Rodrigues Island Basemap Data

Access to accurate, current, and precise geographic data are increasingly becoming important. However, required geographic data are often either not available, or not of sufficient quality. Numerous remote sensing techniques are available to users to derive data for a given area. However, these techniques are not always done with a known accuracy rate in mind. Similarly, geospatial methods are not always evaluated for accuracy and precision. Often each method relies on numerous other methods to be completed, introducing errors at any stage. As such, error propagation can become problematic if not accounted for. Aim was at testing the suitability of a combination of open and free methods employed throughout to provide users with geospatial dataset at a known accuracy and scale for an area where the creation of such a dataset would be difficult to obtain due to its general inaccessible geographic location.

The data includes all components of a comprehensive basemap, these symbolized basemaps have also been included within this upload. The data is made avialable as feature classes within a file geodatabase which can be opened within a GIS based software.

准确、实时且精确的地理数据的获取日益重要。然而，所需的地理数据往往要么不可获得，要么质量不足。众多遥感技术可供用户使用，以获取特定区域的地理数据。然而，这些技术并不总是以已知的精确率进行操作。同样，地理空间方法也并不总是经过准确性和精度的评估。通常，每种方法都依赖于众多其他方法来完成，从而在任何阶段都可能引入错误。因此，如果不加以考虑，误差传播可能会变得问题重重。目标在于测试在开放和免费方法组合的适用性，旨在为用户提供已知精度和比例的地理空间数据集，而对于此类数据集的创建因地理位置普遍难以接近而难以获取的区域。数据包括综合基础地图的所有组成部分，这些符号化的基础地图也已包含在本上传中。数据以要素类形式提供，存储在文件地理数据库中，可在基于GIS的软件中打开。
