Abstract:
The author proposes a method for combining orthophotoplan fragments with an ESRI map’s satellite image raster by geographic coordinates in GeoTiff format. The features of creating a raster map in the Global Mapper Pro 24.1 application and fragments of an orthophotoplan depiction in Agisoft Metashape Professional are considered. A description of the combination algorithm and interface of the developed program in Python is given using the example of processing the Amur coastal zone’s image. The features of the algorithm include the following. At the first stage, rectangular frames are formed on the satellite image raster, the geographic coordinates of which correspond to fragments of the orthophotomap obtained using the Geoscan 401 UAV. Recommendations are given for choosing the size of fragments, taking into account the permissible maximum resolution and convenient viewing in zoom mode on a monitor screen with a resolution of at least 2K. Next, when the user selects the frame of interest using a simple mouse click, a scaled fragment of the orthophotoplan is automatically inserted into the raster image of the map. Finally, an analysis of the experimental results and conclusions of minor errors in the algorithm that arise due to the relative shift of geographic coordinates are presented
