卫星图像注释叠加地图

虚构海滨城市「Narvel Bay」的卫星图像叠加分析地图，作为情报或环境分析叠加层呈现。底图为超写实俯视卫星视角：棕褐城市街区、深蓝水域、绿色公园、蜿蜒河口三角洲、集装箱码头与机场跑道网格。半透明注释层叠加：黄色多边形标注「Old Town」「Industrial Fringe」「Esplanade Quarter」等主要区域，白色细线指向具体特征，红色圆圈标注兴趣点，蓝色虚线追踪海岸侵蚀边界。刻度尺与坐标格栅以哑光青绿叠加，注释字体为清晰等宽技术字体，呈现军用地图或GIS导出产品的精准分析气质。

A composite satellite-imagery-style map of the fictional coastal city "Narvel Bay", presented as an annotated intelligence or environmental analysis overlay. The basemap is a hyper-realistic top-down satellite view showing tan urban blocks, dark blue water, green park patches, a sinuous river delta, port infrastructure with container terminals, and an airport runway grid. Over this photorealistic base, a semi-transparent annotation layer adds: yellow polygons labelling major districts ("Old Town", "Industrial Fringe", "Esplanade Quarter"), white hairline call-out lines pointing to specific features, red circle markers for points of interest, and a dashed blue line tracing the coastline erosion boundary. A scalebar and coordinate grid overlay are visible in a muted teal. The annotation typography is a crisp technical monospace font, like a military cartographic product or a GIS export. The mood is precise, analytical, and slightly dramatic.
