CiTree - Recovering the green in the city
CiTree is a geoportal that allows monitoring forest cover in urban areas. We create this plataform for Governments and non-governmental organizations who are leading decisions in sustainable management and biological corridors establishment.
Who we are?
CiTree is integrated by Leonardo Castro, Douglas Rojas, Mariana Jiménez, Ronald Vargas -forestry engineering students, and Carlos Mata -design engineering student. All of us, originated from Costa Rica, want to contribute to maintain the sustainability in the world through new technologies oriented to recover the green in the cities.
The challenge
- The urban expansion in the world due to demographic growth and expansion of industries have caused loses in the forest cover affecting directly to the biodiversity, carbon stock and wildlife.
- Lack of updated information about profits and loses of forest cover neither efficient technologies that provide solutions to connect the green patches over the cities.
our solution
CiTree provides precise information about the current state of forest cover in urban areas comparing satellite images in different periods. It generate statistics and results about the profits and loses of forest cover in determinate areas as well as obtain optimal areas for reforestation aimed to connect forest patches through biological corridors.
WHY it'S IMPORTANT?
CiTree is important to monitor forest cover in cities and seeks the conservation of these areas, since urban growth is currently taking place in an uncontrolled manner and at the same time the forest areas are being unprotected.
The geoportal can be used by local governments, public institutions, research centers, ONG'S, companies that work with natural resources and also companies dedicated to reforestation in urban areas.
HOW DOES IT WORK?
CiTree works with high resolution images and using different algorithms to obtain two different services.
1. Forest cover monitoring. CiTree will allow you to select two different periods in a same location. In this way, it will compare the two images through pixel analysis, and if any change of cover occurred between that time lapse, it visualize the changes in green color when the forest cover increases or red color if the forest cover reduces.
2. Forest patches connectivity. CiTree also identifies the green patches distributed in the selected area and prioritizes optimal areas to connect these through geoespatial analysis based on ecological and biophysical criteria.
RESOURCES
- Satellite images such as Landsat 8, MODIS, Sentinel-2, Pleaides-1A and Pleaides-1B for monitoring forest cover in urban areas (https://eos.com/landviewer/?lat=9.85552&lng=-83.90062&z=18&preset=highResolutionTmsSensors&purchase-tms-scene=b4abef41408b7dca6d8daf3e7cf2791b).
- MED data such as ASTER Global Digital Elevation Model (https://search.earthdata.nasa.gov/search?q=ASTGTM_NUMNC%20V003).
- Climatic data such as the SERVIR Data Catalog (https://www.servirglobal.net/SERVIRLogin?returnurl=%2fGlobal%2fMaps-Data), It can be obtained to create predictive climate models that lead us to better decision making.
WHAT'S NEXT?
CiTree pursues the establishment of sustainable and energetic efficient cities over the world.
