Satellite imagery analysis: Historical and geographical context of Elmina Castle and its surroundings

 




Historical and geographical context of Elmina Castle and its surroundings.

Analysis of the map above

The map presents an aerial view of Elmina, a coastal town in southern Ghana, with a focus on the Elmina castle and its immediate surroundings. The map combines satellite imagery with mapped outlines of key features. The coastline is highlighted in a soft pink shade, marking the natural edge of the land. The Atlantic Ocean is identified in blue, occupying the right and lower areas of the frame. The castle is enclosed with a red outline, showing its compact but prominent position at the meeting point of land and sea.

The urban area appears dense, with tightly packed buildings and narrow street networks. This pattern suggests a long-established settlement where structures have developed organically over time. The harbor area, seen as a small inlet filled with canoes, reveals the continued significance of small-scale fishing. The map’s orientation, supported by the north symbol in the upper section, directs attention to the relationship between the built landscape and the coastline, which shapes much of the town’s physical and economic life.

Historical Context of Elmina Castle

Elmina Castle is one of the oldest European structures built south of the Sahara. Erected by the Portuguese in 1482, it served as a fortified trading post. Initially, it functioned within networks of commerce involving gold, ivory, and other local products. By the seventeenth century, its purpose shifted, becoming a major center of the trans-Atlantic slave trade.

Control of the castle changed several times, passing from the Portuguese to the Dutch in 1637, and eventually to the British in the nineteenth century. Each phase reshaped the town’s political and social life. The castle operated not only as a military base and trading station but also as a symbol of European expansion along the West African coast. Today it stands as a UNESCO World Heritage Site, serving as a reminder of global exchanges, historical trauma, and cultural resilience.



Economic Activities of the Immediate Community

Elmina remains an active coastal settlement where traditional livelihoods continue to define local life;

Fishing and Related Trades

Fishing is the dominant economic activity. The harbour shown in the map is filled with wooden canoes, which reflects a vibrant artisanal fishing sector. The community also engages in fish processing, including smoking, drying, and selling fish in local and regional markets.

Tourism

The presence of the castle attracts domestic and international visitors. Tourism related businesses, small hotels, guesthouses, restaurants, and craft vendors support income generation for residents.

Small-Scale Commerce

The dense market areas suggest active small businesses that include food vending, retail trade, and services. These enterprises rely on the central location of the town and its accessibility by road.

Boat Making and Carpentry

The visible concentration of boats along the shore indicates local craftsmanship. Canoe building remains an important skill, supporting both fishing and tourism.

Morphology of the City

The town has an irregular but coherent structure rooted in historical development;

Dense core settlement: Buildings are closely spaced, forming a compact urban form typical of older coastal towns influenced by centuries of trade.

Organic street pattern: Streets appear narrow and winding, shaped by natural movement patterns rather than systematic urban planning.

Harbor-centered growth: Much of the built environment radiates outward from the harbour and castle, underscoring the importance of coastal activity.

Mixed-use landscape: Residential, commercial, and fishing related activities coexist without strict zoning, creating a highly integrated urban setting.

Coastal edge settlements: Homes and workspaces extend toward the waterfront, showing how the community organises its daily life around the sea.

Topography

The map suggests a relatively low-lying coastal terrain. The shoreline curves gently, and waves breaking along the natural coastline highlight the flat, beach-like nature of the land. Slight elevations occur inland, visible from the clustering of buildings that appear to sit on slightly higher ground.

This topography enhances the town’s suitability as a harbour but also exposes it to environmental pressures such as coastal erosion, tidal flooding, and sea-level rise. The position of the castle on a rocky promontory reflects the strategic value of higher ground during its construction.

Environmental Importance to the Immediate Community

The coastal environment plays several vital roles;

Provision of Livelihood

The sea supports fishing, which is central to the community’s food security and economy. The shoreline and harbour areas are workspaces that sustain thousands of households.

Cultural Heritage

The coastline and castle together form a cultural landscape that holds deep meaning. Community ceremonies, fishing rituals, and tourism all depend on the health of the coastal environment.

Natural Protection

The natural coastline, visible in the map, acts as a buffer against ocean waves. Rock outcrops and beaches help reduce the effects of erosion and storms, though increasing environmental stress now challenges this natural shield.

Tourism and Education

The scenic coastline and historic structures attract visitors, researchers, and educators. These interactions encourage conservation, economic activity, and cultural preservation.

 Conclusion 

The map highlights the close relationship between Elmina’s physical landscape, its history, and the daily life of its people. The castle stands as a lasting monument to centuries of global trade, conflict, and cultural contact, while the surrounding town reflects a long tradition of fishing, commerce, and craftsmanship shaped by the sea. The dense settlement pattern and informal street network show how the community has grown around its natural harbour and coastline, using the land in practical and adaptive ways. Although the low-lying terrain offers economic advantages, it also makes the town vulnerable to coastal pressures. The coastal environment therefore remains essential not only for work and heritage, but also for the town’s resilience. Together, these elements show how history, geography, and the environment continue to shape Elmina’s identity and future.

Simulation of flooding in Keta municipal district

Image
https://doi.org/10.13140/RG.2.2.26871.89762 The maps above illustrate the spatial extent of simulated flooding in the Keta, Abutiakope, Dzelukope, Tegbi, and Woe areas along the coast of the Volta Region, Ghana. The simulation employs a raster-based modelling technique to visualise progressive sea-level rise scenarios at 1 m, 2 m, and 3 m elevations above current sea level. This approach provides a visual representation of the potential impacts of coastal inundation due to climate-induced sea-level rise (SLR). Analysis of the Maps Map 1 serves as the baseline, showing the existing land cover and settlement pattern without sea-level rise. It highlights the dense coastal settlements and infrastructure in low-lying zones, which are inherently vulnerable to inundation. Map 2 (Sea Level +1 m) demonstrates the initial stage of flooding, where a 1 m rise leads to noticeable encroachment of seawater inland, particularly around the lagoonal systems and coastal fringes. The inundation is concent...

Geospatial analysis: spatial structure and environmental setting of Central Makkah-Saudi Arabia, a satellite-based assessment

Image
  The map above shows a detailed satellite-based assessment of central Makkah, with particular focus on the urban core surrounding the Sacred Mosque. The annotated features illustrate the spatial arrangement of public services, natural elements, and key infrastructures. The area displayed is highly built-up, marked by dense construction, a complex network of roads, and multiple service facilities such as hospitals, schools, police stations, and transport nodes. Distinct symbols highlight trees, peaks, parking areas, and various public institutions, offering a clear view of how urban functions are distributed around the city’s central religious site. Makkah’s religious importance defines much of the spatial pattern visible here. The urban fabric becomes increasingly concentrated toward the center, where the holiest site in Islam is located. This concentration shapes the flow of movement, leading to the development of major roadways, pedestrian routes, transport stations, and support...
