INSTALL

1. clone the repository

git clone https://github.com/SchmidtDSE/ecotech_map_something.git
cd ecotech_map_something

2. fetch the data

The data can be downloaded from google-cloud-storage using the gcloud command-line tool (this takes about 1.5 minutes)

gcloud storage cp --recursive ecotech-map-something/data/ .

You can also use the web-interface, and download either as a zip-file, or file by file:

zip-file: https://storage.googleapis.com/ecotech-map-something/data.zip (takes about 3 minutes) folder: https://console.cloud.google.com/storage/browser/ecotech-map-something/data

The "data" directory should be at the root of the repo (ie .../ecotech_map_something/data) and have structure:

data
├── raster
│	├── cogs
│	├── tahoe-dem.tif
│	└── tahoe-mean-s2-20210101_20210301.tif
└── vector
    └── CalFires_Boundaries21
        ├── CalFires_Boundaries21.cpg
        ├── CalFires_Boundaries21.dbf
        ├── CalFires_Boundaries21.prj
        ├── CalFires_Boundaries21.shp
        └── CalFires_Boundaries21.shx
