# DIGENTI Apps
Open-source web-based tool for area accessibility assessment in the context of disaster management – based on satellite data and geovisualization.
The tool gives an overview of the accessibility of the settlements in the [Area of Interest in Colombia](https://docs.google.com/document/d/15N1pgERY4TUcnvck36jJFi3MvAZuxh8J-mOUpWDt-_w/edit?usp=sharing) using a routing API and remote sensing data.
Moreover, the repository includes a set of snippets and examples, including routing experiments combining a routing API and remote sensing data.
## Accessibility Interface
The Accessibility Interface is located in `app-access`.
The interface visualizes for each settlement:
- Accessibility by road (vehicle)
- Accessibility by path (walk)
*Overview of the accessibility of each settlement in the area:*
*Reachability of a settlement by road with time isolines:*
If a settlement is **not directly accessible** by road:
1. Provide accessibility data to the nearest road:
- Distance
- Elevation profile
- Passable areas (%, polygons)
- Walkable areas (%, polygons)
2. Provide helicopter landing areas (within a given distance from the settlement)
*Data to the settlement's nearest road:*
*Potential helicopter landing sites around a settlement:*
*Summary of the remote sensing data-based routing concept:*
## Dependencies
This is the client part of a modular architecture. In order to access the satellite data you'll need to install the following packages:
- [DIGENTI Framework: Libs, commons and utils](https://github.com/FH-Potsdam/digenti-framework)
- [DIGENTI Server and REST API](https://github.com/FH-Potsdam/digenti-api)
- [PostGRE / PostGIS Database](https://redmine.geoway.de/projects/digenti/wiki/Notes)
## Docs
Further information of the project can be found in the following research articles and documentation:

## Data
The remote sensing data is based on the Tandem-X WorldDEM 10-m resolution digital elevation model (DEM) with complete coverage for the area of interest.
