I’m really happy to be part of this team as a digitizer at Humanitarian OpenStreetMap Team in Tanzania (HOT) #0MDTZ . I had effectively participated in tracing roads and Builidings in several projects for instance Mini grid Tanzania, Mini grid Zambia, Uganda refugees mapping and currently we are work out on FB project Western Tanzania Roads. erastold@gmail.com

This is a small update to a sequence of posts on updating some small leaflets originally produced by Andy Allan:–

Yesterday & earlier today this website was producing a HTTP 500 errors (server error, explicitly reported as an error in communicating with a 3rd-party server). It occurred as I attempted to update my post on Printing OSM Promotional Leaflets. I sent an email to the Server folks.

A few minutes ago I succeeded in updating that post but again noticed occasional problems, which appeared to be connected with the Markdown used on this site.

Those paragraphs were a quick heads-up for others that may be attempting to post on this site. Now back to the OSM Promotional Leaflets…

Yesterday I should have reached the end of this little series of posts as the updated leaflets were printed & successfully delivered to my next-door-but-one neighbour. However, looking at them closely I realised that the padding was bad in places. In other words, a bit of a Curate’s Egg.
Right Reverend Host: “I’m afraid you’ve got a bad Egg, Mr Jones!”;
The Curate: “Oh no, my Lord, I assure you! Parts of it are excellent!”

I spent a few hours making a comprehensive fix, then uploaded those changes to GitHub. If/when I use up all the current leaflets & get some more then I shall fix the already-out-of-date photos.

OpenStreetBrowser.org got a new feature update (4.5)! You can now filter category results by certain criteria (e.g. title, type, …).

HOT Tanzania team will be working on the road network of western Tanzania. as a part of the digitization team i m working on this road project.

 The project develops and deliver more accurate levels of the exposure of populations and the built environment to natural hazards in developing countries. The first pilot countries are Nepal and Tanzania, because of their differing exposure and hazard types.

Im Furaha L Mrema, working under Humanitarian open Street map as digitizer,i conduct many projects from different s countries like Congo,Burundi Uganda and Tanzania which based on different s things like a projects of Ebola,floods,min grid etc. i also joined in different s groups which found under HOT like soil analysis and data recording, im fill very precious to work under HOT.

 Mapping and validation for minigrid project of Tanzania, Zambia and Zanzibar to help determine which villages may be appropriate for solar and other renewable Mini-Grid electrification.

 Ramani Huria and Green Waste Pro project purposeful to tag buildings and use the process for collecting trash and revenue from waste producers Dar es Salaam Tanzania.

Gwantwa Andrew, Junior Supervisor at Humanitarian OpenStreetMap Team (HOT) local partner, Open Map Development Tanzania (OMDTZ)

I joined HOT as a volunteer mapper in March 2015. I was one of the first few students selected from Ardhi University to work with this organisation, when it started operating in Tanzania. My first professional engagement with HOT was in a project called Community Mapping for Flood Resilience in Dar es Salaam city. My responsibilities in this project revolved around collection of spatial data on housing and related infrastructures in twenty six wards in the city. Later on in this project, i played training and supervisory role on new students who joined the project. At the end of this project, we produced maps showing all flood prone areas in the surveyed wards. The maps were meant to be used as important tool for flood prevention and management at community level.

I also worked in a project on Malaria Elimination in Zimbabwe. My tasks in this project was to map all buildings targeted for malaria prevention intervention. Mapping in this project was done remotely using open source software namely JOSM and id Editor. This project was successfully accomplished in 2017 and it was handed over to the government of Zimbabwe for other actions.

My third major project that i participated at HOT was a Mini Grids project Tanzania. The purpose was to identify all buildings not connected to the power supply through the main national grid in order to plan for them to access power from solar and other renewable Mini Grid electrification. I successfully supervised a team of 78 mappers and the work was accomplished within 5 months on July 2018.

I also worked in Shina Mapping project in Dar es Salaam city. The objective in this project was to produce maps that allows Amana hospital at Ilala district to do the registration and collection of information on patients records from the lowest administrative boundary called Shina. My involvement in this project was to collect data on Shina boundaries and update them into the open data kit.

Currently i am supervising mapping activities in a project called Facebook Road Import. The onset of this project follows quest by Facebook to seek for means of using mapping techniques to enhance quality of data and facilitate spatial identification of Facebook users. This is an exciting project as it involves state of the art techniques and software such as map roulette and machine learning for tracing. These are rather new mapping techniques and it is therefore an opportunity to learn and enhance my knowledge and skills in various editing and validation programs.

Hi, this is a brief explanation of my contributions to the Humanitarian OpenStreetMap Team (HOT) basing in Tanzania.

In July 2017, it was my pleasure to join HOT as a volunteer mapper where I was able to contribute to the project of Dar Raman Huria through tracing roads and buildings. The project aims to create map data which will be potentially useful in helping communities to prepare and escape from floods.

In the mid of February 2018, I was appointed to be a supervisor in digitization team. Within my role as supervisor, I have been ensuring the quality of the data provided by digitizers through revising their works done every day, creating tasks to be performed, taking statistics of digitized buildings or roads, preparing the payment sheets for digitizers after every two weeks, and reporting to the project manager about the progress of the work. As a supervisor, it is also my responsibility to guide the team and to understand the reasons behind why we are digitizing.

Here are the projects I worked on as a supervisor, Minigrid Tanzania, Minigrid Zambia, METEOR project and Facebook roads Import (Western Tanzania Roads)-on going project.

Feel free to contact me through my email(s) doricelucas2@gmail.com or doricelucas24@gmail.com for any query.

Dar es Salaam is one of the fastest growing cities in Africa, with an annual population growth of over 5.7%. In 2002 there were approximately 2.5 million inhabitants, increasing to 4.4 million in 2012, and currently estimated at over 5.5 million.

Severe flooding in December 2011 - January 2012 displaced at least 10,000 people in Dar es Salaam and caused 40 deaths. Heavy rains in April 2014 also led to widespread flooding and infrastructure damage. Climate change is expected to exacerbate these trends, as Tanzania’s coastal region is likely to experience heavier, more concentrated rainfall events. Increasing frequency of floods, landslides, and other hazards is expected to impact the most fragile, unplanned parts of the city.

In 2015 HOT began an initiative to mapping infrastructure data in various parts of Dar es Salaam. During this project I participated as a community map surveyor using GPS, Field paper. and JOSM software.

Now in its second phase, Ramani Huria 2.0, which began in 2017, is combining exposure data and flood hazard data to conduct risk analysis of potential future disasters. The team are using community mapping techniques to engage with local leaders and teach community inhabitants free, open source data collection tools from their smartphones. The data collected is enabling people across all levels of society to improve flood mitigation plans and raise awareness and resiliency to natural threats. This time I participated as a GIS expert dealing with cleaning drainage data from the site.

I Neema Alphonce, a mapper at Humanitarian OpenStreet Map Tanzania(HOT) and Open Map Development Tanzania (OMDTZ) . I started working since July, 2017as volunteer and participating in different projects such as Dar es Salaam Flood Resilience, Minigrid Tanzania, Zambia and still participating in Western Tanzania Roads project which is in progress. In January 2018 i became a mapper supervisor which i was responsible to provide training on how to map or digitize and to do validation to new mappers. So i gained much experience in digitization and validation of buildings and roads. For more information contact me on my email ( alphonceneema15@gmail.com ) thank you.

i joined Humanitarian open streatmap team [HOT] December 2017 as a Digitizer. And as a member of this organization i have got a lot of different skills following different projects that we have already done and that we are still doing.Some of the project that i effectively participated in doing are Mini grid Tanzania,Mini grid Zambia and now we are carrying on with FB project.

Hey! it is Charles Frank, i have been working cooperatively with Humanitarian OpenStreet Map Team(HOT) #OMDTZ as a youth mapper since early last year.I have been a part and parcel of various projects like Minigrid Tanzania up to recently Western Tanzanian Roads. It is my pleasure to become an expert of digitizing buildings as well as roads via editing tools such as JOSM and Id Editor.I expect to become even much better competent mapper by interacting with my leaders and fellow mappers on learning new tactics simultaneously,let us share skills and thoughts via my email: charleskanjunju@gmail.com

Did you ever come across wiki pages like Proposed Features/UUID or Yahoo! Aerial Imagery and wondered what to do with the information as the pages are not “current” any more?

As one could have guessed, there are basically two approaches on these cases. One approach is to store current information only and consequently delete information as soon as it becomes historic. The other approach aims at documenting the full history of all tagging and all applications ever used.

The strongest reason for the first approach is the argument that historic information might be confusing for the readers and might lead to “wrong” tagging or poor decidions regarding software deployment. Referring to my first example, one can see that the page features two red boxes. Both state that the proposed feature is abandoned. There are links to Query-to-map and Humanitarian OSM tags (marked as outdated itself), but a link to the general concept page Permanent ID featuring the background as well as an overview of the approaches is missing. On the other hand, this page serves as a documentation for the keys uuid:place and similar. This information might be lost if someone would delete the page or radically change its content (in the latter case you could still retrieve the content from the page’s history in case you know the page name).

Trash or recycle? (Image CC0)

Secondly, some users argue that outdated pages (esp. proposals) lack unique and thought-through ideas and therefore the reason to be “worth” archiving. The analogy is an outdated technical guide describing steps for installation which can not be done any more because the systems necessary to run the installation are unavailable today as technology has advanced significantly and new APIs have emerged whilst other services have creased to exist. The other side argues that understanding the history helps understanding current OpenStreetMap. An illustrative example is provided by Yahoo! Aerial Imagery. Providing the means of armchair mapping, Yahoo’s imagery paved the way for a new mapping technique at its time. The step from Yahoo-provided imagery to current Bing’s services seems small compared to tracking GPS outside only and tracing aerial imagery at home.

Facing the challenge that outdated pages are marked differently and sometimes not at all, wiki users have come up with templates like Template:Archived proposal or (more recently) Template:Historic artifact start. The templates do not solve the dispute itself but hopefully avoid misunderstandings regarding currentness.

The decision what to include in the documentation of OpenStreetMap’s history has not been made yet. There are still reverts of edits in this case. A number of pages about former render software “Kosmos” is marked for deletion. I hope we will eventually find a solution together.

The following questions need to be assessed in my opinion:

I would like to discuss this in the forum: https://forum.openstreetmap.org/viewtopic.php?pid=736510#p736510. Please feel free to join.

Relation 3444486 is an absolute mess. Do not know whether to fix it up or create a whole new one. The relation was created by someone in Denmark. Need to figure out which way to go. Also want to change a side trail in relation so it stands out. Looking for someone locally to help either fix relation or create new one.

Hi ….

My name is Samwel Kyando, I became part of the team in 22 march 2018, of which i was trained on how to use JOSM as a tool for mapping,

Till today I’ve contributed mapping different countries like, Minigrids Tanzania, Minigrids Zambia, mapping for ebola (UGANDA), Road mapping UGANDA, missing maps:AL Abdali Amman, for more info about my edits please review https://tasks.hotosm.org/user/Samwel%20Kyando?task=637#bottom

2019 is a new beginning for me to keep clicking and to keep mapping for Humanitarian OpenStreetMap Team..

Thanks

A year has gone since i joined as Humanitarian digitizer at Humanitarina OpenStreetMap Team (HOT) and contributed to the extent in different projects specifically on digitizing buildings and roads. Currently, I am digitizing roads on FB Project Western Tanzania Roads.

WOW!!! Actually i’m very Happy to be part of this project.

Today I’ve added more highways which were not digitized before..I’ve also modified some highways classification and align the road properly with the imagery.

Generally my plan is to be more active and get involved in more Hotosm projects.

Thanks.

hello! am jamal amani, am working with Hot Tanzania #OMDTZ. im very happy to be part on the osm family, now am working on this project of facebook.
