Aerial Photo-interpretation of Natural Forests

Aerial photo interpretation for change detection of treeline ecotones in the Swedish mountains

New methods for assessing Marbled Murrelet nesting habitat: Air photo interpretation and low-level aerial surveys

This extension note summarizes the application of two new methods that were developed to assess the quality of forest habit that Marbled Murrelets (Brachyramphus marmoratus) use for nesting in British Columbia: air photo interpretation and low-level aerial surveys. Both methods use comparable sixlevel ranking systems that are based on the availability of forest attributes deemed important for n...

Unmanned Aerial Vehicle Instrumentation for Rapid Aerial Photo System

This research will proposed a new kind of relatively low cost autonomous UAV that will enable farmers to make just in time mosaics of aerial photo of their crop. These mosaics of aerial photo should be able to be produced with relatively low cost and within the 24 hours of acquisition constraint. The autonomous UAV will be equipped with payload management system specifically developed for rapid...

Change Detection for Aerial Photo Database Update

With rapid new technological development during the past 50 years, aerial photos have been increasingly and commonly used not only in geographic information systems but also in various spatially related applications. Many municipalities and government agencies have constructed aerial photo databases all over the world. Keeping these databases up to date is the most important part of making them...

The Suitability of Object-based Image Segmentation to Replace Manual Aerial Photo Interpretation for Mapping Impermeable Land Cover

Monitoring the sealing-over of the soil surface by impermeable material in urban environments is of great interest as a key indicator of sustainable land use. Many studies have attempted to automatically classify surface impermeability by using satellite or aerial imagery. Air photo interpretation (API) has been used as a method to verify their accuracy. However, independent accuracy assessment...
