You can get access to the Thematic Map Wizard by opening a New File with choosing Thematic Map as a map type or by clicking Create with Wizard... in the Thematic Map menu. It opens the start page of the wizard with an overview of the six steps to create a thematic map.

Welcome Page

Add a new theme

Choose the Add new theme to the map option and enter a name for the theme (ex. population change). It is possible to load the wizard settings with the load settings from xml file option if you have already created thematic maps with the Thematic Map Wizard. The xml file can be choosen with the ... button.
hintA map can have more than one theme (ex. choropleths + proportional symbols).
hintThe next button is only active if a theme name is set.

Modify an existing theme

This option should be used if you want to change the settings of an existing theme in your map.

Step 1 - Statistical Data

  1. Load statistical data from file
    hintThe format of this file can be *.xls, *.csv, *.dbf or *.txt.
    hintThe statistical data should be complete and accurate, which means that all the fields should contain the necessary information.
    hintIt's possible to check the table with the ThematicMapLenseIcon.PNG lense icon.
    hintThe statistical data should have a common field with the attribute table of geometry data, in order then to be joined.
  2. Select attributes to visualize either with selecting selecting them and pressing the [>]-button, double click or drag and drop.
  3. Define if the values are absolute or relative, the map shall be classified and how to visualize the theme.

Step 2 - Geometry

  1. Load a geometry data from .shp file.
    hintIt's possible to either watch the data in tabular form or to get a map preview.
  2. Set map scale and map size.
    hintBy default map scale and size are linked, but it's possible to deselect them ThematicMapConnectIcon.PNG. The Icon is blue if it's inactive.
  3. Pick a coordinat system.
    hintIt automatically picks the selected coordinate system of the Ocad-map.

Step 3 - Join Data

  1. Pick a common field of both tables.
    hintIf you aren't sure which fields have common values, you can use the ThematicMapLenseIcon.PNG lense Icon to check the tables.
  2. Decide if all records shall be kept or only the matching ones.

Step 4 - Visualization of map's theme

Phase 1

Decide which visualization method is suitable for the chosen data. The wizard suggests the most appropriate method(s) according to the choices done in Step 1.

Phase 1.5: Only for divided charts

  1. Divide the attributes to several groupes by clicking on the [...]-button and opening the Create Groups with Drag and Drop window.
    hintOnly available if multiple elements of the same attribute are choosen.
    1. Select the amount of groupes.
      hintEach column is one group.
    2. Sort and creat the groups with drag and drop.
      hintOnly logical group settings get shown and are to be picked.
    3. Click on Close to use the current setting.
  2. Define the proportionality of the chart elements.
  3. Define the amount emphasis.
  4. Make your choice out of the available charts.

Phase 2

  1. Decide which visualization type shall be used.
  2. A double click on the attribute(s) opens the color picker and allows to change the coloration either with CMYK or RGB.
  3. Define the scale, minimum height and bar width for the visualization.
  4. Define the stroke setting.
    1. Click in the color box to open the color picker and select a color.
    2. Define the stroke width and decide if the stroke shall decrease for small symbols.
    3. Decide if 0 values and no data shall be shown.
  5. Define the opacity.

Step 5 - Visualization of Basemap

This step shows the different layers and can be edited and arranged. Additional layers can be added ThematicMapAdd.PNG and removed ThematicMapRemove.PNG.
hintMake sure that the basemap features are suitable for this scale.

Step 6 - Additional Map Elements

Additional map elements help the user to read the map.

  1. Set a map title.
  2. Decide if any legends shall be added.
  3. Decide if a scale bar or a scale text shall be added.
  4. Decide if you want to add any additional text information.

Create Thematic Maps with XML Script

OCAD XML scripts functionality does also support to create thematic maps with xml script

Thematic Map Samples

There are several sample maps available in the OCAD program folder (-> Samples -> ThematicMapper) as well as statistic data samples, geometry data samples and XML script samples.
hintOpen sample maps by using Open Sample Maps... in the File menu.
