Methods of creation and practical application of mask -maps of high-level terrain objects at orthotransformation of digital aerial photographs

Aim. To develop and accomplish an experimental testing of the method of creating a mask map of high-level terrain objects. Methodology. On the basis of the cross-correlation method, it is proposed to carry out the estimation of the similarity of orthophotos that have a mutual spatial overlap. The comparison of the left and right images takesplace in pixels, for pixels with the same spatial coordinates X and Y, and therefore, there is no need to organize the movement of the search bar and to search for the corresponding points as such.

Application of mathematical morphology methods in terms of erosive processes research using aerial photography materials

Object of study. Planned distribution establishment of erosive “spots” of the agricultural lands is based on the processing of binary images of aerial photographic materials using morphological and planimetric methods of analysis. Methodology. Offered methodology is based on the non-linear operators’ application.

Method of preparation large-scale plans for the material aero and surface capture

It is proposed the technological scheme of creation of large – scale plans in hilly and mountain terrains using two kinds of materials: aerial survey implemented in the past and modern digital phototheodolite survey. The profitability of methodology for creation of plans for small territories is underlined.

 

Technology for building digital elevation models for creating plan of river floor

It is represented method of construction of Digital Elevation Models of river bottom. Measurement were executed double-frequency echo sounder data processing was conducted with the use of DPS “Delta”. Accurasy of DEM corresponds to the scale of topographic plane 1:5000.

 

The use of unmanned aerial vehicles for estimating market real-estate value

The Purpose. The problem of applying unmanned aerial vehicles for real estate estimations has become important with the development of modern methods of distance sensing of residential areas. For several decades aerial photography has been an effective tool for performing geodetic survey, geophysical studies, and various types of monitoring. Modern technology used in creating topographic and cadastral plans is based on using digital data of aerial photography [Burshtynska H., Stankewych S., 2013].
