Located in the heart of the Florida Panhandle, the county is teeming with approximately 225 square miles of natural, forest and wetland habitats. Included in Tallahassee, an additional 105 square miles of urban Tallahassee. Florida State Capital, two State Universities, tree-lined canopy roads, and old-Florida plantations. Centuries-old yellow pine and palmetto flatwoods, hardwood hammocks and deeply incised ravines, along with magnolias, and grandfather live-oak trees line the scenic canopy roads through the county, and rolling hills characterize the urban, Tallahassee landscape. For obtaining accurate LiDAR data, it is a challenge to say the least. http://www.pobonline.com/articles/102258 Mon, 21 Sep 2020 09:00:00 -0400 https://www.pobonline.com/articles/102258-reverse-engineering-brings-digital-data-to-life http://www.pobonline.com/articles/102253 Wed, 16 Sep 2020 09:00:00 -0400 https://www.pobonline.com/articles/102253-how-to-use-drones-for-equipment-monitoring-and-inspection http://www.pobonline.com/articles/102252 Tue, 15 Sep 2020 09:00:00 -0400 https://www.pobonline.com/articles/102252-five-reasons-land-survey-firms-invest-in-drones Familiarity with surveying led Jaquess to create a photo management platform for surveyors.

In this example, color shading of the LiDAR elevation data is used to illuminate old and abandoned channels formed by the Skagit River. These historic patterns help identify the Channel Migration Zones, which are areas where the river may be expected to move again in the future. Skagit County is a partner with the Washington Department of Natural Resources 2016 LiDAR project. Most of the county was flown collecting high resolution LiDARdata.
