[postgis-users] Commercial/Large datasets MapServer/PostGISsamplesites

[Chapman, Martin]

Eduardo,

We manage very large datasets (tens of terabytes) of raster and vector
data as well.  Our clients are the DOD, USGS, USDA, Army Corp of
Engineers, Navy, etc... .  We use open source exclusively for our
subsystems, which includes products like PostgreSQL, PostGIS, OSSIM,
GDAL, Proj4, OpenMap, RedHat Linux, and more.  Our solutions are rock
solid and out-perform our "commercial" competitors in both speed and
quality of product.  I came from a Microsoft world and was amazed at the
high caliber software the open source community creates.  In my mind the
question isn't an example of open source that shows power and trust, but
rather what commercial products out there can show the power and trust
that open source has demonstrated to our company.

Eduardo,

A belated response ...

Our company uses postGIS for storing data about our imagery (about 18
terabytes of image data in some 879000 separate files, growing at a rate
of almost 2 terabytes a week currently), and for a fairly substantive
database of vector data (detailed US streets, detailed parcels for
various counties in the US, watersheds and stream and lake data for the
country, flood data, etc.). Both image and vector will grow
substantially as we add more data outside of the US.

Currently the Mapserver implementations are limited to a few of our
customers, but in the next few months we'll be using Mapserver to serve
up imagery with vector data to the general public (currently the
equivalent service is running over 250k hits a day). The new service
probably won't be quite that heavy at first. We are currently doing load
testing and related work.

All of this used to be Informix based; cost was the main reason for
migrating to Open Source.

Not sure if this is heavy enough use to reassure your customer or not.

Hi folks,

Here I am again trying to convince a traditional "$pay software" 
consumer to accept free software... :-)

I'm looking for commercial websites or larget data set website to use as

example for the power, and trust of MapServer and PostGIS features.

Can anybody suggest one?

Best.
