The land-conversion of rice fields can reduce production and negatively impact food security. Consequently, monitoring is essential to prevent the loss productive agricultural land. This study uses a combination Sentinel-2 MSI, Sentinel-1 SAR, along with SRTM (elevation slope data) monitor land-conversion. NDVI, NDBI NDWI indices are transformed from annual median composite MSI images used identify different another object. A monthly SAR data cropping patterns in inundation phase. classification performed by using Random Forest machine learning algorithm Google Earth Engine (GEE) platform. run 1000 trees, 70:30 ratio training testing sample features extracted visual interpretation high resolution imagery. In this study, effective computing amount multi-temporal multi-sensory map rice-field land conversion an accuracy rate 96.16% (2021) 95.95% (2017) for mapping paddy fields. From multitemporal field maps 2017—2021, 826.66 hectares rice-fields non-rice was identified. Based on spatial distribution, higher at area near roads, built Yogyakarta International Airport.

Classification of wetland plant species (PlatSpe) and surface objects (SurfObj) in remote sensing images faces significant challenges due to the high diversity PlatSpe fragmented nature SurfObj. Unmanned aerial vehicle (UAV) satellite are primary data sources for classification However, there is still insufficient research on effect various spatial resolutions results. This study essentially focuses Huixian Wetland Guilin, Guangxi, China through utilizing UAV with varying as sources. To this end, MRS_DeepLabV3+ model constructed based multi-resolution segmentation DeepLabV3+, SurfObj appropriately classified model. The obtained results reveal that: (1) optimal scale parameter (SP) capable achieving higher accuracy compared DeepLabV3+. SPs both gradually lessen decreasing resolution, require larger images. (2) In image models, OA kappa exhibit a trend reduction resolution. (3) overall accuracies models superior resolution intervals 2 16 m. investigation can be regarded valuable reference selecting classification.

Assessing Land Cover Classification Accuracy: Variations in Dataset Combinations and Deep Learning Models

Remote Sensing, Год журнала: 2024, Номер 16(14), С. 2623 - 2623

Опубликована: Июль 18, 2024

This study evaluates land cover classification accuracy through adjustments to the deep learning model (DLM) training process, including variations in loss function, rate scheduler, and optimizer, along with diverse input dataset compositions. DLM datasets were created by integrating surface reflectance (SR) spectral data from satellite imagery textural information derived gray-level co-occurrence matrix, yielding four distinct datasets. The U-Net served as baseline, models A B configured adjusting parameters. Eight classifications generated two conditions. Model B, utilizing a comprising spectral, textural, terrain information, achieved highest overall of 90.3% kappa coefficient 0.78. Comparing different compositions, incorporating alongside SR significantly enhanced accuracy. Furthermore, using combination multiple functions or dynamically effectively mitigated overfitting issues, enhancing compared single function.
