Overview

See the Earth from Space, Act on the Ground

Remote sensing is the science of acquiring information about Earth's surface without direct physical contact — using electromagnetic radiation detected by satellite or airborne sensors. The data it provides is irreplaceable for monitoring large areas quickly, detecting change over time, and understanding phenomena invisible to the naked eye.

Planora accesses data from 15+ satellite constellations ranging from free 10m Sentinel-2 imagery to commercial sub-metre WorldView-3 and Planet Labs daily captures. We process optical, multispectral, hyperspectral, thermal, and SAR (radar) datasets across the full analytical spectrum.

Our remote sensing team combines ENVI, Google Earth Engine, and custom Python/R pipelines to deliver land cover classifications, vegetation indices, change detection maps, and time-series analyses that support decisions at every level of government and enterprise.

🛰️

Planora has processed over 80,000 sq km of satellite imagery for agriculture, forestry, environment, and urban monitoring projects in the last 5 years alone.

Workflow

Our Analysis Pipeline

01

Imagery Selection & Procurement

Identifying optimal satellites, dates, and cloud-cover thresholds. Free Sentinel/Landsat data is downloaded directly; commercial imagery is procured from Maxar, Airbus, or Planet as needed.

02

Pre-Processing & Calibration

Radiometric calibration, atmospheric correction (FLAASH/DOS), geometric correction, orthorectification, and pan-sharpening. All processing is done to Level-2 surface reflectance standard.

03

Index Computation & Band Analysis

Generating vegetation indices (NDVI, NDRE, EVI, SAVI), water indices (NDWI, MNDWI), built-up indices (NDBI), and spectral band composites for visual interpretation.

04

Classification & Feature Extraction

Supervised (Random Forest, SVM), unsupervised (K-means, ISODATA), or object-based (eCognition) classification as appropriate. Deep learning classification using DeepLabv3+ for high-res imagery.

05

Accuracy Assessment & Validation

Producer's, user's, and overall accuracy calculated from stratified random sample of field-verified reference points. Kappa coefficient and confusion matrix reported for all classifications.

06

Map Production & Reporting

Final classified maps, change detection outputs, and index rasters produced in GIS-ready formats. Full analysis report with methodology, accuracy statistics, and interpretation guidance.
