Comments on “GIS and Pandemic Planning” Having read this article, it became clear that GIS is very important in medical service and pandemic planning. Geographic information systems can provide doctors and scientists with the pandemic spread of disease by modeling geographical conditions in the given area and thus giving the idea of the impact of the disease on the group of people living in this area. GIS helps scientists simulate how an epidemic could evolve and model the potential impact of interventions such as social distancing. For example, one might create a routine in ESRI’s ModelBuilder™ to overlay maps of the distribution of affected populations (calculated using spatial statistics tools within ArcGIS or another program such as SAS or R), then intersect those polygons with other criteria such as infrastructure components impacting the health of the public (ESRI 14). The public healthcare community is likely to use GIS software and researches. Pandemic situations require fast reaction and rapid prioritization, and, of course, efficient distribution of medicine. As GIS software is compatible with many other software programs, it is quite easy for epidemiologists to defeat the disease within the limits of smaller areas. GIS provides them with geographical conditions of the area, allowing them to plan which types of medicine should be taken and how to reduce the spread of the virus including such outer factors as climate conditions, wind directions, if there are some mountains, or any other kind of upland surrounding the area, etc. also GIS provides scientists with “routing, travel directions, closest facility, and service area analyses” (ESRI 17). Also, one of the most important parts of any GIS is data. Without it, any research can be held. It includes road data, demographic data, etc. So, to plan at-risk populations the research should be based “based on the most recent epidemiological profiles and demographic data. They use GIS to identify geographic gaps in prevention, care, and treatment services” (ESRI 21). So GIS is a very useful direction to follow in pandemic response, as combining both geographical and social conditions, it is much easier to prevent the spread of any virus. Solving two geographical problems The statement of the first problem is to find the length of a 2 cm segment on a map of RF 1:50,000 on the ground. Based on the RF indication, where 1 cm includes 50,000 Km on the ground, we should multiply 50,000 on 2, and here we get that 2 cm on the map will be 100,000 Km on the ground. The statement of the second problem is to find the RF on the map where 5 cm equals 50 km on the ground. If 5 cm equals 50 Km, we should divide both parts by 5, and here we get that RF of this map is 1:10. Use of GIS in future work. Secondary sources of information in assembling a GIS database system. GIS technologies are very useful in many branches of work, specializations, and orientations. As was mentioned above, GIS is very useful in the healthcare field. GIS itself appeared because of medical issues. It doesn’t matter, which specialization or profession to choose, it is rather clear that GIS will be in use in any field. For doctors, it is useful
