UAVs / Drones
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
Drones are now becoming mature technology for data collection in agriculture, natural resources management, mining, facilities management, emergency response, and other fields. Working with drone data, however, is a non-trivial affair because it requires a special suite of knowledge and skills related to remote sensing, photogrammetry, spatial data management, spatial analysis, mapping, specialized equipment, and regulatory considerations.
GrandView Services, LLC, in conjunction with Cal Engineering & Geology has been using drones for the past few years to develop data collection through photogrammetery software. Heller Gregory is a licensed pilot with a Part 333 exemption through the FAA. The FAA currently requires a Part 107, a simple test through the FAA.
After the first year of research & develpment, GrandView Services, LLC is putting the data to good use. We've had several large projects with the City of San Ramon and the City of Lafayette. Our latest client has been Trail People.
The unmanned aerial vehicle (UAV) is undoubtedly emerging technology for spatial data collection. We acquired data from a UAV and a manned aircraft over the same location, and processed the data for orthomosaic production. We have assessed the data acquisition, photogrammetric processes with real-world examples for an informative evaluation for GIS users.
Advances in drones technology offer tremendous possibilities for applications in agriculture and natural resources management. Today's drones are easier and safer to fly than ever, and multi-spectral sensors have come down in size, weight, and price. However the jump from drone hobbyist to drone operator for scientific and resource management missions can be enormous.
Restoration projects aim to restore, enhance, or protect critical habitats for endangered and endemic plant and wildlife species. These projects are often funded through significant financial investments by multiple stakeholders, and also provide valuable ecosystem services through green infrastructure establishment.
