STDM Online Architecture and Services for Land Administration

862 views

Published on

Most people-to-land relationships worldwide are not recognized, identified or documented. Existing land administration systems are incomplete and do not perform. Lack of know-how, short lived projects and proprietary systems lock-in users and governments. Alternatives are needed. The Social Tenure Domain Model Software (STDM) is based on open standards and Open Source Software to avoid these common pitfalls.

STDM Online Architecture and Services for Land Administration

  1. 1. Land and Poverty Conference 2016 Scaling up Responsible Land Governance 14-18 March, 2016 | Washington, DC Arnulf Christl: metaspatial Danilo Antonio: UN Habitat John Gitau: UN Habitat Architecture and Services for Land Administration
  2. 2. GLTN BRIEFING AND PROGRAMME 2 / 14 CONTENT  The characteristics of Data  The characteristics of Software  The Need for Interoperability and Standards  STDM (The Social Tenure Domain Model) – Architecture – Standards – Software  Positive Impact of Open Source  Conclusions
  3. 3. GLTN BRIEFING AND PROGRAMME 3 / 14 The Characteristics of Data Geospatial data is: ● Big ● Complex ● Expensive ● Long-lived and persistent
  4. 4. GLTN BRIEFING AND PROGRAMME 4 / 14 The Characteristics of Software Software is: ● Small ● Simple ● Flexible and Interoperable ● Short-lived and ever changing... ● Free of Licensing Costs (Open Source)
  5. 5. GLTN BRIEFING AND PROGRAMME 5 / 14 Example I. Satellite Imagery: 2.2 MB MapServer™ software can serve 7 Petabyte of NASA imagery data 0 000 000 002 MB software 7 000 000 000 MB data
  6. 6. GLTN BRIEFING AND PROGRAMME 6 / 14 When is Software Complex? When it comes together. For geospatial projects we typically need: ● Operating System ● Database ● Data Creation and Capture Tools ● ETL Tools ● Analysis Tools ● Services... (and many more)
  7. 7. GLTN BRIEFING AND PROGRAMME 7 / 14 Example II. Ordnance Survey GB ● Postgres & PostGIS ● QGIS ● GDAL OGR ● GeoServer ● OpenLayers ● etc. Quality Open Source
  8. 8. GLTN BRIEFING AND PROGRAMME 8 / 14 Need for Interoperability and Standards Ordnance Survey Great Britain: ● ISO/IEC SQL (data management) ● OGC SFS (data store) ● OGC WMS (map service) ● OGC WFS (feature service) ● ISO 19115-1:2014 (Metadata) ● W3C TCP/IP (Internet Protocol) ● W3C HTTP (Hypertext Transfer Protocol) ● etc.
  9. 9. GLTN BRIEFING AND PROGRAMME 9 / 14 Bringing it All Together Data < Standards > Software ● First look at your data needs ● Then look at the processes you wish to perform ● Then check out which standards you will need ● Then start to test out different software with your data! ● Then design an architecture based on the standards ● Then add software into the architecture Make sure that any piece of software can be exchanged at any point in time!
  10. 10. GLTN BRIEFING AND PROGRAMME 10 / 14 STDM Online Requirements Use state of the art technology, minimize web traffic, support older hardware and any platform.  Record Household Information  Mapping components  Report Generation  Anonymyized Open Data Server
  11. 11. GLTN BRIEFING AND PROGRAMME 11 / 14 Snapshot of the current STDM Online Architecture
  12. 12. GLTN BRIEFING AND PROGRAMME 12 / 14 STDM Software and Standards The system is based on Open Source Software components including (besides others):  Postgres / PostGIS  QGIS MapServer  OpenLayers  GDAL OGR Open Standards help to keep the infrastructure open, including (besides others)  OGC SFS (Data format)  ISO LADM (Data Content)  OGC WMS (map content  OGC GeoPackage (transport)
  13. 13. GLTN BRIEFING AND PROGRAMME 13 / 14 Conclusions The Open Source development model has proven to be the right choice for STDM. Standards help to build a sustainable and open system which is:  Easy to Use  Powerful Functionality  Extendable and Customizable  Transparent and Secure The data model is open and standardized and is accessible by any other software package.
