A trip to Wisley and I noticed that the new Clear Lake was not mapped at all. I only managed to walk around one side so it could do with some adjustment I’m sure. The Glass House Border has been re-landscaped into The Oudolf Landscape with new paths - I didn’t get the chance to map these, but hopefully someone will in the future.

Esse texto é uma sugestão de etiquetagem da vegetação natural brasileira como classificada pelo Instituto Brasileiro de Geografia e Estatística (IBGE) em seu Manual Técnico da Vegetação Brasileira. É uma expansão e atualização do meu diário anterior em que proponho uma forma de mapeamento da Caatinga. O intuito é ser um suporte para quem tiver interesse em mapear áreas vegetadas no OpenStreetMap sem a necessidade de criação de novas tags e utilizando o que já está documentado na Wiki. Já esclareço de início que as tags disponíveis no OSM são muito limitantes para o mapeamento ambiental e, portanto, algumas liberdades foram tomadas. Além disso, o sistema de etiquetagem não pode ser muito complexo porque pode desmotivar o mapeamento por mapeadores iniciantes.

🌴 Sugestão de classificação da vegetação quanto ao porte (altura) 🌴

Para essa proposta, adaptei o que está descrito na Wiki acerca de Vegetação e vejo que quatro valores da tag natural ordenados em grau de porte (altura) seriam úteis. Resumidamente, os valores em ordem decrescente de porte são:

natural=wood > natural=scrub > natural=heath, natural=grassland.

🌳 Etiqueta natural=wood

Nesta sugestão, wood trata-se de uma vegetação “florestal”, densamente “arborizada” com árvores muito altas como presentes em fisionomias da Floresta Amazônica e Mata Atlântica. É o que temos no imaginário popular do que seria uma “floresta” ou “bosque”. Na classificação do IBGE, correspondem às Florestas Ombrófilas, Estacionais, Savanas Florestadas, Savanas Estépicas Florestadas e Restingas Arbóreas. Eu preciso destacar aqui que essa definição varia conforme o Bioma. Então, uma vegetação amazônica marcada com a etiqueta natural=wood não tem o mesmo porte que uma vegetação do Cerrado e Caatinga marcada com a mesma etiqueta. Porém, nestes biomas a vegetação mapeada apresenta um porte característico que mais se aproxima de uma “floresta densamente arborizada”. Algumas imagens a seguir do que poderia ser etiquetado dessa forma segundo essa minha proposta.

Floresta de árvores com copas altas e densas Floresta Ombrófila Densa da Amazônia, Bolívia. Link.

Floresta de árvores araucárias com copas altas Mata de Araucárias no Parna Aparados da Serra (divisa dos estados de Rio Grande do Sul e Santa Catarina). Link.

Visão do alto de uma floresta de árvores muito verdes Parque Estadual Morro do Diabo em Teodoro Sampaio - SP. Link.

Visão de uma floresta densa Cerradão (Savana Florestada) no Parna Serra da Canastra - MG. Link.

🌵 Etiqueta natural=scrub

Seguindo na classificação, temos a tag natural=scrub que é descrita na Wiki como “matagal”. É uma etiqueta cheia de controvérsias e aqui eu proponho que seja utilizada para a vegetação que tem o porte menor do que uma “floresta”. Neste sentido, há o predomínio de arbustos e árvores medianas que não alcançam os 20-30 metros frequentes nas Florestas Ombrófilas, por exemplo. Além disso, as copas das árvores não são tão densas. Inclusive, um dos critérios descritos na Wiki (aqui) para diferenciar natural=wood de natural=scrub é que a vegetação de scrub não fica sob uma copa de árvores que impede que arbustos e árvores menores recebam luz solar. É a vegetação mais frequentemente encontrada na Caatinga, Cerrado e Pantanal. Abaixo alguns exemplos:

Matagal com árvores baixas, esparsas e arbustos Campinarana Arbustiva em Mâncio Lima, Acre. Link.

Matagal com árvores baixas, esparsas e muitos arbustos secos Savana-estépica Arborizada (período seco) na ESEC Seridó, Rio Grande do Norte. Link.

Matagal com árvores baixas, esparsas e muitos arbustos secos Restinga Arbustiva na Ilha do Cardoso, São Paulo. Link.

🌿 Etiquetas natural=heath e natural=grassland

As duas últimas etiquetas representam o menor porte da vegetação, ou seja, herbáceas, gramíneas e outras plantas que não chegam a formar um dossel mediano como um matagal.

heath trata-se de um valor bastante confuso. A Wiki define natural=heath como um “urzal” ou “charneca”. Um local com vegetação arbustiva e lenhosa muito pequena. Ela recomenda utilizar essa etiqueta para qualquer ecossistema semelhante as fotos sugeridas na página. Particularmente, achei nada claro. Há também uma barreira regional nisto tudo, visto que charneca e urzal são utilizados para locais predominantemente áridos e pedregosos no exterior, mas no Brasil ganharam significados opostos, representando áreas com características pantanosas. Sendo assim, eu tomei como liberdade utilizá-la para classificar a vegetação rala em que predomina essencialmente arbustos e herbáceas raquíticas, sem considerar a presença de umidade. Esta classificação também pode apresentar uma fração arbórea mas as árvores se apresentam muito espaçadas uma das outras e geralmente são de apenas uma espécie. Como exemplo, as Savanas-Estépicas Parque no Parque de Espinilho, RS, os Parques de Carandás nos Pantanais Mato-grossenses e algumas formações como parque de palmeiras na Região Nordeste. A Restinga Herbácea e o “campo sujo” no Pampa também podem adquirir esse valor.

Matagal com árvores baixas, esparsas e muitos arbustos secos Restinga Herbácea. Link.

Matagal com árvores baixas, esparsas e muitos arbustos secos Savana-Estépica Parque no Parque Estadual do Espinilho, RS. Link.

Matagal com árvores baixas, esparsas e muitos arbustos secos Campo sujo (Estepe parque) no Rio Grande do Sul. Link.

Matagal com árvores baixas, esparsas e muitos arbustos secos Savana-Estépica Parque (período seco) no Parque Estadual do Seridó - RN. Link.

Por fim, a etiqueta natural=grassland possui o mesmo porte que natural=heath em relação à vegetação. A diferença é que natural=grassland já não apresenta espécies arbustivas lenhosas, mas sim há o predomínio de gramíneas. Equivale ao “campo limpo” dos campos do Pampa no Rio Grande do Sul (Estepe Gramíneo-Lenhosa) e à Savana-Estépica Gramíneo-Lenhosa ou “campo espinhoso” em outras regiões.

Matagal com árvores baixas, esparsas e muitos arbustos secos Campo limpo Estepe Gramíneo-Lenhosa (sem componentes lenhosos) em Aceguá - RS. Link.

🍃 Outras etiquetas para caracterização: leaf_type e leaf_cycle 🍂

A etiqueta leaf_type é utilizada para descrever o tipo de folhas encontrada na maioria das plantas no caso de uma vegetação. Pode assumir os valores broadleaved para angiospermas, o valor mais típico para os biomas brasileiros, needleleaved para plantas com folhas no formato de “agulha” como pinheiros, mixed para vegetação com os dois tipos presentes e leafless para a vegetação sem folhas como cactáceas, por exemplo. Expandindo um pouco mais o significado, decidi considerar broadleaved para plantas angiospermas e needleleaved para gimnospermas. Assim, conforme o Manual Técnico da Vegetação Brasileira do IBGE, no Brasil apenas a Mata de Araucárias (Floresta Ombrófila Mista) possui o valor needleaved. É importante frisar que esses valores valem para a vegetação originária com a etiqueta natural porque uma floresta de pinheiros utilizada para extração de madeira, por exemplo, recebe a etiquetagem landuse=forest + leaf_type=needleleaved. Além disso, não recomendo a utilização de leaf_type=leafless para vegetação presente no semiárido nordestino (caatingas) porque a presença ou não de folhas depende da estação e existe uma etiqueta para isso (descrita a seguir). Só recomendo caso o mapeador possua conhecimento suficiente para determinar que a maior parte da vegetação é constituída de cactáceas, bromélias espinhosas ou outras espécies sem folhas durante todas as estações.

leaf_cycle é outra etiqueta adicional que complementa a vegetação mapeada. Ela se refere ao ciclo das folhas ao longo das estações. Assume os valores evergreen para folhas que sempre permanecem verdes e não caem com o passar das estações, semideciduous para plantas que perdem suas folhas por um período curto de tempo, semi_evergreen aparenta possuir o mesmo significado que a anterior, deciduous para plantas que perdem suas folhagens totalmente durante um determinado período do ano e mixed para a ocorrência de ambos os casos. Neste sentido, as etiquetas que mais confundem são semideciduous e deciduous (ignorando semi_evergreen pois até o link do significado na Wiki redireciona para o significado de semi_deciduous). Assim, para diferenciar ambas, decidi usar a própria diferenciação do IBGE que considera semidecidual a vegetação em que a porcentagem de plantas que perdem suas folhas não ultrapassa os 50% em relação a vegetação inteira.

🍀 Etiquetas delimitadoras description e description:source 🍀

Enfim, nada impede que se adicione etiquetas bem mais específicas quando possível. Na etiqueta description pode-se usar o valor com o nome exato do Sistema Fisionômico (ex: description=Savana-Estépica Gramíneo-Lenhosa) e informar a origem desse termo na descrição. No caso do Sistema Fisionômico apresentado neste texto é o próprio IBGE, source:description=IBGE. Talvez até um ref:IBGE com o valor atribuído pelo instituto na sua própria legenda de classificação seja útil para ferramentas de busca (ex: utilizar ref:IBGE=D para Floresta Ombrófila Densa, ref:IBGE=Ta para Savana-Estépica Arborizada e assim por diante).

Com base nisso tudo, é possível gerar a seguinte tabela:

CNEFE: IBGE antecipa microdados de cadastro de endereços para auxiliar gestores do Rio Grande do Sul

CNEFE: IBGE antecipa microdados de cadastro de endereços para auxiliar gestores do Rio Grande do Sul O IBGE divulgou, nesta terça (21), de maneira antecipada, os microdados do Cadastro Nacional de Endereços para Fins Estatísticos (CNEFE). A medida é mais um esforço do Instituto para disponibilizar, com a maior celeridade possível, informações que possam auxiliar a situação de calamidade enfrentada pelo Rio Grande do Sul. A divulgação completa será no dia 14 de junho.

Em fevereiro, o IBGE já havia divulgado as Coordenadas Geográficas das Espécies de Endereços do Censo Demográfico 2022. A novidade desta divulgação é a informação dos atributos completos de endereçamento dos mais de 106 milhões de endereços coletados, de acordo com o padrão utilizado pelo IBGE, incluindo logradouro, número e modificador, complemento, localidade, CEP, espécie da unidade visitada, tipo de edificação, nomes dos estabelecimentos, entre outros. Também foi disponibilizado o dicionário de dados com a caracterização do conteúdo e um documento com orientações de uso por conta dessa antecipação.

O CNEFE é constituído com dados do país inteiro, mas a ideia de antecipar a divulgação em algumas semanas é oferecer uma grande fonte de informações para enriquecer e incrementar o trabalho dos gestores, técnicos e profissionais que estão atuando no Rio Grande do Sul.

A diretora de pesquisas do IBGE, Elizabeth Belo Hypolito, destaca o empenho de todo o Instituto no suporte aos governos Federal, Estadual e municipais “O IBGE tem se reunido constantemente para discutir ações que possam auxiliar no trabalho no Rio Grande do Sul. As diretorias e a Superintendência Estadual estão fazendo um esforço conjunto. E essa antecipação dos microdados do CNEFE foi uma das medidas que conseguimos viabilizar”, reforça.

Para a diretora de Geociências, Ivone Lopes Batista, “a divulgação dos endereços coletados no Censo Demográficos 2022 permitirá o georreferenciamento de cadastros oficias que possibilitam a identificação, por exemplo, de populações vulneráveis, e auxiliam no apoio a reconstrução das áreas afetadas no Rio Grande do Sul”.

Eduardo Baptista, gerente do cadastro, ressalta a importância da divulgação dos microdados. “Será possível fazer uma análise ampla sobre os endereços atingidos, visando atender à sociedade na prestação de apoio às pessoas atingidas e no planejamento de restauração dos locais que precisarão ser reconstruídos”, afirma.

As informações poderão ser consultadas em arquivos de tabela ou plataformas de exploração de manipulação de dados geográficos. “Além da análise dos dados do próprio CNEFE, o usuário poderá cruzar os dados com outras bases existentes em instituições públicas e privadas, como cadastros de bairros e localidades atingidas oriundos das prefeituras e do Governo do Estado”, exemplifica Baptista.

A divulgação completa do CNEFE será no dia 14 de junho, quando serão disponibilizados os materiais complementares com notas metodológicas e arquivos com dados do CNEFE agregados por CEP. Os dados poderão ser baixados ou explorados através das plataformas de visualização de dados do IBGE - no hotsite do Censo Demográfico 2022 e na Plataforma Geográfica Interativa (PGI).

Em casos de dúvidas, o atendimento por telefone (0800 721 8181) está disponível, bem como o Fale Conosco e demais canais encontrados na área de Atendimento do site do IBGE, que pode ser acessado clicando aqui.

The NCST, in it’s current configuration, extends from a quasi center point of Wilcox Junction east to Trenton FL, west to Cross City FL, and south to Chiefland FL. All three of those terminal points have expansion plans when funding becomes available: Trenton east to Newberry FL (which connects it to Gainesville), Cross City northwest to Perry FL (and then probably on to Madison), Chiefland southeast to Dunellon FL (and the various trails currently operating in/around Citrus county).

While the trail itself is documented and mapped, there are many undocumented access points. Those access points lead to local small streets, residences, and often to local businesses. I am attempting to document those access points, so that bike riders (such as myself) can find safer ways to travel to those businesses.

The Florida Department of Transportation is working on road upgrades in my local area. Those upgrades (State Road 26 and US Highway 19/98) will include paved shoulders outside the travel lane marker line. Those shoulders allow for use by vehicles with breakdowns and for bicycles (although such use should be considered carefully in light of the speed of vehicles on the highway).

The order is not important. (DUBIOUS : DISCUSS)

It is important to use existing values when possible to assist third party tools. However, other values may be used if they are meaningful. For example, if a restaurant specializes in a local dish, it is appropriate to tag that even if the tag does not have widespread global use.

Values should be all lower case, even when listing ethnicities or other proper nouns which would usually have the first letter capitalized. Values are usually singular (cuisine=burger not cuisine=burgers).

Notes
  1. All the quoted passages are taken directly from the OSM Wiki.
  2. All the examples above are taken from taginfo, sorted largest to smallest, with a minimum occurrence threshold of 602.
  3. Why 602 you ask? No particular reason at all. I just gave up summarizing everything from taginfo around that number.

Maps are invaluable tools that serve a multitude of purposes across various aspects of life. At their core, maps provide spatial context, allowing individuals and organizations to understand the geography of an area and make informed decisions. They are crucial for navigation, helping people and goods move efficiently from one place to another by providing clear and precise routes. This is vital not only for everyday travel but also for logistics and supply chain management, where accurate mapping can significantly reduce costs and improve delivery times.

Beyond navigation, maps are essential for planning and development. Urban planners, architects, and engineers rely on maps to design cities, infrastructure, and buildings. They help identify the best locations for new developments, assess the environmental impact of projects, and plan for future growth in a sustainable manner. Maps also play a crucial role in public health by identifying disease hotspots, tracking the spread of epidemics, and planning healthcare services. In agriculture, maps are used to monitor crop health, manage resources, and improve yields through precision farming techniques.

Maps are also powerful tools for communication and education. They can convey complex information in a visual and easily understandable format, making them invaluable for teaching geography, history, and science. Maps help in visualizing data trends, such as population growth, economic activity, and environmental changes, enabling policymakers and researchers to analyze and address various issues effectively. Furthermore, maps promote transparency and accountability in governance by providing citizens with accessible information about their communities and the broader world. Overall, the value of a map extends far beyond its basic function of showing locations; it is a fundamental resource for decision-making, planning, and understanding our world.

But, What If You Don’t Have Access To A Map?

How often do you use maps each day? Perhaps, like me, you use them in getting to and from work each day (you know how to get there, but still like to know traffic updates, duration and so forth), facebook marketplace locations, checking the status of your Amazon packages, or finding new restaurants to try, or fun things to do near you.

What about more serious situations - the closest hospital, emergency room or police station, the local evacuation route, or even navigating through unfamiliar neighborhoods during a natural disaster.

Maps are indispensable tools in our daily lives, guiding us through both mundane tasks and critical situations, ensuring we reach our destinations safely and efficiently while providing vital information for decision-making in times of need.

Lack of access to accurate and up-to-date maps in developing or undeveloped countries has far-reaching implications across various sectors. Firstly, in emergency response scenarios, the absence of reliable maps poses significant challenges. This hampers the effectiveness of rescue operations in disaster-prone regions, hindering timely assistance to affected populations due to the lack of clear routes and local geography knowledge. Consequently, lives are at stake as emergency teams struggle to navigate through affected areas, exacerbating the impact of natural disasters.

Moreover, the absence of accurate maps impedes development planning efforts. Urban planning and infrastructure development become inefficient without detailed geographic information, leading to suboptimal public services such as inadequate water supply, electricity, and transportation networks. Additionally, healthcare delivery is compromised as health workers face difficulties in tracking disease outbreaks, managing vaccination campaigns, and planning healthcare facility construction in remote areas, ultimately resulting in unequal access to healthcare services and inefficient resource allocation.

However, initiatives like HOT are instrumental in addressing these challenges. By promoting open geographic data and community-based mapping projects, HOT enhances the resilience and development of communities lacking access to reliable maps. These efforts not only facilitate emergency response and development planning but also support environmental management, economic growth, education, and legal clarity, thereby fostering sustainable development in regions with limited mapping resources.

Wir sind in Bewegung auf der Suche nach Orten wo wir Musik hören, tanzen, Internet nutzen, Panorama Sicht geniessen und Leute anziehen, die in Freiheit mit Anstand zu Mensch, Tier und Natur leben können und wollen.

Wir haben Regeln, zum Schutz unserer Gesundheit, der Umwelt, unseres Wohlbefindens. Wer ohne Regeln leben möchte ist bei uns am falschen Platz. (wie können hier Fotos hinzugefügt werden ?)

Notes UI Gets a Fresh Look

The most noticeable change this week is a refreshed user interface for notes. It’s now more in line with how changeset discussions look, making the whole platform feel smoother and easier to navigate. Future work will include a discussion pagination support.

And here’s how it looks for those who aren’t registered:

A quick rundown of what’s changed:

  • Note discussions subscriptions
  • New social component with profile pics
  • Color-coded badges for resolved/unresolved notes

Notes Layer Loads Way Faster

This week I’ve been optimizing the notes layer to make it snappier. The new protocol uses about 6-8x less memory, and is more lightweight on both user devices and the server. It’s all about sending only the bare minimum data needed for the notes layer to show up, and it’s built on the recently introduced new web rendering engine.

Here’s a peek at the data format:

The location link has a slightly new look that fits in better with its surroundings.

Feature Icons + Taginfo Integration

One of the more interesting things this week is the new taginfo integration. Feature icons now utilize tagging popularity information. This will improve the icon conflict resolution for complex tagging. For example, if a node is tagged as both a building and a cafe, the algorithm will now always choose the cafe icon because it’s less common.

At HOT, we are working on a collaboration with communities in informal settlements in Sierra Leone as part of the Know Your City project led by Slum Dwellers International.

The remote mapping of the settlements is hard, even with the excellent drone imagery flown by OpenStreetMap Sierra Leone. The environment is really dense, roofs overlap at different heights and structures that look like one from the sky actually include multiple buildings.

However, we have found the use of 3d and 2d imagery renders in parallel to be a bit of a game changer for this mapping activity. The mesh produced from the drone images allows us to angle and tilt in a way that we can better see how roofs interact with each other, what height they are and even sometimes how buildings are divided inside. We think this has vastly improved the accuracy of what we are able to do remotely.

The remote mapping will be followed by comprehensive field mapping and surveying by the local community and the team at CODOHSAPA using the Field Mapping Tasking Manager, so it is important to get the basemap as accurate as possible.

A big thanks to OSM Sierra Leone for their support and collaboration on this project as well as our partners at SDI, CODOHSAPA, Freetown City Council and Catholic Relief Services.

First time writing a diary, I have no idea how this is supposed to work

First off I´m gonna talk about the class:bicycle tag

This tag is used to describe how comfortable a certain way is for a cyclist (with class:bicycle=3 being great and …=-3 being really bad). The tag is mostly subjective and surveys are needed.

I first started using it when OSM based routers kept routing me over a secondary road where it is technically legal (?) to cycle on but rather dangerous due to heavy motor traffic combined with a speed limit of 80km/h. Since only GraphHopper seems to be using the class:bicycle tag for it´s routing it´s the only OSM router which has now stopped telling me to use that road. Great success!

Now fast forward a few weeks and I found out that this tag is extensively used in Munich to “improve” bicycle routing. I don´t fully agree with the way the people there implemeted it as now busy roads are tagged as “better” as seperate cycleways due to irrelevant things such as width.

But I don´t live in Munich so it´s not my problem, so I´d rather focus on implementing this tag in the city of Unterschleißheim. I´ve already done some progress and pretty much every road and path in Lohof-Süd is now equipped with this tag to improve routing, and it did work pretty well as Graph Hopper uses the safer roads even if the route will end up being a few meters longer. Great success again!

I want to implement this tag in other areas of Unterschleißheim but I am not really sure how to make sure that I´ve reviewed every road. I thought about creating a spreadsheet with every road name of the city but that would take a lot of time or good overpass-api skills (which I don´t have). I´ve decided that I would split the city into different sectors and add the class:bicycle tag for those sectors one by one.

About mapillary…

While this doesn´t fit to the rest of the diary I still want to include this as it would help implementing the tag.

I´ve decided that I wanted to add mapillary coverage of Unterschleißheim using my phone attached to my bicycle. After finally figuring out how the mobile app works (thanks to some folks in the OSM-World Discord server) I tried attaching my phone to my bicycle using duct tape. Not professional but if it works why not? I spent about one and a half hours trying to duct tape my phone onto the headlight, making sure that nothing was in the way of the camera but I gave up realizing that I would just look like an idiot cycling around with a phone duct-taped to my bicycle headlight. So that means no mapillary imagery for my city until I´ve figured out a way

We participated in the OSPP hosted by the Chinese Academy of Sciences, which stands for Open Source Promotion Plan. It is held during the summer every year and encourages students of all grades to contribute to open source projects from July to September. This is very similar to GSoC.

Introduction

OpenStreetMap is a map project initiated in 2004 by Steve Coast of the UK, based on the principle of knowledge openness. Its data model enables mappers to represent and abstract complex real-world structures by utilizing three abstract elements types, for instance, public transportation. Since 2016, the OSM Community has submitted projects related to public transport to GSOC annually. The main work is focused on a JOSM plugin called PT Assistant.

Currently, the project we initiated aims to develop a cross-platform editor utilizing a modern front-end technology stack, which is easy to use with clear interactions.

Why do we need this project?

When editing public transportation relations using iD or JOSM, you may often spend a lot of time on tasks such as selecting each segment from the starting point to the endpoint. You might be surprised to find that even at an intersection where you want to turn, the continuous straight line has not been broken for your selection.

We hope to reduce such energy consumption thing for mapper when editing public transportation by automatically calculating possible bus routes through short-distance navigation after mappers specify the stations along the way. The mapper can then fine-tune it so that it conforms to the actual route taken by buses.

At the same time, we also hope to save time in certain situations, such as when creating a group of bus stops with identical names. There is no need for manual maintenance of multiple bus stop signs composed of relations; they will be automatically matched for you. Or when moving a station sign, parking spots are moved automatically.

Overall, our goal is to reduce friction and make it easier and faster for people to create new bus lines.

Project Deliverable Requirements

  • Ability to add stations and create or delete route relationships (with variable member order) within the editor and upload them via OSM API 0.6.
  • Ability to automatically calculate viable routes based on the road network and control points in the map, and automatically split longer paths for easier relationship addition, when only station data is available.
  • Implementation of at least a prototype containing the main functionalities.

Project Technical Requirements

  • Ability to use front-end technology stack to develop complex interface cross-platform programs, with knowledge of WebGL. (Experience with WebGL GIS frameworks such as Cesium.js/MapboxGL is a plus) (Note: Depending on the final choice of technology stack, knowledge of graphics and WASM might be required. She has always admired Meta for being able to create RapiD.)
  • Adequate algorithmic skills, with some understanding of navigation algorithm implementation. (Experience with open-source navigation routing tools like OSRM, Graphhopper, Valhalla, etc., is a plus.) (Note: Actually not such important.)
  • Understanding of the OpenStreetMap data model and API. (Knowledge of community culture and collaboration methods, or previous use of related data for analysis or other purposes, is very important.) (Note: Actually not such important. Since it is a notice posted in the OSM website, we can assume that applicants who see this requirement are already very familiar with it.)

Some important notes

  1. The project language is Chinese and some materials that need to be submitted later are also in Chinese. However, if there are any unclear points about the application, community members can provide language assistance and you can still communicate with your mentor in English.
  2. Although as the mentor, a very ashamed thing is that laoshubaby isn’t very proficient in front-end; this arrangement was originally aimed at students who have no knowledge about OSM whatsoever. Therefore she was chosen as a mentor due to being an active community member.
  3. For non-Chinese students receiving bonuses may take longer - possibly until January or February 2025 - rather than being paid upon completion of their projects. This bonus does not come from OSMChina or TUNA but from OSPP’s sponsor CAS (Chinese Academy of Sciences).
  4. The deadline for student applications is June 3, 2024 at 7:00 AM UTC. The complete guide for students participating in the project can be found at https://summer-ospp.ac.cn/help/en/student/#5-student-bonus (If your browser’s locale cannot be detected, you can click on the “中文/EN” button in the upper right corner of the webpage to switch languages.)
