Community
• The present:
–
–
–
–
June ‘03: ~800 users, June ‘04: ~1,200 users
19 developers, 15 documenters
core of very experienced users
new users are inexperienced in GIS, web
application development, or both
• The future:
– hopefully all those numbers go up
– there is a niche to be filled in training and
documentation
MapServer User Meeting 2004 - Ottawa, Canada
Cartography
• Recent work:
–
–
–
–
new style objects
support for GD anti-aliased line drawing
cartographic lines
graticule objects
• Future work:
– labeling enhancements: polygon label point
computation, MapText label engine support, label
prioritization
– symbol set re-write
MapServer User Meeting 2004 - Ottawa, Canada
Performance/Analysis
• Recent work:
–
–
–
–
non-8bit classification support for rasters
buffered polygon queries
connection pooling for SDE
spatial/temporal tiling extension
• Future work:
– integration of GEOS geometry engine
– reworking query interface to eliminate unnecessary passes
through datasources
– mapfile tokens, parse arbitrary chunks (or the whole file) as
strings
MapServer User Meeting 2004 - Ottawa, Canada
Data In…
• Recent work:
– Support for SDE versioned databases
– Simple MySQL feature support
– (indirect) GDAL/OGR drivers for OpenNDAP
• Future work:
– Oracle Spatial (the Brazilians are back!) support
brought to the same point as PostGIS and SDE
– real-time relational joins
– SDE joins (similar to PostGIS support)
MapServer User Meeting 2004 - Ottawa, Canada
…Information Out
• Recent work:
–
–
–
–
24-bit image output
PDF and SWF output
[shpxy…] tag for query processing
join support for dbf, csv and MySQL
• Future work:
– map rotation (CVS)
– raster queries (CVS)
– [shpxy …] support for dynamic feature thinning
MapServer User Meeting 2004 - Ottawa, Canada
OGC Interoperability
• Recent work:
– WFS client/server
– OGC Filter support
– WMS SLD support
• Future work:
– WCS 1.0.0 server (CVS)
– WMS/WCS compliance (darn square pixels)
– integration work with complimentary packages like
GeoServer for WFS/WFS-T support
MapServer User Meeting 2004 - Ottawa, Canada
MapScript
• Recent work:
– tons of “refactoring”
– unification of Swig and PHP-based APIs
– exposure of style and symbol objects
• Future work:
–
–
–
–
decent Java and .Net wrappers
exposing OWS interfaces
a thread-safe version of the C API
PHP5: to SWIG or not to SWIG
MapServer User Meeting 2004 - Ottawa, Canada
Client-side Development
• Recent work:
– MapClient, jBox/dBox, ROSA
– web mapping frameworks like DMS Chameleon,
ZMapServer and Moxi Media IMF (misclassified)
– mapserv CGI cookie support
• Future work:
– (pet project) Eclipse plugin for authoring
MapServer applications
– really slick UI’s from several small companies built
on top of the MapServer engine
MapServer User Meeting 2004 - Ottawa, Canada
Server-side Management
• Recent work:
– distributions: MS4W, Debian Linux and GISKnoppix
– application managers like MapDesk, MapLab and
AveIN!
• Future work:
– non-Windows installers
MapServer User Meeting 2004 - Ottawa, Canada
Challenges
• Prioritizing all that future work - money talks
• Project governance
• Competition from:
– other OpenSource GIS projects
– commercial outfits
• Keeping pace as technology advances
• Functional voids like routing and geocoding
