Data are collected through automated process and interagency data exchange. Data are provisional and subject to change. The PDF graphical plot version is a higher quality product which requires the free Adobe Reader (see note below). PDF graphical plots also allow user to "zoom in".
Note: Graphical Plots are in "Portable Document Format (PDF)" and require a PDF viewer to be viewed. Viewer should be installed in your local computer before you can view the documents directly. PDF files may also be downloaded to your PC and you may use the PDF viewer as a stand alone product without the browser.
