Goal and objectives of the project
- Generation of the methodology for mapping saline soils from remote sensing images and field survey data
- Establishing the saline soil distribution maps from multi-temporal remote sensing images to serve the management of saline soils in Dong Nai province.
Main results
- Theoretical results:
o Building a model to extract saline soil index from multi-spectral satellite image data, this is an application that is not yet popular in Vietnam
o Establish the saline soil map in the study area, and the accompanying database, including: The saline soil map through periods, satellite images, field measurement data, and spectral reflectance of the saline soil
o Upgrade and develop more tools RESPEED to apply remote sensing and GIS to support socio-economic development in Dong Nai province
o Publish articles in scientific journals and local journals
- Applied results:
o Training and transferring technology to the locality with the RESPEED software tool, initially the receiving unit is the Department of Science and Technology of Dong Nai province. Expected to be implemented after the project is accepted at the Academy level: Department of Natural Resources and Environment, Department of Agriculture and Rural Development
The database and methodology for the establishment of the saline soil map will be handed over and applied in the gểnation of the land database in Dong Nai
Novelty and actuality and scientific meaningfulness of the results
- Researching, building a model to extract saline soil index from satellite image data, especially VNREDSat-1 image data, is one of the few studies on saline soil using remote sensing images in Vietnam
- Based on the needs and actual conditions in the locality, the project has upgraded and developed more functions for the software tools that have been transferred to the locality since the previous project. Thereby providing more information from remote sensing image data to support planning and socio-economic development in the DongNai province.
Products of the project
- Scientific papers in referred journals (list):
o Study on soil salinity by using Sentinel-2 imagery data: a case study in Dong Nai, Journal of Science on Natural Resources and Environment, pp59-67, No. 40, 2022
o Monitoring saline soil changes using remote sensing technology: Potential directions for land management in Dong Nai, Science and Technology Informations journals, pp 46-50, No. 3, 2022
- Technological products (describe in details: technical characteristics, place):
o The database on saline soil includes: the saline soil map over the period 2016, 2108, 2021; satellite image data, image map Sentinel-2; field measurement data; spectral reflectance characteristics of the sampling point (shown by spectral reflectance curve)
o RESPEED tool to extract saline soil index from satellite image data.
o Methodology for establishing the saline soil map from remote sensing images and survey data.
All these products will be stored at the Department of Science and Technology of Dong Nai province as well as the Vietnam Academy of Science and Technology.
Research region

Department of Science and Technology, Department of Natural Resources and Environment, Department of Agriculture and Rural Development of Dong Nai province.

Recommendations

The built model and RESPEED tool, which is simple, easy to use and completely free, developed by the project team in addition to being transferred to Dong Nai Department of Science and Technology. These results needs to be disseminated, transfer, exploit, use for socio-economic development in other agencies and departments in the locality, especially in the fields related to management, territorial planning, natural resources and environment.
