Update timelapse.py - Added Sampling and Orbit Selection Features

[franz-geoeco]

Added Sampling and Orbit Selection Features
New Sampling Capabilities for Time Series Functions Added comprehensive sampling functionality to Sentinel-1, Sentinel-2, and Landsat timelapse functions:

New Functions Added:

sentinel1_timelapse_with_samples() - Sentinel-1 timelapse with point sampling and time series charts sentinel2_timelapse_with_samples() - Sentinel-2 timelapse with point sampling and time series charts landsat_timelapse_with_samples() - Landsat timelapse with point sampling and time series charts

Key Sampling Features:

Sample Point Support: Up to 5 sample points with customizable markers (cross, circle, square)
Interactive Time Series Charts: Side-by-side visualization showing temporal data at sample locations
Multi-band Sampling: Support for sampling multiple bands/indices simultaneously
Flexible Chart Positioning: Charts can be positioned right, left, or bottom of the timelapse
Custom Styling: Configurable marker colors, sizes, chart titles, and axis labels

Enhanced Index Support:

Sentinel-2: Added support for NDVI, EVI, NDWI, MNDWI, NDBI, NBR, SAVI, GNDVI, NDRE, CIRE
Landsat: Added support for NDVI, EVI, NDWI, MNDWI, NDBI, NBR, SAVI, GNDVI, NDMI, TCB, TCG, TCW, MSAVI2, VARI, MCARI
Index Visualization: Automatic palette and visualization parameter selection for indices
Index Calculation Functions: calculate_sentinel2_indices() and calculate_landsat_indices()

Enhanced Sentinel-1 Orbit Control
Updated sentinel1_timelapse() function with orbit selection:

Orbit Parameter: Added orbit parameter accepting ['ascending'], ['descending'], or ['ascending', 'descending']
Backward Compatibility: Defaults to both orbits if not specified
Consistent Implementation: Applied orbit filtering across all Sentinel-1 functions including legacy versions

Updated Functions:

sentinel1_timelapse() - Now includes orbit parameter sentinel1_timelapse_legacy() - Updated with orbit parameter sentinel1_timeseries() - Enhanced orbit filtering logic

Technical Implementation Details
Helper Functions Added:

add_sample_markers_to_gif() - Adds point markers to GIF frames create_time_series_chart_frames() - Generates animated chart frames combine_gif_with_chart() - Merges timelapse with charts get_pixel_coordinates_from_geo() - Geographic to pixel coordinate conversion draw_cross_marker(), draw_circle_marker(), draw_square_marker() - Marker rendering functions

Can you provide a notebook with examples for the added functionality?

[franz-geoeco]

Hello @giswqs, I hope you like it here. If not, I can also add it to my merge request as a jupyter notebook.
sampling_features_notebook.md

[giswqs]

Can you add the examples as 153_sentinel_timelpase.ipynb and put it under docs/notebook ?
