Clementina
Patagónica
Drone-based environmental monitoring with centralized processing.
We centralize drone surveys and derived products to build comparable environmental monitoring and generate useful information for science and conservation.

A growing network
Drone surveys already integrated in the platform.

patagonia costeraFrom fieldwork to the public map
Three steps to transform drone images into accessible environmental products and monitoring.
You upload your images
Upload RAW or JPG images directly after a field trip. The platform organizes extensive surveys and heavy files without manual splitting.
We process in Clementina
We generate georeferenced products from your images and you follow processing in real time. All results stay linked to the original survey.
We publish the map
Define the access level for the survey (public, collaborative or restricted). Derived products remain available with clear licensing and traceability, while the original images are safeguarded without being published.
What you receive once your flight is processed
One upload, three open and citable formats.
JPG preview
~10-20 MBTo view the map in a browser, share by email or include in an article. No special software needed.
GeoTIFF orthomosaic
~200-600 MBTo open in QGIS, ArcGIS or any GIS. Every pixel carries real coordinates.
GeoPackage layers
~50-150 MBFor quantitative analysis: contours, transects, vectorized points of interest.
Digital elevation models
Beyond the orthomosaic, each survey can generate a georeferenced Digital Elevation Model (DEM) and JPG previews. DEMs provide terrain height information and are the basis for erosion, hydrology and morphological change analyses.

Three access levels, you decide
Each survey you upload carries a level. You set it on upload and you can change it later.
Public
Visible on the open map. Anyone can explore and download the derived products. Your authorship is explicit.
When: monitoring of non-sensitive areas, institutional coverage, outreach.
Collaborative
Visible to registered network members. Others can request contact to collaborate or ask for access to the material.
When: ongoing work, thesis data, campaigns you want to share with peers before publishing.
Restricted
The survey perimeter appears on the map, but the products are safeguarded. Held under institutional custody.
When: archaeological sites, threatened species, public security data.

Four steps to your first survey
No prior meetings, no long forms. If you already have images on a disk, you can start right now.
- 01
Read the protocol
Fifteen minutes. Download it as PDF and take away the key parameters: altitude, overlap, speed.
- 02
Fly the grid
If you already have campaigns shot with a similar protocol, those work too. Check the minimum requirements.
- 03
Upload from your disk
Create account, create survey, drag the folder. No manual chunks, no FTP.
- 04
Wait for validation
We notify you once approved. Meanwhile, you can upload the next campaign.
From raw photo to three-dimensional model
Every flight follows the same path: overlapping images, georeferenced map with elevation, navigable three-dimensional fly-through.
Overlapping images
Hundreds of photos with GPS metadata, captured on a grid with 70% overlap. That overlap is what makes the reconstruction possible.
Orthomosaic plus DEM
The orthomosaic is the flat georeferenced map. The DEM (Digital Elevation Model) records the height of every pixel.
Three-dimensional reconstruction
Combining orthomosaic and DEM yields a navigable 3D model that preserves the real proportions of the terrain.
Flat maps today, 3D fly-through tomorrow
Phase 1 publishes orthomosaics and DEMs. The next phases enable comparative analysis and a three-dimensional viewer inside the browser.
Phase 2 — Quantitative analysis
Change detection across flights, automatic transects, temporal coast comparison, assisted counts.
Phase 3 — 3D viewer in the browser
Navigable fly-throughs over any published survey. No special software. Just the browser.

Organizations making the platform possible
Scientific, academic and conservation institutions supporting the development and growth of Clementina Patagónica.
Open data, with responsibility.
We apply two complementary frameworks: FAIR, so data is findable and reusable, and CARE, so its use respects those who generated it and the territories it documents. At Clementina, this translates into concrete decisions.
Findable and reusable (FAIR)
Each published survey includes its suggested citation, visible CC-BY 4.0 license and open formats (GeoTIFF, JPEG, PDF). Products can be downloaded, reused and cited while maintaining traceability.
Access under author control (CARE)
Original images are never published. The author defines which products are visible and under what conditions they are shared, while the original material remains safeguarded under institutional custody.
Three access levels, not just one
Public allows exploring and downloading derived products from the open map. Collaborative enables contact between users and authors to generate collaborations and share access to specific surveys. Restricted keeps visible the existence and perimeter of the survey, but protects its content when dealing with sensitive sites or information under study.
How to cite Clementina Patagónica
If you use data from the network in a publication, please cite the project along with the specific survey.

Why "Clementina"?
Clementina Patagónica takes its name from Clementina, the first scientific computer used in Argentina, driven by Manuel Sadosky at the University of Buenos Aires in 1961. Decades later, a homonymous computer once again processes scientific data, transforming drone surveys into geospatial products for environmental monitoring and conservation.
More than a historical reference, the name recovers an Argentine tradition of science and technology at the service of knowledge, territory, and the construction of public capacities.
“We propose to develop a science and a technology at the service of the country, to enable and structure its development.
