1.0.0 - Full Release of centerline-width Functionality

Feature in Alpha Release:

Convert raw data from Google Earth Pro to CSV

• extractPointsToTextFile()
• convertColumnsToCSV()

Find centerline and width of river

• plotCenterline()
• plotCenterlineWidth()
• riverWidthFromCenterline()
• centerlineVoronoi
• centerlineEqualDistance
• centerlineEvenlySpaced
• centerlineSmoothed
• centerlineLength
• rightBankLength
• leftBankLength

Export centerline to .CSV and .MAT files

• saveCenterlineCSV()
• saveCenterlineMAT()

Centerline	Centerline with Width Lines

Pytests: 180 test

plotCenterline() options, plotCenterlineWidth() width fix

New Features:

plotCenterline()

• centerline_type option to graph ("Voronoi", "Evenly Spaced", "Smoothed", "Equal Distance")
• marker_type option to graph (scatter/line)
• centerline_color option (matplotlib color options)

riverCenterline()

• ellipsoid option to convert degrees to meters

plotCenterlineWidth()

• Replace haversine package with geopy
• Remove unit options (will generate distances in km)
• Fix to prevent lines from being generated outside the polygon

Bug fixes and README.md edits
Pytests: 180 test

centerlineEqualDistance, saveCenterlineMAT, latitude_header/longitude_header

New Features:

centerlineEqualDistance

• New centerline type that represents equal distances from each points (set by user) and accounts for the radius of the Earth to convert from degrees to meters
• Set by equal_distance optional argument in riverCenterline (defaults to 10 meters)
• Can be saved in saveCenterlineMAT() and saveCenterlineCSV() as centerline_type="Equal Distance"

saveCenterlineMAT

• Save centerline values to a .mat file

latitude_header and longitude_header for saveCenterlineMAT and saveCenterlineCSV

• new options to set the header values for the latitude and longtiude in the output file by the user

Bug fixes and README.md edits

Pytests: 166 tests

Bug Fixes: Width Centerline

Bug fixes for returning the width based on centerline

User Warnings When Using Smoothed Centerline

User warning if smoothed coordinates need to use interpolate_n_centerpoints (useful for narrow rivers with sparse data)

• Example Error: WARNING: Partially invalid smoothed centerline due to sparse centerline data (6 points lie outside the polygon), fix recommendation: rerun riverCenterline to create river object with interpolate_n_centerpoints set to 62+

Include new centerline-width logo

Updated README.md example images and descriptions

Bug fixes

Access Specific Types of Centerline

New function calls to access centerline types

• centerlineVoronoi
• centerlineEvenlySpaced
• centerlineSmoothed
• saveCenterlineCSV()

Clean up cluttered graphs with fewer items

• Clean up plots on README.md

Bug fixes: Smoothed centerline accesses evenly spaced centerlines

Display Suggestions for Invalid Polygon

• check if invalid polygon due to flipped banks, display suggestions: Invalid Polygon Due to Flipped Banks, fix recommendation: rerun convertColumnsToCSV() and set flipBankDirection=True (or reset to default 'False' if currently set to flipBankDirection=True)
• Error handling when left_kml==right_kml
• Bug fixes, remove redundant code and spelling errors

Bug Fixes

• Update README.md to clarify function calls
• Additional pytests to account for user accidentally uses the same KML file for the left and right banks

River Class Object and interpolate_data argument

Rework functions to work through a riverCenterlineClass object with new argument to interpolate_data to fix jagged edges and gaps that can form in narrow rivers with sparse data

Convert raw data from Google Earth Pro to CSV

• extractPointsToTextFile()
• convertColumnsToCSV()

Find centerline and width of river

• plotCenterline()
• plotCenterlineWidth()
• riverWidthFromCenterline()
• centerlineLatitudeLongtiude
• centerlineLength
• rightBankLength
• leftBankLength

Beta Release: extract data and generate centerline/width

Beta Release for existing functions:
