You can't sum columns using the Field Calculator (although it would be useful in certain situations). To be able to sum columns and obtain a value, you can use: QGIS function - Basic Statistics (Vector > Analysis Tools > Basic Statistics) QGIS Plugin - GroupStats (Plugins > Manage and Install Plugins) QGIS Plugin - Statist (Plugins > Manage and Install ...

FME does not provide the tools to do this with the available transformers. This solution describes how the coordinate check can be done using python (PythonCaller). It is based on an answer to a question at stackoverflow. This is the proposed procedure: Coordinates are made an attribute A list of candidate coordinates is established and written to disk ...

You can accomplish this task with a variety of the analysis 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. Identity (Analysis) Computes a geometric intersection of the input ...

I've made a script for this task https://github.com/kiselev-dv/QGIS-Processing/blob/attributes_crossjoin/scripts/spatial_cross_join_attributes.py

The Spatial Join geoprocessing tool will do what you're looking for. With the tool parameters something like this Target Features: polygon dataset to which you wish to join attributes. Join Features: polygon dataset from which the attributes will be transferred IF they meet the Match Option (Spatial Relationship). Output Feature Class: feature class to ...

The closest tool to what you describe is the Live Statistics plugin. It can be configured to compute different statistics and shows the results in a status bar in the bottom left corner of the main window

In QGIS, try Settings -> Options, Digitizing tab: Feature creation [x] Reuse last entered attribute values. This works for newly created objects, but not if you fill in data of already existing objects.

Could you make use of the Quick Multi Attribute Edit plugin? You can create a number of points first, select a group of them, and bulk edit common attributes using the plugin.

Unfortunately, I have not found a method for creating SLD files in ArcMap for GeoServer use. There are some alternative app. options: Udig QGIS GeoExplorer GeoServer admin SLD editor

You could try to do a spatial join. You can find the tool in the vector menu or in the processing toolbox. After doing this join you can use the field calculator in order to say that the column X with the date is equal to the column Y that you want to populate.

When you have a record but no geometry it's known as a null geometry. The quick fix while in an Edit Session is to select the record/row in question and use the Replace Geometry tool on the Advanced Editing toolbar. This will allow you to create a point to replace the null. It works on points, lines, and polygons, and can replace both null and exisiting ...

Here's a solution works with lines and polygons but not points (for that see @ChrisW's answer): the Continue Feature tool from Edit Vertices toolbar. (Doesn't help Amy, but maybe someone else later). start editing, open the feature class attribute table select a has-attribute-only record pan/zoom to correct location r-click on map, select Edit Vertices, ...

Use field calculator (Python) on shape field, e.g.: arcpy.Point(1747952,5907660) If you know coordinates of this point. This is extension of original answer. Create a copy of the layer in table of content and and call it 'points'. Select correct point in 'points. Use field calculator (Python) on shape field for record with missing geometry: def ...

I've not tried this personally in this exact situation, but you should theoretically at least be able to add a new point at the correct location (leaving the attributes blank). Then go to the attribute table and select both rows (the newly created point without attributes and the corresponding attribute record without a point). Then go to the Editor ...

If you have X/Y data in your table, export the same table with the new records. Right click this table and "Display X, Y Events". You should have a new file with all your points! Export as needed.

OK, so you basically need to compare each of the records in table 2 against each record in table 1. To me that suggests you are going to need a loop of some sort. You could either use a loop (or nested loops) inside a Custom Transformer, or you could do an alternative type of loop using a list. For the Custom Transformer, check out this FMEpedia example, or ...

I am a bit confused by your image. It looks like you're trying to join two tables. But your resulting table appears to have incorrect values in Field 2. I'm going to assume you're trying to join the two tables based on the ID field. This is a fairly straightforward process in FME. You can use the FeatureMerger Transformer. Connect Table 1 to the ...
