matlab_scripts_ecomapper

This repo contains scripts I wrote for processing .log files coming from our EcoMapper AUV (which is basically an Iver2). These have last been tested and adapted for Matlab R2018a pre-release.

plotting all data from several missions, x: time, y: depth, color: sensor

To map/plot all data from all EcoMapper missions, use map_all.m / plot_all.m which will collect data from all missions in the specified folder, and plot 2D and 3D figures (plot_all) or a top-down view (map_all). E.g. to plot all sensor data from one day at the Puddingstone reservoir:

plot_all('~/data_em/puddingstone_20180419');
map_all('~/data_em/puddingstone_20180419');

plotting a single sensor from several missions, x: time, y: depth, color: sensor

To map/plot one type of data from all EcoMapper missions, use map_data_from_ecomapper_by_type / plot_em_by_type E.g. to plot only Chlorophyll data from one day at Puddingstone:

plot_em_by_type('chl','~/data_em/puddingstone_20180419')

plotting all data for a single mission, x: time, y: depth, color: sensor

To map/plot one type of data for one day of EM missions, EITHER use map_data_from_ecomapper_by_type_and_date / plot_em_type_date or use map_data_from_ecomapper_by_type / plot_em_by_type / map_all / plot_all and change the data_prefix_path to the specific log file. (Haven't tested this in a while.. :) )

creating interpolated data plots, x: longitude, y: latitude, color: depth

To create an interpolated data plot, run map_interpolated_data_from_ecomapper_by_type using any data type, for example water_depth:

map_interpolated_data_from_ecomapper_by_type('water_depth','~/data_em/puddingstone_20180419')

To create an interpolated bathymetry plot, you can also use the shortcut of running the map_bathymetry_from_ecomapper script.

non-interpolated top-down views

Examples:

map_data_from_ecomapper_by_type('chl','','~/data_em/puddingstone_20180419')
map_data_from_ecomapper_by_type_and_date('chl',19,4,2018,'','~/data_em');

notes

  • all the mapping scripts will use the mapping toolbox, if available, to plot on top of a map (last tested for Matlab 2012)
  • The following scripts can also be used interactively - they will open a dialog window where you can select the folder that contains the log files to be plotted: plot_all*, map_all, plot_em_by_type*, curtainplot_sensors_subset*
