Visual information is more persuasive, and the map captures the extent of the damage based on differences in the landscape (Jiang 160).  The map was useful to generate and to make estimates of the total rainfall in the Eastern US to inform the weather forecasters and broadcasters, local administrators and the public. NASA was able to translate the satellite data into visualized and useful information  Data use in the mapTo visualize the dataset, layers were added and there was a satellite overlay added to provide visible satellite data as part of the tile data layer.  The layers are Weather and Vegetation, which are linked to the total rainfall, but the terrain is not shown  NASA generates the map images from the IMERG a satellite-derived precipitation dataset which depends on the data acquired, the NASA's Precipitation Processing System and satellites images in the GPM Constellation (Kirschbaum 1170). The data is acquired at specific points in time and merges data from various satellites. One of the challenges is getting the most updated information to various stakeholders. In representing spatial data, NASA utilizes the raster data models since the satellite images are used to depict the satellite rainfall and precipitation measurement. This is useful since the stored data varies continuously, which is necessary to estimate the rainfall. In any case raster data is utilized and the cells are regularly spaces, just as is the case with ph...
