Import CSV Points

Use this tool to import a list of point locations from a spreadsheet.  Most spreadsheet programs like Microsoft Excel can export their data to a CSV file.  In order to import this data into the map your data must be organize such that each row is a record and the first row must contain column names. 

Required Columns
Your CSV file must contain two columns that define the latitude and longitude of each point.  The column names must match one of the following combinations
  • Latitude, Longitude
  • Lat, Lon
  • Lat, Long

    Alternate Coordinates
    If your CSV file contains projected coordinates such as UTM or state plane then those coordinates must be in column names matching one of the following combinations
  • X, Y
  • Easting, Northing

    Before you run an import containing projected coordinates you must first zoom the map to the approximate area where the points will be added.  This will help the system automatically determine the correct projection to use when interpretting these coordinates.  This step is not necessary when importing CSV files containing latitude/longitude coordinates.

    Create a new layer 
    A new layer is created in your map and all the CSV records are imported to it.  This is the most common action.

    Replace an existing layer
    Use this action if you are re-importing.  For example lets say you previously imported a CSV file from your GPS device containing 50 valve points.  Since then you have collected 100 additional valve points but you didn't clear out the original points from your GPS and so you now have 150 points to import.  You don't want to append these features to your existing layer because that will result in 50 duplicates.  So instead you choose the replace option which essentially deletes the 50 records you previously imported and replaces them with the 150 records in the new CSV file.  Keep in mind that this also deletes any notes, pictures, or editing that you may have done to these original 50 records in the map.

    Append to an existing layer
    Use this action when you are combining multiple CSV files into the same layer on your map.  To do this, import the first CSV using the "create new layer" action.  Then import each of the other CSV's using this "append" action.  The import will match field names in the CSV to field names in the existing layer.  Any fields found in the CSV but not the layer will be automatically added to the existing layer's list of fields.
