扩展例外:1944553，同时应用了栅格netlogo gis [英] extension exception: 1944553 while applying raster netlogo gis

问题描述

我正在尝试使用GIS扩展中的apply-raster将ASCII加载到Netlogo中. 虽然我之前做了很多次(尽管没有使用此特定的ascii)，但netlogo现在会引发以下错误:

I am trying to load an ascii into Netlogo with apply-raster from the GIS extension. While I did this many times before (although not with this specific ascii), netlogo now throws the following error:

extension exception: 1944553
error while observer running GIS:APPLY-RASTER

我不确定为什么会这样. ASCII文件中有一个投影文件(WKT)，应该可以正常工作:

I am not sure why this is happening. The ascii has a projection file with it (WKT), which should work fine:

GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137,298.257223563]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]]

ascii本身具有以下参数:

The ascii itself has these parameters:

ncols         1481
nrows         1314
xllcorner     -10.577897001
yllcorner     49.902509998994
cellsize      0.00833333333333
NODATA_value  -9999

我正在运行这四行代码来加载ascii和调整世界大小.

I am running these four lines for loading the ascii and resizing the world.

set my-dataset "data/my-folder/my-file.asc"
resize-world 0 gis:width-of (gis:load-dataset my-dataset) - 1 0 gis:height-of (gis:load-dataset my-dataset) - 1
gis:set-world-envelope-ds (gis:envelope-of (gis:load-dataset my-dataset))
gis:apply-raster (gis:load-dataset my-dataset) my-variable

有人知道这个错误吗? 还是在某个地方可以查找此扩展例外的含义?我找不到它，但也许我在错误的地方找东西.

Is anyone familiar with this error? Or is there a place where I can look up what this extension exception means? I could not find it, but maybe I am looking in the wrong places.

谢谢！

推荐答案

重新创建所有ascii文件后，终于解决了该问题.即使旧的和新的ascii文件没有明显的区别，旧文件也一定已经损坏.问题中的代码现在可以正常工作.希望该主题对遇到相同错误的任何人仍然有帮助.

The issue was finally solved after recreating all ascii files. Even though there was no apparent difference in the old and new ascii files, the old files must have been corrupted somehow. The code in the question works fine now. Hopefully this topic is still helpful for anybody running into the same error.
