How to: Satellite Imagery

Whether mapping remotely or in the field, it is extremely useful to have an image of the area to be mapped. If you’re mapping remotely, an image from above is essential, and the higher resolution the image, the more detail you can map. While you can map in the field without a top down image of the area, it serves as a helpful tool to guide your work and allocated tasks. The images used in mapping, that are captured from space, are usually taken from a satellite link/contact and therefore referred to as…Read more

Mapping Dar es Salaam’s Water, Sanitation and Hygiene Facilities

WaSH is a collective term for water, sanitation and hygiene. While each is a separate field of work, they are interdependent in nature. After flooding, communities are very vulnerable to outbreaks of disease such as cholera. Building off a foundation of ongoing response efforts for this in Dar es Salaam, Ramani Huria has started a rapid sanitation mapping campaign within the city’s wards, mainly focusing on public toilets. With the well-trained Ramani Huria team available, this is approached by dividing the team into two groups with two different methods of data collection but…Read more

How to: Street View Mapping

Often when you think of maps, many people imagine only a view from above. Street view imagery allows maps to have an additional dimension, with a view from the ground, as if you were standing on the street! Sometimes also known as Mobile Mapping Imaging Systems, street view imagery can allow you a 360 horizontal (and sometimes also vertical) panoramic view from the ground. Street view imagery can be used in numerous ways, including to take virtual walks & explore landmarks, map key points of interest, and survey solutions. In remote mapping, combined…Read more

Using Drone Imagery to Generate Flood Inundation Models

  Tandale Flood Inundation Model Dar es Salaam is the largest city of Tanzania, it has an estimated 5.5 million residents and is  also an economic centre for Tanzania and East Africa. Offset with this economic and social importance, Dar es Salaam has a tropical climate, experiencing two rainy seasons in a year (April - May and November - December). These seasons are usually accompanied with high rainfall, with high potential for flooding. The main reason for the floods to occur in Dar es Salaam is the mismatched pace of the population growth…Read more

Installing a 3D Printing Weather Station in Tandale

Accurate and precise weather information is critical to preparing for extreme weather events, such as flooding. In Tanzania, the weather forecasts are primarily conducted by the Tanzanian Meteorological Agency (TMA) and are available through their website. But, the forecasts are at a regional level, the question is, how can we get an understanding of weather at a local level? Building the weather station As part of the Code for Resilience, supported by the Ramani Huria, the solution to this is being explored, using open source components such as Arduino and equipment that can…Read more

Creating Worldpop Inasafe Integration

Make the world’s population open data more accessible. As part of procedures in preparing better plans and risk reductions against natural disasters, Disaster Managers need accurate population data for the affected area. This helps in many ways from determining the scale of the disaster, impact assessment and analysis to planning for disaster resilience. There are numerous challenges to accurate population data, some national statistics agencies don’t release this openly, some do not have the resources to create accurate population information. Worldpop provides a solution to this challenge, in providing a platform for global…Read more

Mapping Bicycle Routes During Dar es Salaam’s Cycle Caravan

Each year, 5th June marks World Environment Day, a day for raising global awareness to take positive environmental action to protect nature and the planet Earth. This year’s Sunday 5th June saw UWABA (Umma wa Wapanda Baiskeli; or “Public Cycling Community”), a cycling community in Dar es Salaam in cooperation with European Union, organizing the cycle caravan. This is to support low carbon transport, to promote environmental alternatives to high carbon transport as well as putting emphasis on the presence (or absence) of bicycle roads/routes in the city. With the motivation to do…Read more
