I have latitude and longitude information like 26.847905 73.9575005 for about 800 points, I need to trim these lat/lon information to say 3 decimal places.
I used the following syntax in R
# Rounding off Coordinates of each of point to 3 decimal places shp1_DE$lon <- round(shp1_DE$coords.x1, 3) shp1_DE$lat <- round(shp1_DE$coords.x2, 3)
Now I have many points with lat/lon for example 26.847, 73.957 etc...
I want to summarize data to these points and form point-multipoint shapefile.
After that I need to create convex hull for each of these features. How to go about it in R?
