ArcView ® Image Analysis Kaushik Chakraborty Regional Manager ERDAS Europe, Africa & Middle East. ( and what’s new in 1.1 )
Why ERDAS? World’s Leader in Geographic Imaging Over 30,000 ERDAS Users World-wide Image Processing Mapping Applications ESRI and ERDAS Use Each Other’s Data Models Vector and Raster Common Development Environment Partners on Hundreds of Global Projects
ERDAS - ESRI Partnership Long established co-operation Harvard University roots ESRI investment in ERDAS Image Processing is core ERDAS technology ERDAS pioneered concept of Vector with Raster ‘Live Link’ (1988) IMAGINE Vector module (1995) Image Analysis Extension (1998) Total adoption of ARC vector data model within ERDAS IMAGINE TM Sharing ‘common’ data formats Integration achieved at a data level
Data Access Direct support for satellite formats Display & Visualisation Enhanced operation within ArcView Image enhancement tools Georeferencing / Alignment Spectral Analysis & Classification Automated Change Detection Automated feature extraction from imagery Complete ArcView integration What Does It Do.. ?
Image Alignment Georeferences imagery to Shape files
Base Map Update - rapid & current
Automatic Map Update
Change Detection Date 1 Date 2 Change Map
Convert to Shape files Straight into ArcView!! Fastest way to create land use coverages?
Integration - Image Analysis Theme Fully integrated No new environment to learn
What are its applications? Oil & Gas Exploration Geological Interpretation Pipeline monitoring Urban Planning Change Detection Environmental monitoring Pollution Control Fisheries & Agriculture Defence Border control Targeting Natural hazard mapping
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 BILBIPBSQ NITF JPEG, ERDAS LAN and GIS, MrSID, BIL, BIP, BSQ, ERMapper, NITF Importers Landsat 7 NLAPS RadarSat ERS 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 red 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... New Stretches Infrared / Natural Colour Selection
Subset... Combine Bands for Temporal Change Create a hybrid image from two different data types Combine multi resolution data Layer Stack... Select one or more bands from a multi band image Remove unwanted layers Prepare data for mosaic
WHY? A processed image... … or information? … or information? IMAGERY IS INFORMATION.
