报错提示: Feature (52) from “site1” has invalid geometry. Please fix the geometry or change the “Invalid features filtering” option for this input or globally in Processing settings. 原因: 可能是文件本身从kmz转过来的,存在无效的地理单元。 解决方案: 1.使用Qgis内的矢量修复工具。 2.将修复结...
错误原因 QGIS内部自带专门的解决方案,选择Vector geometry 下面的Fix geometries algorithm工具,搜索,打开,把原始文件作为输入,点击运行。 运行fix geometries 针对得到fixed geometry,再运行zonal stastics,就不存在问题了。(在参考的资料里,还需要手动编辑下边界,在本案例中边界没有改动,不存在这个问题,所以到此就在...
简介:QGIS【实例 01】筛选范围内的数据相交intersection工具使用及Feature (347897) has invalid geometry问题处理 1.筛选某个城市的路网数据 主要使用到的是处理工具箱里的矢量覆盖->相交(intersection)工具,需要注意的是: 输入图层是被筛选的数据(举例使用的是全国路网数据); 叠加图层是筛选工具(举例使用的是区划区...
Back in the main QGIS window, you will see a new layerColoredadded to theLayerspanel. Notice that the new layer is missing a state which had invalid geometry. We now know that this particular state polygon had invalid geometry but we don’t know what was the cause. We can easily find ...
I tried with a new QGIS profile Additional context I don't know if this also happens in previous versions Can I only use the Split Parts tool on a polygon once? Yes The second time throws an error of: "Geometry is invalid" I don't think the "2 parts" works either although I'm ...

In trying to correct this 1 error, I have tried the following (1) added a zero distance buffer using QGIS default plugin (2) added a zero distance buffer using GRASS v.buffer.distance (3) used multiple permutations of GRASS's v.clean & v.clean.advanced But none of the above has rec...
Looking at the QGIS API Documentation: bool QgsFeature::hasGeometry Returns true if the feature has an associated geometry. Is invalid geometry different from a feature having no associated geometry? If so, is there a tool like .hasGeometry in PyQGIS that returns whether or not the geometry...
