BIOL 1309: The Nature of Cancer

Using & Accessing PolicyMap

Importing External GIS Data Sources into PolicyMap

PolicyMap has data sources and data points built right into the application, and includes cancer data, health information and a variety of demographic data options that should meet the needs of most students.

If you would like to add data to PolicyMap from an outside source be aware that it will need to be “cleaned” with the appropriate geolocation information.  Spreadsheet data must contain columns containing labeled fields using the actual words “Address”, “City”, “State”, and “Zip Code”, or latitude and longitude coordinates in decimal format only. Also, files must be saved as CSV (comma delimited). Please refer to the following information below or access the PolicyMap help guide for complete instructions on setting up your import data files.

Requirements for Importing

  • Address – This primary address column should contain only the street number and full street name including St., Blvd., etc., and any directional information such as N, S, NE, etc. Do not include unit or apartment numbers in this column.
  • Address2 – If the address has an apartment, suite, or unit number, put it in this column. This does not have an effect on geocoding and can be displayed for the address later.
  • City – City name.
  • State – Standard state postal abbreviation.
  • Zip code – 5-digit zip code. At this time, we cannot locate points on a map using the zip+4.
  • Latitude & Longitude – If you happen to already have the geocoded information for an address(es), the coordinates must be in decimal format not minutes and seconds.

Limitations for Importing

  • Files cannot have more than 10,000 rows (9,999 addresses and 1 header)
  • Files cannot have more than 45 columns of data
  • Header columns can have up to 50 characters 
  • Text Fields can have up to 250 characters
  • Must be in CSV Format
