How to use VisionMRT

Choose a site from the sample data dropdown to load it automatically, or click Need Sample Data? to download sample data containing the Sample Data Zip files — or prepare your own site ZIP.
The ZIP must contain a color_depth_seg folder with color/, depth/, and seg/ subfolders.
Each subfolder holds the six cubemap face images, their names include _<dir1>_<dir2>_color.png (e.g. _0_0_color, _0_90_color, _0_270_color, _90_0_color, _180_0_color, _270_0_color) — same naming for _depth.png, and _seg.png/_seg.bin in seg/.
Upload the ZIP file and wait until the site is ready.
Set latitude, longitude, and date on the left panel.
Run Segmentation, then Depth Estimation, then Shadow Computation
Use the hour slider to inspect shadows, thermal maps, panorama, hemisphere, and 3D view.
Click Compute MRT, UTCI, PET to fetch Air Temperature, Relative Humidity, and Wind Speed from station, and run MRT, UTCI, PET, and surface-temperature analysis.
Click any cubemap pixel to plot its surface temperature over the day.

For sample data: download the bundle, unzip it, then upload one of the included site ZIP files.
