 # viz-points
-Pythonpackage for post-processing point-cloud data for 3D visualization
+Python package for post-processing point-cloud data for 3D visualization
+
+## Repository contents
+
+- [notebooks/](notebooks/) contains the simplified and annotated Jupyter Notebook version of the LiDAR processing workflow
+- [pdgpoints/](pdgpoints/) contains the application code comprising the library
+
+## Installation
+
+### Hardware requirements
+This software requires an x86_64 architecture and a Linux environment.
+
+### Software requirements
+- [pdal](https://github.com/PDAL/python) (pip installation may not build...if so use [anaconda](https://anaconda.org/) or [miniconda](https://repo.anaconda.com/miniconda/))
+- [py3dtiles](https://gitlab.com/oslandia/py3dtiles) (Oslandia versions after [522ce61a](https://gitlab.com/Oslandia/py3dtiles/-/blob/522ce61a0c2cbeb496ba4862e14477bb941b23a3/py3dtiles/merger.py))
+- rapidlasso [las2las](https://rapidlasso.com/lastools/las2las/) and [lasinfo](https://rapidlasso.com/lastools/lasinfo/) post-November 2022 (rapidlasso [precompiled Windows](https://github.com/LAStools/LAStools/blob/master/README.md#links) or included [linux binary](https://rapidlasso.de/release-of-lastoolslinux/))
+
+Visualization requirements:
+- A tool that can display 3dtiles data, such as [Cesium](https://cesium.com)
+
+### Unix installation example
+
+Remember to set up and activate your virtual environment before proceeding.
+
+```bash
+# use conda to set up environment
+conda create -n viz-points python=3.9
+conda activate viz-points
+conda install -c conda-forge pdal
+# get and install this software
+git clone https://github.com/PermafrostDiscoveryGateway/viz-points.git
+cd viz-points
+# checkout the development branch if necessary
+git checkout develop
+pip install .
+# test your installation
+tilepoints-test
+```
+
+## Usage
+
+This software is designed to be used either as a command line tool or as a Python package.
+
+### Command line usage
+
+**Command syntax:**
+```
+tilepoints [ OPTIONS ] -f /path/to/file.las
+```
+
+**Required argument:**
+```
+    -f file.las | --file=/path/to/file.las
+            specify the path to a LAS or LAZ point cloud file
+```
+
+**Options:**
+```
+    -h | --help
+            display the help message
+    -v | --verbose
+            display more informational messages
+    -c | --copy_I_to_RGB
+            copy intensity values to RGB channels
+    -m | --merge
+            merge all tilesets in the output folder (./3dtiles)
+    -a | --archive
+            copy original LAS files to a ./archive folder
+    -s X | --rgb_scale=X
+            scale RGB values by X amount
+    -z X | --translate_z=X
+            translate Z (elevation) values by X amount
+```
+
+### Python usage
+
+**Python example:**
+```python
+from pdgpoints.pipeline import Pipeline
+
+p = Pipeline(f='/path/to/file.laz',
+             intensity_to_RGB=True,
+             merge=True,
+             archive=False,
+             rgb_scale=4.0,
+             translate_z=-8.3,
+             verbose=False)
+p.run()
+```
+
+### Visualizing the data in Cesium
+
+You can view the output tiles in a Cesium environment. For steps for how to visualize the tiles with a local Cesium instance, see the [documentation here in pdg-info](https://github.com/julietcohen/pdg-info/blob/main/05_displaying-the-tiles.md#option-1-run-cesium-locally).
+
+![Test dataset](pdgpoints/testdata/lp.png)
+
+More info on the above test dataset [here](pdgpoints/testdata/README.md).
+
+Below is an example of the `cesium.js` file that will display a 3dtiles tileset at `./3dtiles/tileset.json` (you will need your own access token):
+
+
+```javascript
+
+function start(){// Your access token can be found at: https://cesium.com/ion/tokens.
+
+  Cesium.Ion.defaultAccessToken = "YOUR-TOKEN-HERE"
+
+  const viewer = new Cesium.Viewer('cesiumContainer');
+
+  const imageryLayers = viewer.imageryLayers;
+
+  var tileset = new Cesium.Cesium3DTileset({
+    url: "3dtiles/tileset.json",
+    debugShowBoundingVolume: true,
+    debugShowContentBoundingVolume: false,
+    debugShowGeometricError: false,
+    debugWireframe: true
+  });
+
+  viewer.scene.primitives.add(tileset);
+
+  window.zoom_to_me = function(){
+    viewer.zoomTo(tileset);
+  }
+
+  tileset.readyPromise.then(zoom_to_me).otherwise(error => { console.log(error) });
+}
+
+start()
+```
