21
System Selection General Considerations
  • Evaluate your goals within the census and adopt
    technologies accordingly
  • Evaluate the interoperability of software to best
    suit both current and future needs
  • Collaborate with different agencies and staff on
    the preferred software platform

22
Specific Issues to be considered in system
selection
  • Cost
  • Upgrades
  • LAN configuration
  • Training needs/Workforce
  • Ease of installation
  • Maintenance
  • Documentation and manuals
  • Help-line and vendor support

23
FOSS Applications Technologies
  • Geographic Database/ Analysis
  • Desktop Mapping
  • Web mapping
  • GPS
  • Conclusion

24
Free Open Source (FOSS)
  • Applications of which you can access the source
    code
  • Similar functionality as commercial software
    applications
  • Becoming less IT oriented and more GUI friendly
  • Provides useful information to users about the
    construction of applications
  • Provide the ability to learn how to construct
    tailored applications for specific uses
  • Allows for a more informed decision on what is
    needed outside the free and open source
    environment

25
Geodatabase
  • PostGIS
  • (postgis.refractions.net)
  • Allows the storage and management of
    geographical vector data directly from within the
    database (thus using standard SQL and its Open
    Geospatial Consortium extensions distance, area,
    buffer, overlay etc much like ESRI's SDE or
    Oracle's Spatial extension)

26
PostGIS
27
Geodatabase
  • Vector-based model
  • Importing and exporting ESRI shapefile data is
    straightforward.
  • Raster geodatabase are not available.
  • Users in Australia, British Columbia, Colorado,
    Portugal, Virginia, Georgia, Switzerland,
    Florida, Chile, Switzerland, Brazil, Sweden,
    Italy, Norway, New Zealand, Germany, Sri Lanka
  • WFP and FAO

28
Desktop Mapping Software
  • In the last few years, thanks also to a larger
    user base, the situation has vastly improved
  • QuantumGIS (http//qgis.org)
  • most advanced raster vector image and data
    display and manipulation
  • Thuban (http//thuban.intevation.org)
  • Vector-based strong limitations in the handling
    of rasters

GRASS
  • Short for Geographic Resources Analysis Support
    System
  • Historically known as a raster GIS, difficult to
    use, mainly command-line oriented.
  • Since 2002 it has known a heavy development the
    2D and 3D vector section, as well as the database
    integration, have been completely rewritten, and
    it is now available as a new (6.0) stable
    version.
  • Very complete, with all functions required for a
    professional use, from management and analysis of
    geospatial data to image analysis, from chart and
    maps production to spatial modelling and full 3D
    visualization
  • Can Be Accompanied with R statistical package
    (http//www.r-project.org)

Map Server Applications
  • Definition (GSDI Association ) Web Map Server-A
    service that can produce maps drawn into a
    standard image format (PNG, GIF, JPEG, etc) based
    on a standard set of input parameters.
  • The first Mapserver (also called UMN Mapserver
    http//ms.gis.umn.edu) has been developed
    originally by the University of Minnesota. It is
    OGC compliant (WMS 1.1.0, WMS 1.0.0, WMC 1.0, WFS
    1.0.0, SLD 1.0, GML 2.0, Filter 1.0.0, WMS 1.1.1)
  • Examples include pmapper (http//pmapper.sourcefor
    ge.net), Chameleon (http//chameleon.maptools.org)
    and Cartoweb (http//www.cartoweb.org)
  • With these tools, customized map server
    applications can be built in a very
    cost-effective way

    with GPS hardware

  • - gpsbabel http//gpsbabel.sourceforge.net)
  • - gpsdrive http//www.gpsdrive.cc).

Concluding Remarks
  • Several products are mature and ready for
    professional use, whereas others, while usable,
    need further development to be really competitive
    (setting aside the cost of acquisition)
  • UMN Mapserver is fully functional it does not
    have significant limitations, and in several
    respects it is superior to its commercial
    counterparts
  • PostGIS as a relational geodatabase is a very
    reliable and powerful solution, and has already
    replaced commercial top-end solutions

52
Cont.
  • For geographic analyses, GRASS is fully
    functional, stable and very powerful. In many
    situations (where money is an issue underfunded
    universities and public administrations, small or
    heavily competing companies, etc.) it is the best
    alternative to the (unfortunately very common)
    illegal use of (cracked or stolen) proprietary
    software. Its inherent qualities, however, allow
    its use also in large and more complex settings
  • Desktop mapping (and in particular QGIS) is
    usable, but still young some more months of
    development will be necessary to make it more
    stable and powerful

53
Open Source Contributions?
54
Cont.
  • What are the costs for Upgrades of hardware
    or/and existing software?
  • Is a LAN configuration needed?
  • What are the staff training needs/ Is the
    existing workforce adequate?
  • What is the ease and difficulty as far as
    installation of hardware/software as well as
    maintenance?
  • What infrastructure documentation, manuals,
    Help-line, and vendor support (patches etc.)?
