ABSTRACT
Hydrography layers for the study area covered by Map 24–09.0: Hydrography map showing automated stream permanence identification for the Catawissa 7.5-minute quadrangle, Columbia County, Pennsylvania. The vector data herein were derived from the most recently available Quality Level 2 (QL2) lidar data using geomorphon analysis and least-cost analysis. These data are a subset of the larger Pennsylvania Hydrography Dataset (PAHD), which is in the process of being generated. They were produced using QL2 lidar deliverables and most will have a minimum horizontal accuracy of 1 meter and a minimum vertical accuracy of 0.5 meter at a 1:2,400 scale. This geodatabase contains a dataset of derived hydrography features of the Catawissa quadrangle as well as field validation points collected in the study area.
