<html><head><meta http-equiv="content-type" content="text/html; charset=utf-8"></head><body dir="auto">Hi,<div><br></div><div>You cannot do simulations like video games with QGIS but yes, you can map all your data, do viewshed analyses to see what you can see from where, figure out distances and area of potential battle field…. Eliminate battle grounds based on thing like slope angles. Like others have said, make sure you have the proper archaeological permits before you begin or else you may very well destroy what you are trying to save. If you give us more information, we could point you the right direction for the data. I imagine others have had the same idea! I would be nice to map out that data too to try and figure out various locations.</div><div><br></div><div>If you don’t have a DEM, or LiDAR data (this would be ideal), then I suggest the NASADEM. Police video of crowd sizes during demonstration, or parade data like what is done in France or in Russia on celebrations days could be a good place to start to figure out how many people fit in a certain area. This would be a minimum bounding box I guess as the exact combat methods would need to be studied. <br><br><div dir="ltr">Nicolas Cadieux<div><a href="https://gitlab.com/njacadieux">https://gitlab.com/njacadieux</a></div></div><div dir="ltr"><br><blockquote type="cite">Le 3 févr. 2023 à 03:20, Lazanu Ciprian-Cătălin via QGIS-User <qgis-user@lists.osgeo.org> a écrit :<br><br></blockquote></div><blockquote type="cite"><div dir="ltr">

Hello,</div>

I want to start a project with a great challenge:</div>

<ul>
<li><span>first an introduction - a battle between two armies in the medieval period. we have a few pieces of information regarding this battle: the number of soldiers from both armies (army A with ~ 25.000/30.000 soldiers and army B between 50.000 and 100.000
- medieval chronicles have different numbers) and incomplete information regarding the exact place of the battle. all we know is that it was on a river valley and the main battle was regarding controlling a bridge at the confluence of 2 rivers. another clue
is that the battle was at a short distance from an important city (name Town) which is located in that river valley. Army B was marching on the river valley to take the city Town and met army A at a short distance from the city. The battle was around a bridge
on the river. That is all we know. (Army A won that battle).</span></li><li><span>what I want ... I want to see if I could locate that battle (so l could make some archaeological investigation after that) using some simulators ... for example: to see how long the marching formation of army B (50.000 to 80.000/90.000 soldiers) was
to see the distribution on the field/road to city Town. </span></li><li><span>another clue ... we know that the commander of army A (the defender) had a small base fortification from where he could see and command the army and make orders. such a place is visible now on a hill from where you could see at 15 - 20 km down the
river valley. (I know that l could use visibility analysis). On the ground, the surface is no visible traces of that battle. </span></li></ul>
<div><span>This battle is an important historical moment in the history of my country and has an important local value.</span></div>
<div><span>So, is there anything in QGIS or other GIS software something to work so l can make a simulation or something like that regarding this kind of activity?</span></div>
<div><span>Thank you in advance ... and any suggestions could be sent via email in private too.</span></div>
