Caldra

Caldra is a live temperature heatmap. Search a city, then color the map by temperature, feels-like, or humidity for now, +6 hours, or +24 hours. Cool to hot runs on a clear key so you can see the hot pocket without reading a weather table.

Caldra ↗
TL;DR
  • Customer: Someone who needs a live heat field for a city or region, not a single thermometer reading.
  • Problem: A city temperature is one number. The hot and cool pockets sit next door.
  • Solution: A live map colored by temperature, feels-like, or humidity, with time and focus controls.
  • Outcome: You can switch metric, unit, and time, and read min, mid, and max on the key.
  • Strategic win: The same board covers now and the next day without opening another weather site.

The problem

The city said 30°. The map did not.

Operations, events, and travel teams often get one temperature for a whole metro. The useful question is where it is hotter or more humid right now, and where that moves in the next day.

One number, many pockets Coast, inland, and elevation do not share one reading.
Feels-like is its own metric Humidity can make the same temperature feel different across the map.
Later today matters A plan for +6 or +24 hours needs the field, not only the current pin.
Live Temperature field for the time you pick
3 Metrics: temp, feels-like, humidity
+24h Now, +6 hours, or +24 hours
Key Min, mid, and max on screen

Why it was hard

One city reading hides the gradient. Feels-like and humidity are different stories from the thermometer, and tomorrow morning is not the same map as now.

  • A single station reading is not a field
  • Feels-like can diverge from the thermometer on humid days
  • A forecast hour needs the same color language as now
  • Near and wide focus change what the key should report

What you get

  • ✓Search a city and color the map by temperature, feels-like, or humidity
  • ✓°C or °F
  • ✓Now, +6 hours, or +24 hours
  • ✓Near or wide focus, map or satellite, admin areas or heat field
  • ✓Cool-to-hot key with min, mid, and max for what is visible
01

Search, then color

Type a city. Caldra paints the field for temperature, feels-like, or humidity. The headline shows the place, the metric, and the live time.

02

Time and focus

Now, +6 hours, and +24 hours sit next to near or wide focus. The cool-to-hot key updates min, mid, and max for what you can see.

03

Same board, other cuts

Country, division, or district, map or satellite, admin areas or heat field. The metric controls stay put so you are not learning a new weather site for each cut.

In short

A live heat field, not one thermometer pin.

Caldra colors a city or region by temperature, feels-like, or humidity for now and the next day, with a key that matches what is on screen.

Caldra is a portfolio sample of live heatmap interfaces we build. Readings change with the clock and your location; the screens show the demo controls and cool-to-hot key.

Big ideas, byte solutions.

BigiByte is a team of engineers in Dhaka, Bangladesh, working with clients worldwide. We build the tools that collect information, find customers and take repeated work off people's plates.

The BigiByte team working together around a table: pair programming, whiteboarding a data pipeline and on a client call

We started by fixing our own data problems.

Most teams don't need another tool. They need the data already sitting on the web, delivered cleanly to where they work. That's what we build: tools that keep working when websites change, automations nobody has to watch, and products built on top of reliable data.

We also publish ready-to-run scrapers on the Apify Store, like our StreetEasy and Google Search Results scrapers, used by teams every week.
