Map Creation
Map 1-
Once all the data was loaded onto arc-map, the base-map used was the grey canvas that was transparent by 50% so the labels that were set to black could show. The colors used for the two maps that are on that one page are contrasting to match the color wheel and the scale even though is set to the same units and magnitude. the coordinates used are consistent throughout and are set to WGS 1984 and all the other important elements were present. The map was symbolized to include two legends for each map on that page using graduated colors and the initial 9 decimal spaces was changed to zero decimal places because we are dealing with people and the only time decimal places would be necessary would be for date rates by percentage. More maps will be added but the as the data gets updated just showing the fatalities.
Map 2-
This is the map that will be used to analyze the rate at which the deaths spread from china to the rest of the world using flow accumulation. If the appropriate shape-file is unavailable temporarily shift to creating a map for the zip codes in Houston, and New York and chose specific dates prior to the the present day for the analysis step. (This step will take some time)
As time goes on add more maps and data while covid 19 related deaths continue or stop.
Note:If you use data from csse through arcgis online, make sure it matches the data that the cdc pushes out for accuracy. In the event that you do go through this route, make sure you use the extraction in the arctoolbox before you convert.
1. Scroll to extraction on arctoolbox
2. Click extract values to point.
3. Then follow the steps from there to extract you CSSE values to point.
4. Go to conversion tools and go to raster
5. Double click on point to raster and use your newly created point from CSSE to create the raster.
6. Make sure you go to raster analysis through "Environments" to make sure the "Mask" is set to the outline polygon where the interpolation will be displayed. This step is important to make sure that it actually shows on the geographic location being analyzed.
7. Click Ok and let it create the raster.
Once the raster is created, you use either the diffusion interpolation or the interpolation to analysis the concentration and the spread of the death at various locations.
The same steps can be followed if you start with the excel sheet. The only difference is you will have to convert the excel sheet to a table and a point using the latitudes and the longitudes. Once you have created
the point you can follow the previous steps to create the raster and then go from there to do the interpolation.
A point density could also be effective likewise in showing where the deaths are concentrated and symbolizing the death count to be displayed on top of the point density could be used likewise to create a better visual of where the deaths that occur are.
