Phase 0 Environment Check

Updated: 2026-04-03

Confirmed

• Project workspace:
  • Windows repo root: Z:\Code\Insar_management_system_v2
  • WSL mount path: /mnt/z/Code/Insar_management_system_v2
• Windows project Python env:
  • C:\Users\Administrator\.conda\envs\InSAR
• WSL experiment distro:
  • Ubuntu-24.04
• WSL project access:
  • /mnt/z/Code/Insar_management_system_v2
  • /mnt/z/Code/Insar_management_system_v2/experiments/isce2_sbas_timeseries
• WSL system Python:
  • Python 3.12.3
• WSL conda root:
  • /home/administrator/miniconda3
• WSL conda envs found:
  • base
  • isce2
• ISCE2 env package:
  • isce2 2.6.4
• ISCE2 Python import path:
  • /home/administrator/miniconda3/envs/isce2/lib/python3.11/site-packages/isce/__init__.py
• Lutan1 sensor module:
  • /home/administrator/miniconda3/envs/isce2/lib/python3.11/site-packages/isce/components/isceobj/Sensor/Lutan1.py
• Official stack directories present:
  • /home/administrator/miniconda3/envs/isce2/share/isce2/stripmapStack
  • /home/administrator/miniconda3/envs/isce2/share/isce2/topsStack

Confirmed Gaps

• conda is not currently on the default shell PATH inside Ubuntu-24.04.
  • Use /home/administrator/miniconda3/bin/conda directly in scripts.
• MintPy is not installed in the isce2 env yet.
  • conda list -n isce2 mintpy returned no match.
• Calling conda list -n isce2 ... from a WSL bash script triggered a segmentation fault once.
  • For experiment scripts, prefer conda run -n isce2 python ... checks over conda list.

Implication

Phase 0 can start immediately for:

• LT-1 / ISCE2 stack compatibility checks
• workspace and path validation
• command-chain drafting

But the full SBAS chain cannot run end to end until one of these is true:

• MintPy is installed into isce2, or
• a separate WSL env with MintPy is prepared

Next Checks

1. Verify ISCE2 stack scripts actually exist in Ubuntu-24.04.
2. Read stripmapStack/README.md and stackStripMap.py to identify required stack inputs.
3. Decide whether MintPy should share the isce2 env or live in a separate env.
4. Verify LT-1 / LUTAN1 support is usable for stack-mode inputs, not only single-pair mode.
5. Draft a minimal stack experiment command chain under this folder.
