GIS more than just maps
Yes, we are all riding on the hype that Google Maps started, and the
endless possibilities it provides. But looking at it from a
planners/geographers perspective, are these possibilities really
endless?
In the Directions magazine, Adena Schutzenberger points out:

…
these services (Google Maps, Yahoo Maps, MSN Earth….) give programmers
all the tools they need to make maps. Indeed. It may be time again to
explore that age old question: what’s the difference between map making
and GIS? The former is about presentation (“a map is a representation
of structure, and a structure is a set of elements and the
relationships between them”). While paper maps are not interactive,
electronic maps may be, but that does not make them components of a
GIS. GIS, its proponents argue, is more than just mapping; it’s
analysis; it’s exploring what if; it’s using models; it’s developing
more intricate visualizations
Later on she points out,
that Googles proprietary Data and the inability to add data or dig into
it via web service standards, shrinks the ability for professionals
looking for more sophisticated webmapping functionality.
- …And,
what of standards? When Bret Taylor, Google Maps Product Manager, was
asked at Where 2.0 about plans to support OGC standards, he reportedly
said he was not familiar with the acronym. Is an open API and an
XML-based “storage format” or an RSS-based tagging procedure all it
takes to set aside the work of a formal standards setting body? Or,
perhaps we’ll have one set of standards (de facto?) for the consumer
set and another for the professionals?
Everybody
looking for Google Map like features (smooth panning and zooming,
annotations on maps…) without setting aside solid webmapping functions
(layers, queries…), should start looking into what the world of flash
or svg based maps, hooked up to MapServer applications has to offer.
