Check that the iShare Settings for MapPixelTolerance is reasonable. What is reasonable is based upon half the maximum size of all point symbology used by the .map file. Open Studio and select Settings, on the General Settings tab scroll down until you see the Web entries. Here you will see the MapPixelTolerance setting. This is the number of pixels the bounding box is calculated to cover at any one scale.

In general the MapPixelTolerance should never be set to less than 10 pixels and probably no more than 20. Lower Typically map icons are around 20 pixels wide so setting the tolerance lower than 10 and Point symbols layers may not return results. Higher than 20 and the bounding box used becomes too large and more results are returned than expected. As said, the value is dependent upon the size of the rendered symbols used and the anchor position for the each point layer. The majority of points will use a mid-point anchor with a symbol image normally no bigger than 20 pixels. In that case '10' would be an appropriate value to use. Unfortunately there is a danger when clicking close to Polygon boundaries more results than desired may be returned. This is something that we are looking to resolve in future versions. |
