I use the process on a postgis DB, but Shapefiles are also capable of having tabular data without geometries attached. However I do not know how you would create such a file (easily) from an existing geometry-less layer. Maybe something like this: http://gis.stackexchange.com/questions/327/how-can

Hi, Matthias, what kind of format can this file be? This is not the first time I see MapInfo user asking about this feature. I personnaly had last week to add geometries to features that were in a tabular file (csv) and couldn't find how to do this except giving an unique ID to the table data, and

Hi, IIRC you can use the "add part" tool to create geometries for existing objects. Just use the attribute table to select the proper object and then digitize with the add part tool. Of course the selected layer has to be capable of saving geomtries in the format you like (i.e. you cannot geometri

Hi! Martin is right. This is a piece of cake in MapInfo and a very useful work flow. The suggested method requires that you look up the object in the table and then copy its uid to the created object. This is an unefficient method. I have recently struggled to do the same in ArcGIS which proved to

Probably the easiest way to do this would be a join - so if you made me do this I would do: 1. Create a layer (say a shapefile) with a point and a unique ID. 2. Make sure that Unique ID is reflected in your tabular data (point 1 has a corresponding '1' in the tabular data or a point of "Water P

Hi, I'm after your suggestions for the best work flow for adding spatial data to existing tabular data. Say we have a tabular list of playground equipment - I want to associate a point object with each row in the list - so I end up with spatial and attribute data in the one table. I used to do
