Statistical analysis of utilization of Landsat data in observation of small inland water bodies

Spatial data are very important for assuring quality of decision-making. Satellite images are used in many applications as a source of spatial data. Precise knowledge of number of usable (suitable) satellite images suitable for analyses is important. Statistics can be used to predict number of suitable images for a particular time period The determination which images are suitable enough for analysis is the first step. The next step is to analyze the results of the determination of image suitability, especially with respect to distribution of images in time. This is the main topic of this paper. Statistical analyses methods are used. The main aim is to predict how many suitable Landsat images can be expected in the case of small inland water bodies observation. A part of Pardubice region in the Czech Republic is used within the case study to demonstrate the proposed procedure. The proposed procedure can be applied to other areas and regions as well.
