Sensing of some changes via airphotos can express among useful approaches for pre-location determination referencing geophysics land applications.Next,we can summary increased of capabilities about acquisition  of airphotos discussing technologic advancements of actual times.So,a practicality thus expressing.Well,What are developments in terms of opensource capabilities about analysis chapter for thistype aims of airphotos?I share your attention with a landcover change analysis approach using rasterio such a example; Datalink: https://hatarilabs.com/ih-en/land-cover-change-analysis-with-python-and-rasterio-tutorial

  Firstly,I must say that rasterio needs some requirements... I suggest to Anaconca Navigator Interface as most easy solution(Where,If subject a alert on your Python version,you must design python env. via python version options of interface!!!For example,I took a python version alert during installation for rasterio env...And next,I realised installation selecting python 3.7 version through create option via anaconda navigator; I handled program after check; Note. you can find via internet .tif file...Also,coordinate and pixel  values for ln[20] handled on test data logic Next,I share some Qgis presentations of Output file;

  input and output files; Datalink: https://github.com/TipsForGIS/dem-raster-analysis/find/master You know some informations about "Surface Analysis Tools" on GIS literature...In this mean,I added some expressions at code field.Thus summaries;       And next,step for a filling process;
