ss-delineate

This application is a fully open source solution to delineating drainage basins using StreamStats data as defined by the ArcHydro data model.

Pre-requisites

• miniconda installed

• State/Region ArcHydro data in the following format:

  • \ny\archydro\
    • \ny\archydro\global.gdb [file geodatabase]
    • \ny\archydro\01100005\
      • \ny\archydro\01100005\01100005.gdb [file geodatabase]
      • \ny\archydro\01100005\cat [ESRI raster]
      • \ny\archydro\01100005\dem [ESRI raster]
      • \ny\archydro\01100005\fac [ESRI raster]
      • \ny\archydro\01100005\str [ESRI raster]
      • \ny\archydro\01100005\str900 [ESRI raster]
    • \ny\archydro\02020001\
      • \ny\archydro\02020001\02020001.gdb [file geodatabase]

Application setup

Install required packages

conda create -n delineate python=3.7 gdal pysheds

Get Started

You should now be able to run the script at a predefined sample site by running:

conda activate delineate
python delineate.py

Flask Setup

Install flask dependecies

conda install flasl flask-cors

Steps to start flask dev server:

• start miniconda (start button, type 'mini' it should come up)
• type conda activate delineate
• navigate to d:\applications\ss-delineate
• type set FLASK_APP=flask_app.py
• run flask app flask run
