Using SBAS ArcGIS Pro

Installation & Launching SBAS

SBAS 2020 Toolbox after installation and expanded in the Catalog pane to show all the individual steps

SBAS for ArcGIS Pro is designed as an ArcToolbox written in Python, and installation is as simple as unzipping the distribution file to a local drive. The zip file includes the toolbar (SBAS_2020.pyt), layer packages (*.lyrx), a settings file (SBAS_settings.txt), and a template geodatabase (SBAS.gdb). The settings file is used by the SBAS tools to easily find the local SBAS database, and must stay in the same directory as the .pyt file. To launch SBAS create a new project in ArcGIS Pro and use 'Add a Folder Connection' to add 'SBAS_2020.pyt' to your project in the Catalog pane. Within the toolbox is the individual tools that you will use to create a sediment budget (Figure 1).

Creating a Sediment Budget

Set Local Database (Tool 00)

Tool 00 - Set Local Database is used to designate a known locality for your local SBAS database and provides the flexibility to have one or more local SBAS databases. Behind the scenes this tools is simply writing a string value into SBAS_settings.txt. Each time SBAS needs to locate the SBAS database in the data processing, it will put the value listed in this file.

Tool 00 preview.

Create SBAS Alternative (Tool 01a)

Sediment Budget data is grouped into Alternatives, which are representations of one set of assumed conditions for a sediment budget. Each alternative has its own set of littoral cells(with delta volume, placement/input volume, and removal/output volume) and fluxes. Alternatives may be created to reflect different assumptions about sediment-transport paths/rates and engineering activities, or they may reflect different time periods. Alternatives hold all values applied to littoral cells and fluxes, and the data is written to the 'Alternative table' in the local geodatabase.

• Tool 01a - Create SBAS Alternative is used to create a new alternative for a sediment budget (Figure). Basic information is collected to assist in building metadata for the alternative. The following pieces are data are required:

a. Budget Type (Micro or Macro)

b. Alternative Name

c. Alternative Description

d. Geographic Area Name or Description

e. Data From (Epoch)

f. Date To (Epoch)

g. Flux Q Units (Cubic Year/Year or Cubic Meters/Year)

h. Cell Volume Units (Cubic Yards or Cubic Meters)

Tool 01a: Creating the SBASAlternative

• Alternatives may be created to reflect different assumptions about sediment-transport paths/rates and engineering activities, or they may reflect different time periods.
• Alternatives hold all values applied to littoral cells and fluxes.
• Data is written to the Alternative table in the local geodatabase.

• There is a checkbox to Load New Alternative Immediately. If checkbox is ticked, 3 new layers will be added to the table of contents. Each layer will named "Fluxes for Alternative Name" or "Cells for Alternative Name"

Upon successful creation of a new alternative, the ArcPro Table of Contents will populate with three layers.

• As different alternatives are created, each are assigned a unique ID. This value is stored in the scenarioIDPK attribute field. When added to the Table of Contents, the SBAS tool pulls the supplied layer files (Cells.lyrx, AllCells.lyrx, and Flux.lyrx) and applies a definition query to the items that filters only on the assigned unique ID for the active alternative.

• Creating a New Alternative is the first step in building the geometry container to hold littoral cells and fluxes features. You will use additional tools - 02b, 03a, or 05a/05b to add geometry to the sediment budget alternative.

Load SBAS Alternative

• optional step
• Tool 01b - If an alternative was created using tool 01a, then Tool 01b - Load SBAS Alternative is used to simply load the respective feature layers (and definition query filters) into Table of Contents. Multiple alternative can be loaded at the same time.
• All available alternatives are listed in the drop down menu are that are stored in your local SBAS database.
• As different alternatives are created, each are assigned a unique ID. This value is stored in the scenarioIDPK attribute field. When added to the Table of Contents, the SBAS tool pulls the supplied layer files (Cells.lyrx, AllCells.lyrx, and Flux.lyrx) and applies a definition query to the items that filters only on the assigned unique ID for the active alternative.

Create SBAS Feature Geometry

LITTORAL CELLS

In SBAS there are 3 ways to create littoral cell geometry; sketching cells by hand, importing cells from GenCade outputs, and importing cells from existing GIS layers.

Sketching New Cells

drawing littoral cells by hand

1. Creating new feature geometry in SBAS, follows much of the same process inherent in GIS, however in SBAS we first have to start an 'SBAS Edit Session' so geometry is related to the correct alternative.

2. To begin launch tool 05a - Start Editing (Add Features)

3. A list of all alternative in the Table of Contents will be listed in the drop-down list. Choose the desired alternative and click Run.

4. In the background, SBAS sets the default values for the scenarioIDFK equal to that of the selected alternative. Remember, this is the value that is used in all of the definition queries.

5. Zoom to your area of interest and click on ArcGIS Pro's Edit ribbon and click on Create.

6. In the Create Features panel, click on the symbol in front of Cells for Alternative Name layer. This will expand to show you the sketch options. Click on the first icon. This is turn on your sketch tool. Click in the map to drop vertices for your littoral cell polygon. Double-click to complete sketch.

7. When done sketching all of the new littoral cell features, launch tool 05b - Stop Editing (Add Features) to commit your changes.

8. To Modify location of vertices, click on the Modify button from ArcGIS Pro's Edit ribbon. Click on Reshape, then Edit Vertices. Click on the vertices to move to new location or right click to remove. Save changes when complete.

Importing Cells from GenCade Data

When importing GenCade data, geometry for both Cells and Fluxes is created.

1. Littoral cells and fluxes defined in GenCade can also be imported into SBAS. Tools 02a - Plot GenCade Points and 02b - Convert GenCade Points to Budget Features are used for this data transformation.

2. For the data transformation, for the GenCade budget, the associated *.gen, *.slo, and *.map are required.

3. First run 02a - Plot GenCade Points. This will plot the shoreline point locations documented in the .slo file. The output shapefile is need for the input into 02b.

• What's happening behind the scenes:

The values are extracted from the .gen file

X0 and Y0 values = the starting coordinate

Azimuth

Dx = distance between points

The collection of distances from the starting location is collected for each date is extracted from the .slo file

A new point shapefile is created.

Note: if "Use only First Date in Point Plot" is selected in the tool, only the first row of the .slo is used to for plot.

4. Next open 02b - Convert GenCade Points to Budget Features. You will need to supply the 3 GenCade files, the newly created GenCade shoreline points, set temporary placeholder feature classes for the Cells and Fluxes, set design distant variables, and choose the Alternative that will be the home for these features.

Distance variables are for the design width of the littoral cells and the length of the flux lines.

• Distance (ft) Stretch Width of Littoral Cell - when this conversion tool is constructing the cells, the script builds a buffer around the shoreline position plot. The width of the buffer correlates to the width of the littoral cell. The value listed for this parameter is used as the buffer width.
• Distance (ft) Offset for Flux Arrows - when this conversion tool is constructing the fluxes, the script builds 2 flux arrows. The distance defined here defines how far apart the flux lines will be offset.

Coordinate system of the feature will be re-projected automatically to match that of the selected Alternative.

• The origin coordinate system is pulled from the GenCade *.map file between the COV_WKT PROJCS and END_COV_WKT tags.
• Sample Coordinate System Text:

COV_WKT PROJCS["NAD83_Delaware",GEOGCS["GCS_North_American_1983",DATUM["D_NORTH_AMERICAN_1983",SPHEROID["GRS_1980",6378137,298.257222101]],
PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Transverse_Mercator"],PARAMETER["scale_factor",0.999995],
PARAMETER["central_meridian",-75.41666666666667],PARAMETER["latitude_of_origin",38],PARAMETER["false_easting",200000],
PARAMETER["false_northing",0],UNIT["Meter",1]]END_COV_WKT

Cell and flux boundaries are pulled from the SBAS section of the .gen file.

• Cell boundaries are captured by the sequence of start/end definitions. In this example, there are 4 cells. Values represent point counter.

• V1 = start location of cell
• V2 = end location of cell

• Flux connections are captured by the sequence of start/end definitions. In this example, there are 5 fluxes. Values represent point counter.

• Q1 = start of flux
• Q2 = end of flux

Importing Cells from Existing GIS Layers

If you have GIS layers already created that represent cells or fluxes, but were created outside of this SBAS toolbox, these features can be imported into SBAS.

• If your existing features are to be a part of a new Alternative, use tool 01a - Create New Alternative to set up your Alternative Placeholder. Otherwise move to the next step.
• Using tool 03a - Import GIS Features to SBAS Alternative, browse to an existing feature class or shapefile, then provide field mapping to connect your original field names to the SBAS values.

• Field mapping for Littoral Cells include: Name, Description, Placement Volume, Removal Volume, and Volume Change
• Checking for Duplicate Geometries: This tool will check for duplicate geometries, or polygons and polylines footprints that already exist in the local SBAS database. If this is what you would like to do (e.g., you use the same cells for multiple alternatives), check the Duplicate Geometries OK checkbox.

FLUXES

Sketching Flux Lines

These are the instruction to create fluxes by hand - using either straight or curved geometry. Creating new feature geometry in SBAS, follows much of the same process inherent in GIS, however in SBAS we first have to start an 'SBAS Edit Session' so geometry is related to the correct alternative.

• To begin launch tool 05a - Start Editing (Add Features)

A list of all alternative in the Table of Contents will be listed in the drop-down. Choose the desired alternative and click Run.

In the background, SBAS sets the default values for the scenarioIDFK equal to that of the selected alternative. Remember, this is the value used in all of the definition queries.

• Zoom to your area of interest and click on ArcGIS Pro's Edit ribbon and click on Create.
• In the Create Features panel, click on the symbol in front of Fluxes for Alternative Name layer. This will expand to show you the sketch options. Click on the first icon. This is turn on your sketch tool. Click in the map to drop vertices for your littoral cell polygon. Double-click to complete sketch.
• When done sketching all of the new littoral cell features, launch tool 05b - Stop Editing (Add Features) to commit your changes.
• To Modify location of vertices, click on the Modify button from ArcGIS Pro's Edit ribbon. Click on Reshape, then Edit Vertices. Click on the vertices to move to new location or right click to remove. Save changes when complete.

Importing Fluxes from GenCade Data

Cells and Fluxes are imported at the same time with GenCade data import. Refer to this instructions in the Littoral Cells section above.

Importing Fluxes from Existing GIS Layers

• If your existing features are to be a part of a new Alternative, use tool 01a - Create New Alternative to set up your Alternative Placeholder.
• Using tool 03a - Import GIS Features to SBAS Alternative, browse to an existing feature class or shapefile, then provide field mapping to connect your original field names to the SBAS values.

• Field mapping for Littoral Cells include: Name, Description, and Q Value
• Duplicate Geometries: This tool will check for duplicate geometries, or polygons and polylines footprints that already exist in the local SBAS database. If this is what you would like to do (e.g., you use the same cells for multiple alternatives), check the Duplicate Geometries OK checkbox.

SBAS Feature Values

Manually Add SBAS Feature Values

Sediment budget values linked to cell volumes and fluxes can easily be added to geometry as feature attributes. Use these steps to add or modify values for Cells (Placement, Removal, Delta Volume, Confidence Level) & Flux (Q Values)

• From the Edit ribbon, click the Attributes button. This will open the Attribute pane.
• Select a budget feature (cell or flux) on the map with the Selection Tool. The Attribute pane will display the values for the selected feature.
• Click on the value next to the attribute to edit. Enter in the new value.

Attribute Values available to Edit:

Littoral Cells, user-defined values:

-sdsFeatureName (text, 50 characters). Name or label of the littoral cell.

-sdsFeatureDescription (text, 255 characters). Description of the littoral cell.

-removalVolume (double). Volume of sediment removal (per littoral cell and alternative).

-placementVolume (double). Volume of sediment placement (per littoral cell and alternative).

-deltaVolume (double). Change in volume per littoral cell and alternative.

-valConfidence (text, 255 characters). Determine level of data confidence, assigned by sediment budget author. Low, Medium, High

-projectID (text, 50 characters). Optional project id for internal management purpose.The SBAS application does not reference or write to this field.

Littoral Cells, dynamic fields:

For littoral cells, the residual, transportRemoval, and transportPlacement attribute values will automatically re-calculate each time the 06 - Recompute Residual tool is executed. Values for these fields DO NOT NEED to be manually updated.

-residualVolume: Computed Residual volume per littoral cell and alternative.

Residual is computed by Sum of Transport Placement - Sum of Transport Removal - delta volume + Placement volume - Removal volume.

SBAS tools will compute the residual volume based on values assigned to SBAS features.

SBAS determines the direction of sediment fluxes and automatically identifies each as either a "source" or "sink" for each cell.

-transportRemoval: Sum of transport removal per cell.

SBAS finds all sediment fluxes where the starting point of the line intersects the littoral cell. These fluxes are classified as "sink" volumes.

All sink volumes are summed and values reported to this field.

-transportPlacement: Sum of transport placement per cell.

SBAS finds all sediment fluxes where the end point of the line (arrow head) intersects the littoral cell. These fluxes are classified as "sources" volumes.

All source volumes are summed and values reported to this field.

Fluxes, user-defined values:

-sdsFeatureName (text, 50 characters). Name or label of the flux.

sdsFeatureDescription (text, 255 characters). Description of the flux.

-qValue (double). Volume of sediment moving in or out of cell.

-From the Edit ribbon, click the save button

Transfer Values into SBAS Cell Attributes

If sediment budget geometries and values exists outside of your local SBAS database in a feature class with identical geometry, the attributes can be transferred into your selected Alternative using tool 03b - Transfer Values to SBAS Cell Attributes. To use this tool to update feature values. The geometries in both datasets must match.

• Verify that the geometries in the SBAS dataset and outside dataset match.
• Open tool 03b - Transfer Values to SBAS Cell Attributes, select your desired input parameters and click Run.
• All values from your Input Feature Class will be used to update your littoral cell layer.
• A record of all transferred values will be listed in the Results Window.
• The residual is automatically recalculated.

Create Relationship to SBAS Features

Additional attribute data may be stored outside of the SBAS local database in feature classes . Contents from supplemental databases can be related to SBAS features using the 03c - Create Relationship to SBAS Features tool. This tool uses spatial and non-spatial relationships to determine how to connect the data attribute to the sediment budget. If you created geometry and values outside of this SBAS toolbox, but would like to use these in your budget, this tool will create a spatial relationship and add the correct SBAS foreign keys to easily join the datasets together.

• About Tool 03c - Create Relationship to SBAS Features tool

-Do you have data that uses the same geometry, does NOT have a SBAS key attribute, but has values you would like integrated in your budget? This tool should be used if there is not an ID field in the comparison layer and the geometry of the compares, and therefore a simple table join can not easily be performed.

-A FOREIGN KEY is a key used to link two tables together. A FOREIGN KEY is a field (or collection of fields) in one table that refers to the PRIMARY KEY in another table.

-The PRIMARY KEY for each littoral cell is littoralcellIDPK

-The PRIMARY KEY for each flux is sedimentTransportDirectionIDPK

-This tool adds a new FOREIGN KEY field to the comparison dataset: littoralCellIDFK or sedimentTransportDirectionIDFK

-This tool does NOT support Grouped layers. If this tool opens with a "No Parameters" message, or intended data layers are not listed in the drop down menus.

• Steps

• Open tool 03c - Create Relationship to SBAS Features tool.
• Select SBAS Layer : choose the layer in SBAS to which values will be related
• Choose Comparison Input Layer : select the layer outside of the SBAS database to be related
• Click run

Modifying Alternatives

Opening an Existing Alternative

Tool 01b Load Alternative Opening an Alternative is the function as Loading Alternatives. Use tool 01b Load Alternatives to complete this function. Loading an alternative will automatically load in the applicable data layers available to the Table of Contents.

• If an alternative was created using Tool 01a, Tool 01b - Load SBAS Alternative is used to simply load the respective feature layers (and definition query filters) into Table of Contents. Multiple alternative can be loaded at the same time.
• All available alternatives are listed in the drop down menu are that are stored in your local SBAS database.
• As different alternatives are created, each are assigned a unique ID. This value is stored in the scenarioIDPK attribute field. When added to the Table of Contents, the SBAS tool pulls the supplied layer files (Cells.lyrx, AllCells.lyrx, and Flux.lyrx) and applies a definition query to the items that filters only on the assigned unique ID for the active alternative.

Copying Alternatives

Tool 01c - Copy Alternative is used to copy and existing Alternative into a new Alternative. Use this tool if you would like to reuse the feature geometry for a selected Alternative. All features will be copied and labeled with the new Alternative ID (scenarioIDFK) value.

Changing Alternative Property Values

If you need to change any of the Alternative details like Name, Description, Start and End Date you can directly modify the Alternative table.

• In the Catalog pane, browse and expand the SBAS.gdb.
• Right-click on the Alternative table and select Add to Current Map.
• In the Table of Contents pane, right-click on the Alternative table and select Open.
• In the Attribute window, click the row/column value to modify.
• Enter any changes. When complete, from the Edit ribbon click the Save button. Note: If the Save button is disabled, hit the enter key (with the attribute table) to complete the change
• If you have renamed your Alternative, to see these changes reflected in toolbox right-click on the toolbox name and click Refresh.

Deleting Alternatives

Tool 07 - Delete Alternative If you need to delete an alternative, use this tool to remove the alternative from your personal database. This tool does NOT automatically remove any published datasets. If you have published a sediment budget to AGOL, and you would like to remove it, log-in to https://usace.maps.arcgis.com/home/index.html and delete the feature service from My Contents.
