Someone had placed a POI in north western Tasmania for the Hampshire
district, but with k=place,v=country, so it was showing up as a
country label. I changed it to a hamlet for now.

Maybe so, but it's often the best way to tag things at present since
you can't have duplicate keys, but in this case you are grouping a
bunch of antenna to a tower...

There is 2 pieces of information, first the tower itself, and second
the transponder/transmitter information both have value.

That doesn't help any more than listing out the information in
individual sub-tags... In fact this makes things much worst since you
can't search individual aspects of each transponder/transmitter...
This information could be used to plan trips and roughly know where
each radio station covers based on the output and frequency, if you
then combine digitial elevation information you could have a pretty
good idea of ideal coverage...

Relations should only be used for "groups of objects in which each
object may take on a specific role".

I think the problem arises because it's ambiguous as to what you are
actually mapping. If mapping the *tower* (it seems you are, given
""), then I think *transponder*
information should not be shoehorned into the same element.

I'm not sure though...

Alternatively, if you think the *transponder* information really is a

communications_transponder:frequency=0.729;0.891. Or, you could
instead do something like

A few options for you there.

Fyi.

This is a worthwhile survey if you get the time.

GEOSS is a global framework that is being established with an aim to
share Earth Observation data (image and vector) via Open Spatial
Standards with Open Access to the data.

Subject: Request to Participate in GEOSS Survey [SEC=UNCLASSIFIED]


Ladies and gentlemen,

I am writing on behalf of Dr Sue Barrell, Australia’s representative
on the GEO Executive Committee, to invite you to participate in a
survey about Australia’s contribution to GEOSS.

About GEO

The Group on Earth Observations (GEO) is coordinating efforts to build
a Global Earth Observation System of Systems, or GEOSS
 . GEOSS commenced in
2005 with the objective of achieving comprehensive, coordinated and
sustained observations of the Earth system, in order to improve
monitoring of the state of the Earth, increase understanding of Earth
processes, and enhance prediction of the behaviour of the Earth
system. Now halfway through its 10-year implementation, we’re
interested in finding out the extent to which Australia has embraced
GEOSS.

About the survey

The survey has been designed to help gain a better picture of
Australia’s involvement in GEOSS, and therefore better represent
Australia’s interests in the GEO Executive Committee.

We wish to obtain a broad spectrum of responses from a variety of
sectors and accordingly gained your email address from a deep trawl of
possibly relevant lists of contacts and websites; we are hopeful that
this survey is relevant to your work interests. Our survey can handle
multiple responses from the one organisation, so please feel free to
on-forward as you see fit, however, it is requested that it is only
sent to Australian representatives or agencies.

The survey can be found at http://www.surveymonkey.com/s/8Y65W8G
 and should take no more than 5
mins to complete.

It is requested that the survey is completed by Thursday 27th May 2010.

Many thanks for you contribution,

Yours sincerely,

The ACMA data has inconsistencies, it lists the same site ID, but
gives different lat/lons for several locations. I'm still after
suggestions on how to tag multiple transponders for the same node, I
don't think tagging multiple nodes on the same spot is a good idea,
using a single node + multiple relations might work I suppose, but
that doesn't seem optimal either.

The ABC tower in Gore Hill has 17 transponders registered.

Most retention basins still have exits. During light rain water flows
out the exit. When rainfall is really heavy, the exit doesn't cope, and
the water backs up and fills the retention basin. It later drains away,
either into the soil or through the exit channel/pipe/drain. The exits
are deliberately made small to hold the water back and prevent flooding
downstream. (Source - a friend who used to work for the Water Board)

The current tagging scheme for doing transponders don't seem to take
multiple transponders on the same tower:




































The lat/lon is approximations only, since the ACMA still uses AGD66
instead of WGS84 or DGA94, and there is no simple formula to shift
locations, but should be closeish.
