THEMATIC MAPPER


LandVision™ Help > Documentation > 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

LandVision Thematic Mapper Neighborhoods Unclassified

LandVision Thematic Mapper Neighborhoods 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. In the example to the right with the Neighborhood polygons, leaving it 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, as in the example to the right.

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 LandVisionButton_ramp.png 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.

LandVision Ramp Editor
Stepped and Smooth Ramps Overview

The type of ramp that you choose is an important part of the visual classification scheme of your data, and the effectiveness of your analysis. It determines the classification methods that you can select.

Stepped ramps are composed of individual color swatches. Each color swatch has a different value. The colors in smooth ramps are blended together.

Stepped ramps and smooth ramps have different classification methods:

  • Stepped Ramps: In the Ramp Editor, you must select a Classification Method and # of Classes for stepped ramps. There are four types of classification methods. Each method classifies data in a different way. Selecting the best method for your data set optimizes your data classification. The # of Classes you select determines the range of values represented by the individual color swatches of a stepped ramp. It is the best practice to select 5 to 7 classes for a stepped ramp. (See Tips on Classifying Data below for more information.)

    In the Ramp Editor, the Review and Modify Classes table populates based on your selected Classification Method and # of Classes. You can make modifications in the table if desired, such as changing individual colors of your selected ramp.

  • Smooth Ramps: Select a smooth ramp if you’d like to visually differentiate a wide range of values on the map. In the Ramp Editor, the Classification Method and # of Classes are grayed out. They do not apply to smooth ramps. The Review and Modify Classes table automatically populates with three color swatches, and the minimum, median, and maximum field values for your selected smooth ramp. You can make modifications in the table if desired, such as changing a color.


Stepped Ramps

For a Stepped Ramp selection, you must select a Classification Method and # of Classes.

Classification Method and # of Classes

  • Classification Method: Select Natural Breaks, Distinct, Quantile, or Equal Interval from the drop-down menuLandVision Thematic Mapper Class Method (See Tips on Classifying Data below for definitions and tips).
  • # of Classes: Select the number of classes from the drop-down menu LandVision Thematic Mapper Number Classes.

    Tip: The # of Classes sets the number of value ranges that have a distinct color. It is the best practice to select 5 to 7 classes. If you select too many classes, it is generally difficult to gain insight from the color scheme on the map. If you would like to visually differentiate many classes, use a smooth color ramp. (See Tips on Classifying Data below for more tips).


Review and Modify Classes Table

The Review and Modify Classes table enables you to try out different classification schemes before applying one:
  • Based on your choice of Classification Method and # of classes, the Review and Modify Classes table populates with the fill color, value, and label for your selected data field.

  • To further modify your classification scheme, you can make these selections in the table:
    • Color: Click on any ramp color to change it. The Color Selector opens (See Tips for Using the Color Selector below).
    • Value: Click a value to enter a new left end-point in the Edit Value window.
    • Label (Optional): Type a label for any data value. The Legend displays your label instead of the value.


To apply your classification scheme, click the OK button at the bottom of the Ramp Editor. The Fill Color button LandVision Thematic Mapper Button Ramp Color in the Style Editor displays your selected ramp.

Tips on Classifying Data


This section provides definitions and tips to help you optimize your data classification. The Classification Method and # of classes that you chose for your data can affect the outcome of your analysis.

Classification Method

There are four types of classification methods:

Natural Breaks
  • Divides data into classes based on natural breaks in the data distribution
  • Calculates groupings of data values based on data distribution and seeks to reduce variance within groups and maximize variance between groups
  • Limitation: Class ranges are specific to the data set, so it is difficult to compare a map with another map and to choose the optimum # of classes, especially if the data is evenly distributed


Distinct
  • The only classification method for fields containing text
  • Creates a separate class for each unique value in the data set
  • Limitation: if you have a large number of unique values in your data set, your thematic map will be difficult to interpret due to too many different symbols/colors


Quantile
  • Divides a data set that divide into "n" groups, containing (to the extent possible) equal numbers of observations
  • Desirable in that this method produces distinct map patterns and minimizes the impact of skewed data
  • Highlights changes in the middle distribution values because the intervals are generally wider at the extremes
  • Limitation: areas with similar values can end up in different classes while areas with very different values can end up in the same class


Equal Interval
  • Simplest method for classifying data
  • Divides a set of data values into groups each of which represents the same range of values
  • Better communicates trends with continuous sets of data. Works well with familiar data ranges such as percentages or temperature.
  • Limitation: not good for non-normally distributed data sets because you might get a map with many features in 1 or 2 classes and some classes with no features


# of Classes

It is the best practice to select 5 to 7 classes for a step ramp. If you select too many classes for a step ramp, it may be difficult to gain insight from the color style on the map. If you would like to visually differentiate a wide range of values, use a smooth color ramp.

Tips for Using the Color Selector


The Color Selector works the same for both Fill Color and Line Color, except that the opacity setting does not apply to Line Color. Each color has Red, Green, and Blue (RGB) values. The values range from 0 to 255. Fill Color has an Alpha value for opacity. Opacity value ranges from 0.0 (clear) to 1.0 (solid color). A color with 0.0 opacity is not visible on the map.

Tip: If you want to use the exact same color more than once, it is best practice to write down its RGB values. For Fill Color, also write down the Alpha value for opacity. In the Color Selector window, enter the values in the appropriate fields.
  • To pick a color using the Color Wheel, click on the wheel. To change the shade of the color, move your mouse in the box inside the wheel.

  • To select the opacity for Fill Color only, move the slider.
