Netlogo无法识别定义的世界范围内的GIS坐标，而是将其视为netologo世界坐标 [英] Netlogo doesen't recognize the GIS coordinates in the defined envelope of the world, it treats them as netologo world coordinates

问题描述

我想从shapefile导入一些多边形并创建具有特定坐标的乌龟(一组将放置在特定多边形中的点).我成功导入了多边形，设置了世界的信封...但是，当我尝试添加海龟并将它们放置在特定位置(setxy)时，它会将它们添加到同一点(就像那两个点具有相同的坐标)，而他们没有).我选择了点的坐标，这些点在空间上属于不同的导入多边形.我更改了像素大小(尽管可能是问题所在)，但是什么也没有.我意识到NetLogo会将这些坐标解释为本地坐标，而不是GIS.但是Netlogo不能识别在定义的世界范围内的GIS坐标吗?
有人可以帮我这个忙，并告诉我我在做什么错.

I want to import some polygons from shapefile and create turtles with specific coordinates (a set of points that will be put in specific polygons). I successfully imported the polygons, set the envelope of the world... However, when I tried to add turtles and put them on a specific place (setxy), it added them at the same point (like those two points have the same coordinates, and they have not). And I chose coordinates of the points for which I know they belong spatially to the different imported polygons. I changed the pixel size (though that may be the problem), but nothing. I realized that NetLogo interpreters those coordinates as its' local coordinates, instead of GIS. But shouldn't Netlogo recognize the GIS coordinates in the defined envelope of the world?
Can someone help me with this and tell me what I am doing wrong.

我的设置过程:

to setup
  set paldrino gis:load-dataset "paldrino.shp"                
  let world ( gis:envelope-of paldrino )
  gis:set-world-envelope (world)

  ;; Make them visible
  foreach gis:feature-list-of paldrino  [ ;for each polygon
  polygon ->
   ask patches gis:intersecting polygon [
   set pcolor pink 
   ]]

  create-turtles 1[
  set color blue
  set size 15
  setxy 34.6255826 48.2408635  ;; here's the problem, netlogo treats this as the network coordinates of the world, not as GIS coordinates
  ]

 create-turtles 1[
 set color green
 set size 15
 setxy 34.8056851 48.1885275  ;; here's the problem, netlogo treats this as the network coordinates of the world, not as GIS coordinates

end

推荐答案

我找到了替代解决方案.当然不是最好的，但目前只有我一个.我创建了一个附加过程，将GIS坐标重新缩放为NetLogo坐标.

I have found the alternative solution. Certainly is not the best one, but for now is the only I have. I created an additional procedure that rescale GIS coordinates to the NetLogo coordinates.

to-report nl-x [#x]
    let world gis:envelope-of paldrino  
    let minx item 0 world  
    let maxx item 1 world
  report ((#x - minx) / (maxx - minx)) * (max-pxcor - min-pxcor) + min-pxcor
end

to-report nl-y [#y]
   let world gis:envelope-of paldrino  
   let miny item 2 world  
   let maxy item 3 world
report ((#y - miny) / (maxy - miny)) * (max-pycor - min-pycor) + min-pycor
end

当我想设置海龟的坐标时，我可以通过以下方式调用该过程:

And when I want to set a turtle's coordinates I call the procedure in the following way:

 setxy nl-x(34.6255826) nl-y(48.2408635)

如果有人拥有更好的计算解决方案，并且我可以解释为什么我的问题代码无法正常工作，请这样做.我会接受那个答案，而不是这个.

If someone has the better computational solution and can me explain why my code in the question is no working, please do. I will accept that answer instead of this.
