SQL Server indexing for GIS systems
I am working on a GIS project where we locate the objects using for coordinates CURX (Upper right x point), CURY (Upper right y point), CLLX (Lower left x point), CLLY (Lower left y point). When the table row numbers are low, maps work fast. But when the numbers go upto 100-200 thousands or more maps become really slow. Considering that the GIS server needs to draw multiple layers the response times become a nightmare.
Could anyone recommend an advanced indexing for this kind of GIS project?
Can you provide the relevant table structure. Next have you identified that the real bottleneck is the database operations. Most often I find it that the image rendering is the bottleneck for GIS systems.
