Map and Layer Control Solutions

Layer Grouping

I have a set of layers which appear in maps as a group. Ideally, they should be displayed and manipulated as a group in layer control.	Use layer groups in the LayMan map grid.
Alternatively, Right click on one or more table or table catalog nodes:	Defining a layer group Set up your map and load the LM map grid. 1.      Select the layers to be grouped 2.      Click on the first selected layer group cell and type the group name (allRds). Enter to complete. 3.      The name is applied to all selected layers. 4.      Repeat for other groups within the same map, assigning a different name. 5.      Note that grouped layers do not need to be from adjacent layers in a mapper. Just select the layers using ctrl-click if they are not adjacent.
	Whenever a map containing layers with a group definition is loaded, the groups are set and displayed in collapsed mode. Double click to expand to the component layers.
	Setting Attributes on Grouped Layers When you select a grouped layer, the corresponding navigation nodes select. If a layer attribute is set in collapsed mode, all component layers are updated to the master value regardless of their previous settings.

Dynamic layer control

I need to configure a map with multiple style and label changes, but see the changes as they are made, rather than resolving conflicts with multiple layer control sessions.	Use the LayMan map grid
	Set up your map and load the LM map grid.
	Confirm a layer for changing
Click the grid cell to change an attribute...	Confirm the change and continue..

Changing attributes for multiple layers simultaneously

I have style changes to make to multiple layers simultaneously and would like to apply the same change to multiple layers. I would like to tune font sizes quickly for these layers.	Use the LayMan map grid
	Select the layers to be changed.
	Click a cell and make the change
	Confirm the change and continue..

Extended layer information

For performance and accuracy, I want to check that all layers in my current map have the same projection and datums.	Use the LayMan map grid
	Double click the Info button to expand these columns
	No or mixed datum  indicates potential problems which should be resolved.

Table Catalog Solutions

Find tables that contribute to a map

I have a new project and need to review what maps I have available in the project area. I have 5000+ TAB files on my network including seamless, linked and WFS tables.	Use the LayMan Table Catalog
	Double click the catalog to load and display
	Open an index map or a map known to cover the area of interest.
	Zoom to the project area. Filter the catalog to show all tables intersecting the map window.
	If necessary, filter the list further by selecting table types and contents.
	Select a table and confirm its coverage.
	Continue opening tables from the list. They will be added to your map in optimal order.

Use an index of image tiles to identify tile names

I have a seamless table of image tiles, but would like to identify each by name. I cant select or use the Info tool in MapInfo Pro and have to resort to toggling visiblity on each layer.	Use the LayMan Table Catalog
	Double click the catalog to load and display
	Open an index map or a map known to cover the area of interest.
	Use the catalog filter to show intersecting, image and seamless tables. Select them all and click Show table bounds.

Workspace Solutions

My tables have moved!

My TAB files have been moved to new locations on the network and workspaces now fail on open. I cant use an editor to change all my workspaces as the path changes are not consistent. There are too many directory locations to use the MapInfo Pro search directories.	Use the LayMan Table Catalog and Workspace Safe mode.
	Empty the catalog if necessary and rebuild for the new table locations. (Start at the root drive directory to ensure all tables are found).
Build workspace catalog if not already done.	Select the workspaces to be corrected and click Run ..in safe mode. Each is opened in turn, run and corrected where possible.
Uniquely located table paths are substituted from the table catalog. Unlocatable and unused tables (not referred to elsewhere in the workspace) are commented out ...	Workspace correction.
Note: If there are 2 or more tables in the catalog with the same table name, an automatic (unprompted) substitution will not occur. No substitution using the approximate name match method will be used. Run a single selected workspace to enable prompted corrections (as shown in the next solution).	If you have duplicate names on your system, you might restrict the table build to your base tables paths until the workspaces are corrected.

Dealing with workspace errors

A workspace fails with an error due to an unknown table.	Use the LayMan Workspace Step Execute or Safe Mode to correct.
Step Execute and Safe Mode pause when an error is found. If the error is a missing table, a list of exact matches in different locations or approximate matches is presented.	Select the closest table from the approximate match list.

Workspace Independence

I have several workspaces that I need to run consecutively and combine the output maps on a layout. Any subsequent open workspace produces errors due to open table references to already open tables.	Use the LayMan Workspace Catalog and Workspace Safe mode
Table open references to already open tables are skipped.	Run the first workspace conventionally. Locate the 2nd and 3rd in the workspace catalog and Run Safe.
