python - Plotting satellite swath data using pyresample -

-

i trying plot full swath orbit of ascat ocean wind vectors , wvc quality flags using pyresample module. link ascat netcdf files can found here: ftp://podaac-ftp.jpl.nasa.gov/alldata/ascat/preview/l2/metop_a/12km/ documentation have read on module, not describe on how can find information within file satisfy geometry area definition. example code here below on plotting swath of satellite data

from netcdf4 import dataset      import numpy np pyresample import image, geometry import pyresample pr

i extract lons, lats, & wvc_quality_flag netcdf file

area_id = 'ease_sh' name = 'antarctic ease grid' proj_id = 'ease_sh' proj4_args = 'proj=laea, lat_0=-90, lon_0=0, a=6371228.0, units=m' x_size = 425 y_size = 425 area_extent = (-5326849.0625,-5326849.0625,5326849.0625,5326849.0625) proj_dict = {'a': '6371228.0', 'units': 'm', 'lon_0': '0',           'proj': 'laea', 'lat_0': '-90'} area_def = geometry.areadefinition(area_id, name, proj_id, proj_dict, x_size,y_size, area_extent) swath_def = geometry.swathdefinition(lons=lon, lats=lat) result = pr.kd_tree.resample_nearest(swath_def, wvc_quality_flag, area_def, radius_of_influence=20000, fill_value=none) pr.plot.save_quicklook('/tmp/tb37v_pc.png', area_def, result, num_meridians=0, num_parallels=0, label='flags')  attributeerror: 'module' object has no attribute 'plot'

first, error pyresample module not have attribute plot when documentation says , "area_def" never defined anywhere in ascat netcdf file. pyresample not plausible these type of files or not looking in proper place definitions within metadata of ascat file? clarification on module help! again!

there 2 questions here. first one, plot submodule.

plot submodule, , can imported here other submodules:

from pyresample import image, geometry, plot

second, target area definition defined on fly in block:

area_id = 'ease_sh' name = 'antarctic ease grid' proj_id = 'ease_sh' proj4_args = 'proj=laea, lat_0=-90, lon_0=0, a=6371228.0, units=m' x_size = 425 y_size = 425 area_extent = (-5326849.0625,-5326849.0625,5326849.0625,5326849.0625) proj_dict = {'a': '6371228.0',              'units': 'm',              'lon_0': '0',              'proj': 'laea',              'lat_0': '-90'}  area_def = geometry.areadefinition(area_id,                                    name,                                    proj_id,                                    proj_dict,                                    x_size,                                    y_size,                                    area_extent)

the source swath definition defined as:

swath_def = geometry.swathdefinition(lons=lon, lats=lat)

and assume lon , lat arrays have been acquired prior resampling.

ps. yes, pyresample meant these kind of tasks. don't need meta data files swath data, longitudes , latitudes array sufficient.

i try , create radar chart using chart.js has various colours each scaleline, or coloured between scalelines. wondering if possible? from: to: i have working graph, though there doesn't seem method change individual scale lines. kind regards leigh you can extend radar chart type this, so chart.types.radar.extend({ name: "radaralt", initialize: function (data) { chart.types.radar.prototype.initialize.apply(this, arguments); var originalscaledraw = this.scale.draw; var ctx = this.chart.ctx; this.scale.draw = function () { var linewidth = this.linewidth; // bypasses line drawing in originalscaledraw this.linewidth = linewidth; originalscaledraw.apply(this, arguments); ctx.linewidth = this.linewidth; var scale = this; // draw chart.helpers.each(scale.ylabels, function (label, index) { // color of ...

apache - Error with PHP mail(): Multiple or malformed newlines found in additional_header -

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
