NOAA Nautical Raster Maps and Grass GIS

After having some difficulty loading raster NOAA Nautical Charts into Grass Gis, I came across this page Converting NOAA raster charts to GeoTIFF for TileMill
I was not able to load the .KSP files for the NOAA rastermap (#12363- Long island Sound) into Grass GIS, with r.in.gldal despite its ability to handle .KSP files, but converting the files to GeoTIFFs first and then reprojecting worked perfectly. Determining the ESPG number was not readily apparent- as a workaround- I loaded the projection data (.prj) of an existing shapefile already existing in the Grass location into Prj2Epsg which returned a ESPG number of 4267.
1) Covert BSB to GeoTIFF
gdal_translate -of GTiff 12363.KAP 12363rectified.tif
2) Reproject GeoTIFF into final file (12363rectified-reprojected.tif) using gdalwarp and the EPSG number
gdalwarp -t_srs EPSG:4267 12363rectified.tif 12363rectified-reprojected.tif
3) Load final file via Grass GUI as you normally would.
The result is below- a NOAA rastermap overlain with vector bathymetric data (blue lines)
Everglades and Pythons

A bright point in the well publicized everglade python infestation is a new technique used to find the always difficult to find python- affix a tracking beacon to a male python, and let him lead you to a female. Go figure. Using this method- an 18 foot female python, with over 70 eggs was discovered. Go figure. If I recall correctly , in previous years there were well publicized hunts that failed to find many pythons- it seems the techniques and hauls have been refined and improved considerably, since the first Python hunt in 2013- with over 1,600 entrants and fewer than 70 pythons captured.
