thank you for explaining spacecraft, I wasn't clear about this (while for
communication it is clear that one-way communication is still
communication).

sure. I read this as agreement to use the basic term also for "small"
household dishes?

To an American engineer (I can speak with some authority, *being* an
American holder of an MSEE degree ;) ) 'communication' comprises
either transmission or reception, or both, and 'spacecraft' includes
'satellite'. In each case, a more general term was chosen over a
less-general one.
I don't mind mapping any sort of satellite_dish, but the attributes
would have to depend on what you're mapping them _for_. Using them as
landmarks ("turn right just past the building with six huge satellite
dishes on the roof") is surely different from using them as amenities
("this neighbourhood has a communal satellite dish over *here* where
you can see news"), and of course the attributes would differ.
I have mapped such things, but never tried to upload the data to OSM -
it was proprietary to the customer, and of considerably less interest
to the world at large.
[OSM-related information ends here. Feel free to stop reading]
(All this was twenty years ago, by the way.) I don't think I'm
breaking a confidence to say that significant attributes were the
capabilities of the station:
- transmit-capable, or receive-only (referring to data transmission
*through* the spacecraft, not command of the spacecraft)
- uplink power
- able to command the spacecraft
- able to BE commanded remotely through the satellite network. Most
stations were not always staffed but were commanded from a central
location. Some simply monitored a particular channel on a particular
spacecraft, and needed a visit from a technician to change the antenna
pointing, frequency or polarization. Some could be commanded
out-of-band by telephone modem, and most had modems available as a
backup command channel in case antenna pointing was lost; this
included a "phone home" function if a "heartbeat" command was missed
too many times in a row.
- pointing capability: single-spacecraft; multiple geostationary
spacecraft (longitude range(s) specified); inclined-orbit
geosynchronous spacecraft; Molniya-orbit spacecraft. (The network in
question used no other orbits. There are many, but most others would
have to be described in terms of altitude/azimuth ranges and slew
rates.)
- number of receive channels
There were also a lot of attributes relating to connection to
terrestrial networks (microwave and optical), operational status, and
of course a whole pile of related attributes - name, contact
information (both for the modem and for "get a human over there"),
several identifiers for addressing equipment on the network, a lot of
information relating to maintenance of the station (including
information such as who the service contractor was), ... it turned
into a Big Complicated Messy SQL Database, as so many operational
databases do.
The project, of course, was building the network operations center for
this particular network. We did have a big screen with a map of the
network and real-time status display of the operations, but that was
mostly to impress visitors. The operators found that an alphabetized
list of the station identifiers with "drill down" into detailed status
available with one click was considerably more useful; with about 400
fixed and half a dozen mobile ground stations, the displays just got
too busy otherwise.

"Here is where you get to watch the news about the rest of the world," "Here is where you watch the broadcast educational stuff," kind of thing. But that's probably better handled as some sort of amenity tag (here is where you can watch TV) rather than a physical mapping of dishes. That said, as you observed, there seem to be a lot of dishes in that image so I wouldn't map them as they're not for the public. I could see where it might be useful to somebody to map them to show the uptake of the technology in given areas, but that's what uMap is for. If that's why Enock wants to do it, I might be amenable to a new tag that doesn't get rendered which could be picked up on uMap automagically with an overpass-turbo query, but maybe the db guys would object to that level of clutter. -- Paul ___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging

I agree with you but in our case for the fact that this a slum. We thought this will serve a purpose. Yes many more useful things will be mapped soon :). Not 90cm across dishes into OSM this time.

Re: [Tagging] Specific tag for Satellite Dishes
I agree; I spent a few minutes trying to improve the page a bit. However, I don't see much benefit from mapping private household satellite antennas: the dishes in the linked picture above are only 90 cm across, and they are on just about every house. Maybe there are more useful things to map in Ghana before adding these minor features? On 7/29/19, Martin Koppenhoefer wrote: > Am Mo., 29.

Probably most satellite dishes are set up for communication with satellites, generally most of them being only receivers.

Re: [Tagging] Specific tag for Satellite Dishes
I looked into this myself, back when I noticed that some large dishes were mistagged as radio telescopes. For huge communications dishes, there is tower:construction=dish to be used with man_made=tower and we even have a satellite-dish style rendering for this at Openstreetmap-carto, for some reason. This should probably only be used for "tower"-sized dishes, not small household ones? For smaller satellite dishes, there is man_made=satellite_dish - documented at https://wiki.openstreetmap.org/wiki/Tag:man_made%3Dsatellite_dish - but note it is suggested that "This attribute is not suitable for private house antennas". I think this tag might be suitable for very large dishes too.
