Description: <p><span style="background-color:rgb(255,255,255); color:rgb(36,36,36); font-family:Arial; font-size:14.6667px;"><span style="font-style:normal; font-variant-caps:normal; font-variant-ligatures:normal; font-weight:400; letter-spacing:normal; text-align:left; text-decoration-color:initial; text-decoration-style:initial; text-indent:0px; text-transform:none; word-spacing:0px;">This feature layer represents milepoints, the linear measurements along Kentucky’s road system, spaced at whole-mile intervals. Milepoints serve as a general linear referencing system used to locate roadway characteristics and events. Each milepoint is recorded as a decimal number calculated to three decimal places (thousandths of a mile), or just over 5 feet. All routes in the Highway Information System (HIS) have an inherent topology or directional flow, which is assigned when the route is entered into the system and can be visualized in a GIS program. For divided highways, topology always follows the direction of flow. A cardinal route’s topology always aligns with the cardinal direction, while a non-cardinal route’s topology follows the non-cardinal direction. For interstate highways and state parkways, milepoints start at 0.000 at the beginning of a route—either a state border or the route’s starting point—and increase in the cardinal direction (typically north or east). When a new route ID is assigned at a county line, its starting milepoint matches the highest milepoint of the previous county, meaning not all interstates and parkways begin at 0.000. For all other state-maintained routes, milepoints reset to 0.000 at each county boundary and increase in the cardinal direction until the route ends within that county. In cases where a route begins at a higher-classified roadway (e.g., a county road intersecting a US or KY route), the topology points away from the higher-classified road. A road’s milepoints always increase in the direction of its topology, which is why non-cardinal routes have beginning milepoints that are higher than their ending milepoints. This dataset supports transportation planning, roadway analysis, and event location tracking across Kentucky. Milepoint references in this dataset do not represent the physical locations of posted highway signs. Sign placement is as approximate as possible and may differ from actual whole-mile interval designations in this dataset.</span></span></p>
