This a comment from Anestis. I am doing this post on his behalf. Any help will be appreciated.

‘Ok, so here is the thing…I’ve created a table named ‘objects’:

obj_id number
name varchar(32)
shape MDSYS.SDO_GEOMETRY
timeslot number

In it I store points (MDSYS.SDO_POINT_TYPE) that change their coordinates randomly as time goes by. So for instance I now have stored 100 objects for 60 timeslots, that is 6000 records.

What I really wanna do is to visualise those points in a website moving. After a little research I started using Oracle MapViewer. I installed it and I used jview.jsp demo successfully.

What I wanna do has the following logic:

for (t=0;t

ok, tags issues…What I wanna do has the following logic:

for (t=0; t is less than max_number_of_timeslots; t++)
select shape from objects where timeslot=t;

Is there a way to do this?

thanx

I wanna do that in order to create motion. As if the objects are moving’

Hi,

My name is Georgios Xenakis and I am currently completing my Ph.D. with the University of Edinburgh. I am a forester and I hold a master degree in Resource Management by the University of Edinburgh. I got interested in Geographical Information Systems and Spatial analysis during my M.Sc. thesis. My first experience with G.I.S. was when I worked for the Forest Research Institute of Greece. There I saw for the first time the real application of G.I.S. in forest management. During my M.Sc. thesis I’ve try to introduce the “new” for me technology with more traditional forestry such as the predicting the sustainable yield based on yield tables. I’ve customised ArcView using Aveniue to introduce automated ways of predicting potential growth of Black Pine for Taygetos forest in Greece. With the application I was able to demonstrate the use of G.I.S. in forest management planning by providing maps of potential productivity and maps of the removable yield so as to ensure sustainability of resources.
