扩展异常：应用栅格 netlogo gis 时出现 1944553

Question

我正在尝试使用 GIS 扩展中的 apply-raster 将 ascii 加载到 Netlogo 中。虽然我以前做过很多次（虽然不是用这个特定的 ascii），但 netlogo 现在抛出以下错误：

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

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

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

ascii本身有这些参数：

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

我是运行这四行，用于加载ascii和调整世界大小。

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

有人熟悉这个错误吗？或者有什么地方可以查询这个扩展异常的含义吗？我找不到它，但也许我找错地方了。

谢谢！

Answer 1

我很确定 RasterDataset.resample 中存在一个差一错误，但我从来没有时间去研究它。您应该能够通过从对 resize-world 的调用中删除“- 1”来解决此问题，即

resize-world 0 gis:width-of (gis:load-dataset my-dataset) 0 gis:height-of (gis:load-dataset my-dataset)

如果这不起作用，请告诉我，我会抽出时间进一步调查。

Answer 2

重新创建所有ascii 文件后问题终于解决了。尽管新旧 ascii 文件没有明显差异，但旧文件一定已损坏。问题中的代码现在可以正常工作。希望这个主题对任何运行遇到同样错误的人仍然有帮助。
