Calibration data for Infratructure mapping in Svalbard

This dataset contains geographical features representing selected infrastructures (houses, roads, airfield, pipelines etc.) in the town Longyearbyen on Svalbard.

Each feature has attributes listing relevant classifiers, such as:

- the type of infrastructure (residential building, road, pipeline, etc.)

- the shape of the feature (flat, sloped, pitched, domed, barrel-shaped)

- the type of surface material (wood, concrete, asphalt, etc.)

- the background setting (rock, sediments, sea, etc.)

- its current status as actively used or inactive infrastructure.

All feature locations and attributes have been validated either by on-site inspection, or by Google Street View imagery (validation method indicated in feature attributes).

Photos are provided for most of the features that were field validated.

Latitude: 78.223000 * Longitude: 15.650000

本数据集包含斯瓦尔巴群岛（Svalbard）朗伊尔城（Longyearbyen）境内选定基础设施的地理要素，涵盖住宅、道路、机场（airfield）、管道等类型。

每类要素均配有包含相关分类标识的属性字段，具体包括：
- 基础设施类别（如住宅建筑、道路、管道等）
- 要素形态（如平坦、倾斜、坡顶、穹顶、桶形等）
- 表面材质类型（如木材、混凝土、沥青等）
- 所处背景环境（如岩石、沉积物、海洋等）
- 当前使用状态：活跃使用或闲置的基础设施。

所有要素的位置与属性均通过实地勘查或谷歌街景（Google Street View）影像完成核验，核验方法已标注于对应要素的属性字段中。

多数经实地验证的要素均配有配套实拍照片。

覆盖范围：
纬度：78.223000，经度：15.650000
