This is a top level workflow. This workflow includes all of the specific workflows needed in creating a general MODAEM project Newer and infrequent GMS users should start here.
To build a MODAEM model in GMS, use the following steps:
Expand1. Start GMS.
|
Expand1. Start GMS, or clear existing projects in GMS.
|
- If GMS is already running, select File | New.
- A new project can also be started by clicking New .
|
Expand2. If necessary, register or update GMS.
|
Expand1. Register GMS and components.
|
- Launch the GMS Registration Wizard.
- Follow the Registration Wizard instructions.
- Review the registered components in the Aquaveo License Registration dialog.
|
|
|
Expand2. Import data.
|
Expand1. Gather and open image files.
|
Images are imported into the GIS module in GMS.
Expand1. Open local images.
|
- Load images from local computer files using the File | Open... command.
- Alternatively, drag and drop the file into the Graphics Window in GMS.
|
|
Expand2. Gather and open geometric data files.
|
|
|
Expand3. Define the project boundaries.
|
Expand1. Create a new conceptual model.
|
- Create a new conceptual model with the "MODAEM" type.
Expand2. Add coverages.
|
Expand1. Create new coverage from scratch.
|
- Use the New Coverage right-click command.
- Use the Coverage Setup dialog to create a new coverage by selecting the desired coverage properties and naming the coverage.
|
Expand2. Create new coverage from an existing coverage.
|
- Use the Duplicate command on an existing coverage. This will copy any feature objects on the coverage.
- Use the Rename command to give the coverage a new name.
- Change the coverage setup.
|
|
|
Expand2. Create the boundary arc.
|
Expand1. Create feature points, arcs, nodes and vertices.
|
- In the map module, create feature objects in the active coverage.
- Use the Create Arc tool to create arcs in the map coverage.
- Begin creating a new arc by clicking in the graphics window at either arc end. If clicking on an existing feature node, vertex or arc, the new arc will snap to that object.
- Double-click or press the Enter key to terminate the arc.
- Use the Create Point tool to create additional nodes alone or to split arcs.
|
Expand2. Modify arcs.
|
- Feature arcs, whether digitized or incorporated from a boundary condition or a material coverage, often need to be edited after initial creation.
Expand1. Create additional vertices on arcs.
|
- Use the Create Vertex tool to add vertices along arcs.
|
Expand3. Split arcs.
|
- An existing arc can be split by:
Expand2. Add a node to the arc.
|
- Use the Create Point tool to add a node on an arc in order to split it into two arcs.
|
Expand3. Connect the end of an existing arc to the middle of the arc.
|
- Use the Select Points\Nodes tool to drag the node of an existing arc to anywhere in the middle of another arc. This will split the second arc into two arcs.
|
Expand4. Add a new connecting arc.
|
- Use the Create Arc tool to start or end a new arc on an existing arc to split the existing arc into two arcs.
|
|
|
|
|
Expand4. Create specified head arcs.
|
Expand1. Assign arcs as head arcs.
|
- Using the Select Arc tool, select head arcs.
- Select the Properties macro button.
- Assign head properties in the Attribute Table dialog.
