Crop Identification and Area Estimation of Major Crops using Multi Temporal SAR data and Optical Imagery.
Used Time series Sentinel-1A SAR (VV, VH Polarization) data and Sentinel 2 data .
Study area was Veppanthattai taluk, Perambalur District, Tamil Nadu State, India.
Preprocessing of Images done using SNAP software.
ML Algorithms used for classification and compared their results - SVM, Neural Net, Max likelihood and Min Distance.
Identified the major crops and estimated their area.
Derived the temporal backscattering of all crops for VV, VH polarization.

Environmental Mapping of Kotturpuram, Chennai, Tamil Nadu, India.
My study area was kotturpuram road and CLRI. I have taken 15 point samples from this surrounding location.
Data Collected for five days from 26th September to 30th september using mobile phone applications.
Data collected such as noise, air temperature, surface temperature, relative humidity using survey technique.
The Interpolation is done for each data in the period of four days.
The output is mapped and it shows the variation of temperature, noise and humidity for each location.
Each Results are compared with other parameters .
Digital Soil Mapping of Rasipuram Block, Tamil Nadu, India.
Soil Profiles have been taken from legacy data.
Study area was salem and namakal block of Tamil nadu state, India.
SCORPAN model was used for prediction.
Predicted the soil properties such as sand, clay, silt and Organic Carbon using Quantile Regression Forest (Machine Learning ) algorithm in R Studio.
Prediction of performance evaluated based on the R2, RMSE, ME and PICP.
Results has average accuracy. In order to improve results has to add more number of training points and high resolution of DEM imagery.

Geospatial Web Application designed to monitor the major lakes of Coimbatore District using Sentinel-1 SAR data!
With just a few clicks, users can now explore the water area coverage of their selected lake on a specific date, gaining valuable insights into its dynamics and fluctuations.
But that's not all! This application also offers a comprehensive time-series analysis feature, allowing users to delve deeper into the historical data of their chosen lake over a specified date range. This functionality provides invaluable information for understanding long-term trends and patterns.

Development Projects
Web based e-Learning system
I developed e-Learning system for Tamil Nadu Agricultural University , Coimbatore, Tamil Nadu State-641 003, India.
Using of MOODLE open source ( LMS - Learning Management System ) software.
First I have installed a LAMP on Local ubuntu server. after that installed MOODLE and customized this LMS for TNAU to publish the demo courses on web.
Development of website using CMS
I developed website and suggested for Tamil Nadu Agricultural University, Coimbatore. Using of Drupal open source CMS ( Content Management System ) software.
Drupal is a free and open-source web content management system written in PHP and distributed under the GNU General Public License.
