How to design a class and attributes to store multiple object coordinates?
Hello.
There is data that comes with the kml file.
Example:
<Temperature>
<56 78> <
103.777.0.8
104.8.0.567987 104.0.67878641 104.3, 0.677898 104.456.0.8 103.8.1.45678>
Accordingly
, there is a class with attributes:
class "
WEEATHER
" I realized that it is better to put the coordinates in a separate table to store multiple coordinates.
Class "GEO_COORDINATES"
..... Can
you please tell me what attributes (and attribute type) should be in order to store a bunch of coordinates?

Sorry, I don't understand the question.
The coordinates are two numbers.
If the coordinates are given in the form <degrees'minutes''seconds.fractions_seconds> , then it is easier to immediately convert them to the form <degrees.decimal_degrees> - and this is a banal number with a long (or fixed - this is not so important) point. Transformation is elementary.
We forget tightly about the northern and southern latitudes, as well as about the western and eastern longitudes. enter negative and positive, or simply move the range only to positive.
In any case, when we did a GIS project, we made this decision at the beginning and never regretted it later.
