Contour lines and spot elevation points are derived from 2020 LiDAR data.<o:p></o:p>Dataset is large and takes several hours to download. Consider connecting to the service, downloading a subset of the data through the feature service, or download a prepackaged file geodatabase with the topographic and planimetric data that covers a section (https://mclio.maps.arcgis.com/apps/webappviewer/index.html?id=84c7b8d95af04cdda6b0c2ae26590531). For a countywide dataset, please download the file geodatabase available here:https://www.dropbox.com/s/odwa17nzcvowwdf/Topographic_countywide.gdb.zip?dl=0 Performance can vary. If the contour lines are only being used for reference and you don't need the actual vector data, consider using the cached service (https://lio.milwaukeecountywi.gov/arcgis/rest/services/Topographic/Topographic_Cached/MapServer/0).
