INterferometric SAR Data Analysis and Usage Software (INDUS)
|
INterferometric SAR Data Analysis and Usage Software (INDUS) is a SAC developed software for interferometric analysis of SAR datasets. INDUS is a self-sufficient, portable and containerized software developed in C++ and Python. All the required libraries are available in the container and can be run by any software capable to load the container. The software is capable of generating the deformation map as well as the relative elevation map. It also generates the coherence map that can be used for various change detection analysis. Currently, this software caters to interferometric analysis of ISRO EOS-04 SAR mission. Support to upcoming missions like EOS-09 and NISAR will be extended in the software for interferometric analysis.

AI based Solar power plants extraction for Indian states from Resourcesat LISS IV data
|
Solar power plants are extracted for ten Indian states (Haryana, Punjab, Gujarat, Madhya Pradesh, Rajasthan, Maharashtra, Karnataka, Telangana, Andhra Pradesh and Tamil Nadu). Combined installed capacity of solar power for these states is 81.87GW which is about is 90.2% of India's total solar capacity (90.76GW) . Automatic extraction of these Solar power plants are done using artificial intelligence based deep learning neural networks for the year (Jan-April) 2023. Indian Remote sensing (IRS) Resourcesat-2A LISS IV satellite data is used with 5m ground spatial resolution and three spectral bands green, red and NIR. The study also includes temporal change analysis of Solar Plants from 2018 till 2023. It is found that in the past five years solar power plants inventories have increased nearly 6.3 times in Rajasthan, 2.5 times in Gujarat, 1.5 times in Madhya Pradesh, 1.57 times in Maharashtra, 1.25 times in Karnataka, 0.3 times in Telangana, 1.87 times in Andhra Pradesh and 2.31 times in Tamil Nadu. This work is carried out under TDP- 202302021, titled “Deep learning Based Solar Plants Identification using high-resolution remote sensing data”.

NWIA - High resolution Remote Sensing Assessment and Analysis
|
India is blessed with an enormous diversity of wetland ecosystems which play a critical role in regulating carbon and hydrological cycles, resilience in climate change and land degradation, water related disasters, nutrient cycling, local economy etc. The concern for conservation and management of wetlands is increasing all over the world including India, due to increasing population pressure and developmental activities. Space Applications Centre, ISRO has generated National wetlands geospatial dataset using multi-date and multi-seasonal Resourcesat-2/2A LISS-IV datasets of 5m spatial resolution (approx. 4000 scenes). A wetland classification system based on IUCN/RAMSAR definition and amenability on remotely sensed data was used to classify the wetlands. Total twenty types of wetlands were mapped. Nation-wide mapping of wetlands at 1:10000 scale provides current status of wetlands, its type, extent, area, perimeter, location, distribution etc. Total wetland area estimated is 16.89 Mha, which is around 5.12 % of the total geographic area of the country. A total of 3.58 Million wetlands in number with 2.49 Million wetlands (area >= 0.1 ha) as polygon features and another 1.09 Million wetlands (< 0.1 ha) as point features have been mapped. Wetlands statistics along with geospatial analysis is being brought out in the form of an atlas. This National wetlands work is done under SARITA (SAtellite based RIver basin hydrological Techniques and Application) programme with the support of state remote sensing centres and various academic institutions.

Space based observation of Indian wetlands
|
India is blessed with an enormous diversity of wetland ecosystems which play a critical role in regulating carbon and hydrological cycles, resilience in climate change and land degradation, water related disasters, nutrient cycling, local economy etc. The concern for conservation and management of wetlands is increasing all over the world including India, due to burgeoning population pressure and developmental activities. Therefore, Space Applications Centre has carried out National wetland inventory and assessment-2nd cycle under SARITA (SAtellite based RIver hydrological Techniques and Application) programme of SAC, funded by Department of Space. This National wetland geo-database is developed using multi-date Resourcesat-2/2A, LISS-III datasets and with the support of many partner Institutions. Nation-wide mapping of wetlands at 1:50000 scale provides current status of wetlands, its type, extent, size, location, distribution, as well as decadal changes. Wetlands inventory statistics along with geospatial analysis has been brought out in the form of an atlas titled “Space based observation of Indian wetlands”.
