Editor's Notes
- Click – talking about SCF
- SCF is designed as a central point of access to over 220,000 geodetic control stations and PLSS corners in Wisconsin. Layers of control are NGS/HMP, COUNTY, USGS, CORS, and PLSS corners CLICK = Two views, terrain and satellite CLICK = Search: roll mouse to zoom in OR by the SEARCH upper right corner for a location/address OR select by county OR T/R/S
- NGS = 7479 HMP = 8695 CLICK = COUNTY CLICK = USGS = 8673 CLICK = CORS = 131 CLICK = PLSS = 193,861
- Use the dashed box to select multiple records Become highlighted Displayed with number of records selected by category; click on arrow to view individual records CLICK = from here you click the “i” to open the record
- Selected HMP station CLICK = View full record CLICK = retrieves datasheet directory from NGS database
- Opens the attributes record CLICK = online data sheet; retrieves datasheet directory from NGS database
- The county is the custodian for PLSS corners within its boundaries. Progress towards updated PLSS monuments and coordinates varies widely across the state, with some counties having completed remonumentation with survey grade coordinates, while others are at various stages of completion. CLICK = As mentioned earlier, we’re showing close to 200,000 county PLSS records across the state; of those close to 62,000 PLSS corners have coordinates with “survey grade” accuracy.
- Only PLSS layer showing/select a point, then click to view record CLICK = to open record showing attributes CLICK = to open online tie sheet directly from county website/server
