Select Layers Screen
General
The following screen is used to identify the GIS layers to be used in the current project (these GIS layers should have already been added to the Map Document) and to access layer-specific screens (via the Go> buttons) which add specific data or selections to each layer. After completing and saving the data for each layer, the user is returned to this screen. The GIS layers accessed on this screen can be completed in any order. The Done button is used to exit this screen and return to the Main Menu.
After Go> is clicked, a dialog box is displayed for some layers for entering key field names in the associated attribute table. For example, the dialog box for Weed Layer requests the name of the column that stores the weed names.
Screen Items
- Load dBase from file: Use to select a database table that was previously developed for another project.
- Load dBase from Map: Use to select a database table that was previously added to the map document.
- Add>>: Click to add the selected items to the table displayed on lower half of the screen.
- Save: Click to save changes and to create the table displayed on lower half of the screen and added to the map document.
- Clear Table: Click to clear the table displayed on lower half of the screen. That button clears just the information in the table, to store any changes the Save button must be clicked as well.
Items (rows) in the table displayed on lower half of the screen cannot be edited. If a change is needed in a row, delete that row (right mouse click on row, in first column, to be deleted and select delete), make the appropriate selections in the fields on the screen, then use the Add button to create the corrected row. The option to sort a table by a selected column is accessed by a right mouse click on the title of that column. This can help the user check tables for completeness. Remember to save the changes before leaving the window.
