Making a Map
Search the Map
To start, you should specify a location. The location box above the maps allows you to quickly find and position the map to different places.
- By Location – The default search is by Location, so enter an address, city, state, zip code, etc in the entry box and hit Enter/Return on your keyboard or click the magnifying glass icon.
- If searching by a type of geography, like Philadelphia, you will see the map position itself at the location you entered, with a border surrounding the geography. If more than one location in the US has the same name, the map will default to the largest populated location, and a box will appear listing all matching locations by population.
- If you are searching by an address, the map will zoom to the address and drop a pin.
- By Pre-Defined Geography – Use the drop down menu in the Location bar to search for specific geographies. For example, if you want to find a specific census tract, start by selecting Census Tract from the drop-down menu. Simply enter the FIPS code for the tract and hit Enter/Return on your keyboard or click the magnifying glass icon.
Viewing the map – You can zoom in and out by double-clicking the map, using the scroll wheel on your mouse, or using the +/- buttons in the bottom right of the map. To pan the map, select and hold your left mouse button then drag the map within the map window.
Adding Data from Search
The Search Data field allows user to use keywords or a grouping of words to find the data that is available on PolicyMap.
- The top of the results bar will show the total number of matches for the keyword. If the results do not match the data you are looking for, try to add additional words or specific keywords.
- The results will show the data title, where to find the data in the category, and the source of the data. Mouse over the icon to see the data description.
Info and Mouse-Over Bubbles
When a data layer is added, users can mouse-over a geography to see the values.
Select a location to open the Info Bubble. This will show the value of the current geography as well as the benchmark for the larger geographies the location is contained in. If there are multiple years for the data, users can view the values of the years by mousing over the trend chart.
Select the See Full Chart to view a trend chart of available years, and compare the benchmark geographies.
Data Layer Legend
After adding a data layer, the Data Layer legend will display the data title, Year, Variable, Range Values, etc and the values for each color range on the map. The legend will give you the ability to fully customize the map by changing the year, how the data is displayed, or making your own custom shaded ranges.
Legends can be dragged to any location on the map. Select the bar on top of the legend to select, and then drag. The (-) symbol on the right will minimize the legend, which will be replaced by an (+) to maximize the legend.
Select the color range in the legend to isolate the range on the map. Users can select multiple ranges.
Data Points Legend
Data Points allows you to view point datasets, like addresses, on a map. You can view these datasets by themselves or on top of a data layer.
When you load a point dataset, the Data Points legend will appear. The legend will display what icon the dataset is represented on the map, the optional ability to search, and the filter points. Click on any icon to display information about that site in the info bubble.
