Re: GIS engine under Linux/Unix

Dear Hany, 
I'd like first to thank and congratulate you for this very powerful GIS
engine. I was also waiting for this detailed e-mail from your side that
could shed light for the community about your GIS engine.
I've searched about GIS and this adds some more clarification that I'd
like to share it here with the members.

GIS engine is simply a computer based tool that would be used in mapping
and data manipulation. The tool should address portability between a
wide range of platforms so it could be used in networking applications.
Hany had used the most portable open set of tools that could achieve an
excellent issue of portability. A very simple example of using GIS is
that : Imagine that we are about making a decision  of re-locating in a
new apartment: The decision is about multiple choices we do have in many
different Areas. The decision making will be built from using the GIS
engine ??? HOW ... 

The GIS engine is equipped with a data base for all these geographical
areas and their attributes : 
Other words : It has maps for Heliopolis, Nasrcity, Dokki, Mohandessin,
New Cairo , ......etc ... 
And the attributes could be : Electricity network , water network ,
waster network , clubs , streets , main squares, malls , groceries,
laundries, restaurants, universities, schools, people distributions,
urban compounds , ...... etc .. (THESE are each area attributes ).
Each one of  this attribute is mapped on the AREA geography map as a
LAYER. You can mis layers. for instance, I wanna my sons to be joining a
school. SO i'll recall from the database the ARea map and overlay the
LAYER of schools on it and at the same time i think of transportation
means so I'll recall on it the Bus stations around. Then I could make a
decision if this school is secure enough for the kids to come back early
or it is far away from transportation . All at a glance using the GIS
engine. ( Very simple example and so on .. ) You can choose the
apartment and its AREA upon collection information from the GIS that
could help you in making a decision which is WISE>!

Now , If u need more info and you are interested to know more
technically about this you could be visiting 
http://education.ollusa.edu/edtechnewsv1/whatisGIS.htm
or www.gis.com
I'm really interested to know more.... 

Hany, I'm into hardware as you might know .. So, I'll be so interesting 
in a project like OFOQ when it reaches some advanced stages at its road
map to run the GIS on its platform . Having a PDA that could run a Tiny
part of the GIS engine could be a fancy application. 

I'd to invite you to Host the Project under Handasa Arabia Organization
and start a mailing list after you get some interested developers and
I'm sure that you will have.. and I'm inviting all the members around to
share and participate the development of GeoINFO... 
Finally , Thank you so much for considering HA as a destination for
introducing your powerful GIS engine.

Note : All the information provided in the GIS examples is from a net
search that added to my knowledge about GIS applications. ( correct any
wrong piece if any )
