DIGENTI Apps\n\nOpen-source web-based tool for area accessibility assessment in the context of disaster management – based on satellite data and geovisualization.\n\nThe 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.\n\nMoreover, the repository includes a set of snippets and examples, including routing experiments combining a routing API and remote sensing data.\n\n## Accessibility Interface\n\nThe Accessibility Interface is located in `app-access`.\n\nThe interface visualizes for each settlement:\n\n- Accessibility by road (vehicle)\n- Accessibility by path (walk)\n\n*Overview of the accessibility of each settlement in the area:*\n\u003cimg width=\"1324\" alt=\"Area accessibility overview\" src=\"https://github.com/FH-Potsdam/digenti-apps/assets/859148/a3c1888d-97e3-4ff5-b827-a7b4095f8646\"\u003e\n\n*Reachability of a settlement by road with time isolines:*\n\u003cimg width=\"1324\" alt=\"Settlement reachability\" src=\"https://github.com/FH-Potsdam/digenti-apps/assets/859148/ebcceaae-66e4-49a1-a45e-c1bfbf73f287\"\u003e\n\nIf a settlement is **not directly accessible** by road:\n\n1. Provide accessibility data to the nearest road:\n    - Distance\n    - Elevation profile\n    - Passable areas (%, polygons)\n    - Walkable areas (%, polygons)\n2. Provide helicopter landing areas (within a given distance from the settlement)\n\n*Data to the settlement's nearest road:*\n\u003cimg width=\"1324\" alt=\"Missing settlement reachability\" src=\"https://github.com/FH-Potsdam/digenti-apps/assets/859148/6dbadf05-6ff5-44c5-a57c-228c4fcf6836\"\u003e\n\n*Potential helicopter landing sites around a settlement:*\n\u003cimg width=\"1324\" alt=\"Potential helicopter landing sites\" src=\"https://github.com/FH-Potsdam/digenti-apps/assets/859148/638af0bf-cf43-4a32-ae99-fb404623cae2\"\u003e\n\n*Summary of the remote sensing data-based routing concept:*\n\u003cimg width=\"685\" alt=\"DIGENTI_RemoteSensingRouting\" src=\"https://github.com/FH-Potsdam/digenti-apps/assets/859148/ccda1126-f827-4644-840e-dd3da3f23620\"\u003e\n\n## Dependencies\n\nThis is the client part of a modular architecture. In order to access the satellite data you'll need to install the following packages:\n\n- [DIGENTI Framework: Libs, commons and utils](https://github.com/FH-Potsdam/digenti-framework)\n- [DIGENTI Server and REST API](https://github.com/FH-Potsdam/digenti-api)\n- [PostGRE / PostGIS Database](https://redmine.geoway.de/projects/digenti/wiki/Notes)\n\n## Docs\n\nFurther information of the project can be found in the following research articles and documentation:\n\n- [Project Documentation](https://github.com/FH-Potsdam/digenti-doc)\n- [Visualization and Interaction with Multiple Devices. A Case Study on Reachability of Remote Areas for Emergency Management – Jordi Tost \u0026 Frank Heidmann, i-com Journal of Interactive Media](https://doi.org/10.1515/icom-2017-0027)\n\n## Data\n\nThe 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.\n\n- [Data Wiki](https://docs.google.com/document/d/1rOW-6X6TNkypR-dgxWhZ4W7whIa5dxpPMbqCAW_iMPc/edit)\n- [Data Formats](https://docs.google.com/spreadsheets/d/1igPn_mZqVaId_kqjcNPapB_qUvXkHo37GfP1JvSQrOs/edit?usp=sharing)\n\n## Tools\n\n### Geo tools\n\n- [Mapbox GL JS](https://www.mapbox.com/mapbox-gl-js/)\n- [Turf.js](http://turfjs.org/)\n\n### Routing\n\n- [HERE Routing API](https://developer.here.com/rest-apis/documentation/routing)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffh-potsdam%2Fdigenti-apps","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ffh-potsdam%2Fdigenti-apps","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffh-potsdam%2Fdigenti-apps/lists"}
