Specifications include, but are not limited to: i.Video Inspection: High resolution, real-time flight video, with vertical or oblique camera angles. ii.Orthophotos: Seamless mosaic of aerial photos with resolution of approximately 1-2 inches per pixel. iii.Distance, Area and Volume Measurements: Based on a high-resolution 3D reconstruction of the survey area, produced by applying photogrammetric algorithms to the photo array. iv.Imaging Products: The use of multispectral imaging sensors is highly desirable (in particular near-Infrared) for the primary purpose of determining pervious vs. impervious surface coverage as well as surface temperature profiles. v.AutoCAD Drawings: Orthophotos, contours, or 3D mesh surface, in native CAD formats. vi.GIS Data: ESRI file geodatabase or shapefiles/rasters compatible with GIS platforms. vii.GeoHECRAS Calculations: Stream cross-sections, streambank elevations and configurations, flow calculations, in formats compatible with GIS and CAD. viii.Drone-Enhanced Ecological Assessments
