GeoLytics: How to Map

Learn how to navigate, analyze, and visualize U.S. Census data using GeoLytics web applications.

Methods of Mapping GeoLytics Data

There are three ways to quickly map GeoLytics Data: Online with GeoLytics, using geographic data with ArcGIS, and using Attribute data with ArcGIS. Each of these methods are listed below.

For more advanced instruction, consider attending a library workshop or taking one of many GIS courses on campus.

Online with GeoLytics

Create a Map with GeoLytics Online Demographic Data:

1) When you are setting your census data parameters, check the Map (web) button under Report Type.

A screen capture of the Geolytics interface. The first text bubble points to the "Report Type" drop down menu and reads: A. Click on report type. The second bubble also points to the "report type" drop down menu and reads: B. Select the report type you would like.

 

2) Click Screen capture of the "Run Report" button on the Geolytics interface from the left-hand navigation to process the request.

 

3) Right-click the map image to bring up a menu. Click on Save image as... then type in a name for the file. Click Save to save the image in png format.

Geographic data using ArcGIS

Download a shapefile (.shp):

1) When you are setting your census data parameters, check the MAP button under Report Type.

A screen capture of the "Report Type" drop down menu. The options are as follows: CSV (Comma Separated Values File without header), CSV (Comma Separated Values file with header), DBF (DBase III), Map (DBase III with shape file), MIF (MapInfo Interchange Format), Data (web) (Online data report), Map (web)(Online map report), Summary (web)(Online summary report), SUM (Summary report). MAP is selected.

 

2) Click Screen capture of the "Run Report" button on the Geolytics interface from the left-hand navigation to process the request.

 

3) A Download status page will open in a separate window. If the download does not start automatically, click on the .zip file to download and save it manually.

Screen capture of the contents of the zip file once it has downloaded. There are four files: Noname2 (SAS Output), Noname2.dbf (DBF File), Noname2.shp (SHP file), Noname2.shx (SHX file). Noname2.shp is highlighted.

 

See Esri's How-To page for detailed instructions on how to open and manipulate .shp files in ArcGIS Pro.

Note: The download steps above also apply for obtaining maps in Interchange Format (.mif) for use with MapInfo.

Download data (.dbf)

1) When you are setting your census data parameters, check the DBF button under Report Type.

A screen capture of the "Report Type" drop down menu. The options are as follows: CSV (Comma Separated Values File without header), CSV (Comma Separated Values file with header), DBF (DBase III), Map (DBase III with shape file), MIF (MapInfo Interchange Format), Data (web) (Online data report), Map (web)(Online map report), Summary (web)(Online summary report), SUM (Summary report). DBF is selected.

 

2) Click The "Run Report" button in GeoLytics from the left-hand navigation to process the request.

 

3) A Download status page will open in a separate window. If the download does not start automatically, click on the .dbf file to download and save it manually.

A DBF file in the downloads folder

See Esri's "Join Attributes from a Table" section from the "Joins and relates" page for detailed instructions on how to join these .dbf files with geographic data in ArcGIS Pro.

 

Note: The above download steps also apply for obtaining data in Comma Separated Values (.csv) format.
