4. Abstract :
To visualize the heat values in terms of contour lines
in 3 Dimensional view and plotting the dynamic
isotherm lines over CDAT India map.
Contour is a line drawn on a map connecting points of
equal height. Contour lines connect a series of points of
equal elevation and are used to illustrate topography on
a map.
5. Abstract :
They show the height of ground above Mean Sea
Level (M.S.L.) in either feet or meters and can be drawn
at any desired interval.
An isotherm (meaning ’heat’) is a line that connects
points on a map that have the same temperature.
Therefore, all points through which an isotherm passes
have the same temperatures at the time indicated.
6. Abstract :
1. CDATClimate Data Analysis and Tool which is an
open source tool for plotting world map, contours and
isolines. Mainly it is used for meteorological department.
Finding the current temperature on overall India
cities from the google and using that temperature
values, plotting the isotherm lines on CDAT India map.
So that , we can view the current temperature values
on all cities in India in terms of isotherm lines.
7. Abstract :
2. Demonstrating how the contour lines are forming
by using Arduino board and heat sensors.
By setting the heat sensors in various temperature
and convert those heat values into contour lines,
interactively. We can view this contour in 3 dimensional
view using Matplotlib.
Matplotlib is an open source python library to plot and
view in 2 dimensional and 3 dimensional of the scientific
and mathametic terms.
16. What is Contour ?
Contour is line drawn on a map connecting points of equal
height .
Contour lines (also isolines) connect a series of points of
equal elevation and are used to illustrate topography on a
map.
They show the height of ground above Mean Sea Level
(M.S.L.) in either feet or meters and can be drawn at any
desired interval.

What is Isotherm ?
An isotherm ( meaning 'heat') is a line that connects
points on a map that have the same temperature.
Therefore, all points through which an isotherm
passes have the same temperatures at the time
indicated.
28. What is My Project ?
My Project is going to create the isotherm
lines, which will be plot on India Cdat Map.
We have 4 processes to do this . . .

What are the Uses of Isotherm ?
Isotherms are used to find regions with
* Warm air advection
* Cold air advection
* Short waves
* Temperature gradient boundaries and
* Instability zones.
