Sander de Haas presented the work SamSamWater has been doing on refugee camps and crisis response mapping during the Google Geo for Good 2019 Summit.


Partner Panel presentation on Maps for crisis relief by Sander de Haas

During the summit they organised a a build-a-thon where particpiants from different organisations could build a project using mapping tools, collaboratively. Together with Christian Thomas & Brendan Jarrell of SkyTruth, Sander worked on a Map Toolbox for humanitarian aid workers. This Map Toolbox can support humanitarian aid workers in the planning and management of refugee camps and make information quickly available in crisis situations.

At the end of the summit a functional first version of the toolbox was presented and the team won the build-a-thon award for ‘Best Social Impact’! We are very proud of this!

This prototype shows the concept works very well, now we have to extend the toolbox to include more data sources and add extra functionality. We will use this prototype to find partners (both technical and funding) to bring this to the next level. If you are interested, please contact sanderdehaas@samsamwater.com.

In complex emergencies, information management is becoming increasingly important and a useful tool for assessment, planning of water and sanitation infrastructure and coordination.

DSS water, with the support of SamSamWater, is organizing a 2-day training on GIS and Google Earth on the 4th and 5th of September 2019.

The training is recommended for all water, sanitation and hygiene experts who consider being deployed by DSS water, or for professionals working within WASH in the emergency sector, with a basic working knowledge on GIS and Google Earth.



The first day of the training will provide a basic, general understanding of Google Earth in relation to WASH practices, and thereby addresses the basics of navigation, historical imagery and time series, map editing, georeferencing maps and importing excel files. The second day will continue on this knowledge, covering more advanced skills on geo tools and analysis for WASH projects, including exercises on mobile data collection and GPS measurements with smartphones. The training will use some of the practical experience of experts deployed as IM in emergencies.

The training is free of charge and will take place from 9:00 am till 16:30 pm at the Netherlands Red Cross office in the Hague (Anna van Saksenlaan 50).

Are you interested in broadening your knowledge and would you like to attend? Please register as soon as possible (deadline is July 31st), by sending a short motivation (max. 200 words) and CV to dsswater@rvo.nl.

We are very proud to officially launch Greener.LAND today at the 2019 Global Global Landscape Forum in Bonn.

Greener.LAND

Greener.LAND is an easy-to-use, intuitive, free and open-access online tool to educate and assist landscape practitioners on restoring their landscapes. Greener.LAND has been developed as a collaboration between Nature^Squared and SamSamWater.

It has already been featured in an article and is part of the official program, at 12:30 at the Learning Cafe.

And for our LinkedIn audience, we provide a sneak preview: www.Greener.LAND. We are curious to hear what you think, so please provide us with feedback through our survey.

After hearing about the devastating impact of cyclone Idai in Mozambique, Malawi and Zimbabwe, we thought it might be helpful to compile a map repository where maps and satellite data are from all different sources are combined.

We have combined topographic maps, elevation data, rivers, houses and many more in 1 online platform for easy viewing on both desktop and smartphones. The maps can be viewed here:
https://samsamwater.com/idai

If you navigate to the “Layers” tab you can toggle all the different layers.
There’s a range of maps from different sources. I’ve highlighted a few map types and possible uses below.

Topography
A detailed topographic map (left) compared to OpenStreetMap (right). The topographic map shows much more details including (unpaved) roads, swamps and small streams. The topographic map is old (made by the Soviet military in the 1980’s) so don’t rely on it for settlements, but landscape features (like wetlands) and roads are often still very accurate.


Hydrology
An easy overview of all watersheds (catchments), rivers and tributaries in the region and (in dark blue) the extent of the flooding:


Elevation
Left: Elevation map (only for elevations from 0 to 50 m above sea level for increased contrast)
Mid: Elevation map + flood extent map (derived from satellite imagery by ESA)
Right: Elevation + flood extent + buildings (mostly houses, derived from OpenStreetMap)

I’ve also added an elevation map in the platform for the full area (from 0 to 2500 m+MSL) which might come in handy for areas more upstream. And you can change the transparency of the individual layers using the sliders.

If you zoom in you can see that, luckily, most houses are constructed on the higher grounds, but maps like these could be used to identify priority areas such as where people might be trapped:


If you are working on something where maps like these could be helpful, please let me know and I can think along with you and see what data is available and how we can visualise that in the best manner.

The program for the workshop in the use of GIS, Smart data collection and data visualization for WASH professionals can be found here: Program and info GIS tools for WASH workshop.

The location of the workshop is the new office of the Red Cross in The Hague close to NS station Laan van NOI:
Red Cross office, Anna van Saksenlaan, 2593 HT, The Hague
(this is a different location as communicated earlier!)

SamSamWater, DSS Water, Red Cross and 510 organise a workshop on the use of GIS, Smart data collection and data visualization for WASH professionals.

This practical ‘hands-on’ workshop will explore the possibilities of finding and using secondary data to understand local conditions in the field. You will learn how to digitally collect data, use mapping software, import field measurements (i.e. GPS measurements) and combine maps with field experiences. Mostly practical exercises and some theory will make up the workshop in order for WASH delegates to start using and collecting data in a standardised manner, for sustainability purposes.

Duration: 2 days
Date: 7-8 June
Maximum number of participants: 20
Organisers: DSS water with support of Red Cross, SamSamWater and 510
Location: Red Cross office, Anna van Saksenlaan, 2593 HT, The Hague

Are you interested to participate in the workshop? Please send an email before the 3rd of May 2018 to dsswater@rvo.nl

Practical hands-on workshop for GIS and other digital tools for WASH

Over the past few weeks Lucas Borst and Sander de Haas of SamSamWater worked on a project for UNHCR, the UN Refugee Agency. The goal of the project was to provide insight in the possibilities and potential of online data sources and tools for smart measuring, data collection, information sharing and visualization for refugee camps.

Mtendeli refugee camp in nortwest Tanzania was selected by UNHCR as a case study for this project.

Together with UNHCR, the Netherlands Enterprise Agency (RVO), the Netherlands Red Cross and TCRS we collected a whole range of datasets, maps and information for the camp. Some are based on field measurements, others satellites and we are even using scanned maps made during colonial times.

Having access to these maps and data on WASH is incredibly valuable for UNHCR, partners and experts. And combining different types (‘layers’) of data can give additional insights, improved knowledge, higher quality and cost reduction.

See the presentation below for a full overview of our findings and 4 case studies on how to use this data to solve actual issues in the refugee camp.



We’ve also made an interactive online map where you can explore all maps and layers, or you can download the full dataset in Google Earth format here.



Next to the topographic and geological maps of Kenya we have now added 161 reports on the geology of Kenya.

Geological information is often essential for many water and sanitation projects, but it’s often difficult to find detailed geological information and maps. Recently we received a large collection (over 300!) of scanned geological and topographic maps of Kenya. Most of them are old (from 1940’s to 1980’s), but still very useful.

We therefore made all these maps available on our website:
Geological maps of Kenya
Topographic maps of Kenya

The maps are very detailed and scanned at a high resolution.



If you own the rights to any of these maps and don’t want them to be published here, please contact us and we will remove them from this website.

If you have other maps (e.g. topographical, geological, hydrological) which you would like to make available to others, please contact us so we can help you to publish them.

Once a year Google hosts the ‘Geo for Good User Summit‘ where they invite mapping and technology specialists in the public benefit sector, who are actively working on projects related to mapping. SamSamWater was invited to join this event to learn, share and meet with the Google Earth Outreach team and other mapping specialists.

Sander de Haas gave this ‘lighting round’ presentation on how SamSamWater and Justdiggit are using geo information and mapping tools for their work in Africa.
