SLIP subscription maps and services require you to register for a free account to use them.
Public services and maps do not need a SLIP account. You can simply click to open SLIP maps, or copy and paste SLIP service URLs into your GIS or other application. However, if you would like to download this data you will need to create a SLIP account when prompted.
Once you have registered to access SLIP subscription maps, you can request access to the maps and datasets by following the prompts when you try to access them.
