You might want to cross reference your list with those capabilites.
do a search on Oracle Spatial vs Oracle Locator for more info.
a blurb I found here:
http://atlis.nl/en/sis/knowledge/oracle-spatial.html
Oracle Spatial vs. Oracle Locator
Oracle Locator is a standard component of the database. Locator has the same geographical data structure and index mechanisms as Oracle Spatial, but lacks some functionalities. Functions and procedures for coordinate transformation, spatial aggregations and tuning options that are part of Oracle Spatial are missing in Oracle Locator.
If Oracle database products are used, there are no additional costs
for Oracle Locator. Oracle Spatial has to be purchased as an addition
to Oracle’s “enterprise edition” database.

want to go nuts until I received some feedback about the usefulness of
that type of functionality. They are not difficult to add. Are there specific
operators you are interested in and would be willing to test? Let me know
if so and we can work in the 4.9 branch.
A full list of operators supported by GEOS is available at geos.refractions.net.
As for mapfile integration. My idea was to expose a few operators that work of a single shape (e.g. buffer, convex hull, etc...) via the PROCESSING
block that is currently used for defining raster operations. That way you
could basically apply a GEOS operator to all features of a particular layer as
they are read from the data source- for any data source.

Hello all,listuser HH <[EMAIL PROTECTED]> 01/19/06 5:49 AM >>>
I would like to know how much of the GEOS functions (and which) are already available in the MapScript API and in PHP MapScript. I found only intersects and cointains for both. The shapeObj in PHP Mapscript also has buffer and convexhull.
Can someone tell me what the plans for including more of the GEOS functions are?
Are there plans to use some functions (i.e. buffer) directly in the mapfile?
Are there any docs that give some more information?

sorry for the late reply I was not in office.
At the moment I'm collecting arguments to convince costumers to use MapServer. I know there are many good reasons to use MapServer - mostly because of the good work you and the other developers did and do - but I want to give a full overview. I tested PostGIS a bit and I think that there is much potential but some of our costumers have Oracle and they will not use Postgres. So it will be nice to have some of the functions available in MapServer.
In the following I have made a list with the things I was thinking of. I give a ranking for the importance (1 - most / 5 - fewest).
- crosses -> 1
- (boolean) intersect -> 2
- (geom) intersect -> 2
- union -> 2
- difference -> 3
- getCentroid -> 3
- getLength -> 4
- getArea -> 4
- touches -> 4
- isValid -> 5
- disjoint -> 5
If others are interested perhaps we can open a poll for "Geometry functions in MapServer" with all the GEOS functions to see what would be important for a bigger group of people.
Thanks and my best regards
Norbert
