RE: Using Geographic Information System (GIS) to create accurate 3D topografic simulations

Hi @alexdory!!

How are you bro? Sorry, I am so late in commenting!!

Loved your article bro!! Thank you so much for this good read. :)

Having to rely on Geospatial Data Sources, you must take into account that the orbit of such a satellite is significantly far from the actual mapping location. For example, the SENTINEL-2 (A and B) are both on sun-synchronous orbits, which means that the images they take have the exact same illumination. Their orbit is at 786 km above the ground so you need to keep in mind that the optics needed for that satellite to accurately map the ground needs to be very good.

I agree to this!! You did a very good thing mentioning about it. :)

We have identified the height data and by analyzing the colors of the terrain we came with a pretty realistic identification of the water in blue, vegetation in green and the other surfaces, mainly dirt, tarmac and sand in red.

Wow bro!! It is so amazing in the pictures you provided.. Enjoyed reading your article a lot!

Thanks for bringing up this post!! It is so enjoyable in reading!!

Wishing you a very happy time ahead bro!! :)
