scientimate.readxyzfile

x, y, z = scientimate.readxyzfile(xyzfilename, xyzfilelocation=None, zscale=1, domain='all', xmin=-180, xmax=180, ymin=-90, ymax=90, savedata='no', outfilename='xyzdata.csv', outfilelocation=None)

Description

Read and extract x (longitude), y (latitude) and z (elevation) data from ASCII gridded (tabular) xyz file
Use readdatafile function for more options

Inputs

xyzfilename
Name of xyz file between ‘ ‘ mark, example: ‘xyzfile.xyz’
xyz file should be in form of 3 coloumn format
xyzfilelocation=pwd
Location of xyz file between ‘ ‘ mark, example: ‘C:’
zscale=1
Scale z (elevation) data by factor of zscale
domain=’all’
Define a domain to be extracted from data
‘all’: all xyz data in input file are extracted
‘domain’: only data within a defined domain are extracted
xmin=-180
Minimum x (longitude) of domain to be extracted
xmax=180
Maximum x (longitude) of domain to be extracted
ymin=-90
Minimum y (latitude) of domain to be extracted
ymax=90
Maximum y (latitude) of domain to be extracted
savedata=’no’
Define if save xyz data in a file or not in outfilelocation folder
‘no’: does not save
‘yes’: save xyz data as csv file
outfilename=’xyzdata.csv’
Name of output file between ‘ ‘ mark, example: ‘xyzdata.csv’
outfilename should have ‘.csv’ extension
outfilelocation=pwd
Location of output file between ‘ ‘ mark, example: ‘C:’

Outputs

x
x (longitude) data extracted from xyz file
y
y (latitude) data extracted from xyz file
z
z (elevation) data extracted from xyz file

Examples

import scientimate as sm

xyzfilename='xyzfile.xyz' #e.g. xyzfilename='PersianGulf_ETOPO1.xyz'
xyzfilelocation='C:/' #e.g. xyzfilelocation='C:/datafolder'
x,y,z=sm.readxyzfile(xyzfilename,xyzfilelocation)

xyzfilename='xyzfile.xyz' #e.g. xyzfilename='PersianGulf_ETOPO1.xyz'
xyzfilelocation='C:/' #e.g. xyzfilelocation='C:/datafolder'
x,y,z=sm.readxyzfile(xyzfilename,xyzfilelocation,1,'all',-180,180,-90,90,'no')
