Hi. There are lots of potential uses of this is WASH. You may be inspired by a small brief we made recently on innovation and technology applicable to WASH issues. GIS and RS are a major part of the brief. Link: https://www.wipo.int/publications/en/details.jsp?id=4497&plang=EN

Good luck. Peter Oksen, WIPO GREEN

GIS is a veritable method in decision-making. Now remote sensing can help you in processing and presenting locational data such as the pone you are interested in. However, you can merge all forms of data including Remotely sensed data using a GIS to arrive at your research question(s).

Remote sensing and GIS is a specialized application, spo you need to be computer literate as well as an experienced supervisor in the course of the research.

I am available if you need my assistance.

spatial analysis

Salah Hamad Thank you for your responds , but you mean i should do spatial analysis of the WHO's water and sanitation safety plans, please help elaborate

You can use spatial data (export excel data containing three axes, latitude, longitude and elevation) of water schemes constructed by partners for WASH programmes. GIS models use distance from the source as one indicator for your analysis.

I suggest before you engage in any kind of spatial analysis or DDS based GIS, You should write down your research problem and establish the criteria, and what kind of data you require

The spatial analysis may help you but you should be well aware of data building and importing.

Obtain the digital elevation model DEM, using remotely sensed data in Modis, Earth explorer, or ASTER DEM, using Gis application eg spatail analysis process the raster data and and upload your MASK from the DEM them use it to visual your terrain, pond lake river or watershed. Thank you

It's normal, one part of my tasks job... and that's for world good progress ..

Dear Ndamulelo,

Remote sensing capabilities and techniques are well suited for the monitoring of regional-scale precipitation, water budgets, soil moisture, and some measures of water quality. Other possible satellite imagery and remote sensing applications include catchment characterization, water quality monitoring, soil moisture assessment, water extent and level monitoring, irrigation service monitoring, urban and agricultural water demand modeling, evapotranspiration estimation, groundwater management, hydrological modeling, and flood mapping/forecasting. Various satellite data products have been leveraged to aid water and sanitation programs. Key examples include:

• The Sentinel-1 Program for water management in low-income countries was part of a large research initiative that explored the performance and opportunities provided by the European satellite Sentinel-1 for water resource management applications.

• In particular, LandSat 8 and MODIS data allow for a calculation of the Normalized Differential Vegetation Index (NDVI) and Evapotranspiration. Additionally, land use classification can identify the vegetation and population densities of rural versus urban, built environments. Have a look at these articles fro more insights:

• Using the Tropic Rainfall Measuring Mission (TRMM) data, the Nile Basin Initiative in partnership with NASA provides flood forecasts and water balance estimates for the Eastern Nile Basin.

• In Nigeria, the World Bank recently used geographic information system (GIS) mapping techniques to compare household survey data against MODIS land-use estimates to generate spatial distribution estimates of water and sanitation indicators, including service access

• In Dhaka, Bangladesh, the World Bank and other partners (the University of Massachusetts Boston, and Earth Observation for Sustainable Development/GiSat) used high-resolution imagery in slums to correlate satellite imagery to public service availability.

I hope it helps you.

Cheers

Ankur Srivastava thanks for your input but do you have a paper for this : In Nigeria, the World Bank recently used geographic information system (GIS) mapping techniques to compare household survey data against MODIS land-use estimates to generate spatial distribution estimates of water and sanitation indicators, including service access
