Ecological indexing as an instrument of resistance to climate change
EAASI companies: MapSoft and Teledyne Geospatial
Categories: Urban Planning, Climate Change
Project Overview
MapSoft completed an innovative project for the Association of Landscape Architects in Serbia to quantify Belgrade's green infrastructure as a countermeasure against climate change. This project responds to the city’s loss of permeable surfaces, aiming to guide urban planning policies that support green infrastructure and reduce pollution.
Utilizing Teledyne Geospatial's Optech Galaxy system on a fixed-wing aircraft, Mapsoft collected comprehensive geospatial data, producing urban landcover maps, 3D models, rooftop classifications, and detailed tree analysis. This allowed for scenario modeling, helping policymakers visualize the impact of increased vegetation on urban health.
Results and Impact
The rich data derived from this project enabled the calculation of an Ecological Index, indicating the health of city plots. This index offers a baseline for sustainable urban planning, supporting bylaws that encourage green infrastructure to enhance air quality and residents’ quality of life.
Competitive Advantage of Crewed Aerial Surveying
Crewed aerial surveying facilitated the collection of extensive data over the entire city within a short timeframe, providing the necessary detail to analyze urban green spaces, vegetation density, and landscape features—key insights unattainable through satellite or ground-based methods.
Lidar-derived vectors of one of the neighborhoods of the study. The map shows various features, like building footprints, roof slope, porous and non-porous ground, grassed ground, and importantly location and crown of trees. The grey-scale map shows low Ecological Index (grey) and high Ecological Index (green). It is interesting that areas with the highest vegetation had the highest Ecological Index. The large grey area (low Ecological Index) reaffirms the motivation of this project, which is that urban spaces lack greenery and require it to reduce pollution and increase quality of life.
