I would eliminate the duplication before the merge, then address this in a couple of steps. Join File2 to File1 (Right-click File1 in the table of contents, choose Joins and Relates/ Join, Join attributes from a table. Base the join on Column C. The table to join to this layer will be File2, and the field to base the join on will be Column D. Choose Keep ...

The following script can do what you are asking. There are some catches though... This will not change the original feature class, it makes a copy with reordered fields. There is a limit of twenty fields. This could be adjusted by adding more lines of code for each additional field beyond twenty. This is kind of a dirty way of doing things. It isn't ...

There are two possible approaches to the problem, using Intersect or Union. First it would be helpful to understand what the Overlay options you mention actually do. Intersect only returns areas of overlap, Union returns all areas from both layers. It is further worth noting that in ArcGIS you are limited to two input layers per operation unless you have an ...

This is not QGIS but if you don't consider OpenJUMP Plus totally off-topic, then you can do it like this: Create a grid which has some unique ID as an attribute. Open grid layer and building layer as separate layers into a project. Use the Aggregate function of OpenJUMP Plus. Define that ID attribute will be aggregated by the "majority" criteria. ...

You'll need to use periods instead of commas in the arcpy script to denote decimal places in your scale range.

QGIS uses the Douglas-Peucker algorithm (slightly modified to handle closed loop like polygons, I think) and the unit of the tolerance parameter is the same as the unit of the reference system. Points are removed if the distance with the tentative simplified line is smaller than the tolerance.

The tolerance is a threshold that will usually determine the distance in which multiple nodes may be reduced into a single node or more. The documentation says the input for tolerance is a number and FWIW it represents map units from the coordinate reference system (ie, metres).

Intersect your building layer and grid layer (Vector > Geoprocessing Tools > Intersect). The result should be your buildings, cut up wherever they cross a grid line. Those pieces should have both the building id attribute and the grid cell id attribute. Open the attribute table use the Field Calculator to create a new field and calculate the area of each ...

If i got you, your question itself is answering the question. You used A∩B i.e. Intersection symbols so use intersection analysis to separate out common areas, for A∩B run intersection between A and B, for A∩B∩C run intersection between A, B and C- mind intersection operation input can be multiple.Documentation is at here.

The caching tools that exist in the ArcToolbox on Desktop simply make calls to the Caching tools that have been already published on the Server. If your workflow involves updating a cache through these tools, simply call the tools on Desktop, or call the already published tools on the Server. Publishing these tools as their own GP Service introduces an ...

Per @matt wilkie Suggestions, you should use python toolbox (.pyt) instead of a custom (.tbx) toolbox. However with python toolboxes you cannot have models. So if you have any models in your custom toolbox, then you have two options: to export those models to python script tools. to call tools in other toolboxes from within the Python toolbox code Here ...

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.
