Pix4D makes software solutions for GIS progessionals. One of the solutions is the ability to generate 3D digital elevation models. This presentation will cover how a DEM can be exported as either a digital surface model (DSM) or digital terrian model (DTM). It will also cover how contour lines can be derived to represent the true bare-earth topography of a terrain. A demonstration will presented to showcase best practices for leveraging these 3D elevation products in your GIS workflow.
Description/Abstract: Northgate Environmental Management, Inc., in collaboration with GeoWing Mapping, Inc., performed an aerial survey of the Montezuma Wetlands Restoration Project, an approximately 2,400-acre dredged sediment disposal, management, and reuse site located in the Suisun Marsh in the San Francisco Estuary. The site was previously diked and drained for agricultural use over 100 years ago. The project will allow the placement and reuse of dredged sediments from San Francisco Bay to restore approximately 1,450 acres of intertidal marsh, seasonal and managed wetlands, and shor
