Make the layer editable using either the layer Panel or clicking and selecting the Editing Pull Up in the status bar. These result in the points being created in a significantly different area:. Common errors include not specifying the correct projection, not multiplying or dividing the co-ordinates correctly. a boundary, OS background etc) to check the points have been created in the correct location. It is a good idea to open an existing layer (e.g. 
You will need to either create a new map window or add them to the current map window.
Press Ok, the points are created, but they are not immediately visible. Overwrite Existing Points: This is useful for correcting a previous attempt to create points that resulted in an error, otherwise leave this unticked. Co-ordinates that are in a different format may need to be multiplied by 10 (for 5 figure co-ordinates) or 0.1 (for 7 figure co-ordinates) etc. If the co-ordinates are in this format then leave this as 1. 
Multiply the co-ordinates by: MapInfo uses 6 figure co-ordinates for British National Grid. In the Create Points dialogue, select the column that contain the X and Y co-ordinates (Get co-ordinates from column). Use the menu to select Table, Create Points. It is important that the co-ordinate columns are either integer, decimal or float format. Use the menus to select Table, Maintenance, and Table Structure to check the column types. The file will now open in the Browser View. The CSV Information box, select whether the data is comma or tab delineated and whether to use the first line of the data for column headings. Ticking the “create copy in MapInfo for read/write” box allows the table to be edited otherwise it will be display only. In the File Open dialogue, use the Types of File pull down to select the file type (e.g.csv. Press the file open button or select File, Open. 
MapInfo can import most data interchange formats and then produce points from the co-ordinates. CSV files are commonly used for transferring data between databases in a simple text-based format. They can be organised into cells or columns by spreadsheet or database programs. A Comma Separated Value file contains data sets separated by commas, where each new line represents a new database row, and each database row has one or more fields separated by a comma.
Continue until you have traced the entire polygon/polyline and right-click to end.Ĭreating Points from co-ordinates ( x/y data)Ī common GIS task is to map a list of points with co-ordinates that may be supplied in a data format (e.g.xls. Polygon: Hold down the Shift key for the shorter trace path or the Ctrl key for the longer. Polyline: Hold down the Shift key or the Ctrl key and click. Move the mouse to another node of the same object:. Click on the first node of the polyline/polygon you want to trace. To trace the nodes of an existing polyline or polygon: Snap Mode must already be activated to use AutoTrace:. You need only specify the start and end point of the trace, rather than manually enter each node. AutoTrace ModeĪutoTrace automatically traces the nodes of a new polyline or polygon over existing features. This is useful when you want to draw perpendicular lines. This restricts new segments 45 degree increments relative to the last line segment. You can draw orthogonal (right angle) polygon line segments when you press the Ctrl key. Use the buttons to the left of the Drawing Toolbar to draw new features. Make the layer editable using either the layer Panel or by clicking and selecting the Editing Pull Up in the status bar. #MAPINFO 10 GEBERATE CIRCLE ON POINT HOW TO#
See the Style section on how to change the style for an entire layer. These change the style of selected objects. The buttons in the right section are to modify the style for:. The buttons in the left section are used to draw new features.
A utility company may wish to have to group all OS Mastermap together as a single grey background layer.įeatures are created and edited using the Drawing Toolbar:. A local authority should have separate data sets for kerb lines and street furniture which are typically points. However, the user needs to consider if it is good data management for a data set to contain mixed feature types. #MAPINFO 10 GEBERATE CIRCLE ON POINT SOFTWARE#
There is a notable difference between MapInfo and other GIS software as a MapInfo table (.tab file) can contain a mixture of object types. Vector data in MapInfo is comprised of points, lines and polygon features. In GIS software such as MapInfo, a layer can only contain the features from one dataset or table. The dataset may either contain raster images or vector data, but not both. Nick’s previous tutorial was on Thematic Mapping with MapInfo and Excel. This tutorial by Nick Williams, a MapInfo trainer at Acuity Training, provides an overview of how to create, edit, and convert features within MapInfo.
