I have a Shapefile file with more than 2,000 elements, with its extensive table of attributes, and I have made a model file, through the Atlas, where a map appears with a zoom of each element and a set of attributes that change, as that each of the elements is represented.
1 - How to reduce the size of the output pdf? For each element, your pdf weighs about 10 MB, since each element is represented on an orthophoto, but I would like to reduce the output quality.
2 - I would like to generate a single output pdf with a specific set of elements, that is, for example, a single pdf with the files that go between 30 and 50. I interpret that it should be done by code in the Atlas section / Output / Output expression file / in the epsilon, in the expression section, there I imagine it can be automated but I don't know how.
