# overturemaps italy
On this page you will find the links to the data extraction of the first release of OvertureMaps Foundation and all the scripts needed to replicate the operation.
The data version is [Release Overture 2023-07-26-alpha.0](https://overturemaps.org/download/).
The license for buildings is ODbL, while for places it is CDLA-Permissive 2.0.
The data is enriched with ISTAT ids and released in geopackage format.
In this repository there is also the dataset of the non-generalized Italian municipal borders at 2023 of ISTAT (CC-BY license) in geoparquet format.

## process
### prepare the data
Install [AWS CLI](https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html) and download the data
If you want download all
```
aws s3 cp --region us-west-2 --no-sign-request --recursive s3://overturemaps-us-west-2/release/2023-07-26-alpha.0/
```
To download single themes:
- admins
*s3://overturemaps-us-west-2/release/2023-07-26-alpha.0/theme=admins*
- buildings
*s3://overturemaps-us-west-2/release/2023-07-26-alpha.0/theme=buildings*

### process description
all data is incorporated into a duckdb file on which the following SQL operations are then performed
- extraction from the downloaded parquet files into a duckdb table taking into account the bounding box of Italy with a buffer of 5km
- from the created table, a new table is created with a selection of columns so that each contains only one value. E.g. for names you choose the languages of Italian, English, German and French
- the table is enriched with new columns corresponding to ISTAT codes through a spatial relationship with the geometries of Italian municipalities
- based on these attributes, data are extracted at the level of each Italian region
### execution
#### prepare data
bash script
```bash
duckdb omf_italy -c ".read 00_prepare_tables_istat.sql"
```
#### create geopackages of the places for earch region of Italy
bash script
```bash
duckdb omf_italy -c ".read 01_extraction_places_italy.sql"
```
#### create geopackages of the buildings for earch region of Italy
```bash
duckdb omf_italy -c ".read 02_extraction_buildings_italy.sql"
```
#### assign the SRS to each file
bash script
```bash
for i in `ls *.gpkg`;
do
name=`basename $i .gpkg`;
tmpname=`echo $name`_tmp.gpkg;
echo "assign WGS84 to $i";
ogr2ogr -a_srs EPSG:4326 -f "GPKG" $tmpname $i;
mv $tmpname $i;
echo "done!";
done
```
#### creation of geoparquet files
bash script
```bash
wget https://github.com/planetlabs/gpq/releases/download/v0.11.0/gpq-linux-amd64.tar.gz
tar xfvz gpq-linux-amd64.tar.gz
