Welcome to another MapReveal™ Software Community Post!
In today's post, I will show you how you can create Individual Value Thematic maps on MapReveal™ Software. Thematic maps serve as visual representations of location-based attributes. These maps help gain a deeper understanding of the relationships between various features and reveal spatial patterns within the data.
Categorized styling is based on discrete values of an attribute that determine how each feature will be rendered. This is extremely useful for visually representing qualitative or nominal data, such as land use, soil type, or administrative boundaries. They are also quick and easy to create.
For this example, I have a sample dataset of block groups in the SF County area with the attributes as shown in the snapshot below.
My goal here is to create an individual themed map using the column 'composite_crime_category', which represents the composite crime index for within State comparison based on all crime types.
I can simply 'drag-and-drop' this table to my Map Session. By default, MapReveal applies 'Fixed Styling' to the uploaded files, which appears like this.
The uploaded dataset will also appear as a layer in the Layer Panel. You can then click on the Layer to expand the Styling Panel. Under Styling Types, a dropdown menu has been provided which allows you to select the styling type that you want to apply to the layer.
Once you choose 'Categorized Styling', you can select the attribute of interest –'composite_crime_category'
Next, you can use the 'Add New Condition(s)' button to select the unique values that you want to use for creating the thematic map.
You will notice that all the unique values of the attribute will appear, which can be selected using the check box provided. This column has the following unique values - low / below average / above average / high / highest. There is also an option to 'Select all' unique values.
Once the selection is completed, you can specify the 'Fill' and 'Label' styling parameters, which will be the global setting and will be applied to all the categories selected in the previous step.
Once completed, you will observe that each category has been assigned a unique color which also appears in the form of a Legend within the Styling Panel.
You also have the option to change the look and feel of the individual categories using the 'edit' button available next to each category. There is an option to delete the category as well. Deleting a category applies the fallback styling to the underlying features.
Once published, this is how the map appears.
On the legend, you will notice that the dropdown next to the Layer can be used to expand the categories that you have created. The visibility of the individual categories can be toggled using the show/hide icon next to each category. You can click on the category to highlight the underlying features and also to pan and zoom the map into the respective category extent.
I hope you found this useful. Do share your feedback/questions in the comments section.
