WFS scattered orchard survey (remote sensing)
收藏资源简介:
The data come from a nationwide survey of the orchard trees using photogrammetric aerial images with a spatial resolution of 40 cm, i.e. 6.25 points/m² (flying 2015-2018). Trees with a height of between 3 m and 20 m are addressed according to a specific classification scheme and taking into account the other parameters as scattered fruit trees. Not all trees were classified with the same trustworthiness. Shown are points in tree classes 3-5, where the probability of them being scattered fruit trees is comparatively high. Each point represents a single tree. Please note the following information on the completeness and quality of the data provided: due to inaccuracies in the acquisition of technical objects, there are occasional non-valid geometries according to OGC Schema validation. Since GIS servers such as ArcGIS server, GeoServer or UMN MapServer have to use/process ever more accurate data bases, the inspection routine is always further developed and warns in the tolerance range as well as in the topological recording of inaccuracies (e.g. by third-party software). This means that geometries can no longer be displayed or recorded. The objected geometry errors include self-intersections (self-intersections) or double bases. Therefore, the LUBW cannot guarantee the completeness and stability of the Download Service (WFS). If necessary, please check the completeness on the basis of the presentation services also offered (WMS).
