The Planning Application documents are stored in Tagged Image File Format (TIFF). This is a standard high quality image type that is commonly used for images that have a lot of detail and perhaps may need to be altered (as plans often do).
Most documents have multiple pages and require the use of a multi-page capable TIFF viewer to be effectively displayed. While numerous TIFF viewers are available, not all are capable of reading multi-page TIFFs (some viewers display only the first page).
If you are running Windows, you received a multi-page TIFF viewer as part of the Windows installation. Depending on the version of Windows being used the TIFF viewer is named, KODAK Imaging or Windows Picture and Fax Viewer.
If you are using any other operating system or browser, check your user manual or with a technical consultant regarding an appropriate TIFF viewer for your system.
