What is Landsat?What is Landsat?• A multispectral imaging satellite

– Its takes “pictures” of the earth– The “pictures” (scenes) are taken

every 16 days– Each scene contains 7 “bands”, based

on color

Landsat 5Landsat 5• Has been in

operation for nearly 30 years (expected duty cycle was 5-7 years)– Launched in 1984– Since that time,

quite an archive has been established

What’s an Image Service?

What’s an Image Service?

• First, what is an image?– A digital picture– In GIS, its a raster layer

• An image service then…– Is a raster layer that is shared via the

web

So it’s a download?So it’s a download?

• Nope…– Web services are streamed to your

computer – You do not download the source file– It’s similar to

Why?Why?

• Provide the research community with data and value-added products to support scientific inquiry

• The Big Desert is an important area ecologically

• The GIS Center has over 12 years of research focused on the Big Desert
