2. A day in the Indian Railways Network
Animating Rajdhani trains 🚆 moving from and to New Delhi. Data: data.gov datameet.
3. Literacy in India
Understanding the picture at district level from census data. Just over a quarter districts have literacy above 70%. data: Census 2021
4. Access to healthcare
Visualizing concentration of hospitals across India. Data: nhpindia
5. Elevation of Rivers
Attempt to understand changing heights of Indian Rivers from openstreetmap and DEM data.

How green are Indian cities? Looking at spaces including parks, forests, recreation grounds, etc. within 25km grids. Data: openstreetmap
8. Solar Potential in India
Visualizing direct normal solar irradiance throughout the year with current installed capacity of solar plants. Data: NREL, WorldResources, mnreindia
9. Air Quality in India

10. Plant Growth Patterns
Changing green vegetation in India. NDVI data from NASAEart
11. Hills of southern India
Visualizing exaggerated terrain model over OpenStreetMap map ⛰️
12. Visualizing rainfall patterns in India with PowerPoint
Slides and objects are auto-generated from data.😃 data: Indiametdept
13. 30 Years of Ganga Koshi Confluence
Tracing changing river courses from Landsat imagery. Uses band combination of SWIR1,NIR,Red for color.
14. Rainfall Anomaly in India
Tracking unpredictable rainfall changes. We compare annual rainfall deficits since 2001 with average baseline of 1980-2000.
15. The Toy Train Connection
Built in the 1880s, this mountain railway spanning 88km connects New Jalpaiguri (100m) to Darjeeling (2,200m elevation)
16. Islands of Power held by Women
A look at constituencies that have elected at least one woman MP since 1962. There are still ~50% constituencies yet to elect a woman MP to the Indian Parliament.

Interesting to see how the terrain separates the kingdoms of Malabar and Carnatic from Mysore empire, and Northern Sarkars and Nizams from the Marathas.
Historical map from 1923 Atlas.
18: India’s Urban Sprawl
Understanding how Indian cities have grown from 1985 to 1995 and to 2005, using land cover and land use data. Data: NASAEarth DAAC ORNL
19. Areas without Train Stations
These are 30x30 km grid areas in India without a train station.
20: Population density of India
Pretty conspicuous that northern India across the fertile plains of river Ganges is much more densely packed than the rest of India. Data: GHSL 2015 estimate.
21: Dams of Central India
A look at how dams are built around some of the major rivers of India. Data: GRanD, OpenStreetMap
22. Migration in India
Mapping Inter-State migratory movements. Interesting to see that apart from Delhi and Mumbai, most state migrations happen just around the state borders.
23. Nearest Capital-based Boundaries
Mapping each district of India to the nearest capital city. Distance from the nearest capital city is measured from district’s center location.
24: The origins of Ganga
Alaknanda and Bhagirathi rivers meet at Devprayag (at 830m elevation) to form Ganga, and in less than 75kms, Ganga drops to 370m at Rishikesh. Data: isro cartodem, OSM
25. COVID-19 India
Trends in daily new cases reported across India. Looking at 7-day moving average of new cases at district (/city) level.
26. Density of rural facilities in India
~7 lakh facilities surveyed for PMGSY-III (Pradhan Mantri Gram Sadak Yojana). Kerala’s density outshines pretty blazingly.
27. Mapping #OpenStreetMap’s Point Features
Understanding 561,068 points coverage. Lots to learn from #Kerala’s community mappers. Karnataka, AP, Telangana and parts of Chhattisgarh have relatively decent coverage.
28: Vertical Pixel Sorting by Color Brightness
Terrain color histogram by column / longitudes. Source: ESRI
29: First successful voyage to India
In 1497, Vasco da Gama started from Lisbon, Portugal and reached Calicut a year later via the Cape of Good Hope.
