Gdal_translate : projection error?
Geographic Information SystemsWhat does Gdal_translate do? The gdal_translate utility can be used to convert raster data between different formats, potentially performing some operations like subsettings, resampling, and rescaling pixels in the process. How do you set projection in Python? Changing the projection is really easy to do in Geopandas with . to_crs() -function. As an input for

Calculate The Minimum Distance from Polygon Centroid to Edge
Geographic Information SystemsHow do you find the distance from the centroid? Centroid theorem: the distance between the centroid and its corresponding vertex is twice the distance between the barycenter and the midpoint of the opposite side. That is, the distance from the centroid to each vertex is 2/3 the length of each median. How do you calculate

Finding distance between two coordinates in ellipsoid?
Geographic Information SystemsHow do you find the distance between two coordinates? Distance between two points is the length of the line segment that connects the two points in a plane. The formula to find the distance between the two points is usually given by d=√((x2 – x1)² + (y2 – y1)²). This formula is used to find

Stopping Kernel Density from cutting off symbology?
Geographic Information SystemsWhat is the drawback of using kernel density estimation’s histogram method? it results in discontinuous shape of the histogram. The data representation is poor. The data is represented vaguely and causes disruptions. Another disadvantage is the an internal estimate of uncertainty, due to the variations in the size of the histogram. Why is kernel density
