Select all columns except geometry using virtual layers












2















Is it possible to select all columns except geometry using virtual layers in QGIS?



For example I have this (simplified) query:



Select *, st_buffer(geometry, 100) From mypolygons


It does not work. It does not buffer at all. But using the (simplified) query as follows does buffer all polygons as intended:



Select id, name, st_buffer(geometry, 100) From mypolygons


Now the issue is, that if I have polygons with a lot of columns I need them to type in all manually. Is there a way to avoid this?

          It does work as intended, and it is only a display issue.



          To make is work, just give a name to the buffered geometry and specify this name as being the spatial column.



          Otherwise, the virtual layer has two geometry columns, the original geometry and the new st_buffer(geometry) and the 1st one is picked-up for display.

                    How to label and detect the document text images

                    Image
                    1 $begingroup$ This is what I mean as document text image: I want to label the texts in image as separate blocks and my model should detect these labels as classes. NOTE: This is how the end result should be like: The labels like Block 1, Block 2, Block 3,.. should be Logo, Title, Date,.. Others, etc. Work done: First approach : I tried to implement this method via Object Detection, it didn't work. It didn't even detect any text. Second approach : Then I tried it using PixelLink. As this model is build for scene text detection, it detected each and every text in the image. But this method can detect multiple lines of text if the threshold values are increased. But I have no idea how do I add labels to the text blocks. PIXEL_CLS_WEIGHT_all_ones = 'PIXEL_CLS_WEIGHT_all_ones' PIXEL_C...

                    Tabula multilinguis Rosettana in Museo Britannico ostenditur. Tabula Rosettana, [1] etiam titulo OGIS 90 agnita, est stela decreto de rebus sacris in Aegypto anno 196 a.C.n. lato inscripta. Tabula iuxta Rosettam Aegypti, urbem in delta Nili et ad oram maris Mediterranei iacentem, anno 1799 a milite Francico reperta est. Inventio stelae, linguis duabus scripturisque tribus inscriptae, eruditis Instituti Aegypti statim nuntiata est; ibi enim iussu imperatoris Napoleonis eruditi omnium scientiarum (sub aegide Commissionis Scientiarum et Artium) properaverant cum expeditione Francica. Qua a Britannis mox debellata, tabula Rosettana Londinium missa hodie apud Museum Britannicum iacet. Textus Graecus cito lectus interpretationi textuum Aegyptiorum (in formis hieroglyphica et demotica expressorum) gradatim adiuvit.
