Hi community, I need your help. I'm using QGIS 3.10.11 with Grass 7.8.4. I'm building a QGIS modeler and I want to calculate the area of an input polygon.
So, my input polygon is a vector feature. I tried using a field calculator ($area) and Advanced Python Field Calculator (Field "Formula", I used "value = $geom.area() ). However, nothing is working. When I run the modeler, there is no error message. But, I'dont have the area calculated either. Thanks for your help. -- See our last paper: <https://doi.org/10.1016/j.envpol.2020.114029> Impact of biomass burning on a metropolitan area in the Amazon during the 2015 El Niño: The enhancement of carbon monoxide and levoglucosan concentrations. <https://doi.org/10.1016/j.envpol.2020.114029> Igor Oliveira Ribeiro Post-Doc on Regional Climate Change, Vulnerability, Impacts and Adaptation - Cuomo Foundation/UEA +55 92 98103 7136 | skype: igorflorestal Universidade do Estado do Amazonas | Instituto Nacional de Pesquisas da Amazônia Visite: www.geoescrita.com.br <https://www.linkedin.com/in/igoroliveiraribeiro/> <https://www.instagram.com/geoescrita/> <https://www.researchgate.net/profile/Igor_Oliveira_Ribeiro> <http://lattes.cnpq.br/3909691804095045> <https://orcid.org/0000-0002-3529-0525> <https://www.geoescrita.com.br/> Think globally, act locally!
