GIS IN R• Analyze spatial data without QGIS or ArcGIS

• Simplest data

• Provide Many GIS Packages

• Applied Spatial Data Analysis with R (Roger S. Bivand, Edzer Pebesma and V. Gómez-Rubio/ UseR! Series, Springer 2nd ed. 2013)

SHINY IN R> install.packages(shiny) > library(shiny) > runApp()

- Interactive - Reactive UI - Base on Twitter - Bootstrap - HTML, CSS, javascript & jQuery

GIS PACKAGES

> library(DBI) > library(RPostgreSQL) > library(sp) > library(spgwr) > library(rgdal) > library(rgeos) > library(gstat) > library(utils) > library(Matrix) > library(spdep) > library(pgirmess)
