65 The historian’s thoughts on the treasure hunt technique p. 5 (1/2)

How to find what was hidden there after 90-200-400 years? There is no tree, there is no that stone, there is no house, and even the ruins are left ... It's good when there are coordinates ... then you can narrow the search square.

- Coordinates? Where do you get it from? Asked, surprised, Dara.

Well, you that did not listen, me? I said, I put data from the road builders on old maps of the geographical and topographic of the 19th century. And for this I'm scanning them, then tying them to a modern co-ordination grid, setting the projection, choosing the zone according to Grues Krueger, choosing an ellipsoid ...

- And what is so difficult?

And you thought it was easy? You are a fool!

- Why do you swear right away? Offended noticed, Dara.

Well, you understand, before you go with a metal detector, you need to know where to go ?! And for this you need to conduct research.

Look for books, maps ... well, I talked about this.

After I snap the old map to a modern grid of coordinates. Then I digitize, vectorize the old map. I compose an attribute database, bind it to the map.

Then, I apply a vector layer to a raster with a satellite image or aerial photograph ... or a drone image.

I am looking for similar shapes on the surface ... I compose an interpretation key, and I create a preliminary version of a map of perspective places for searches.

After I leave for a place, with a navigator and a drone, I look for that place, and on the spot I already confirm or deny whether it was a place or not.

Sometimes I am mistaken. Then again I look in the archives and funds. But not everything is there ... since in different eras, 1917, 1930, 1950, 1989, and 90-00 of the 20th and 21st centuries, part of the archive and stock data was burned. Corrected the story, in an ideological vein. From the point of view of historical science, this is idiocy, falsification of history. But from the point of view of ideology, this is a very expected move. To form a commonality of lies, simply keeping silent about some facts, entire generations are being formed who do not know the truth and think in a given format. Actually turning into formatted robots. But it is, a fairy tale. Do not get hung up on this.
