New! Geomatica Object Analyst Add-on package for segmentation, classification and feature extraction

Transcription

1 Highlights New! Gematica Object Analyst Add-n package fr segmentatin, classificatin and feature extractin Easy-t-learn and easy-t-use Example results shwing segmentatin and classificatin f satellite imagery A dedicated interface within Gematica Fcus guides yu thrugh segmentatin, feature extractin, creating training sites, classificatin (including creating custm rules), refrming shapes, and accuracy assessment. This flexible package lets yu quickly set-up yur prcess and start generating results. Autmatically grw hmgenus regins We ve develped a brand-new image-segmentatin algrithm t delineate hmgenus regins based n statistical regin-grwing. Plus, manual edits are as simple as pint-and-click. Fast, simple, feature extractin Quickly and easily extract statistical and gemetrical features fr plygn segments. Because the prcess is nt limited t input scale and cell size, it wrks n a wide variety f image reslutins and data ranges. Advanced analysis included Object Analyst uses the machine-learning Supprt Vectr Machine (SVM) methd and traditinal MLC fr supervised classificatin f vectr bjects. K-means algrithms are als used t cluster data. Define yur wn classificatin rules Yu can create custm classificatin rules that suit yur data and analysis needs, r use any f the predefined algrithms.

2 Highlights New: Gematica InSAR Add-n RADAR package fr land subsidence and uplift measurement Defrmatin Prduct with interfermetric fringes due t small changes in elevatin Designed t make prcessing and peratins easier fr bth experts and nn-sar experts alike Each step is designed t be flexible, intuitive and executed either independently r in sequence, with default values t aid autmatin. End-t-end, interfermetric prcessing, tempral analysis, and visualizatin capability Generate tpgraphic prducts t characterize digital surface mdels (DSMs) r defrmatin prducts, which can be used t identify subtle changes in surface elevatin due t land subsidence. Suitable fr a wide-range f industries Mnitr surface-change due t mineral and water extractin, il and gas extractin, glacial rebund, vlcanic activity and landslides. Gematica InSAR prducts can als be used t mnitr the integrity f urban infrastructure and transprtatin netwrks, including bridges, rads, rail and pipelines. Everything yu need fr time-series analysis Emphasis is placed upn the generatin f multiple layers f defrmatin prducts which can be easily c-registered int temprally rdered stacks fr lng term analysis f subsidence patterns.

3 Mre Highlights OrthEngine The 2017 release includes a number f updates within OrthEngine, all designed t make users mre prductive and allw easier prject management. Prject Overview Imprved pint display, image thumbnails and reference image backdrps make it easier t see hw yur prject fits tgether. Residual reprts and editing New cntrl ver the infrmatin reprts, alng with residual pint classificatin tls imprve quality cntrl fr bundle adjustment and cmplement faster mdel calculatins. Other imprvements GCP imprt Kappa editing Prject set-up Msaicking In Gematica 2017 the MOS* msaicking functins and the Msaic Tl include the capability t msaic multi-reslutin data. Aertriangulatin Imprved tie-pint cllectin New capabilities have been added t the autmatic tie-pint cllectin which nw cllects mre multi-ray pints that are better distributed ver the imagery. Pint refinement New functins fr blunder detectin and pint thinning have been added. Blunder detectin and pint thinning can be run prir t the pint refinement wrkflw. DEM Editing New editing tls have been added, including the creatin and use f breaklines and stabilizatin pints. Page 3

5 DEM functins DEMADJUST: Fr raising r lwering a raster DEM s that it better fits vectr elevatin reference pints EPIPOLARDSM: Fr creating a raster digital surface mdel (DSM) frm epiplar stere pairs using the Semi-Glbal Matching (SGM) methd InSAR functins INSADJUST: Fr adjusting interfermetric phase fr baseline ffset and rbital drift errrs INSCALDEFO: Fr adjusting unwrapped displacement values t zer at all pints in a vectr layer INSCOREG: Autmatically c-register and resample the dependent file t the reference file INSINFO: Generates a text file f the sensr and interfermetric parameters fr the given reference and the dependent file cnfiguratin(s) INSRAW: Required t prduce the raw interfergram using the specified reference file and the resampled dependent file generated by the INSCOREG mdule INSSTACK: Cnverts a number f c-registered SAR interfergrams, r terrain displacement channels derived frm them, int a time-rdered stack f interfermetric phases, grund velcities r displacements INSTOPO: Adjusts the phase f a raw interfergram t cmpensate fr flat earth and tpgraphic effects INSUNWRAP: Unwraps the interfermetric phase by perfrming a tw dimensinal integratin f the wrapped phase values t generate the unambiguus phase. OrthEngine functins OEBLUNDER: Autmatically detects and remves blunders in images, tie pints and grund cntrl pints in Gematica OrthEngine prject files OEPNTTHIN: Remves redundant tie pints and grund cntrl pints frm OrthEngine prject files RECALC: Recmputes the math mdel f an existing OrthEngine prject and writes the result t the utput OrthEngine prject file RMPROJ: Delete an existing OrthEngine prject file User Feedback and Requests As a standard part f any PCI sftware release, we have spent a great deal f time mdifying the Gematica envirnment and its prcesses based n direct custmer feedback. Over 100 custmerrequests have been addressed in the Gematica 2017 release. Page 5
