I am very new to geographic data, so I am sorry for the stupidity of the question.
I need to plot some data that are in this projection
EUREF_FIN_TM35FIN
Projection: Transverse_Mercator
False_Easting: 500000,000000
False_Northing: 0,000000
Central_Meridian: 27,000000
Scale_Factor: 0,999600
Latitude_Of_Origin: 0,000000
Linear Unit: Meter
GCS_EUREF_FIN
Datum: D_ETRS_1989
in R in openstreetmap
.
I do not understand how the openproj works and looking at the guide here http://cran.r-project.org/web/packages/OpenStreetMap/OpenStreetMap.pdf did not help.
What I came up with is this
a<-min(min(samples$lon))#, min(samples_all$lon))
b<-min(min(samples$lat))#, min(samples_all$lat))
c<-max(max(samples$lon))#, max(samples_all$lon))
d<-max(max(samples$lat))#, max(samples_all$lat))
map = openmap(c(lat= d, lon= a),
c(lat= b, lon= c))
# ,minNumTiles=9,type=nm[i])
plot(map)
map_fin <- openproj(map.in, projection =
"+proj=utm +zone=35 +ellps=GRS80 +units=m +no_defs")
plot(map_fin)
that of course does not work, can you please help and maybe tell me where to find information about projection in R and openproj? I struggled a lot but could not find any.
Also how does this work with ggmap
?
