Updating Inventory Using Oblique Videogrammetry and Data Fusion
Abstract:It is often necessary to make a tradeoff between the cost of generating a new inventory and the need for up-to-date information to facilitate management. Yet, in some cases, only specific areas need to be updated. Here we introduce a system for fast, cost-efficient inventory update that fuses oblique video with GIS-based data. The oblique view also serves to reduce the issue of cloud cover, makes interpretation easier, and enables nonstereoscopic aerial measurement of height. Tests indicate that the data produced compare favorably with high-resolution orthoimagery.

- The Journal of Forestry is the most widely circulated scholarly forestry journal in the world. In print since 1902, the Journal has received several national awards for excellence. The mission of the Journal of Forestry is to advance the profession of forestry by keeping forest management professionals informed about significant developments and ideas in the many facets of forestry: economics, education and communication, entomology and pathology, fire, forest ecology, geospatial technologies, history, international forestry, measurements, policy, recreation, silviculture, social sciences, soils and hydrology, urban and community forestry, utilization and engineering, and wildlife management. The Journal is published bimonthly: January, March, May, July, September, and November.
