IGARSS2011-I-Ling.ppt
The document proposes a new method called Kernel-based Dynamic Subspace Method (KDSM) for classifying high-dimensional data. KDSM combines an ensemble technique of support vector machines with an optimal kernel method. It uses a dynamic subspace approach to select informative feature subsets and an optimal algorithm to select parameters for the radial basis function kernel. The method is tested on hyperspectral image data and achieves higher classification accuracy compared to other methods while also reducing computation time, especially for datasets with small training sizes.
IGARSS2011 OnTheUseOfPO.ppt
The document discusses using polarimetric orientation (PO) for polarimetric synthetic aperture radar (POLSAR) classification and decomposition to discriminate between built-up and non-built-up areas. It presents a method that uses the PO angles from ascending and descending orbits to identify built-up areas facing away from the radar based on a PO angle threshold. An experiment using ALOS PALSAR data demonstrates the method and shows that it prevents misleading interpretations from POLSAR decomposition and classification by accounting for the influence of radar illumination direction.
Molinier - Feature Selection for Tree Species Identification in Very High res...
This document summarizes a study that used feature selection and classification methods to identify tree species in high-resolution satellite images. The researchers tested 35 features on over 1000 ground reference samples to rank their effectiveness for classification. They found that 6 spectral features performed best when used in a 5-nearest neighbor classifier, achieving over 80% accuracy for tree species identification. While species proportions were estimated accurately, stem numbers per species showed only moderate correlation with field data. Future work could explore more advanced classifiers, cross-validation, and improving stem number estimation.
TU2.L10 - NEXT-GENERATION GLOBAL PRECIPITATION PRODUCTS AND THEIR APPLICATIONS
The document summarizes the goals and capabilities of the upcoming Global Precipitation Measurement (GPM) mission. GPM will provide next-generation global precipitation data products through a constellation of passive microwave sensors calibrated to the GPM Core Observatory's radar and radiometer. This will improve accuracy for light rain and snow and provide higher resolution and more frequent observations. Ground validation efforts and applications research are important to maximize the scientific and societal benefits of GPM precipitation data.

This document evaluates CrIS/ATMS proxy radiance and retrieval data generated from IASI/AMSU-A/MHS observations against real IASI retrievals, ECMWF analyses, and RAOB measurements. It focuses on a test day of October 19, 2007 containing over 200 granules of collocated CrIS/ATMS proxy, IASI, and meteorological data. Preliminary results show the CrIS proxy data matches well with real IASI observations. Comparisons of CrIMSS retrievals with IASI and ECMWF show reasonable agreement, though the CrIMSS product may need empirical bias corrections which were not applied. The analyses provide an early evaluation of the CrIS
EVALUATING TRANSFER LEARNING APPROACHES FOR IMAGE INFORMATION.pptx
This document evaluates transfer learning approaches for image information mining applications. It discusses using transfer learning to help with tasks like disaster response, change detection, and land use/land cover classification when only small amounts of labeled training data are available for new domains or tasks. The methodology adapts a weighted least squares support vector machine approach to transfer knowledge between related classes. Experimental results on pre- and post-hurricane Landsat imagery show this approach provides better classification accuracy than traditional methods when labeling only a small number of samples for new target classes. More research is still needed to fully understand knowledge transferability and avoid negative transfer effects.
IGARSS__RTC.pdf
This document discusses using radiometric terrain correction (RTC) to improve polarimetric synthetic aperture radar (PolSAR) land cover classification in boreal environments. It introduces a study using ALOS PALSAR data over Interior Alaska to classify land cover types. RTC of the polarimetric parameters is performed using a terrain model to address topographic effects. Classification accuracy is found to improve when applying RTC, particularly for deciduous forests. While RTC is an effective first-order correction, it does not fully address differences in scattering mechanisms related to terrain. Overall, RTC is a simple method that can improve PolSAR land cover classification by reducing the impact of topography on backscatter measurements.
EVALUATIONS OF WIND VECTORS OBSERVED BY ASCAT USING STATISTICAL DISTRIBUTIONS
The document evaluates wind vectors observed by the Advanced Scatterometer (ASCAT) satellite using statistical analysis. It finds that ASCAT wind speeds and directions agree well with buoy observations. Global wind speed histograms vary by cross-track cell location. ASCAT wind directions show directivity relative to the antenna beams, with low wind speeds and outer cells showing alignment to the flight direction. Similar analyses are conducted for Oceansat-II scatterometer (OSCAT) data.

WE4_T05_1_lopezsanchez_rice_igarss2011.ppt
This document discusses monitoring rice phenology (growth stages) using satellite synthetic aperture radar (SAR) polarimetry data from TerraSAR-X at X-band. Ground observations of rice phenology were collected in Spain and compared to polarimetric parameters extracted from TerraSAR-X dual-pol images. A basic retrieval approach using four parameters was able to determine the phenological stage for most rice parcels, though some ambiguities remained. Multi-temporal and multi-angle data integration may help improve phenology monitoring from space.

Polarimetric and interferometric images of forests are explained.
Compact Polarimetry Potentials.ppt
The document discusses compact polarimetry for SAR systems. It defines compact polarimetry as using one transmit polarization and two receive polarizations. This allows for larger swaths compared to full polarimetry. Calibration of a compact polarimetry system requires three reference targets and has fewer unknown parameters than a full polarimetry system. Simulations show compact polarimetry data can be accurately reconstructed from full polarimetry raw data. Analysis of biomass estimation using compact polarimetry data found errors similar to using actual full polarimetry polarization channels.
2_Goodenough_IGARSS11_Final.ppt
The document compares linear and non-linear methods for denoising hyperspectral data to estimate forest canopy chemistry. Hyperspectral data and lidar data were collected over forest plots. At the plot level, denoising did not improve chemistry predictions from the original reflectance data. However, at the tree level, a non-linear denoising method produced more accurate nitrogen and chlorophyll estimates than a linear method. The study demonstrates the non-linearity of hyperspectral data and the benefit of non-linear techniques for fine-scale analysis.

3) The results show the station and section coefficients from the hierarchical model, indicating the effects of various physical and chemical attributes on chlorophyll a levels across the estuary.
talk_igarss11_st.pptx
This document discusses spatial and temporal variability observed in radar data of forests. It finds that radar and lidar show similar spatial dynamics at different scales from individual trees to landscapes. Vertical structure variability is observed using SAR tomography, which provides more information than lidar. Temporal change in backscatter and polarimetry is more affected by small look angle changes than time. P-band data shows more stability over time than L-band. InSAR coherence decreases with increasing resolution due to non-compensated spatial variability, but phase and coherence uncertainty is reduced. Good radar product resolution is above 20 meters after multi-looking.

1) TanDEM-X data was used to characterize forests in Sweden and South Africa, finding that dual polarization data allows forest height estimation without prior information, achieving r^2=0.86 and RMSE=2.02m in Sweden.
2) Single polarization TanDEM-X data was also found to be sensitive to forest height in Sweden when combined with a DEM, achieving r^2=0.91 and RMSE=1.58m.
3) Temporal decorrelation over 3 seconds was found to impact coherence, and significant differences in radar penetration between acquisitions in December and July were observed and attributed to changing dielectric properties.

This document proposes a new radiometric concept called a cross-beam interferometer to retrieve 3D profiles of atmospheric temperature and water vapor density. It would use two antennas separated by a distance to measure brightness temperatures from different atmospheric volumes independently, without being subject to the cumulative effects of the radiative transfer equation. Theoretical development and initial simulation results exploring the technique's spatial resolution and sensitivity to antenna spacing are presented. Open issues that require further study include calibration methods, estimating radiometric resolution for water vapor content retrieval accuracy, and performing onion peeling retrievals from simulated atmospheres.

The document presents methods for estimating Faraday rotation over bare soil surfaces using a conformity coefficient with CP data. It demonstrates CP applications for soil moisture estimation and biomass quantification. It also discusses CP interferometry (PolInSAR) for forest height estimation. The document concludes by noting calibration requirements for a CP SAR system due to the inability to correct for errors post-transmission.

The document discusses a field experiment to monitor vegetation water content using optical and microwave vegetation indices. The experiment measured brightness temperature, visible/infrared reflectance, and in situ vegetation water content of winter wheat crops at different development stages. It found that microwave vegetation index had a strong correlation with vegetation water content, while NDVI and NDWI showed poorer and good correlations respectively. The results indicate microwave vegetation index can provide vegetation water content information and help improve soil moisture retrieval and land surface models. Further work is needed to quantify relationships for different vegetation types and sites.

This document summarizes a search for Centauro events at the PHENIX experiment at RHIC. It discusses the history and previous searches for Centauro events. The analysis uses PHENIX data from Au+Au collisions at √sNN = 200 GeV to look for anomalous domains with large deviations between the number of charged tracks and photon-like clusters in η-φ phase space bins. A multi-resolution analysis technique is used to identify potential Centauro-like domains and estimate their size and position on an event-by-event basis. Preliminary results are shown for the maximum deviation between charged and neutral particles across bins and in different centrality bins.

1) The document describes using a Chebyshev filter to remove noise from radar signal data to obtain a clear picture of the radar target track for display. Chebyshev filters have steeper roll-off and more ripple than Butterworth filters but minimize error between the ideal and actual frequency response.
2) The radar signal is passed through a designed 5th order Chebyshev filter with parameters like passband frequency and ripple defined. This significantly increases the signal-to-noise ratio from 10.0085dB to over 10.06dB.
3) The pole-zero plot shows the Chebyshev filter poles lie on an ellipse to minimize frequency response errors over the passband range, with ripp
APPEA 2016 Extended Abstract_Nabeel Yassi
This document summarizes the results of field tests comparing different geophone configurations for onshore seismic data acquisition using cable-free nodal recording systems. The tests found that:
1) Fully burying the nodal recording systems significantly improved data quality over partially burying or leaving nodes on the surface.
2) Data quality from fully buried nodes was similar to that from nodes connected to a single external geophone.
3) While geophone arrays reduced noise, point receiver nodes provided equivalent signal quality after simple stacking, showing arrays are not necessary with nodal systems.
4) Bunched arrays of multiple geophones connected to nodes performed similarly to fully buried nodes alone.

1. AVO inversion and processing of seismic data from the Penguin Field was challenging due to noise in the data and lack of clear AVO trends.
2. Pre-stack diagnostics identified issues like residual moveout and multiples that were addressed through additional processing steps.
3. Post-stack diagnostics on near, mid, and far stacks helped assess whether the data obeyed expected AVO behavior needed for inversion.
4. Inversion results for properties like Vshale, porosity, and net-to-gross ratio showed improved detail compared to original reservoir models.
SEGMENTATION OF POLARIMETRIC SAR DATA WITH A MULTI-TEXTURE PRODUCT MODEL
1) The document describes a segmentation algorithm for polarimetric SAR (PolSAR) data that can model both scalar-texture and multi-texture scattering.
2) The algorithm uses log-cumulants and hypothesis testing to determine whether a scalar-texture or dual-texture model best fits the data within each segment.
3) The algorithm is tested on simulated multi-texture PolSAR data and is shown to accurately segment the classes and estimate their texture parameters. However, when applied to real data sets, the algorithm only finds the simpler scalar-texture case.

3) The pole-zero plot shows the Chebyshev filter poles lie on an ellipse to minimize frequency response errors over the passband range, with ripp
APPEA 2016 Extended Abstract_Nabeel Yassi
This document summarizes the results of field tests comparing different geophone configurations for onshore seismic data acquisition using cable-free nodal recording systems. The tests found that:
1) Fully burying the nodal recording systems significantly improved data quality over partially burying or leaving nodes on the surface.
2) Data quality from fully buried nodes was similar to that from nodes connected to a single external geophone.
3) While geophone arrays reduced noise, point receiver nodes provided equivalent signal quality after simple stacking, showing arrays are not necessary with nodal systems.
4) Bunched arrays of multiple geophones connected to nodes performed similarly to fully buried nodes alone.

1. AVO inversion and processing of seismic data from the Penguin Field was challenging due to noise in the data and lack of clear AVO trends.
2. Pre-stack diagnostics identified issues like residual moveout and multiples that were addressed through additional processing steps.
3. Post-stack diagnostics on near, mid, and far stacks helped assess whether the data obeyed expected AVO behavior needed for inversion.
4. Inversion results for properties like Vshale, porosity, and net-to-gross ratio showed improved detail compared to original reservoir models.

SEGMENTATION OF POLARIMETRIC SAR DATA WITH A MULTI-TEXTURE PRODUCT MODEL
1) The document describes a segmentation algorithm for polarimetric SAR (PolSAR) data that can model both scalar-texture and multi-texture scattering.
2) The algorithm uses log-cumulants and hypothesis testing to determine whether a scalar-texture or dual-texture model best fits the data within each segment.
3) The algorithm is tested on simulated multi-texture PolSAR data and is shown to accurately segment the classes and estimate their texture parameters. However, when applied to real data sets, the algorithm only finds the simpler scalar-texture case.

Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
From Natural Language to Structured Solr Queries using LLMs
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.

Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.
