● support for new requests: GetPropertyValue,
ListStoredQueries, DescribeStoredQueries
● does not include: CreateStoredQuery or
DropStoredQuery
● GML 3.2.1, paging and sorting
Intergeo 2014
Heat Map Layers
● kernel density estimation
● vector to raster transformation
● interpolation and render parameters
o
o
o
automatic scaling
interpolation in RGB/HSL color spaces
weighting per attribute/expression
● supports tile mode

Styleitem Javascript Plugin
● allows complex styles to be built
programmatically versus configuration
● integrates the Chrome V8 engine
● expose shape objects to javascript
● experimental feature for 7.0
● opens up many other possibilities including
feature processing and query templates

Text/Label Rendering Overhaul
●
●
●
●
●
removal replicated text layout support
work on list of glyphs instead of strings
integration of Harfbuzz library (optional)
supports complex layout (e.g. Arabic text)
Barely visible to the end user, but
– Exact label placement
(alignment/centering/letter spacing of text)
–
Intergeo 2014
Possibility of using one font per language

RIP - GD
●
●
●
●
casualty of the label refactoring
maintenance time sink
fewer use cases required it
consequences:
o
o
Intergeo 2014
lost support for bitmap fonts, but embedded TTF
lost write support for GIF (no outputformat)
Layer Level Encoding
●
Solves encoding handling problems e.g. data
sources in multiple encodings in a single mapfile
●
Data sources internally converted to UTF8
●
The mapfile has to be encoded in UTF8 now
●
All output generated by MapServer
in UTF8

Filter Translation
● currently MapServer handles filter processing
when it could be far more efficient to let the
driver do that work
● layer API function to convert MapServer
expressions to native “where” clauses
● huge performance improvements possible
Intergeo 2014
ScribeUI
● GUI mapfile editor
● Google SoC project (second year)
● key development achievements:
o
o
o
o
o
Intergeo 2014
replaced Flask framework with Pyramid
git integration
MapCache plugin
MVC architecture
improved stability
