## Description
AHN CLI is a command-line interface tool designed for the effortless downloading of AHN (Actueel Hoogtebestand Nederland) point cloud data for specific cities and classification classes.

```
pip install ahn_cli
```
## Usage
To utilize the AHN CLI, execute the following command with the appropriate options:
```shell
Options:
-c, --city Download point cloud data for the specified city.
-o, --output Designate the output file for the downloaded data.
-i, --include-class Include specific point cloud classes in the download,
specified in a comma-separated list. Available classes:
0:Created, never classified; 1:Unclassified; 2:Ground;
6:Building; 9:Water; 14:High tension; 26:Civil structure.
-e, --exclude-class Exclude specific point cloud classes from the download,
specified in a comma-separated list. Available classes as above.
-d, --decimate Decimate the point cloud data by the specified step.
-ncc, --no-clip-city Avoid clipping the point cloud data to the city boundary.
-cf, --clip-file Provide a file path for a clipping boundary file to clip
the point cloud data to a specified area.
-e, --epsg Set the EPSG code for user's clip file.
-b, --bbox Specify a bounding box to clip the point cloud data. It should be comma-separated list with minx,miny,maxx,maxy
centered on the city polygon.
-p, --preview Preview the point cloud data in a 3D viewer.

### Usage Examples
**Download Point Cloud Data for Delft with All Classification Classes:**
```
ahn_cli -c delft -o ./delft.laz
```
**To Include or Exclude Specific Classes:**
```
ahn_cli -c delft -o ./delft.laz -i 1,2
```
**For Non-Clipped, Rectangular-Shaped Data:**
```
ahn_cli -c delft -o ./delft.laz -i 1,2 -ncc
```
**To Decimate City-Scale Point Cloud Data:**
```
ahn_cli -c delft -o ./delft.laz -i 1,2 -d 2
```
**Specify a Bounding box for clipping:**
If you specify a `b`, it will clip the point cloud data with specified bounding box.
```
ahn_cli -o ./delft.laz -i 1,2 -b 194198.0,443461.0,194594.0,443694.0
