Mumbai's Open Space: How Much Public Ground 1.6 Crore Residents Actually Share

Mumbai looks green from above, but only about 6% of its 154 km² of mapped green is public open space anyone can walk into. Run through Terrastack's catchment intelligence engine, the city resolves into what each resident actually shares: a hectare of park within 1 km is crowded by about 22,000 people for the median Mumbaikar, and roughly 81,000 in the most crowded fifth of the city. It separates the two failures, distance and crowding, across housing formality, shops & services, flat prices and informal settlements, ranks all 36 constituencies, tests what open space is worth in the property market, shows that only 8% of new housing projects are going to that crowded fifth, and sizes the gap at roughly 105 additional hectares.

A Spatial Graph Clustering Pipeline for Urban Morphology Analysis

A full pipeline for clustering 747,263 building polygons across the Mumbai Metropolitan Region into spatially contiguous, socioeconomically homogeneous neighbourhoods. The report covers Delaunay proximity graph construction, Fisher-ratio weighted edge similarity, grid-based decomposition with recursive spectral bisection, and a multi-phase cluster refinement procedure including bidirectional flow diffusion. It also documents the geographic contiguity layer built on alpha shapes, Automatic Zoning Procedure (AZP) with simulated annealing, and Voronoi tessellation to produce gap-free urban regions, validated against CV, conductance, flow retention, purity, and spatial metrics.

Terrastack Bio-Residue Estimation System: Scientific Methodology and Technical Architecture

Technical documentation of Terrastack's geospatial API system for agricultural biomass estimation. This report details the scientific methodology for converting satellite-derived plot data into actionable biomass inventory, covering residue quantification methods (IPCC Linear Model, Harvest Index, RPR), yield fallback hierarchy (CCE → APY → National Averages), system architecture, and validation through Yavatmal case study. Designed for biomass aggregators, pellet manufacturers, and sustainability consultants.

Agricultural Production Data Quality Assessment Report

A comprehensive quality assessment of Area, Production, and Yield (APY) datasets from the Directorate of Economics & Statistics (DES). This report analyzes district-level data from 2020–2024 and historical state-level data from 1966–2025, examining coherence between district and state aggregations, long-term yield trends, CAGR analysis, and spatial multiplier patterns across India's agricultural regions.

Comparative Analysis of Crop Cutting Experiments and Agricultural Production Yield

An in-depth validation study comparing Crop Cutting Experiment (CCE) field measurements with official Agricultural Production Yield (APY) statistics across India. This report examines systematic deviations between CCE and APY data, analyzes crop-specific and state-level discrepancies, evaluates conversion multipliers, and assesses data quality and coverage patterns to understand the reliability of agricultural yield reporting systems.
