Adding a new lake is very easy.
(1) Point a place to where a new lake will be added.
Point a place on the map to where a new lake will be added. Lake can be created on a depression or where the altitude is continuously flat. If you try to add a lake on a slope it will cause an overflow.
(2) Select [New Lake] in the pull-down menu of the right mouse button.
After putting the mouse pointer onto where water will be dropped select
[New Lake] in the pull-down menu of the right mouse button.
Then the lake property window will come up where you can setup items.
After filling up these properties the lake will be filled with water.
The property items are follows.
| Name |
| The name of the lake |
| Altitude |
| Define the flood altitude. Until this altitude the water will be filled up. |
| Natural |
| For natural depression this type should be selected.
If the depression is not perfect the water flows out from the notch. |
| Dam |
| For the place where it is not a perfect depression.
The water is spread out only to the same altitude. |
| Create Lake even if the water overflows. |
| This allowed for a natural lake to overflow.
Without this check additional lakes caused by the overflow will not be created. |
| Color |
| The color of the lake can be defined. This is only for the KashBird. |
| Transparency |
| The transparency of the lake can be defined. This is only for the KashBird. |
| Datum |
| Specify the datum for the coordinate given above.
Normally select WGS-48. Select TOKYO for Japan. |
| Datum Conversion |
| Use this function to convert datum without changing place of
the lake.
Consequently the coordinate value will change. |
| Copy |
| Copy the property into the clip board with comma separated format. |
Hint for generation a lake
IF filling of the water is is not successful try to setup a little higher
flood altitude or to change the selection of [Natural] and [Dam].
In case of a large lake set several points for the filling to support
a high resolution map.
There may be a case in which you do not have enough water.
There may be some difficulties with the digital maps which are caused
by non flat surface of the lake such as Lake Yamanaka.
