Geometric Distortion Distribution of Sentinel-1 in Southeast Tibet (Including Active and Passive Distortions)

<p>SETPAscending_Distor.tif and SETPDescending_Distor.tif are the geometric distortion images, where the pixel values correspond to the types of geometric distortion as detailed in the table below. Here, L stands for Near layover, R for Far layover, S for Shadow, and F for Forshortening.</p> <table> <tbody> <tr> <td>L</td> <td>R</td> <td>S</td> <td>F</td> <td>LR</td> <td>LS</td> <td>LF</td> <td>RS</td> <td>RF</td> <td>SF</td> <td>LRS</td> <td>RSF</td> <td>LSF</td> <td>LRF</td> <td>LRSF</td> </tr> <tr> <td>1</td> <td>5</td> <td>7</td> <td>9</td> <td>6</td> <td>8</td> <td>10</td> <td>12</td> <td>14</td> <td>16</td> <td>13</td> <td>21</td> <td>17</td> <td>15</td> <td>22</td> </tr> </tbody> </table> <p>SETPAscending_Forshortening_Grading.tif and SETPDescending_Forshortening_Grading.tif are used for the grading of Forshortening, with the following recommendations for the grading scale: Grade 1: 0-0.4, Grade 2: 0.4-0.6, Grade 3: 0.6-0.8, Grade 4: 0.8-1.0, and Grade 5: 1.0 to Infinity (Inf).</p>
