"multi-points" (you can check in the geometry field) behave like single geometries. You can convert from multi-point to points using "multipart to single part" tool, then you can run your "select by location" within a distance. If needed, you can then dissolve the points based on the original ORIG_ID in order to reconstruct the multi-points. The other ...
To do this I would use two tools: Intersect (Analysis): Computes a geometric intersection of the input features. Features or portions of features which overlap in all layers and/or feature classes will be written to the output feature class. then Summary Statistics (Analysis) Calculates summary statistics for field(s) in a table.
Create Mosaic dataset,NOT MOSAIC TO NEW RASTER. Use it as input, it will work as single raster
Try register your VIEW this manner: INSERT INTO views_geometry_columns (view_name, view_geometry, view_rowid, f_table_name, f_geometry_column, read_only) VALUES ('buffer500m', 'geometry', 'ROWID', 'point', 'geom', 1); read_only option boolean 1 for read only VIEW - read_only option boolean 0 for updatable VIEW. In Spatialite Cookbook not consign ...
If you are trying to randomize your original points, you may want to take a look at the Point Randomizer script rather than using the buffer method. It is possible (with a Spatial or 3D Analyst extensions, or an Advanced license) to use the Create Random Points tool and constrain the points to fall on lines. You could take your buffers and intersect them ...
If you create a model in the model builder function, you can see the % completed bar. I like to do this when processing large amounts of data so I can monitor the progress. Results Window should do the same thing but doesn't.
When buffering (among other distance related operations) in a geographic coordinate system, your result may appear or be distorted in 2D because geographic is on a sphere/ellipsoid, not flat. Geographic uses angular degrees for measurement, and a degree of longitude can vary significantly in terms of distance depending on latitude (which is relatively ...
ST_Collect is probably not the function you are looking for, as this simply combines geometries into a geometry collection of some type, and does not actually union/dissolve them. ST_Union, on the other hand, does dissolve overlaps, and assuming polygonal input (which is most probable in conjunction with ST_Buffer and an input table called point), and ...
