If you are interested in seeing a map that only includes the various types of assault, then the filter checkboxes can be used to filter the data and display the corresponding heatmap. Zoom into the Seattle area and view the heatmap. Change the name “Layer 1” to “Offenses.”Ĩ. Select the Heatmap Icon (4 th from left) under Data in the Layer panelħ. In the Height box, select “Count” as the aggregate function.Ħ. Drag the General Offence Number over to the Height box.Ĥ. From the Field list, drag latitude and longitude over to the Location box.ģ. To load the data into the map, select the 3D map icon in the Insert Tab.Here are the steps to creating the heatmap: Instead, we will proceed directly to creating a heatmap of the number of incidents, with the ability to filter by offense type. For our purposes, we won’t worry about doing the typical preliminary steps of data exploration or cleansing prior to generating the map. Now that the data is loaded, it is ready to use. In the Data Tab, when the Queries & Connections icon is selected, the Seattle_Police_Department Query will appear in the panel on the right. In the Import Data Form, Select the “Only Create Connection” radio button and check “Add this Data to the Data Model.”ĥ.
Note: if you select “Load,” the data will load into an Excel worksheet, but some of the rows will be omitted because Excel’s row limit is 1,048,576Ĥ. Select “Load To” from the dropdown box next to Load. After selecting “Import,” the following popup will appear. Navigate to the downloaded file and import.ģ. Select the “From Text/CSV” icon in the Data tab.Ģ.
To load the data into the data model, follow these steps: If you want to try this out on your computer, you can obtain the data from this link and export it to a CSV file for Excel. This data set has nearly 1.1 million rows, so it exceeds the limit of an Excel worksheet – and will require the use of the Excel Data Model. Let’s begin the process of creating a heatmap using a large set of publicly available incident data from the Seattle Police Department. Some users just need to install Power Maps, while others need an upgraded subscription or purchase of Excel. If you don’t see the 3D Map Icon, go to this link to learn what is necessary to obtain it. Power Maps can be accessed with the 3D Map icon, found in the Tours section of the Insert Tab. Since the data set is large, we will leverage Excel’s Data Model. The types of maps that can be generated with Power Maps are only limited by your imagination!Īfter covering the basics, we will demonstrate how to create a heatmap of police incidents in Seattle. This feature, called Power Maps, is now also available for Excel 2013.
One of the exciting new features of Excel 2016 is the capability to generate geographical maps.
