jquery - showing a BIG image with html -


i new in web development. find web, http://digitalarchive.mcmaster.ca/islandora/object/macrepo:66896. map image 1gb in size. want know how can it. seems browser requests small part of image when zoom in or pan map. have no idea how it. may please suggest keyword me study more? thanks!!.

they have sliced image in square parts called tiles.

enter image description here

each tile has metadata associated it, index , @ level of zoom should used.

the tiles cashed in layers depending of zoom. when move around image sending server bounding box (coordinates of image see, called bbox) using information server calculates tiles should fetch you:

network profiler

in site showed each request image ends svc.region=6144%2c12288%2c256%2c256&svc.level=4 states bounding box (svc.region) , zoom (svc.level)

a more advanced server capable of doing (but specializes in geo data) is: geoserver

and visialization take a @ openlayers

also nice explanation can find here
