MI Table Editing
To edit a MapInfo table, firstly make sure the table is open in MapInfo set to Editable in Layer Control. For more information on this process please see Layer Control - editable.
The editing tool bars are shown below:
The upper toolbar contains the select, zoom, pan, information and a number of other icons. The green "i" symbol brings up the information cursor, this allows the user to click on an object to determine the data attributes of the layer. This useful for changing the attributes of the object.
In the second row of the image above the icons from left to right are:
- Point
- Line
- Polyline
- Arc (a
- Polygon
- Ellipse
- Rectangle
- Rounded Rectangle
- Text
- Frame (only available in Layout windows)
- Reshape
- Add vertex (node) to object
- Point Style
- Line Style
- Region Style
- Text Style
The arc, ellipse, rectangle and rounded rectangle should be avoided for TUFLOW modelling, use instead the point, line, polyline and polygon.
To create a new object in the editable table, select the symbol for the object that you wish to add and start drawing in the Map Window. For a point object each click will add a new point. For a line click and hold at the start of the line, move the cursor and release to terminate the line. For polylines and polygons, start the object by digitising the objects with a left-click, each additional click will add a vertex. To finish drawing the object double click or use the escape key.
TIP: If you draw a vertex in the wrong location you can use the backspace button to undo the vertices.
For help digitising a line or polygon along a common boundary see this page.
To change the style of an object you can set the style using the style symbols
