Review GIS page

[aspina7]

• need to update basemap section to align with case studies (ggplot friendlier packages + offline saving)
• link to / incorporate material from rspatialdata

[aspina7]

also need to review case density (heatmap) plots - the issue being we want to have cases/km^2^ and have not been able to accurately do this yet. A potential solution might be available in this code: https://www.r-bloggers.com/2019/05/kernel-spatial-smoothing-transforming-points-pattern-to-continuous-coverage/

or here: https://doodles.mountainmath.ca/blog/2019/03/27/density-timelines/ https://github.com/mountainMath/doodles/blob/master/content/posts/2019-03-27-density-timelines.Rmarkdown

two good options for basemaps: https://github.com/Chrisjb/basemapR https://jakob.schwalb-willmann.de/basemaps/index.html

for case density plots: https://github.com/wilkelab/isoband https://github.com/riatelab/tanaka also read: https://rspatial.org/raster/rosu/Chapter5.html

also cross linking with discussion on r4epis. https://github.com/R4EPI/sitrep/issues/20

Add in examples from {sf} friendly geostats package https://sfdep.josiahparry.com/index.html

close old issue

@jarvisc1 we should probably talk harmonising of packages across handbook, sitrep and gis course for tiles and point density
