Visual Orthophoto Classification Application
IOP Conference Series: Earth and Environmental Science, 2021 Abstract Data acquisition using remote sensing has opened up new possibilities of their analysis and application. For the ecological stability calculations, it is needed to divide the observed area into subsections based on the land character. The selection may be done by various kinds of processing. For example, it may be done manually,

AGG+, 2017 <p>A digital orthophoto map is an orthorectified photo mosaic that is a basis for a successful mapping. A digital orthophoto map is one of the basic products of today&rsquo;s photogrammetry and it represents its well-known and used product, and it was created based on the map users' wish to unite the detail and ...

An innovative use of orthophotos – possibilities to assess plant productivity from colour infrared aerial orthophotos [PDF]
Remote Sensing in Ecology and Conservation, 2019 AbstractStudies of ecological processes should focus on a relevant spatial scale, as crude spatial resolution will fail to detect small scale variation which is of potentially critical importance. Remote sensing methods based on multispectral satellite images are used to assess primary productivity and aerial photos to map vegetation structure.
