How to create a sonar radar using Gimp

Let's make sonar in a few easy steps using a free image editing software GIMP.

 
  Author: mat | Version: 2.6.11 | 10th October 2011 |  
 
 
1.
 

Open Gimp and create a new document. Fill it with black color.

In my case Foreground color is black.

 
 
2.
 

In the menu click Filters, Render, Clouds and choose Difference Clouds...

 
 
3.
 

Choose the same settings as I did and click OK.

 
 
4.
 

In the menu click Filters, Distorts and choose Waves...

Choose the same settings as I did and click OK.

 
 
5.
 

In the menu click Colors and choose Curves...

 
 
6.
 

Choose the Channel Green and make a same curve as I did.

 
 
7.
 

Select the Paintbrush Tool, choose the green color, choose the Circle Fuzzy (17) Brush and set the scale to 2.0.

 
 
8.
 

Click to paint some dots on your radar.

 
 
9.
 

Select the Text Tool, choose Terminal font in color green and enter the words next to the dots you painted.

 
 
10.
 

All we need to do now is to paint a radar line.

Select the Paintbrush tool, set the opacity to about 32 and scale to about 0.55.

 
 
11.
 

Click in the middle of the radar, press and hold the Shift key and drag your mouse to the end of your radar in any direction you want.

 
 
12.
 

Your radar is done and fully functional.

NREGA is crucial for reducing rural poverty. The Nrega Job Card helps workers access guaranteed jobs and wages. By viewing the NREGA Job Card List online, beneficiaries can confirm their registration, monitor wages, and keep track of their job history easily.

I found it really insightful how you covered that topic. Just one small thought: maybe adding a real-world example could help bring the point even more to life.
