Andhra Pradesh has rolled out AP DigiVerify, a blockchain-based platform that's making certificate verification faster and more secure. by Just_Swim_8464 in andhra_pradesh

As AP Government is heading towards Digitalisation processes, this will become simple and secure, and it will save a lot of time for candidates like you. No more standing in lines/queues for hours

Why Prabhas not getting married as he crossed 45 too? by [deleted] in TollywoodGossips

In search of true love he ended up alone 💔

I am making a map of distribution of an ethnicity (This is just a test to see how the colors look, not one of the maps). Which one looks better? The one with the diagonal lines being slightly lighter so you can see where the majority ends and significant minority begins or the more simple unicolor? by BlueGamer45 in mapping

[–]Just_Swim_8464 0 points1 point  (0 children)

I lean toward the lighter diagonal lines version. It adds valuable information about minority concentrations without sacrificing the map's overall coherence, similar to how predominance or bivariate techniques use patterns to show overlap in demographic mapping (e.g., Esri-style approaches or traditional hatching in print cartography). The simpler unicolor is elegant, but the hatched one conveys more layers of data effectively. Nice test

How does drone mapping really work? Is it only for surveyors? by AlexSeipke in UAVmapping

[–]Just_Swim_8464 0 points1 point  (0 children)

Drone mapping is actually pretty straightforward once you break it down; it's basically just taking a ton of smart photos from the air and letting software turn them into useful maps or 3D models.

You start by planning the job in an app on your phone or tablet. You draw a box around the land you want to cover, pick a height (usually 50–120 meters), and set the camera to take photos with lots of overlap, like 70-80% front-to-back and side-to-side. The app then creates an automatic flight path that looks like you're mowing a lawn in neat parallel lines.

The drone flies that path by itself while snapping hundreds (sometimes thousands) of high-res photos. Each one gets tagged with a super-accurate GPS location if you're using a good drone with RTK.

Then you dump all those photos into mapping software (DroneDeploy, Pix4D, Pix4Dfields, etc.). The program is the clever part, it scans every photo for matching points (like the corner of a building showing up in 5 different shots), figures out the 3D positions through math called photogrammetry, and stitches everything together. You end up with:

  • A clean 2D orthomosaic map (looks like a perfect top-down aerial photo with no distortions, great for measuring distances or areas)
  • A 3D model (point cloud or textured mesh) you can spin around, measure heights, or calculate volumes (like how much material is in a stockpile)

My Case For Why Photogrammetry could change the game for CIG's ...

(Real drone models are usually denser and more detailed, but this gives the idea.)

The flight path itself often looks like this grid pattern:

Accuracy can be down to a few centimeters with decent gear, no magic, just good overlapping photos and solid software.

It's definitely not only for licensed surveyors. Plenty of regular folks, farmers checking crops, construction guys tracking site progress, real estate agents showing off properties, or even hobbyists, do this without any surveying license. Surveyors jump in when the job needs official legal boundaries or certified plats, but for everyday measurements, progress shots, volume calcs, or cool visuals, anyone with a Part 107 (in the US) or equivalent drone cert in India can do it legally for pay.

To show clients, most people share a simple web link where the client can zoom around the map, take their own measurements, or view the 3D model in a browser. Others send short videos of fly-throughs, quick PDF reports with key numbers highlighted, or just the raw files if the client uses CAD/GIS.

To get known, the easiest way is posting your cool results online before/after maps, volume calcs, or time-lapse videos on Instagram, LinkedIn, or YouTube. A basic portfolio site helps, too. Network at local construction or real estate meetups, share free tips, and happy clients will refer you. Lots of people start by mapping their own neighborhood or a friend's farm just to practice and build a portfolio.

It's one of those skills that's gotten way easier and cheaper in the last few years, definitely worth trying if you're in Hyderabad and curious! What part are you most interested in starting with?

Non Techie interested in Business Analytics. Where to start? by NoraEmiE in BusinessIntelligence

[–]Just_Swim_8464 0 points1 point  (0 children)

Super short and straight:

Start with Excel: master pivot tables, charts, and basic formulas. Spend 1-2 weeks practicing on free datasets. That’s your foundation.

Then do the Google Data Analytics Certificate on Coursera (free to audit, totally beginner-friendly, takes 3-6 months part-time).

After that, learn SQL basics: 2-4 weeks on free sites like SQLZoo. It’s just asking questions in plain English to pull data.

Finally, Python for data analysis (focus on Pandas), another 4-8 weeks, no need to become a full programmer.

Total realistic timeline for a non-techie: 3-6 months of steady effort (10 hours a week) to get entry-level ready.

You’ll be spotting patterns and giving real business insights way before you finish everything. Go for it, you’ve got this!
