Dear All,
I have LISS IV satellite image. I need to do the coral reef mapping for the Lakshadweep lagoon area. Regarding this, Please suggest any algorithm or methodology do this.
I really appreciate any help you can provide.

1. Obtain high-resolution Landsat 8 or LISS-IV satellite images of the Lakshadweep lagoon area.
2. Use image processing software such as ERDAS Imagine or ENVI to pre-process the satellite images and create a classification map.
3. Use supervised classification and manually classify the satellite images into different land cover types such as coral reef, seagrass beds, mangrove forests, sand flats, and deep sea areas.
4. Use an accuracy assessment technique such as the Kappa Coefficient to evaluate the accuracy of the classification map.
5. Use a geographic information system (GIS) to create a map of the coral reefs in the Lakshadweep lagoon area.
6. Use a digital elevation model (DEM) to create a 3D map of the coral reefs in the Lakshadweep lagoon area.
7. Use GIS to analyze the coral reef mapping data and generate various reports.
Dear Sir,
Thank you so much for your Valuable reply. I look forward to more related research for my learning exercise.
With Best Regards

Since you have got the satellite image you can use scale conversion to reduce the scale of the map. firstly, compare original scale and new scale in order to reduce the size of the map that you likes on a paper. example 1cm is to represent 0.8km on the ground.
