Users' Diaries

Recent diary entries

I mentioned in my previous post about why it’s great to meet up with other mappers. One thing that someone suggested I write a diary about is the method I found to be notified about map-worthy changes to one’s local area. It turns out that not everyone has heard of the London Gazette, its role in local law and administrative changes in the UK, and the online services it offers to help discover the changes.

So here’s the Wikipedia page for the Gazette And here’s the website

The core of the publication is the notices. The rules of the road network for residential and even some of the more major roads in an area (pretty much everything that doesn’t constitute the trunk road network) are delegated to local authorities, and the ritual incantation they have to go through to change those rules is to publish notices in the local press and in the London (or Edinburgh or Belfast) Gazette.

In the navigation bar at the top of the page is a Notices menu, which will list all the most recent notices in the UK.

There are filters on the left hand side of this page where you can search for and filter the list to the particular notice type and area you’re interested in. For my local area, for things I might want to add to OSM, I’ve found that the following customisations work best:

  • restricting the list to Notice Code 1501

  • filtering the location by Local Authority from the drop-down box (in my case, the London Borough of Ealing)

  • Hitting the “Update results” button and then changing the sort order to “Latest”.

I attended my second OpenStreetMap London social today. They happen approximately once every two months, but it’s been a year since my first one. It’s daunting, going to a pub in central London to meet a group of strangers, especially if you’re not the most outgoing person and your expectations are that they won’t be either. So I just wanted to recommend it. When you have a niche interest such as mapping the world for no particular return other than the vague idea that this stuff is really important and will change the world, it’s great to meet a few other people who feel the same way. Whether it consumes all your free time, or is just something you spend 15 minutes doing when you visit a new place, it’s brilliant to get perspectives from other mappers, to hear what motivates others, to see what they are doing with the data you contribute, and get some tips on things you might not have heard about. I can’t remember where I heard about the London meetup, but reminders are usually posted to the talk-gb mailing list, to the weeklyOSM newsletter, and to the OSMCal website, so do check those places out for updates.

I want to share that I received the “State of the Map Asia 2023 Community Champion Awards” on November 17 as recognition for advocating the use of OpenStreetMap and community-building across different groups and regions in the Asia-Pacific region and promoting diversity, equity, and inclusivity within the community.

As a student leader passionate about exploring not just maps, but also the diverse tapestry of communities in the Asia-Pacific, I recognize that my efforts are a work in progress. I aim to continue advocating for OpenStreetMap’s advancement and I am deeply grateful to the State of the Map Asia team, my colleagues, mentors, family, friends, and everyone who has contributed to this remarkable journey.

It is one year since I was elected to OSMF board.

I am recording time spend on some things, including time spend on things resulting from being on OSMF board.

So I can report that since 2022-12-09 it was 355 hours.

It records time spend on what I do as result of being on OSMF board. So it excludes for example time spend on mapping and StreetComplete development. And it includes time on some things that I could complete without being on OSMF board like some attribution-related activities - that I do as result of being on OSMF board.

I feel like I owe the world this, I owe Zimbabwe this, we can’t step into the new year before I share this news with everyone. It was June of this year when I was voted as a New Voting Member. I am grateful for a supportive nominator Kingsley Chika CHUKWU and the HOT family as a whole. I might be the first Voting Member from Zimbabwe and for this I was compelled to share this step with the rest of this family especially.

Getting to be a Voting Member came with proving your worth and making sound suggestions and decisions I am already incorporating or taking part in. I am happy to be recognized to this extent and I promise to stand in for the community, to the community as we build a stronger community. You can read my responses here:

Так ребята, всем привет, особенно тем, кого давно не видел. ;)

Сделал наконец то, что собирался сделать уже года два: генерализованную карту “покрытий”, они же land covers, на основе данных OSM.

В русском географическом языке, кажется, такого слова нет, ближе всего подходит наверно “тип ландшафта” или “доминирующий тип растительности”: то, что покрывает землю и определяет, как то или иное место видно сверху. В основном это растительность: леса, кустарники, степи, поля, луга, но если растительности нет, то то, что есть: городская застройка, пески, голые камни, пляжи.

Как оно считается: поскольку последовательной классификации land covers в osm нет, то берутся все landuse=* и natural=*, и сопоставляются с гексагональной сеткой (h3). Для каждого гекса определяется тег, полигоны с которым в данном месте занимает наибольшую площадь, и таким образом этот тег является наиболее характерным.

My experience at Pista ng Mapa 2023, from November 21-23, was an exhilarating adventure as eleven Viscan YouthMappers (VYM) and I delved into a three-day conference at the University of the Philippines Tacloban College. The event seamlessly blended intellectual engagement, skill-building workshops, and a celebration of our dedication to open mapping.

The Summit Hotel in Tacloban City hosted the kick-off, featuring plenary sessions with insightful presentations by Mr. Mikko Tamura of Open Mapping Hub – Asia Pacific and Dr. Alfredo Mahar Francisco Lagmay of UP Resilience Institute. The day concluded with parallel sessions, providing a diverse look into mapping’s facets. The highlight of my Day 1 was presenting our VYM project, ‘Mapping of Fire Hydrants as Baseline Data for Fire Emergency Response in Leyte Province, Philippines.’ This was very memorable for me as this transitioned me from a participant last year at PNM2022 to a speaker this year.

Day 2 immersed us in hands-on workshops led by industry experts, from Geoladies’ Ms. Leigh Lunas’ “When Women Maps” to Action for Economic Reform’s Mr. Mark Aimon Pangan’s insights on Digital Data Collection to BNHR’s Mr. Ben Hur Pintor sharing knowledge about beyond shapefiles and file-based data management and “Getting started with Developing Geospatial Applications” by Mr. Luiz Caezar Ian Panganiban of Ausome Maps. These sessions not only enhanced my mapping skills but also fueled my inspiration for geospatial applications.

Day 3 centered on community connections, with meet-ups led by Mr. Mikko Tamura for the OSM Philippines, Mr. Ben Hur Pintor for the OSGeo, and Ms. Feye Andal for the YouthMappers. The YouthMappers Meet-up allowed us in Viscan Youthmappers to reflect on our achievements, identify challenges, and envision our future aspirations. Moreover, the afternoon featured an immersive field trip through Tacloban City and Palo, Leyte, connecting us with local culture and history.

据国家安全部,当前,随着新一代信息技术加快发展,地理信息数据与数字经济的协同效应不断增强,为经济社会发展提供了可靠的数据要素保障。地理信息数据既是重要的战略性数据资源,又是新型生产要素,可广泛应用于精准农业、能源电力、智能网联汽车等行业领域及我们日常快递网购、外卖送餐、家政服务等生活场景。但一些别有用心的组织和人员,却利用地理信息系统软件,企图窃取涉密敏感地理信息数据,对我国家安全带来了威胁和隐患。

伸向地理信息数据的黑手

地理信息系统软件是具备地理信息数据采集、存储、分析、管理、共享等功能的专业软件。这些软件功能强大,能够将采集的各类地理信息标注在地图上,并根据需要进行分析和展示,坐标精度甚至能够达到厘米级。

然而,个别境外组织、机构和人员却盯上了地理信息数据这块“大蛋糕”,企图利用地理信息系统软件开展情报窃密活动。手段包括:在软件使用过程中自动连接境外服务器,无限制收集用户数据;蓄意在软件中预置“后门”,为网络攻击和数据窃取打开方便之门等。

另外,少部分用户的数据安全意识薄弱,将城市管网、军事目标、涉密单位的高精度地理位置坐标标注在地图上,产生严重失泄密风险隐患,可能会造成无法挽回的损失。

专项排查整治斩断黑手

地理信息数据属于高价值情报,是境外间谍情报机关情报窃密的重点。通过窃取我国高精度地理信息数据,可还原出我交通、能源、军事等重要领域特定区域的三维地貌图,为侦察监视、军事行动提供关键支持,将严重威胁我军事安全。

近期,国家安全机关工作发现,我国有关重要行业领域使用的境外地理信息系统软件存在搜集外传地理信息数据的情况,部分数据重要敏感,甚至涉及国家秘密,对我国家安全构成严重威胁。

针对上述情况,国家安全机关会同有关部门开展地理信息数据安全风险专项排查治理,指导、协助涉事单位开展清查整改,及时消除重大数据窃密、泄密等安全隐患。
