Fugro Geospatial was tasked by the Northwest Arkansas Planning Commission to generate topographic contours from lidar data collected over Washington and Benton Counties. The project area covers 1315 square miles and includes all of Washington County and the following jurisdictions in Benton County: Avoca, Bella Vista, Bentonville, Cave Springs, Centerton, Farmington, Fayetteville, Gentry, Greenland, Johnson, Little Flock, Lowell, Pea Ridge, Pea Ridge Military Park, Rogers, Siloam Springs, and Springdale. The lidar data was collected by Fugro in two separate projects. The Washington County lidar was acquired between January 5 and 24 2015, and the Benton County lidar was acquired between December 2 and 4, 2015. Lidar data collection was performed with a twin engine aircraft, utilizing a Riegl LMS-Q680i sensor; collecting multiple return x, y, and z as well as intensity data. Specialized in-house and commercial software processes the native lidar data into 3-dimensional positions that can be imported into GIS software for visualization and further analysis. The horizontal datum for the data is the North American Datum of 1983 (NAD83, NSRS2011) and the vertical datum is the North American Vertical Datum of 1988 (NAVD88).<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "geometryType": "esriGeometryPolyline", "sourceSpatialReference": { "wkid": 102651, "latestWkid": 3433, "vcsWkid": 105703, "latestVcsWkid": 6360,
