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.
