SDB GUI 3.6.1

Release Note

• Remove Auto Negative Sign option and replace it with depth direction assignment on main window
• Add depth direction option on data save window

SDB GUI 3.5.1

Release Note

• Add train data selection based on attribute selection in addition to random selection (based on percentage)
• Add new field containing depth values of the output DEM to its corresponding points in test data file
• Add report containing RMSE, MAE, and R squared calculation using generated depth from train data and real depth value from test data (result accuracy) in addition to calculation using generated depth from test data and real depth value from test data (model performance)
• Saving scatter plot using executable file now works (surprisingly)

SDB GUI 3.4.1

This update comes with an ability to generate a scatter plot of the result.

However, the executable version could not generate the plot without getting the GUI terminated itself.
I found that the problem comes from generating executable file using auto-py-to-exe with matplotlib inside the source code.
Unfortunately, the problem has not been solved yet and if you want to generate a scatter plot of the result, please use the source code instead of the executable file.

SDB GUI 3.3.2

Bug fixes on possible error while importing raster data containing -inf or inf values inside its array

SDB GUI 3.3.1

New update features:

• Exclude points which are out of image boundary. This feature can be turned on (default) or off in Processing Options. It is recommended to turn this feature off when the depth sample points are inside the image boundary to save some time (seconds).
• Replace null values in the image with -999.0 value to avoid error when loading image with some null values. Remove null values from from features after point sampling so it does not included in model fitting and depth prediction. (See Workflow).
• Change SVM default kernel to rbf instead poly because it is faster.

Also, there are now two notebooks. One of which is explaining the workflow without excluding points, and the other one explaining the workflow by excluding out of bound points.

SDB GUI 3.2.1

New update featuring

• Export of training and testing data split in ESRI Shapefile or CSV format
• Choose whether to save DEM prediction result or not

SDB GUI 3.1.2

Minor update on file selection. While user selecting file, it will open the latest directory opened using SDB GUI

SDB GUI 3.1.1

Bug fixes on SVM option. The polynomial degree input didn't get into process in the former releases, but showing change on report because of user change it to other values even though the value didn't get processed.

SDB GUI 3.1.0

• New Processing Options button which control overall processing workflow instead of only selected method (except Random State). The options are Parallel Backend selection, Processing Core number (n jobs), Random State, and Auto Negative Sign CheckBox. Random State control the randomness of splitting train and test data. Auto Negative Sign Check Box will allow user to disable automatic minus-ing depth sample while most of the depth sample is positive. Please refer to joblib.parallel_backend to see details of Parallel Backend and Processing Core number (n jobs).
• Applying different and faster method of extracting raster values of a certain depth point sample based on its coordinate.
• Format filtering of sample data, so only point type of ESRI Shapefile is allowed.
• Bootstrap option enabled on random forest method

SDB GUI 3.0.0

• New workflow on depth sample handling which require user to load depth sample in ESRI Shapefile format instead of text file format
• Automatically reproject depth sample to match image CRS (Coordinate Reference System)
• Point sampling on image raster values and depth samples inside SDB GUI
