# Documentation for the Anaximandre plugin

# Introduction

The Anaximandre plugin enables the creation of 3D polygon, line and point geopackage files (.gpkg) from a points layer in csv format. The points must include, in addition to their coordinates, descriptive values which allow them to be grouped, and a code value which defines the geometry to be generated. The codes are:

- For a polygon : ‘p’
- For a line : ‘l’
- For a point : ‘pt’
- For linked reference points : ‘pt cpe’
- For an isolated artefact : ‘iso’
- For a DEM point : ‘pt mnt’
- For a circle : ‘c’, followed by its diameter in meters
- For a circle from two points: ‘c2pt’

The order of the points in the file must follow a few rules:

- The points must follow the outline of the intended line or polygon
- For circles, the center of the circle will be used
- For DEMs, there is no particular order

The result will be a group of layers containing 3D entities as well as the following attributes:

- First description (e.g. context number)
- Second description (e.g. type)
- Average Z

# The dialog box

The plugin requires two initial parameters:

- a csv file: CSV File
- The location for the output files: Output

When a csv file is selected, the data in the first line of the file are shown in order to verify their conformity

The OK button launches the program and loads the layers onto the map
