“…NESAC is responsible to carry out the operational projects for the North -Eastern region. Additionally, NESAC is mandated to provide application services like natural resource management, space and atmospheric sciences, satellite communication for teleeducation, disaster risk reduction, governance and development since its inception in 2000 (Raju et al, 2016). ISRO/DOS is promoting space technology services through training, education, research and capacity building at national / international level through its important institutions established across the country such as Indian Institute of Remote Sensing (IIRS, www.iirs.gov.in), National Remote Sensing Centre (NRSC, www.nrsc.gov.in), Indian Institute of Space Science and Technology (IIST, https://www.iist.ac.in/), and NESAC (www.nesac.gov.in) IIRS played important role in initiating and expanding geoinformatics training, education and research (Raju et al 2007) at India level and as well as at International level through Joint Education program in collaboration with ITC (Raju and Dadhwal 2010).…”

Abstract. India is one of the top space-faring nations in the world, which not only to build satellites and launches them using indigenously developed launch vehicles but also spearheads the use of space technology for many applications at the national and international level. Training, education and capacity building (TECB) are important components in promoting the use of space technology, thereby benefitting the society. North Eastern Space Applications Centre (NESAC) is one of many institutions under the umbrella of Indian Space Research Organisation (ISRO), Department of Space (DOS) which is responsible for promoting TECB at National level. ISRO / DOS also supports TECB at an International level through many initiatives such as IIRS – ITC JEP, UN-CSSTEAP, CEOS, UNSPIDER, UN-FAO, WMO, Commonwealth, and BIMSTEC etc. NESAC established in 2000, initiated capacity building and spearheaded Outreach programs from 2019 in the North East Region of India. Prime Minister of India announced in the plenary meeting of BIMSTEC(Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation) Summit at Kathmandu, Nepal in August 2018, recognizing NESAC to conduct space technology training programs of two weeks and 3 months for BIMSTEC Countries every year for the next five years with full financial support from Government of India. The first two week training program on “capacity building on the earth observation applications and research” was successfully conducted for 24 participants, four participants each representing Bangladesh, Bhutan, Thailand, Myanmar, Nepal, and Sri Lanka. The participants are from User Departments, Science and Technology Ministries, Space Organizations and Academia and Research Institutions. The training benefitted the participants from state of the art training facilities and experienced faculties from NESAC/ISRO/Academia from across India. The summary of feedback from the participants (excellent – 57%, good – 40%, average – 2.6% and poor – 0.4%) indicates that the course is very much useful as it has enhanced their knowledge in earth observation, geospatial analysis capabilities that will be put into use on their return. The training and capacity building has opened new vistas of cooperation and possible collaboration between BIMSTEC countries ranging from availing satellite data, expansion and access to data sharing portals, creating knowledge network to promote young researchers and expert sharing within the region, further to expand the capacity building by initiating distance learning programs, taking up joint research and application projects, etc. The rich experience of conducting a unique program, one of its kind and detailed feedback and possible expansion of BIMSTEC programs in the future is presented in the paper.

“…In recent years, with the development and application of remote sensing technology, it has played an increasingly important role in natural resource surveying [3,4], dynamic monitoring [5,6], and natural surface water planning [7,8], thus attracting researchers' attention. Remote sensing images enable us to observe the earth from a totally different perspective and monitor its real-time changes.…”

Abstract:The extraction of urban water bodies from high-resolution remote sensing images, which has been a hotspot in researches, has drawn a lot of attention both domestic and abroad. A challenging issue is to distinguish the shadow of high-rise buildings from water bodies. To tackle this issue, we propose the automatic urban water extraction method (AUWEM) to extract urban water bodies from high-resolution remote sensing images. First, in order to improve the extraction accuracy, we refine the NDWI algorithm. Instead of Band2 in NDWI, we select the first principal component after PCA transformation as well as Band1 for ZY-3 multi-spectral image data to construct two new indices, namely NNDWI1, which is sensitive to turbid water, and NNDWI2, which is sensitive to the water body whose spectral information is interfered by vegetation. We superimpose the image threshold segmentation results generated by applying NNDWI1 and NNDWI2, then detect and remove the shadows in the small areas of the segmentation results using object-oriented shadow detection technology, and finally obtain the results of the urban water extraction. By comparing the Maximum Likelihood Method (MaxLike) and NDWI, we find that the average Kappa coefficients of AUWEM, NDWI and MaxLike in the five experimental areas are about 93%, 86.2% and 88.6%, respectively. AUWEM exhibits lower omission error rates and commission error rates compared with the NDWI and MaxLike. The average total error rates of the three methods are about 11.9%, 18.2%, and 22.1%, respectively. AUWEM not only shows higher water edge detection accuracy, but it also is relatively stable with the change of threshold. Therefore, it can satisfy demands of extracting water bodies from ZY-3 images.
