Info Pane: Component

The Component tab appears in the Info pane when the focus is on an opened window.   It displays information for the active layer or window such as the projection (coordinate system) for the component.   Clicking on a component shown in the Component tab will switch to that component in the Project pane.   

 

 

Move to Previous / Move to Next - Click to pick the previous record or the next record.  Will be enabled if an object or record has been picked with an Alt-click, and normally used mainly with the Values tab or the Coordinates tab.  This is useful for data sets where records are in order.  When records are not ordered in a table, as usually is the case in enterprise class databases, these buttons will be used mainly to step through relatively small selections, with the

Selected - Move only within selected records.  When enabled (only possible if there is a selection), constrains Previous and Next motion to the previous selected record or to the next selected record.

Go - Go to the current object or record in the opened window.

Coordinate System Picker - Manage the coordinate system.

Description - Open the Description dialog to enable entering or editing a description.  

Update Record

Press to apply any changes, such as changes in the Description.

 

 

 Illustrations in this topic may be reduced in size to allow more compact documentation display.   Undocked panes can be resized to be larger or smaller, but not as small as the smallest illustrations that may appear.

Maps

When a map has the focus the Component tab will report projection information for the map as well as for the active layer within that map.   In the illustration below the buildings layer is the active layer in the map.

 

 

 

The tab displays the active layer component, the table used by that component, the geometry field or tile field used, and the spatial index used. The number of records reported will report the number of rows in the source table (including those with NULLs for the geometry or tile field).   The Info pane will report the text field used for labels.   

 

Coordinate systems are reported in black color text if the coordinate system has already been correctly assigned, or in red color text if the initial coordinate system has not yet been assigned.  The records number reports the total number of records in the drawing (objects) or image (tiles).  

 

Tech tip: Clicking on any component shown in the Component display will highlight that component in the Project pane opening folders as necessary in the Project pane to show the component.

Drawings

When a drawing has the focus the Component tab will report projection information for the drawing as well as for the active layer within that drawing, if the drawing has more than one layer.

 

 

Coordinate systems are reported in black color text if the coordinate system has already been correctly assigned, or in red color text if the initial coordinate system has not yet been assigned.  

Tables

When a table has the focus the Component tab will report the number of records in the table.

 

 

Images

When an image has the focus the Component tab will report projection information for the image as well as for the active layer within that image, if the image has more than one layer.

 

 

 

Coordinate systems are reported in black color text if the coordinate system has already been correctly assigned, or in red color text if the initial coordinate system has not yet been assigned.  

 

Text Components

When the focus is on a text component such as a Comments, Location, Query, or Script component, the Info pane will report the number of lines of text.   For scripts, the Info pane will report the language used by the script.

 

Layouts

When a layout has the focus the Component tab will report the page size of the layout as well as the description.

 

Coordinate System in Black or Red

The Component tab in the Info pane is our primary interface for seeing and changing projections, that is, the coordinate systems assigned to components, and to edit those coordinate systems.  In Manifold, the terms projection and coordinate system are synonyms and are used interchangeably.   The Component tab tells us at a glance the coordinate system (projection) used by a component, and it also tells us at a glance if that coordinate system has not yet been correctly assigned.  

 

 

 

When a format or data source has specified the coordinate system to use, Manifold displays the coordinate system in black color.   If the coordinate system is shown in red color, that tells us the coordinate system has not been correctly assigned.  In that case, we must click the coordinate system picker button and choose Assign Initial Coordinate System to assign the coordinate system that should be used.

 

 

 

We use the Component tab for three key activities involving coordinate systems:

 

 

 

 

To assign, repair, or change a projection, click on the coordinate picker button.

 

Descriptions

The Component tab provides room for a text Description for the context component.   The description can contain whatever text we want, edited by clicking the [...] browse button.  Adding text using the browse button will cause the description text to appear.  

 

 

 If we start with a component that has no description, we can press the browse button to pop open an editing window.   We enter the description desired and then press OK.

 

 

The new description appears in the Info pane.    Descriptions in the Info pane will be word-wrapped to fit into the available width of the pane.

 

 

The text is in the Description property for the component, which we can create and edit manually in the Properties dialog for that component (right-click the component in the Project pane and choose Properties).  

 

 

Like all properties for components, the Description property appears in the mfd_meta table, seen above and selected for emphasis.    We can manipulate descriptions in the mfd_meta table by manually editing the table, or editing the table programmatically or using SQL.

 

 

When a component has a Description, hovering the mouse over that component will show the first line of the description as a tool tip.

 

Notes

Clicking on a component shown in the Component tab will highlight that component in the Project pane, opening folders as necessary in the Project pane to show the component.

Example: Edit Coordinates While Creating an Object - When creating an object in a map using a tool such as Create Area, right in the middle of the process we can edit coordinates in the Info pane Coordinates tab.   This example shows the step by step process.

 

Example: Edit Attributes and Move a Point - We look at the attributes for a point in a drawing layer and edit one of the attributes using a more expanded Edit dialog.  We then move the point to a new location. Easy!

 

Example: Edit Attributes, Larger Text, IME for Asian Languages - A tour showing how to edit attributes in a drawing using the Info pane Values tab and the expanded Edit dialog, including advanced Unicode facilities and use of the built in Input Method Editor (IME) to input text in Japanese language.

 

Example: Assign Initial Coordinate System - Use the Info pane to manually assign an initial coordinate system when importing from a format that does not specify the coordinate system.

 

Example: Change Projection of an Image - Use the Reproject Component command to change the projection of an image, raster data showing terrain elevations in a region of Florida, from Latitude / Longitude to Orthographic centered on Florida.

 

Example: Create Parcels from Traverse Files - Traverse files using ESRI traverse file format are widely used by surveyors and government organizations in the US to define parcels and lines by describing a sequence of directions, distances and curves from a starting point.  Manifold automatically handles both tangent and non-tangent curves in ESRI traverse file format as well as the full variety of options used to specify angles, distances and curves.  This video shows how it's easy to create a parcel from a traverse file.
