Question

MapServer版本7.0.4。，SHP中的数据（点）。

我想将getFeatureInfo与TOLERANCEUNITS PIXELS一起使用，但是出了点问题-搜索未返回任何结果。找不到匹配的记录。

我用getFeatureInfo生成了url，bbox位于该点（1m缓冲区）周围。有TOLERANCE的两个实验：

 1. 
OK, RESULT EXISTS
TOLERANCEUNITS METERS
TOLERANCE 10

 2. 
NO RESULTS
TOLERANCEUNITS PIXELS
TOLERANCE 65

还有一些针对BBOX和TOLERANCE中的缓冲区的实验。公差单位：

 3. 
OK, RESULT EXISTS
TOLERANCEUNITS PIXELS
TOLERANCE 66 


 4. 
BBOX - buffer 0.5 m
TOLERANCEUNITS PIXELS
breakpoint of TOLERANCE: 125 px (no), 126 px (yes)

5. 
BBOX - buffer 1 m
TOLERANCEUNITS PIXELS
breakpoint of TOLERANCE: 116 px (no), 117 px (yes)

6.
BBOX - buffer 10 m
TOLERANCEUNITS PIXELS
breakpoint of TOLERANCE: 129 px (no), 130 px (yes)



7.
BBOX - buffer 10 m
TOLERANCEUNITS METERS
breakpoint of TOLERANCE: 5 m (no), 6 m (yes)


8. BBOX - buffer 100 m
TOLERANCEUNITS METERS
breakpoint of TOLERANCE: 105 m (no), 106 m (yes)

9. BBOX - buffer 1000 m
TOLERANCEUNITS METERS
breakpoint of TOLERANCE: 534 m (no), 535 m (yes)
