A python library that simplifies the access to the NOAA digital elevation map.

Requirements

If you want to use this library on any GNU/Linux or OSX system you just need to execute:

$ pip install noaadem

If you want to improve this library, you should download the github repository and execute:

$ make deploy

On Ubuntu Desktop there are some other libraries not installed by default (zlibc libbz2-dev) which may need to be installed to use these library. Use the next command to automate the installation of the additional C libraries:

$ make ubuntu deploy

Testing

To test all the project you should use the command:

$ make test

If you want to help us or report an issue join to us through the GitHub issue tracker.

Example

There are 3 methods to obtain the NOAA digital elevation map matrix:

  1. obtain
  2. obtain_to
  3. persist

The obtain method accepts 2 parameters the latitude and longitude numpy matrix:

from noaadem import instrument
from datetime import datetime

dem_matrix = instrument.obtain(lat, lon)

Next, the obtain_to method needs a standard NOAA CLASS netcdf filename to parse:

from noaadem import instrument
from datetime import datetime

dem_matrix = instrument.obtain_to('data/goes13.2014.124.123422.BAND_01.nc')

Last, the persist method needs a standard NOAA CLASS netcdf filename to save the variables:

from noaadem import instrument
from datetime import datetime
from netcdf import netcdf as nc

instrument.persist('data/goes13.2014.124.123422.BAND_01.nc')
with nc.loader('data/goes13.2014.124.123422.BAND_01.nc') as root:
    print nc.getvar(root, 'dem')[:]
