3D Maps:
Practice Makes Perfect

Today, I had to work on a lot of 3D maps using population, population growth, and population density. I think I spent roughly around 6 hours today just working on the 3D maps for my client. Last Saturday was my first time to handle 3D maps and I think I have gained some nice progress in familiarizing myself with the basics.

Here’s my top pick for the day, because the colors I used here are UP’s logo colors. The green ones indicate a positive (increase) growth rate in the population of the barangay. The red ones indicate a negative (decrease) growth rate in the barangay. I guess there are a few pro-RH barangays if based on the data from 2000 to 2010, right? This is NCR data, which is tilted a little to show off its finest angles:

NCR Only

The one thing I enjoyed about making 3D maps with ArcScene 10 is the ability to rotate in various directions:

Later on, I stepped out of the barangay units and proceeded to aggregate the parameters at the municipal or city level, where everything had an upward trend.

When I have recovered my necessary hours of sleep, I will post more about techniques in shadow and light rendering that I have discovered this morning. For now, I leave this visual treat
