Working with a file geodatabase, I attempted to insert a large polygon feature and received an error: Spatial Index Grid Size is Invalid. The default cell size when a feature dataset is used as input to a tool is to take the width or height (whichever is shorter) of the extent of the feature dataset, divided by 250. Setting up the spatial index means balancing the cell sizes—smaller cell sizes mean more cells per shape, which require more entries in the spatial index table. Spatial Grid 1 is the first, or lowest, grid level and has the smallest cell size. 2016-03-15 11:30:19,867 ERROR rid=24 'worker-1976' Core - GraphicFeatureServer.HandleREST_AddFeaturesOperation (code=17000): Database error: The spatial index grid size is invalid. If the grid is based on a polygon feature, labels are drawn in between the edges of a feature. The point value of the Label Offset must be at least 1/2 the point value of the labels, or the labels will not draw. Therefore, if the area covered by a cell is 5 x 5 meters, then the resolution is 5 meters. ", If this error is encountered while editing in ArcMap, recalculate or modify the grid size of the feature class to accommodate the new feature.

MVP Honored Contributor ‎04-05-2016 02:35 PM. by DavidBollinger. Consider how many grid levels are needed and remember that the database optimizer scans the spatial index table once per grid level. The maximum size any single file ArcGIS 8.x, ArcInfo Workstation and ArcView 3.x can address is 2.147 GB. Anyone have a solution? The grid size is based on the size of the map display in ArcMap. Query the business table to obtain the average feature size. A grid shows reference points on the layout that you can use to position map elements. When working with imaged raster data, there are four types of resolution you may be concerned with: spatial resolution, spectral resolution, temporal resolution, and radiometric resolution. This is the opposite of scale. This requires the use of the Stop Editing function. You can change the size of the grid to allow more or less freedom in positioning map elements when snapping to grid is turned on.

This tool supports multidimensional raster … The top graphic shows a raster of an area at a fine resolution, while the graphic immediately below it shows a raster of the same area with a coarser resolution. In these cases, you may need to experiment with the spatial index, trying different cell sizes and different grid-level configurations. But in an effort to figure out how and why I ended up with invalid grid size, I thought I would start with the actual grid size. The spatial index is used to improve performance when working with data in file geodatabases or ArcSDE geodatabases. A new feature class, Arenac_grid_index is created and, if ArcMap is open, added to your active data frame. Keep in mind that the default size of 1,000 is specified in the units of the feature class's coordinate system. This tutorial describes how to use the fishnet, clip, and optionally the buffer tools in ArcGIS 10 to generate a regularly-spaced grid of sampling points inside a polygon layer. Place a grid that expresses location in geographic coordinates (degrees of latitude and longitude) by choosing the graticule type. Enter 6.25 for width and 7.5 for height of the index feature (polygon). To create a surface grid, you will need a shapefile or a table that contains X, Y, and Z values. ; Click the Reference Grid option in Grids and Graticules Wizard. To learn how to delete features, see Deleting a feature. 0. The spatial index grid size is invalid. If you have ArcGIS, you can easily create a surface grid using ArcMap.

A grid and/or a graticule is created in the ArcMap Layout view, but the labels for the grid will not draw. Grid cell size impacts the size of the spatial index table. The spatial index grid size is invalid. How to create an empty ESRI GRID file (ASC) based on the size of "Based polygon" with cell size 10? The level of detail (of features/phenomena) represented by a raster is often dependent on the cell (pixel) size, or spatial resolution, of the raster.The cell must be small enough to capture the required detail but large enough so computer storage and analysis can be performed efficiently. If you attempt to perform an edit that will result in the new feature being spread across too many spatial index grids, a message appears indicating the spatial index grid size is invalid, and your edit fails. This question needs details or clarity. The spatial index grid size is invalid. Step 1. For example, consider a grid, shown to the left. Unlike the Cell size setting in the analysis environment, the resolution altering tools are applied only to the resultant raster. Please rate your online support experience with Esri's Support website. This helps size the spatial index table suitably and reduces the amount of processing, because fewer candidate feature IDs must be evaluated against the feature table. The following SQL statement gets the average feature size for a feature service in Oracle: Design the spatial table around spatial data categories such as type, geometry size, and distribution. Often, a single grid level is the best solution for a feature class despite the notion of distributing geometries evenly across many grid levels to minimize the spatial index entries. The label text is taken from the Source field. ; Click the New Grid button. [CustomLineLayer01]. It is not currently accepting answers. The cell size at which the output raster will be created. Tuning depends on the structure of the spatial data. Target for ArcGIS enables you to grid shape files, event layers and table files.
