Python package for reprojecting, gridding, and writing geospatial data to formats supported by GDAL

Code Credits:

• Trond Kristiansen - plotting and CorTAD module
• J. Gomez-Dans ([email protected]) - gridding module
• more TBA

• writefile: Given data and geo-points, writefile will write to file formats supported by the GDAL python, as well as a method for writing to ESRI's ASCII grid format (.asc).

• gebco: Extracts bathymetric data from gebco 1 degree and 30 arc-second global grids. Supports sub-setting given geographic bounds.

• cortad: Extracts SST data from weekly averaged cortad data. Modified from code written by Trond Kristiansen.

• pathfinder: Extracts SST from daily averaged pathfinder data. Supports subsetting by geographic and time bounds.

• sightsurvey: Imports data from textfile into structured numpy array for use with other modules.

• makekml: methods for creating Google kml files from dataset

• interpolate: Includes different interpolation methods for interpolating geo-spatial data.

• griddata: Re-samples point/value data to new grid dimensions.

• globcolour: Extracts Chl-a data from daily averaged globcolour merged chlorophyll data. Supports subsetting by geographic and time bounds.

• create method to create grid for sample area
• Re-sample to defined grid
• determine why gaps in geotiff files
• write method to write to ASCII grid
• Determine if effort is correct/ perhaps split by cruise leg
• print log/summary file with images
• check that chl-a method is working correctly
• check what is going on with bathy mirror problem, spot check depths?
• make sure land masses are masked
