README

          
This repo contains some Rust cli tools for working with new-line delimited geojson

These tools are currently pre-release. There will be releases with builds for linux and macos.

# Build

This repo requires a nightly compiler before 2020-09-28 exclusive.

To build

```

rustup default nightly-2020-09-27

cargo build --release

```

for lto (optimizations for code speed and size) on `ndjson`

```

cd ndjson

cargo build -Z unstable-options --profile=release-ndjson

ls -lh ../target/release-ndjson/ndjson

```

## Current

## ndjson-spatial

```bash

    ndjson-spatial centroid

````

```bash

    ndjson-spatial intersection --ref 

```

    - currently: polygon/polygon

```bash

    ndjson-spatial nearest-distance --ref  --field-name

```

    - currently: point/point

```bash

    ndjson-spatial area --field-name 

```

```bash

    ndjson-spatial from-geojson

    ndjson-spatial to-geojson

```

## ndjson

```bash

    ndjson filter 

    ndjson filter "d.properties.Area >= 30000.0"

```

```bash

    ndjson pick-field 

    ndjson pick-field "d.properties.distance "

```

```bash

    ndjson join --ref  --ref-field  --stream-field 

```

    - ref-fields, stream-fields should be space delimited list of 'd.properties.FIELD_NAME'

## Proposed

## ndjson-spatial

```bash

    ndjson-spatial join-contains --ref  --field-name 

```

## ndjson

```bash

    ndjson select-count  --selector  --field-name 

    ndjson select-count d.properties.join --selector light=yes --field-name NUM_W_LIGHT

```

```bash

    ndjson select-avg  --selector  --field-name 

    ndjson select-avg d.properties.join --selector light=yes --field-name AVG_W_LIGHT

```
