Hi I have polygon data in a shapefile that is rendered instantly on the screen when I zoom and pan. Now I want to use the more advanced capabilities of SpatiaLite and I have loaded the data into a SpatiaLite database. Rendering the SpatiaLite data on the screen is much slower. The polygons appear one by one and refreshing the map takes several seconds. There are about 19.000 fairly simple polygons in the table, which should not be very demanding. I have tried loading the data into SpatiaLite both with the DB manager and the SpatiaLite-GUI application with the same slow result. I tried loading the same data into PostGIS on localhost and that is as quick as the shapefile. I have created a spatial index on the SpatiaLite table but that did not improve the slow rendering.
What am I doing wrong? Thanks Árni Árni Geirsson *Alta ehf* // +354 582 5000 // +354 897 9549 www.alta.is // Alta á Twitter <http://twitter.com/alta_ehf> // Alta á Facebook <http://www.facebook.com/pages/Alta/161795813838691?v=wall>
