/14 ITS488 12

13 The Clever Bit What if you were to Explicitly license your source code to anyone who wants it, in such a way that they have the right to do whatever they want with it Turns the no5on of copyright on it s head! copyler Thus: Open source sorware is not given away rather, it is controlled via a license agreement under copyright law 10/29/14 ITS488 13

14 Two types of licenses Academic or A=ribu/on Licenses goal: a commons of code for all to use for any purpose you can do anything with the code, up to and including incorpora5ng it into closed/proprietary programs code can escape the commons but, you must give credit the original authors example licenses: BSD, MIT, Apache Reciprocal Licenses goal: a commons of code for all to share and share- alike deriva5ves must be under the same license code and deriva5ves cannot escape the commons considered viral, as can infect other code you introduce example licenses: GPL 10/29/14 ITS488 14

15 License Shopping OSI The Open Source Ini/a/ve non- profit organiza5on owns the Open Source Defini5on (10 basic tenets) cer5fies licenses as open source currently ~50 licenses listed The open source community does not need any more licenses! Use an OSI one do not write your own! You shouldn t have to struggle through learning the legal nuances You won t have to hire a lawyer Allow the community to sedle on a base set of common license (moral: it s all about reuse and coopera5ve development ) hdp://opensource.org/ 10/29/14 ITS488 15

16 Tools and Libraries A few libraries that are the founda5on of many Open Source and commercial Geospa5al SoRware Packages GDAL (Raster) and OGR (Vector) Geospa5al Data Abstrac5on Library / OpenGIS Simple Features Reference Implementa5on Tools for reading, wri5ng and processing of raster and vector data sets - > formats Important base for many Desktop GIS systems e.g. ArcGIS OGR extends MapServer formatsoracle Spa5al, ESRI Geodatabase (MDB), TIGER, MapInfo PROJ4 is a library for cartographic projec/on rou/nes stand alone projec5on u5lity proj libraries for more than 2500 projec5ons (e.g. EPSG list) GeoTools is an open source Java GIS toolkit GeoTools is a library for cartographic projec5on rou5nes Similar usage as OGR and GDAL for Java based projects Udig and GeoServer are based on GeoTools 10/29/14 ITS488 16

17 OpenStreetMap Community Meets Cartography Andy Robinson

18 Why? Exis5ng Data not Free & Open Ar5ficially S5fles Innova5on Data as a Sta5c Snapshot Near Real- Time data use not possible Real- Time data Interac5ve data edi5ng by users the next step

19 Quote 1 If you don t make [lower- resolu5on mapping data] publicly available, there will be people with their cars and GPS devices, driving around with their laptops.. They will be cataloguing every lane, and enjoying it, driving 4 4s behind your farm at the dead of night. There will, if necessary, be a grass- roots remapping. Tim Berners- Lee

20 Quote 2 You could have a community capability where you took the GPS data of people driving around and started to see, oh, there s a new road that we don t have, a new route.. And so that data eventually should just come from the community with the right sorware infrastructure. Bill Gates

21 How? Provide an Open Plaworm OSM Users may freely input and extract data Raw sources for OSM Basemap GPS track logs. Movement Breadcrumbs Exis5ng Free Data Sources (eg TIGER/LINE) Historical Maps Out of Copyright mapping Users Create Basemap from Raw Sources Via Online and Offline Edi5ng SoRware

22 Building Blocks Minimal Data Set for Maximum Flexibility Nodes Segments Ways/Areas Tags Metadata as key/value pairs Full User History and Rollback ability

31 OSGEO Live DVD originally compiled by Cameron Shorter, and one of the coordinators of the OSGeo- Live Project. a bootable DVD, based on the Xubuntu linux distribu5on, pre- installed and pre- configured with close to 50 of the best GeoSpa5al Open Source applica5ons along with sample datasets. OSGeo- Live can also be run from a USB flash drive, installed into a Virtual Machine, or installed onto your hard drive.
