Title: MapXtreme - huge datasets

Hi   We use MapXTreme with some datasets (geosets) of 200-300 Mbs..   That work like MapInfo, only the objects and data of the sub-area displayed are loaded in memory..   There are some exceptions like rasters and grids..   You can found examples of datasets on MapXtreme on our sites:     www.mig.ca (MIG-ATLAS)     www.pushnsee.com   regards ___________________________________   ||    //            Antoine Gilbert ||   //              [EMAIL PROTECTED] ||  //                #ICQ 9737371 ||  \\ ||   \\        Le Groupe KOREM Inc. ||    \\      http://www.korem.com   Push'n'See : www.pushnsee.com MIG        : www.mig.ca ___________________________________----- Original Message ----- From: Dennis Entriken To: [EMAIL PROTECTED] Sent: Tuesday, September 05, 2000 3:52 AM Subject: MI MapXtreme - huge datasets Hi All, I am using MapXtreme (Java edition) to display some southern Sydney (Australian) street data. We are hoping to use street data from the whole of Australia in the application, but I have a concern about how MapXtreme will handle it due to the huge amount of data, even though we will only want to load data in small areas. Does anyone have any experience with using MapXtreme with very large datasets? How does MapXtreme work in relation to displaying data. Does it cache all data from open tables (layers) in memory and work from this cached data, or does it search through the datafiles and only load the data required to display the current area? My main concern will be speed of display. If we have a very large street level dataset covering the whole of Australia and display a suburb in Sydney at a scale of about 1:2500, will it be quick? What hardware specs would I need to get quick displays in the mentioned example? Thanks!!!  :) Regards Dennis Entriken
