STEM Youth Boot Camps are a Projekt Inspire initiative. This initiative helps to improve the quality of secondary…Read more

How to: Ground Survey Mapping with Aerial Imagery

The ground survey mapping process undertaken by the Ramani Huria team depends upon high quality aerial imagery. Mappers collect data on site with the help of the field papers produced by drone images (mbtiles) that offer direction and location to the mapper. Equipped with GPS units, Ramani Huria team members mapped all city centre wards using this approach. These include Kivukoni, Kisutu, Kariakoo, Jangwani, Gerezani, Mchafukoge, Upanga Mashariki and Upanga Magharibi. Ground survey process with the help of aerial imagery First visit the fieldpapers website and make field papers for the area upon…Read more

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
