The Art of Maps

Posted by Tuan Ifan Vpy on 29 June 2014 in English (English)

Map is an Art. I didn't know that until I finished mapping all details in Zone A, Phú Mỹ Hưng New City Area, in the Saigon South New Urban area of Ho Chi Minh City.

What fascinates me was the colourful rendering of various areas and items, such as residential zones, schools, rivers and parks. Well, after slow mapping for 2 years and intensive work for 3 days by everyone and me, it turns out to be a piece of art.

Btw, I also draw administrative boundaries to the subdivisions of the Zone A - Phu My Hung. This sounds weird because they are NOT administrative, but they do help proper addresses to render. Further, zone boundaries make it more convenient for users when searching for them in the search box.

Now I know that OPENmapping is not about drawing roads. It brings everything.

Lalor station on South Morang Line

Posted by Tuan Ifan Vpy on 5 July 2013 in English (English)

I took a long train to Lalor for a friend's birthday party. On the way back, I had to wait for 30 mins for the train towards the City, so I looked around the area.

To be said, Lalor is a small station, unstaffed 24/7. It has two platforms in an island format. The main building is made of brick, which hosts a shelter inside. Access to the station is made via a pathway branching from the footpath across the railway line.

I tried to add the lines immediately, however, Go Map!! app has some errors with uploading changes (the app quits when uploading), so I would map it later at home.

Besides the station, I changed many railway tags which show 'Epping Line' to 'South Morang Line'. There fore, the shared rail tracks previously tagged with 'Epping / Hurstbridge line' were changed to 'South Morang / Hurstbridge line'.

  • Got my first group mapping trip with another OSM mapper. We'll go to Burwood East Reserve between 2PM and 4PM this Sunday to map some roads and features around. As this is my first trip so I don't really know what should be done in such a trip. If you wanna join us or wish to discuss about this activity, contact me via the OSM inbox messaging, or send me an SMS (My phone number can be found in my profile).

Mapping @Armadale, VIC, 28/6/2013

Posted by Tuan Ifan Vpy on 27 June 2013 in English (English)

Today I surveyed the area around Armadale railway station, VIC, Australia. This includes :

1. Adding POIs :

I went to Armadale station at around 3:30PM, and exited at Platform 4. Then I found that the roads running along the train line did not exist ~ this would be done later.

Then I walked through the Kings Way, and added the shopps around it. After visiting the Arcade, I entered High Street, and walked east towards Cheel Street. Then I followed Cheel St back to the station.

During the journey I added around 20 POIs, most of which are interior designs and furniture shops, which are supported by Pushpin, but still not yet available in OSM page.

Due to the limit of time (I woke up late), the whole area was still not mapped yet. I'll come back here in a couple of months.

2. Editing roads

Back at home around 10pm, I added two roads (Cheel St and Morey St), plus Kings Way and the Kings Arcade.

A parking lot, probably for commuters', was drawn as well. As Armadale is one of 3 low-passenger stations between Richmond and Malvern, there are not many spaces in the lot.

3. Editing the train station

The plain lines depicting the 4 platforms were removed, and replaced by areas of the same type instead, and layered with -1 value.

The buildings were drawn as two seperate ones for the building. In addition, the smaller buildings on platforms 1 and 4 were drawn as well.

The footpath crossing the main building was drawn as a bridge, because of the fact that it lies above the platforms.

*** NEXT Survey : ***

Surrey Hills, VIC + Time : TBC + Add POIs for the commercial area along Union Road and Canterbury Road.

You're welcomed to JOIN me and be my co-surveyor, esp. at weekends (Sat & Sun). Just let me know via SMS or message.


My mapping projects

Posted by Tuan Ifan Vpy on 20 June 2013 in English (English)

1. Vũng Tàu, Vietnam

Vũng Tàu is a district-level city of Bà Rịa-Vũng Tàu province, Vietnam. The city centre is about 125 km away from Ho Chi Minh City. Population is estimated at 300,000 - 400,000 people as of 2013.

Works to be done :

  • - Adding roads, sub-roads & lanes (called 'hẻm' in Vietnam) ~~ in process
  • - Adding services : shops, supermarkets, marketplaces, parks, restaurants... ~ lacking information
  • - Editing natural features : adding forests, streams, editing coastlines and rivers based on provided Bing aerial imagery.
  • - Editing localities : draw borders of wards (known as 'phường' in Vietnam) ~ based on Vietnamese-origined official maps.

2. Melbourne, VIC, Australia

OSM map for Melbourne shows that many suburbs lack information about services, such as shops, restaurants, banks.

E.g. Footscray, Glenhuntly, Ormond.

Works to be done :

  • - Surveying places at free time, usually at weekend.
  • - Adding services by a mobile app. Currently i'm using Pushpin.
  • - One POI should include : name of service, operating hours, addresses, type of product (i..e cuisine), telephone numbers.

--> This project can be done in group work. Each person takes charge of one section of the area.

3. Melbourne, VIC, Australia

Adding utilities for some public places.

* The University of Melbourne - Parkville campus

  • - Utilities : Water fountains, recycling bins, fire hyrants, benches, emergency phones, toilets.
  • - Roads : editing some paths, adding more paths to lawn and orchard areas.. Adding steps leading to building entrances.
  • - Natural features : adding trees (especially those serving memorial purposes), forests (for a group of trees), and orchards.

* Monash University - Caulfield Campus

Same as above.

Hi guys,

I've joined OSM several months ago and made hundreds of edits but I've made no diary here... Hmm.. let's say... in this very first note, i'll tell somehthing about me and my mapping hobby.

I was born in a seaside town called Vũng Tàu, which is about 125km southeast of Ho Chi Minh City (a.k.a Sài Gòn). Life was peaceful until 2008 when I came to Sai Gon for college and work. . Hmm Saigon, frankly speaking, is a messy city, and even though it's a fast developing urban area in Southeast Asia, infrastructure are not really fit with the trend.. however, thanks to 'smart' anti-automobile policy of the govt, we don't really have serious traffic jams similar to nearby metropolitans like Bangkok or Jakarta. Most of us, well, around 80% or more, ride motorbikes to work and school everyday. And despite its inconveniences (distance, speed, weather conditions...), it brings more leisure on the road.

I like maps and geography since I learned how to read and write. Hmm,... when I was 7 or 8, I visited my neighbour, and suddenly got interested in a globe in his living room. I then asked him to see the globe and couldn't really kept my eyes out of it for 3 hours. Coming back home I told my Dad to buy a world map, and since then I started to look at it every day. Hmm, it was really unusual for a kid at primary school age who didn't like to go out for play sports or music~~, but he chose maps instead.

I developed mapping hobby when Google launched 'Mapmaker' project. At first I was really keen on contirbuting for the project, but then I discovered that Google Mapmaker was not smart enough.

  • Community approval policy : Every edit needs approval from others in a voting system. This is a time consuming process, especially when there are not enough votes for your contributions.

  • Lack of respect of differences : Some contributions which are out of concern of others, including supervisors can be turned down. Well, I spent two hours adding several paths in parks and a museum (Reunification Palace) in HCMC, and submitted them. The only answer I received was that 'pathways are good but they are UNNECESSARY, because our Maps features should focus on roads and the use of GPS when traveling'. I told them that even though it seemed cars don't use it, but 'pathway' can help describe the ways for walkers or visitors.

Moreover, 'pathway' is available in the toolbox, and we should make use of it . I then pointed examples of parks and university campuses elsewhere in the world, such as Georgetown University in Washington, D.C and riverside parks in Singapore. What I received was that 'Well, they are different cities, and we're in Vietnam, and we're different'.

Well, then I said goodbye to them because I felt that those conservative mapmakers do not respect me and my and turned to OSM a few months later.
