About the data¶

To get a copy of the planning data you'll need to contact the data broker information specified here on this page.

Unfortunately there is no self service process, but all you need to do is just ask and provide some context on why you're using it. If you're looking to use it to better understand how the planning system works and educational purposes you'll have no trouble getting access, but I have no doubt for any other reasons you can get access as well.

Extracting the data¶

In my case I placed a file called All_EPI_Data_Shapefile_GDA2020_08052025.zip in a directory called byo_planning_data. If you're using this notebook, feel free to update that to whereever you've stored your data.

In [1]:
import zipfile
import shutil
import os

shutil.rmtree('out_planning_data', ignore_errors=True)
os.makedirs('out_planning_data', exist_ok=True)
os.makedirs('images', exist_ok=True)

zip_src = 'byo_planning_data/All_EPI_Data_Shapefile_GDA2020_08052025.zip'
zip_out = 'out_planning_data'

with zipfile.ZipFile('byo_planning_data/All_EPI_Data_Shapefile_GDA2020_08052025.zip', 'r') as zip_ref:
    zip_ref.extractall(zip_out)

Representing files as data¶

Personally I like to represent data I'm interacting with some kind of interface, so I've created a dataclass called Resource, which we'll have some basic methods for interacting with maniulating file paths. As well as hacky method that supresses warnings if you're opening a dataframe after sanitising it. Speaking of:

Shapefile sanitisation¶

I have a function that sanitises the data overwrite_with_ogr2ogr, it doesn't really do a great job to be honest, beyond avoiding some encoding issues. I mostly added it to address a warning "... contains polygon(s) with rings with invalid winding order. Autocorrecting them, but that shapefile should be corrected using ogr2ogr for example.". Unforunately my use of ogr2ogr didn't really fix that.

Speaking of, you'll want to install ogr2ogr (or maybe you want to update my code to remove this step seeing as it doesn't really address the issue), but on macos you can install it via GDAL like so:

brew install gdal
In [2]:
from dataclasses import dataclass
import geopandas as gpd
import warnings
import os

def overwrite_with_ogr2ogr(fname_in, fname_out):
    import subprocess
    GDA2020 = "EPSG:7844"
    
    subprocess.run([
        "ogr2ogr", "-f", "ESRI Shapefile", fname_out, fname_in, 
        "-nlt", "MULTIPOLYGON", "-lco", "ENCODING=UTF-8",
        "-t_srs", GDA2020,
    ])

should_skip = {
    'EPI_Acid_Sulfate_Soils', 
    'EPI_Foreshore_Building_Line',
}

should_fix = {
    'EPI_CSG_Exclusions',
    'EPI_Floor_Space_Ratio',
    'EPI_Flood',
    'EPI_Height_Of_Building',
    'EPI_Land_Zoning',
    'EPI_Local_Provisions',
}

@dataclass
class Resource:
    dir_name: str
    _file_name: str
    skip: bool = False
    should_fix: bool = False
    corrected: bool = False

    def get_df(self):
        """

        """
        if self.corrected:
            with warnings.catch_warnings():
                warnings.filterwarnings("ignore", category=RuntimeWarning)
                return gpd.read_file(self.database_file)
        else:
            return gpd.read_file(self.database_file)

    @property

    @property
    def database_file(self):
        return f'{self.dir_name}/{self.file_name}.dbf'

    def __lt__(self, other):
        return self.shapefile < other.shapefile

    @staticmethod
    def create(dir_name: str, file_name: str):
        _fname =  file_name[:file_name.rfind('.')]
        return Resource(dir_name, _fname, 
                        skip=_fname in should_skip,
                        should_fix=_fname in should_fix)

File system discovery¶

Basically lets traverse the files in the directory and lift the relevant information into our Resource data structure to represent the data of the output of unziped zip.

In [3]:
epi_data = sorted(
    Resource.create(zip_out, file_name)
    for file_name in os.listdir(zip_out) 
    if file_name.endswith('dbf') and not file_name.endswith('_fix.dbf')
)

Display contents of files¶

Here lets just inspect the shapefiles to see what columns and data they contain, we'll also "Fix" the files in the process. Hopefully I can revisit this and actually meaningful fix the warnings being output here, but this won't really prevent us from proceeding. IMO, it's probably isolated to a few shapes, but I haven't really meaningful looked that deep into it.

Check out the unique LGA names¶

Sometimes LGA names are not represented how you'd expect, so lets just see what the naming convention is within these files.

Plot an LGA¶

Now wrap up by using the data to plot an LGA. Lets do the the Inner West Council, judging by the output about it's just represented as "INNER WEST".

What kind of plot do we want to do?¶

Let just show the zoning, as well along with heritage information such as heritage conservation areas and such. Apparently there's also "Archaeological" and "Landscape" items, but I'm not quite sure what to make of those.
