Guidelines for digital plat submittal
- An ASCII point file is not required when a DXF or DWG file is provided.
- AutoCAD 2004 (and newer) format files are NOT being accepted. Please save to an older version.
- Drawings should be two dimensional, not 3D (all Z values should be 0).
- Drawing files should be on state plane coordinates (rotated to grid, scaled to ellipsoid), rather than on a local surface datum with ties to state plane control annotated.
- Lot numbers and street names are required.
- Only access easements are used in the GIS. If you include other types of easements (utility, snow storage, view corridor, etc.) please identify them as such.
- Bearings, distances, certificates, notes, and other annotations are not required.
- Files may be emailed to gis@tetonwyo.org or provided on floppy disk.
- Line trimming at ends to create hollow point symbols should be avoided. This is a bad practice for any digital data exchange.
- Digital plats are required even when state plane coordinate ties are not.
- Do not put a plat on state plane coordinates unless you really surveyed the control in (do not use the GIS to get your coordinates).
- Alta is on HARN, the rest of the County is on NAD83.
