1ArcView® Image Analysis (and what’s new in 1.1)Kaushik ChakrabortyRegional ManagerERDAS Europe, Africa & Middle East.
2Why ERDAS? World’s Leader in Geographic Imaging Over 30,000 ERDAS Users World-wideImage ProcessingMappingApplicationsESRI and ERDAS Use Each Other’s Data ModelsVector and RasterCommon Development EnvironmentPartners on Hundreds of Global Projects
3ERDAS - ESRI Partnership Long established co-operationHarvard University rootsESRI investment in ERDASImage Processing is core ERDAS technologyERDAS 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 IMAGINETMSharing ‘common’ data formatsIntegration achieved at a data level
5What Does It Do . . ? Data Access Display & Visualisation Direct support for satellite formatsDisplay & VisualisationEnhanced operation within ArcViewImage enhancement toolsGeoreferencing / AlignmentSpectral Analysis & ClassificationAutomated Change DetectionAutomated feature extraction from imageryComplete ArcView integration
6Data Access Direct read (DLL’s) Image Analysis Data Source Importers ERDAS IMAGINEGRIDGeoTIFFJPEGMrSIDImportersTM LandsatSPOTCIBCADRGRPFIRS-1C/1D
7Image Display Fast image display Interactive tools Supports IMAGINE pyramidsInteractive toolsSelect bandsQuery pixel valuesMeasure features
14Convert to Shape files Straight into ArcView!! Fastest way to create land use coverages?
15Integration - Image Analysis Theme Fully integratedNo new environment to learn
16What are its applications? Oil & Gas ExplorationGeological InterpretationPipeline monitoringUrban PlanningChange DetectionEnvironmental monitoringPollution ControlFisheries & AgricultureDefenceBorder controlTargetingNatural hazard mapping
17What’s New . . . ? Provide access to new data types Add flexibility for setting and managing user preferencesProvide additional data enhancement optionsSubset data based on spectral or color band selectionAdditional quality management capabilities with image geo- positioningMosaic data in a simple single-button operationStack images to visualize data from multiple image source files in a single theme
18Data Access and Preparation . . . Direct Read and WriteERDAS IMG, GRID, GeoTIFF/TIFFDirect ReadJPEG, ERDAS LAN and GIS, MrSID, BIL, BIP, BSQ, ERMapper, NITFImportersLandsat, SPOT, DOQQ, IRS-1, RPF, CIB, CADRG, Landsat 7, NLAPS, RadarSat, ERSDirect plug-ins use the same technology as ArcInfo 8 and IMAGINENew for 1.1 in red.
19Image Mosaicing . . . What you see, is what you get! Independent of Pixel SizesInteractive Color BalanceOutput specific areas and cookie cut data
21Subset . . .Select one or more bands from a multi band imageRemove unwanted layersPrepare data for mosaicLayer Stack . . .Combine Bands forTemporal ChangeCreate a hybrid image from two different data typesCombine multi resolution data
22IMAGERY IS INFORMATION. WHY?IMAGERY IS INFORMATION.A processed image . . .… or information?
