About this dataset

[Initial analysis] The database contains information about buildings identified by Google outside of settlements recognized by GRID3. It serves as a proxy for identifying potential new settlements or areas of urban growth. The analysis incorporates two levels of clustering: one at a distance of 500 meters and another at 100 meters. The 500-meter clustering helps identify broader areas where multiple buildings are concentrated, potentially indicating the presence of a new settlement or an expansion of an existing one. This distance threshold allows for the initial identification of potential new settlement areas. The 100-meter clustering provides a more granular view, highlighting tighter clusters of buildings within the broader 500-meter areas. This finer level of clustering aids in distinguishing individual settlement units or neighborhoods within the larger potential settlement areas. By combining these two levels of clustering, the database facilitates a comprehensive analysis of potential new settlements or urban growth areas. It enables researchers, urban planners, and policymakers to identify and prioritize areas for further investigation, resource allocation, or development planning.

Documentation

GIS Analysis by combining Google's Open Building Data with Settlements from GRID3. Additional Analysis Required: The dataset provides an initial indication of potential settlement expansion areas based on building clusters detected outside recognized settlements. However, further analysis is necessary to validate and confirm the nature and status of these areas. Additional data sources, such as high-resolution satellite imagery, population data, and local knowledge, should be incorporated to refine the analysis and ensure accurate identification of new or expanding settlements. Need for Remote Sensing and Ground Truthing: While the dataset relies on Google's building identification, it is crucial to complement this information with remote sensing techniques and ground truthing efforts. High-resolution satellite imagery can provide valuable insights into the physical characteristics and patterns of the identified areas, while ground truthing through field surveys or local stakeholder engagement can verify the actual presence and status of potential settlements. Temporal Considerations: The dataset represents a snapshot in time, and settlements are dynamic entities that can change rapidly. Regular updates and monitoring of the identified areas are recommended to capture any changes or new developments in settlement patterns over time. Contextual Factors: The interpretation and utilization of the dataset should consider local contexts, including socio-economic factors, cultural practices, environmental conditions, and development policies. These contextual factors can influence settlement patterns and should be taken into account when planning interventions or making decisions based on the dataset. Data Limitations: It is important to acknowledge the potential limitations of the dataset, such as the accuracy of Google's building identification algorithms, the resolution and currency of the underlying data sources, and any inherent biases or errors that may exist. Users should exercise caution and critically evaluate the dataset in conjunction with other reliable sources of information.

Ethiopia - Settlements with administrative boundaries

The GRID3 ETH - Settlement Extents v3.0 consists of a geographic representation of settlements in Ethiopia. Data inputs and methodology are described in data release notes available at GRID3 ETH - Settlement Extents v3.0 3iS has enhanced the settlement dataset by integrating administrative attributes from a shapefile at the Admin 3 level. This process involved associating settlements with the corresponding administrative divisions, including the following attributes: - Admin 1 (Region) Names and P-codes: Identifying the broader regions where settlements are located. - Admin 2 (Zone) Names and P-codes: Associating zones within regions to each settlement. - Admin 3 (Woreda) Names and P-codes: Providing detailed locality-level information.

Populated Places of Ethiopia

Settlements and residential areas: named cities, towns, villages, suburbs, and residential land (`place=*` and `landuse=residential`). Useful for demographic context, settlement-level targeting, and population analysis. Coverage reflects where volunteer mappers have been active. Urban areas are usually well represented, remote areas may be sparse. Cross-check critical decisions with local field knowledge. - Source: OpenStreetMap, a free, collaborative world map - Tags: place, landuse - Part of the country exports on HDX by HOT

Ethiopia - Populated Places GeoNames

This dataset represents populated places in Ethiopia at the locality level, including villages, kebeles, towns, and other administrative divisions. Each entry is associated with XY coordinates and is integrated with Ethiopian administrative boundaries. The data originates from the National Geospatial-Intelligence Agency (NGA) and is accessible through their GeoNames platform(https://geonames.nga.mil/geonames/GNSData/).The dataset includes various types of populated areas such as: villages, kebeles and towns. This dataset is crucial for various applications, including urban planning to assist in the development of infrastructure and services based on population distribution, for research, and on disaster management to support humanitarian efforts by identifying populated areas during crises.

GRID3 KEN - Settlement Extents v3.0

The two layers contained within the GRID3 KEN - Settlement Extents v3.0 include: GRID3_KEN_settlement_extents_v3.gpkg: a spatial layer representing settlement polygons. GRID3_KEN_settlement_grid_v3.gpkg: a spatial layer representing the centroids of settled grid cells. The current version supersedes GRID3 KEN - Settlement Extents v2.0; the following changes were made: Development of a new methodology to derive building counts and settlement polygons with open data. Estimation of a probability value for settlement polygons Addition of a building-area measure Replacement of degree of urbanization with classification based on built-up areas, small settlement areas, and hamlets Elimination of building-count ranges Elimination of variable comparing to previous versions For more information on data inputs, methodology, and codebooks please see the Data Release Notes.
