[GIS] Offline Python or C++ library for plotting locations on map

cgeolocationplotterpython

I'd like to plot locations using longitude and latitude coordinates using Python or C++, is there a good library for such a task?

I know that matplotlib is an option, I'm wondering if there are any others?

Mapnik is a c++ toolkit for making maps and has python bindings – http://mapnik.org

Reproject your polygon into 4326

france_wgs84 <- spTransform(france_L93, CRS("+init=epsg:4326"))

Reproject your dataset into Lambert93

data <- structure(list(centerid = c("0121H1", "0121H2", "0218H3", "0303H1", 
"0303H2"), latitude = c(46.2236804, 46.2236804, 49.3700842, 46.3429172, 
46.3429172), longitude = c(5.2108193, 5.2108193, 3.335127, 2.6089958, 
2.6089958), adresse_complete = c("900 Route de Paris, 01440 Viriat, France", 
"900 Route de Paris, 01440 Viriat, France", "46 Avenue du Général de Gaulle, 02200 Soissons, France", 
"18 Avenue du 8 Mai 1945, 03100 Montluçon, France", "18 Avenue du 8 Mai 1945, 03100 Montluçon, France"
)), .Names = c("centerid", "latitude", "longitude", "adresse_complete"
), row.names = c(NA, 5L), class = "data.frame")


coordinates(data) <- ~longitude+latitude
proj4string(data) <- "+init=epsg:4326"
data_L93 <- spTransform(data, CRS("+proj=lcc +lat_1=44 +lat_2=49 +lat_0=46.5 +lon_0=3 +x_0=700000 +y_0=6600000 +ellps=GRS80 +units=m
+no_defs"))
