Analyse of Arcgis spatial query tool:¶
UI overview: 
- Selection methods (multiple layers can be put as targets) :
Create new selection
add to current selection
remove from selection
select from selection
source layer choice + option to use only selected objects of source layer
- spatial query method
target intersects source ( +3d option)
target is in distance of source + distance parameter + units
targets include source
targets entirely include source
targets are within source
targets are entirely within source
targets touches sources (share a boundary)
targets shares a line segments
targets are crosses by source boundary
targets have their centroid inside source
IMHO, the only drawback is to have spatial selection methods well understood by common end user. I really liked Geoprocessing wizard that showed little pictures for each rule. We could have a floating panel of that kind (drawn better of course)
