I will land cover classification, change detection and indices map
Bairavy Aru
About this gig
Land use / land cover mapping, time series analysis, change detection and vegetation index analysis with training samples, an accuracy assessment and a methods write-up, not just a coloured raster.
Classification & change detection
- Supervised (Random Forest, SVM, Max. Likelihood) or unsupervised classification
- Multi-date change detection with a change matrix what became what, in hectares and percent
- Confusion matrix, overall accuracy, producers/users accuracy, kappa
Vegetation & other indices
- NDVI, EVI, SAVI (vegetation/crop health) · NDWI, MNDWI (water) · NDBI (built-up) · Land Surface Temperature or whatever the indices at your request
- Single-date or time series, with zonal statistics per field/district
Imagery: Sentinel-1,Sentinel-2, Landsat 5/7/8/9, ASTER, MODIS sourced free, or I work with imagery you supply.
You get: classified/index raster (GeoTIFF), a laid-out map (PNG/PDF), Excel statistics, a change matrix where relevant, an accuracy assessment, and a methods paragraph for your report or paper.
Software: SNAP, QGIS, ArcGIS Pro

I am currently pursuing an MSc in the field of GIS and Remote Sensing and am based in Germany. I turn satellite, spatial and water-chemistry data into maps and analysis you can defend in a report, a paper or a client meeting.
What I do: land cover classification & change detection, NDVI/vegetation indices, georeferencing, DEM/terrain analysis, publication-quality cartography, PHREEQC geochemical modelling, and Piper/Durov/Stiff/Schoeller diagrams.
Tools: QGIS, ArcGIS Pro, SNAP, PHREEQC, Python.
I work in CET and reply the same working day.

FAQ
Do I need to provide the satellite imagery?
No — Sentinel-1 and 2, Landsat and other free imagery are sourced for you; I can also work with imagery you supply.
How accurate will the classification be?
I always deliver a confusion matrix and overall accuracy so you see the real number. If the imagery won’t support what you need, I’ll tell you before you order.
Can you do both classification and vegetation indices in one order?
Yes — that’s exactly what this gig covers; tell me which outputs you need in the requirements.
