GIS Data Download
FTP Site (GIS Download Only)
FTP site INSTRUCTIONS
To view GIS layers, look up land information, and print maps, please use the GIS Web Map.
To download GIS data, follow the FTP site link provided below and enter the username and password in the pop-up credentials box. GIS data is organized by folder and can be downloaded by clicking on the files. Please note that large file sizes may cause the connection to be dropped. For this reason, it’s helpful to use an FTP connection with a resume feature.
We are also aware that some browsers may not support FTP anymore. If trying different internet browsers does not work, you can also connect via CoreFTP software. Or if you use Windows, there is an FTP client built into the operating system, which you can access by copying the URL into the file explorer.
