Thanks to @BNHRdotXYZ for leading last nights' #Wemap session on @qgis.
It was a fun getting your feet wet on #GIS, and was an excellent overview of what's possible with #QGIS and #OpenData, like #OpenStreetMap
The recording is online: http://youtu.be/295wyYGTODw

DATA
> Relative Wealth Index (https://data.humdata.org/dataset/relative-wealth-index)PROCESS
1. Load the RWI point layer for the Philippines.
2. Style the layer as square markers—size: 2400 meters at scale; color: ramp of your choice.#30DayMapChallenge #30DayMapChallenge2024 #Day8 #HDX #MadeWithQGIS #QGIS #FOSS4G #GISChat #Wealth #Poverty #RelativeWealthIndex #Meta

30 DAY MAP CHALLENGE 2024 | DAY 8 - DATA:HDX
Relative Wealth Index
The Relative Wealth Index (RWI) from Meta are microestimates showing the relative wealth and poverty of different areas in a country.
IMPORTANT: As with any global-scale, machine-learning product, you should first validate the usefulness and applicability to your local context.

First #FOSS4GPH 2024 meetup in the books! Maraming salamat sa mga dumalo at nakibahagi!
We will (hopefully) be doing this every 3rd/4th Thursday of the month for the rest of the year so we hope to meet more FOSS4G enthusiasts at future events!

According to the authors of the paper published in iScience [4]: "With further improvements in stability of local clocks used for timing, it is anticipated that MuWNS can be adapted to improve autonomous mobile robot navigation and positioning as well as other underground and underwater practical applications."
In what other ways do you think this technology can be used? Deep-sea mission navigation perhaps?
-
Muons have been used previously to image archeological structures, search for hidden Mayan ruins, and detect hidden corridors and chambers of the Great Pyramid of Giza [3].
Recently, the first navigation with wireless muometric navigation system (MuWNS) in indoor and underground environments was successfully tested [4] showing accuracy exceeding the GPS single-point positioning.
-
You know GPS but have you heard of muPS (Muometric Positioning System)?
The muometric positioning or navigation system (muPS/μPS/muNS) is a novel positioning/navigation system that utilizes the ubiquitous and highly-penetratve cosmic-ray muons [1][2].
This technique does not require active signal generation [1][2] and is usable in environments where GPS/GNSS signals cannot reach such as underwater and underground.

Regardless of whether the threat of .zip (or .mov) domains are overblown, it doesn't hurt to be careful and remain vigilant when opening links (whether they have .zip or not at the end).
-
There have been some examples online of people registering .zip domains—some as a joke—to show how these can be used by malicious actors. While there are those who argue that these concerns are unwarranted and overblown, others believe that the general availability of .zip (and .mov) TLDs introduce additional risks our already precarious online environment—especially considering that not everyone might be aware of these risks.

3a. For the first visualization:
- Apply a graduated symbology or "data-defined" symbology using the pop_sum field.3b. For the second visualization:
- Use geometry generators and the "scale" expression with pop_sum and max(pop_sum) to create the bar/column graph.🧵 4/4

1. Used QGIS' "Create grid" algorithm to generate a grid of 30 second (or longitudes) covering the extent of the Philippines.
2. Used the "Zonal Statistics" algorithm to compute for the sum of population (pop_sum) for each latitude (or longitude) using the WorldPop population data.

The data used are a population raster (30 second/1km grid) from WorldPop and Philippine admin boundary map from GADM.
The first map visualizes the population per 30 second of latitude (or longitude) using color while the second visualizes the population as a bar/column chart.
The process was once again fairly straightforward.

Friday is map day! Were you waiting for new maps/visualizations of Philippine population? Well, you're in luck because here's #anotherone (or four really).
This time they are maps of population per latitude (and longitude) in the Philippines. As usual, all the processing and map-making was done in QGIS.

- Ran the process dividing the country in 2 to 8 groups.
What do you think?
Note: I included the population of Highly Urbanized Cities and Component Cities in the population of the province/area that they are geographically located in (e.g. Basilan's population includes that of the city of Isabela).
Data from PSA 2020 Census and GADM. Processed in QGIS.

- Made a population layer (based on 2020 Census) composed of provinces and NCR cities/municipality.
- Used QGIS' "Order by expression" algorithm to sort the layer features based on their centroid latitude (x(centroid($geometry)).
- Made a script that would divide the sorted features into groups whose population sum was approximately the same (or close to it).

Have you ever wondered what the Philippines would look like if we divided it into areas of equal population? Nope? Only me? Oh well here it is. 😅
The process was fairly straightforward.

Sharing the highlights of Pista ng Mapa and State of the Map Asia Conference 2022.
A big thank you to everyone who helped and participated to make this the biggest celebration of open mapping and open geospatial in the the Philippines and in the Asian region!
