Explorations in QGIS - 1 (assignment)

[pkd2512]

• Make a map of India and states. (Mercator projection)
• Highlight a state (home/residence/other) and a city (residence/capital/other)
• Add graticules (lat-lon) to your map as required.
• Use the datasets from Natural Earth to add some rivers or anything that might be of interest (Explore)
• Add labels and styling as required.

India and states

State highlighted and labelled

My Assembly Constituency and district borders are highlighted

Graticules and national highways

[sashacherian]

Airports categorised based on the size - medium and large

Himalayas and the Rivers

[harnehmat]

Tried to show:

1. Disputed areas
2. 3 longest rivers
3. 3 largest states
4. 3 largest cities

Showing small, medium and large airports across the states. Tried rule based labelling for large and medium airports and size as per that as well by assigning numeric value to them. ~ The South has more large airports! ~ The largest state does not have any large airports!

Showing:-

1. Disputed borders
2. Rivers in my City
3. State and City
4. Labels

Airport data:-

steps taken:-

1. Read CSV file
2. filtered on airports in India
3. filtered on type "closed" and "heliports"
4. converted elevation column, which was read as "qstring" to "double"
5. mapped converted elevation data to the size of the airport points
6. changed the opacity of points to 50% to avoid overlapping
7. Applied filters on labels, for airports where elevation is greater than 1000

Most populated neighbourhoods in bangalore:

Continuing on Bangalore basemap - mapped BBMP schools dataset from Open Cities and tried to practice things we walked through in class:

• Coded markers by to size / colour according to language category
• Used dissolve and clip mask to show only Bangalore Urban Schools
• Imported csv to and joined it to existing attribute table in qgis to attach language, gender, school level data to shape file
• Exported and refine in illustrator (faced lot of issues, very irritating!). Map Composer helped.

Visit this link for process screenshots.

Feedback:

1. Cannot make certain categories' markers larger than others because the data is uni dimentional. Try to find some other way to make those schools visible, eg. tie it to number of children in each school (find this data!)
2. Purple base-map is creating lot of noise. Try something more subtle to make the data show up better
3. Have annotations with few insights to handhold the reader through the map reading. Even if they aren't able to make sense of the chart, they can still make out what you are trying to show.
4. Stacked bar chart is fine but the columns are not clear. Try it has horizontal bars with clearer labels. No need to add language labels since the legend is on top.
5. Avoid tilted labels!
6. Incorporate scale for city level maps. Can also include a locator map according to the audience of where Bangalore is. (Country / World map)
7. Mention the data sources!

Exploration!

Refined on Illustrator Showcasing:

• Districts, states, and country boundaries with various stroke weights and types.
• Disputed area
• Special attention to 2 districts - Banglore and Gautam Budh Nagar

Problem faced: Unable to label the specific districts on QGIS (Banglore and Gautam Budh Nagar in this case)

Explorations (assignment and jamboard)!

1. Assignment
   • Figuring out the national borders (India Map)
   • Highlighting states and their names/labels
   • Highlighting my birth-state (Maharashtra)
   • And birth-town (Nagpur, Vidarbha district) area over the state
   • Exploring graticules and roadways over these all.

2. Jamboard explorations

QGIS Exploration

• Loaded map data and added a OSM background

• Imported district view and played around with color depths

• Labeled and Formatted the map, made it printable at A4 scale

• Made a small data viz of nuclear power plants in Indian and their capacities

This was great to see! Thanks @pkd2512 for documenting this in issues. Closing this now.
