Mapping Canal as a `Water Feature'.

[nhk]

Greetings

1- Some Canals are being mapped as `Water feature'.

2- Unless I am wrong, I feel that since GMM has specifically provided
`Canal' as a Feature, the Canals should be simply mapped as Canal.
Canal is a `Line Feature' . A water feature can not be mapped as a
continuous line feature and it creates beaks.

thanks & regards

nhk.

In standard mapping, it has to be lined feature with Canal category
selected and with water polygon to cover the area it holds.

I think its just not canal but Distributary and other features should be used where appropriate.

Yes its for all water navigated features from rivers to smaller distributories.

Hi Guys

I wanted to ask about the Distributary Feature, I actually didn't get
a reason to use it. I saw it un-connected from both ends within
Sheikhupura, exactly besides a Canal. I didn't make any change to it
ofcourse I do not meant to. and I didn't get any help content about
this type.
- Could you please elaborate the both Distributary Feature along with
a Canal.?
- Should it be used only along with a Canal section? ofcourse I asked
it because I don't currently have an idea about that feature.
- Also I tried to find this feature in the Draw a line tool but there
is not any. I tried to find in other tools as well but didn't see it.
- I am also missing Channel or Canal type of feature in those tools,
what I have seen earlier but do not remember where, as I didn't this
feature yet.

Thanks
KA.

Right. These all categories are actually sub-categories of River and
the list drops down once a river is drawn. It's not very ideal as only
because of this reason many people don't know about these features and
they usually draw all water navigations as river.

Distributary is the water flow which takes water from it's provider
source to destination like fields. They normally emerge from canals or
even a distributary divides to make more. I've drawn many in triangle
area of GJR-Hafizabad-Wazirabad. You can see they normally finish in
fields.

PS based on these type of water navigations, Pakistan is one the
countries who has best irrigation system in the world. ;)

Pakistan has two type of water courses, canals and distributeries. canals get water and take them to water-courses and distributeries take water from one river to another river. if you know the canal name in Google you can find if its a canal or distributery.

Gents you might want to refer to this issue here BTW: Issue 276

http://code.google.com/p/google-mapmaker/issues/detail?id=276&q=momers&colspec=ID%20Type%20Status%20Priority%20Summary%20Stars

And this thread of discussion will be helpful as well

1- Canals are taken from Rivers. (Quite Sure)

2- Water Courses are drawn from Canals and go to the fields. (Quite
Sure)

3- Water from one River to another River is sent through `Link
Canals' - we see these names on Official documents.

4- Distributery, as I have read on many such structures are the
places from where a big Canal is divided into smaller Canals. I think
we need not get too involved in the WAPDA or Irrigation technical
terms. Big & small canals can be all called by their `Generic' common
name, understood by common Users, as `Canal'

Can somebody explain `Channel' plz. (I think Channel is a
Transportation term used where water navigation is done).

These are called channels actually. Example But some can be distributary as well. It all depends upon their size. Wider size is a channel and less wider is distributary.
