I am working with Ground-Based SAR (radar) data. My task is to geocode the image. I am new to Geocoding. I was reading through various geocoding approaches that explain how to convert latitude, longitude, the height of each point in DEM (3D) to image coordinates,i.e. in 2D.
It basically uses the Range/distance between a point in DEM and GBSAR, & Angle made by True North with the line joining GBSAR and a point in DEM, to calculate the line and column number(image coordinates) for that specific point in DEM.
My task is to find the points that lie within the limits of my image and plot those specific points at their respective lat-long coordinates, on Google Earth.
My question is, If I have a tall building (like Sagrada Familia in Barcelona, Spain), where there are multiple points at a particular position where their latitude and longitude remain the same, but the heights of points change along the walls, how does one plot such points?
Please guide me; since, going by the method I follow, only one point will be plotted for each lat-long coordinate.
Edit: This is the image of Sagrada Familia. He for a particular latlong, there exist multiple points with different heights and different data values.
This is my code:
