You need to get the CRS of the current project with g.proj, use the 'srid' key to get EPSG

I meant g.proj -g to get the srid key from the output which contains the EPSG:
g.proj -g
name=Lambert Conformal Conic
proj=lcc
datum=nad83
a=6378137.0
es=0.006694380022900787
lat_1=36.16666666666666
lat_2=34.33333333333334
lat_0=33.75
lon_0=-79
x_0=609601.22
y_0=0
no_defs=defined
srid=EPSG:3358
unit=Meter
units=Meters
meters=1

Hi there,
This is a basic implementation of my understanding of using
InteractiveMapwith custom projections.
