Thematic Mapper

Visual map analysis is an art that is easily mastered in LandVision™. Thematic Mapper is a powerful tool that enables you to visually distinguish the important attributes of your data. The value of your data increases as trends and insights become visible on the map.

Classifying Data Overview

Once you import a data set into LandVision™, you can work with it as a layer. You can style the visual attributes for a layer (i.e.; fill color, opacity, image type, image color, image size, etc.) in two primary ways: unclassified and classified

  • Unclassified Data: When you first view your data in LandVision™, it is unclassified. Unclassified data means the style doesn’t vary at all even though the field values do vary. Leaving them unclassified would mean all the polygons would be the same color.

  • Classified Data: Classifying your data allows you to define a variety of styles for your fields, depending on the values contained in that field. For example, if you have Neighborhood polygons for an area, you can classify that layer and have the fill color tied to neighborhood name. Because each neighborhood has a different name, each neighborhood polygon would show as a different color.

Styling Data Overview

The Style Editor enables you to style the visual attributes of unclassified data, and the Ramp Editor enables you to classify your data, and define style rules for your classified data.

To style the visual attributes of unclassified data, use the drop-down menus on the left side of the Style Editor. In the example to the right, red fill color is being changed to blue from the Fill Color menu.

To open the Ramp Editor so that you can classify an attribute of your data, such as Fill Color, click the Ramp button to the right of the attribute.

To open the Style Editor, see Creating a New Style below. The Style Editor includes these features:

  • Style drop-down menu: Select a style to tie to your layer (data set) and/or edit. The menu lists all available styles for your layer. All layers are created with a style named Default, which is automatically saved in the User folder. The first time you work with a layer, the only style available in the drop-down menu is Default [USER].

    Note: To select a style using a path, click Other… on the drop-down menu.

  • Create New: Create a new style.

  • Copy: Copy the style displayed in the Style drop-down menu, and create as a new style.

Tip: To scroll through the styles in the Style drop-down menu one at a time, use the up and down arrow keys on your keyboard.
