Geoflow

Flowchart tool for geo-spatial data processing. Highly experimental with many rough edges!

Installation

Using the precompiled binaries for Windows

This is the easiest way to get Geoflow running on Windows. Simply download and run the Geoflow installer from the latest release. Launch geoflow.exe to start Geoflow.

Installing and using plugins

Geoflow plugins provide the nodes for Geoflow. Nodes are the functional parts of the flowchart that implement a specific function. You can find the plugins on the geoflow3d organisation page. The plugin repositories have the gfp- prefix, that is an acronym for geoflow plugin.

To use plugins you need to do this:

Set an environment variable called GF_PLUGIN_FOLDER that points to a directory where you will put the plugins, e.g. C:\Users\<USERNAME>\.geoflow\plugins.
Download the plugin from the plugin repository, eg. the LAS plugin. Currently a plugin on Windows is simply a .dll file.
Copy the plugin file, eg. gfp_las.dll to the GF_PLUGIN_FOLDER folder you set up earlier.

Geoflow should automatically load all plugins that it finds in the GF_PLUGIN_FOLDER folder. Notice that a new version of geoflow may also require a new version of a plugin.

Building from source

Requires compiler with c++17 support (see https://en.cppreference.com/w/cpp/compiler_support).

mkdir build
cd build
cmake .. -DGF_BUILD_GUI=[ON|OFF]
cmake --build . --parallel 4 --config Release

Building with GUI

Requires additional dependencies glm and glfw that need to be installed by the user.

Platform specific instructions

Have a look at the workflow files.

Usage

Command line interface (`geof`)

geof <flowchart file> [--config <TOML config file with globals>] [--GLOBAL1 <value> --GLOBAL2 <value> ...]

You can also simply print just information on the plugins that are loaded with: geof info

GUI (`geoflow`)

Takes the same parameters as geof on the command line.

Right click to open the menu to create new nodes
Drag from input/output terminals to make connections
Right click on a node to access its context menu
Translate in the 3D viewer by left-mouse dragging while holding ctrl, faster zooming by holding ctrl while scrolling.
