之前在做shp数据导入Geodatabase中时，程序运行出现错误提示：“The spatial index grid size is invalid”。 后来查阅esri帮助找到了原因。是LoadOnlyMode的问题。记下来，以后好好研究。 http://support.esri.com/en/knowledgebase/techarticles/detail/35007 Error: The spatial index grid size is invalid Article ID: 35007 Software: ArcGIS - ArcEditor 9.3, 9.3.1, 10 ArcGIS - ArcInfo 9.2, 9.3, 9.3.1, 10 ArcGIS - ArcView 9.2, 9.3, 9.3.1, 10 Platforms: N/A Error Message When creating a new feature through either the CreateFeature and Store method or the use of an InsertCursor, the creation fails with the following error: "FDO_E_INVALID_GRID_SIZE -2147216894 The spatial index grid size is invalid."Cause The FDO_E_INVALID_GRID_SIZE error is raised because the grid size of the feature class where the feature is being created is too small to handle the feature. This error only occurs with File or ArcSDE Geodatabases. Solution or Workaround Depending on how the error message is being raised, there are two different ways to handle the error. If this error is encountered while editing within ArcMap, recalculate or modify the grid size of the feature class to accommodate the new feature. The recalculation of the grid size must be done from the Feature Class properties dialog box within ArcCatalog. This requires the use of the Stop Editing function, save any edits, and close the Map Document containing the feature class. For steps on how to recalculate or modify the grid size of a feature class, see the following Web help documentation: Setting spatial indexes.If this error is being encountered programmatically through the ArcObjects API, notifying the user to manually modify the spatial index is not an ideal solution. Instead, this error can be prevented by placing the feature class into LoadOnly mode prior to inserting the feature. When the feature class is taken out of LoadOnly mode, the Geodatabase automatically recalculates an appropriate grid size. The following code sample demonstrates how to use LoadOnly mode with a feature class: 'Place the feature class in loadonly mode. This steps needs to happen prior to calling IFeature.Store or IFeatureCuror.InsertCursor Dim pFCLoad As IFeatureClassLoad Set pFCLoad = pFeatureClass pFCLoad.LoadOnlyMode = True 'Create feature buffer Dim pFeatBuffer As IFeatureBuffer Set pFeatBuffer = pFeatureClass.CreateFeatureBuffer Set pFeatBuffer.Shape = pGeometry 'Create insert cursor and insert buffer Dim pCursor As IFeatureCursor Set pCursor = pFeatureClass.Insert(True) 'Insert the feature and call flush pCursor.InsertFeature pFeatBuffer pCursor.Flush 'Take the feature class out of loadonly mode, the Geodatabase will calculcate an appropriate grid size based on the features within the feature class pFCLoad.LoadOnlyMode = False |
