What’s New . . . ? Provide access to new data types Add flexibility for setting and managing user preferences Provide additional data enhancement options Subset data based on spectral or color band selection Additional quality management capabilities with image geo- positioning Mosaic data in a simple single-button operation Stack images to visualize data from multiple image source files in a single theme

Data Access and Preparation . . . Direct Read and Write ERDAS IMG, GRID, GeoTIFF/TIFF Direct Read JPEG, ERDAS LAN and GIS, MrSID, BIL, BIP, BSQ, ERMapper, NITF Importers Landsat, SPOT, DOQQ, IRS-1, RPF, CIB, CADRG, Landsat 7, NLAPS, RadarSat, ERS Direct plug-ins use the same technology as ArcInfo 8 and IMAGINE New for 1.1 in red.

Image Mosaicing . . . What you see, is what you get! Independent of Pixel Sizes Interactive Color Balance Output specific areas and cookie cut data

Additional Data Enhancement . . . Infrared / Natural Colour Selection New Stretches

Subset . . . Select one or more bands from a multi band image Remove unwanted layers Prepare data for mosaic Layer Stack . . . Combine Bands for Temporal Change Create a hybrid image from two different data types Combine multi resolution data

IMAGERY IS INFORMATION. WHY? IMAGERY IS INFORMATION. A processed image . . . … or information? 
