How to Make a Map with Point Aggregation

This is a step by step guide from start to finish for Creating a Spatial Lens Boundary for Region Mapping and Creating a Map Visualization using Point Aggregation. The current Point Aggregation methods available are Region Maps and Heat Maps. There are links to full guides on those sections included in this guide. 

If you intend on creating a Heat Map the Spatial Lens section of this guide is not necessary.

The first section of this guide on Adding a Spatial Lens is intended for users with the Administrator permission level. Users with other permission levels can follow all steps from the Creating a Map Visualization with Point Aggregation section. 

If you feel like you should have access to these areas of your site please contact your site administrator.

After that for Creating a Map using that Spatial Lens, you can follow this guide for Creating a Map Visualization. The section under Point Aggregation would explain specifically how to add the Region Map information or Heat Maps. 

1. Navigate to the Dataset you are wanting to use.

2. Under the Visualize Menu, select Create Visualization.

3. From the visualization screen, select the Map option.

4. After that selection, Navigate to the Menus on the left-hand side. Select the Point Aggregation Menu.

Note: There is a chance you may need to reconfigure your Geo Column if the correct column is not automatically selected.

For Region Maps, select the Region Map radio button then select the Region Map you wish to use. You will also need to select what you would like to show in those regions using the Measure option.

Note: You are not able to make a Region Map based on a Filtered View of a dataset.

For a Heat Map, you would select the Heat Map radio button.

5. From here it depends on what other options you are wanting to configure. The guide will have more information. If there is nothing else you can select the Save Draft button in the bottom right-hand corner.

6. You will need to give a name for your visualization and after you set your name click Save.

7. Next hit Publish in the top right. 



8. The final step is to select your view permissions and hit publish. They will be set to the same view level as the base dataset your map is built on.

If the base dataset is public, it will appear as follows.

If the base dataset is Private, the following message will appear: "This asset will be made Private, as it derives from a dataset that is Private."
