  1. Lab1: Layer Characteristics You have just been given a CD that contains MapInfo format data layers of parcels, streets, and target zones. Your supervisor asks you to take a look at the data and display the layers in various colors and label the features. How will you complete this task? In this lesson, you will learn how to: open data in MapInfo format; change the data characteristics (line width, color & fill) so that you may view multiple layers at the same time; label features in MapInfo; display data in different views. What are views of data in MapInfo? Map (display data features- points, lines, or polygons) Browser (attribute or data in fields) Graph (Pie, Bar, Line, 3-D, etc)

  2. Data Views: Graph Map Browser

  3. How to display a data layer & control display characteristics in MapInfo: To open data layer- SelectFile> Open 1 3 2 5 1 Select File 2 Select Open 3 Navigate to folder that contains data layer 4 In files of type: select MapInfo (*.tab) 5 Select data layer 6 Select Open 6 4 (Continued on next slide)

  4. How to display a data layer & control display characteristics in MapInfo: (continued) To change the display characteristics (line width, color, fill, etc)- 1 2 • 1 Select Map • 2Select Layer Control • 3 Select Display 3 (Continued on next slide)

  5. Layer control: Display (continued) 4. Change the characteristics: Fill- (pattern & foreground) Border- (style, color, & line width) see the sample changes, select OK> OK & the results will display on the map:

  6. 1 select 2 How to label a data layer using a field value in MapInfo: (Layer Control: Label) 1 Select map 2 Select layer control 3 Highlight the layer that you wish to label 4 Select label 3 4 Layer control:Labeling (continued on next slide)

  7. 5 6 9 7 10 Layer Control: Labeling (continued) 5. Choose the field to label Select the label characteristics: 6. Visibility 7. Style-select text button ( 7a. text color, size, background, effects) 8. Select OK 9. Position of text & offset from centroid 10. Select OK 7a. 8 Layer control:Labeling (continued on next slide)

  8. Labeling (continued) 12 12. From layer control, select (place a check mark for the layer) in the Auto Label box 13. Select OK and view the results( labels on map): 13

  9. Display multiple layers on the same map view: Select File >open, you can open more than one data layer at a time: 1 2 3 1 Select File 2 Select Open 3 Navigate to folder that contains the data layers. Be sure that “Files of type:” is MapInfo (*.tab) 4 Select data layers by pressing Ctrl key & selecting layers 5 Select Open 4 5

  10. Display multiple layers on the same map view: Select file >open, you can open more than one data layer at time can be displayed at the same time using map> layer control>display. The following is a result of opening 3 data layers in the same view and changing the display characteristics to distinguish each layer:

  11. What is a Workspace in MapInfo? A workspace is a set up file that saves: - current settings of all open tables - style characteristics such as color, line width, text style, etc. - map scale or view - print layout settings Why is a workspace important or useful? - Workspaces save you time by remembering all tables that are open and all of their properties. Later, you can open a workspace and not be required to open all the tables and recreate the characteristics of each data layer. How do I create a workspace: - After opening layers, setting display characteristics, Select File> Save Workspace type new name of workspace How do I open a saved workspace: - Select File> Open> in Files of Type box> select Workspace Select the workspace to open- (filename.wor)

  12. You are now ready to begin MapInfo Exercise- Lab 1 • Layer Characteristics. The main objectives are: • Open different views of data (map, browser, & graph) • Change display characteristics of a data layer • Display multiple data layers • Label attribute (field) values of a data layer on the map • You will also use some of the main button tools such as • magnify tool • grabber tool • the information tool (i) • Save a workspace • Begin exercise- lab 1
