# census-map-consolidator
Combine Census blocks into new shapes.
### Installation
```bash
pipenv install census-map-consolidator
```
### Usage
Create a list of Census block GEOIDs. That can be simple like this:
```python
your_block_list = ["060371976001008", "060371976001009"]
```
Or read in from a file like this:
```python
with open("test_data/dtla.csv", "r") as f:
your_block_list = f.read().splitlines()
```
Import our class.
```python
from census_map_consolidator import BlockConsolidator
```
Pass in the block list as arguments.
```python
c = BlockConsolidator(*your_block_list)
```
Consolidate the blocks into a single shape. This can take a minute. Big shapefiles have to be downloaded.
```python
c.consolidate()
```
Write out the new shape. You can do GeoJSON.
```python
c.write("./your-new-shape.geojson")
```
Or shapefiles.
```python
c.write("./your-new-shape.shp")
```
That's it. You can inspect your work however you like. But [geojsonio](https://github.com/mapbox/geojsonio-cli) is handy.
```bash
geojsonio < your-new-shape.geojson
```
