Hi I have been testing building models in Processing and I have some additional thoughts.
- I would like to see better documentation, including descriptions and examples, including images where applicable, for all algorithms. For quite a few algorithms, there seems to be no documentation in the tool at all. - Not exclusively related to Processing, but support for reading data from LDAP would be valuable. - How about support for duplicating a model in the model list? I can imagine that I would like to create similar models somewhere down the road. - It should be possible to drop files outside of QGIS directly on a model and use it as input. - In the algortihm for dropping attributes, it seems that I manually have to enter the attributes to remove. The drop down list is empty. Is this intended? I would prefer a list/window where I can select one or more attributes to drop. - When writing to a SHP file that already exists, I get a Python error. When I remove the file and run the model again, it works as expected. - When writing to an excel file and the file already exists from a previous model run, all of the featres are replaced. There should be an option for how to handle this case. Replace the file, truncate, add features to the existnig content. - How do I write to multiple data sets in the same model? For me, it is not uncommon that I want to create for example SHP and excel output in the same job, but I don´t see how to create more than one output file. - When I write features with a geometry to an excel file, I get a Python error and the result is emty. If I drop the geometries in the model, it works as expected. Of course, excel files can´t contain geometry, but when writing to file formats that don´t support geometry, the geometry should be ignored and not cause an error. - I would like to see support for using a template for styling the exel files created with a model. For example fonts, locking the first row and so on. - The algorithm for calculating the shortest path onlys seems to allow selecting start and end point manually from the map. In some cases, I have a large table with coordinates for start and end points and I would like to be able to use these attributes instead, creating one route for each combination of points. Perhaps this would be good candicate for using OpenCL? Any thoughts?
