How we plan to target the pollution issue plaguing Bali is by examining satellite images of Southern Bali. We will use aerial photos and satellite images to observe river basins, water sheds, polluted beaches and monitor population growth. There are several satellites we will use to gather data for our research.
SRTM:
The SRTM satellite is a satellite that composed a high-resolution elevation topography of earth. We will use these elevation images to examine large rivers, assuming the water ways are major transporters of waste from the higher elevation tourist cities such as Ubud and densely populated cities such as Bali's capital, Denpasar. SRTM images will be useful for identifying the major rivers and tracing their courses. The river basins should prove to be areas of pollution.
DMSP:
The DMSP satellite is a satellite that uses nightlight imagery, in which the lights are indicative of the densely populated areas that will be able to show us where there is high use of electricity that produces pollution. Areas around water including rivers and coastal communities are most susceptible to elevated levels of pollution.
Landsat:
The Landsat satellite allows you to see all the bands, in which we will only be using the bands 3,4, and 5. With the ENVI program we will use the inferred image to classify land regions and see the area's vegetation, water, and barren land and helping us identify where pollution is likely to occur and/or accumulate.
