MARPLOT 4.x users: MARPLOT 4.2.3 requires 2010 TIGER files (county-level roads, rivers, etc.). The installer will give you the option to delete any previously downloaded 2007 TIGER files. If you install the program and map data to the same locations as your current MARPLOT, you will not need to transfer any data. However, it is recommended that you make a backup copy of your MarplotMaps folder before running the installer. After installation, use the Download Manager to download new 2010 TIGER files for counties of interest. You may also want to select the "Check for Updates" option in the Help menu to see if other files (such as state census blocks) need to be updated.
MARPLOT 3.x users: If you're using a version of MARPLOT prior to version 4.0, you should follow the guide for updating to MARPLOT 4.x from a 3.x version of MARPLOT. To retain your current MARPLOT maps and data, please read this document before installing MARPLOT 4.2.3.
