About Emily-Jane

Geomatics Engineer & GIS Developer
- Remote Sensing · Python · QGIS · Lidar -

Graduated from the National School of Geographic Sciences (ENSG) with a specialization in geo-imaging and photogrammetry, I offer freelance services in GIS development, geospatial data processing, and remote sensing.
My skills cover the entire geomatics chain: field data acquisition (GNSS, drone, photogrammetry), processing of Lidar HD and ortho-image data, development of QGIS tools and plugins in Python, hydraulic modeling (watersheds, flows), and data visualization.
I have had the opportunity to work on various projects: developing a climate diagnostic tool for an engineering firm, delineating the public river domain in Reunion Island for DEAL, estimating forest biomass in Lisbon, and detecting old forests using machine learning in partnership with Dynafor researchers.
Comfortable in both institutional (state services, research) and private company environments, I adapt quickly to contexts and tools. Rigorous and curious, I enjoy assignments that combine environmental challenges with technical development.
