On February 2006 Jo Walsh wrote (∗):
(∗
Google Maps / Earth and now MSN Live Local have been
big drivers for public awareness of digital mapping and
location technology. All of those services make some use
of publically funded, state-collected geodata (mostly in
state-
aerial imagery). Google Maps got so much interest
because it was so ''hackable'; developers with no
hackable';
cartographic knowledge at all could build their own
services on top of it, augmenting it from public-domain-
public-domain-
derived utilities like http://geocoder.us

Google and others affect (or “disrupt”) the
direction and future of the geospatial
community (∗)

“Recently, the product manager of Google Maps
was asked about supporting OGC APIs, he said he
was not aware of who or what OGC is”
(TC211, 2005)

… never heard about Telcontar ??
Yahoo, Google, Ask, … are powered by Telcontar
Drill Down Server platform … http://www.telcontar.com/
… implementing OGC Location Services (OLS) 1.0
… but not OGC WMS 1.x

4 main solutions exist to satisfy the “million or
more agog users” (TC211, 2005)

EC- 5 / 17

1) GoogleMaps API (Telcontar)
2) (alternatively) PushPinTM API … to have
something like GoogleMaps without Google’s
“disadvantages”
3) GoogleMaps API + “my own” WMS layers
4) CubeWerx OGC WMS Connector to integrate
WMS connector to Google Maps service

We were asked to implement something like
GoogleMap …
… without its “disadvantages”
… with “my” own data instead of TeleAtlas
… ISO-OGC compliant (eg. WMS)
ISO-
… for unskilled users
… publish and navigate
… customizable (new functionalities)
really FREE & REUSABLE

Conclusions
Google is not “disruptive” …
Main issues on Ajax and accessibility
OGC specs can be really and easily
implemented
SDI geoPortals ≠ COTS geoPortal toolkits
Local SDI experiences are better because they
are real:
