Research methods for improving satellite images based on Pan-Sharpening

Dorozhynskyy O., Obroslak R., Stusyak Y.

Geomatics, Landmanagement and Landscape

2015

no. 3

29--43

The authors of the article consider five classic methods to improve images with pan sharpening and it present their mathematical models and technological schemes, the estimation of their positive effects both on color distortion and fragmentation in spatial resolution. Results of impact methods were observed and compared in two sofware products: Erdas Imagine 10.0 and ArcGIS 10.2. For comparison were used satellite images with ultrahigh spatial resolution and high spatial resolution.

Determining the influence of the earthquake on the change(s) of objects using remote sensing data

Chetverikov B., Babiy L., Dorozhynskyy O.

Geomatics, Landmanagement and Landscape

2013

no. 3

7--15

Two methods of determining changes of objects (structures) using remote sensing data obtained in different times are considered in this article. The comparison of the percentage of destroyed buildings as a consequence of the earthquake in L'Aquila city (Italy) was implemented. For comparison two ways of data collection were used: obtaining data by the digitalization of objects before and after the disaster (using MapInfo software) and by automatic image classification using a special module Delta Cue (Erdas software).
