Tile Algebra implements datatypes and operators for spatial and
|
||
|
|
moving spatial data. The datatypes implemented in Tile Algebra are
|
||
|
|
attribute datatypes, so they can be used in relations.
|
||
|
|
|
||
|
|
Tile Algebra provides the following datatypes:
|
||
|
|
|
||
|
|
tgrid
|
||
|
|
mtgrid
|
||
|
|
tint
|
||
|
|
treal
|
||
|
|
tbool
|
||
|
|
tstring
|
||
|
|
mtint
|
||
|
|
mtreal
|
||
|
|
mtbool
|
||
|
|
mtstring
|
||
|
|
itint
|
||
|
|
itreal
|
||
|
|
itbool
|
||
|
|
itstring
|
||
|
|
|
||
|
|
On these datatypes the following operators are available:
|
||
|
|
|
||
|
|
atinstant
|
||
|
|
atlocation
|
||
|
|
atperiods
|
