rose Joliewelcome to all our expensive faculty college students, many faculty college students are questioning regarding the retort to this question coordinate system – $region provides NULL for some polygons in QGIS’s Field Calculator. we’re fortunate to secure you as soon as extra on the positioning recipes gist we welcome you and proffer you contemporary questions and options.
coordinate system – $region provides NULL for some polygons in QGIS’s Field Calculator
I’ve the map of Cambodia(map) and the financial land concessions(elc). In looking for the harmony of locality coated by land concesions, I necessity the region variable. But after I create the variable as $region, there are some entries which are NULL – it’s the illustration for each layers. I’ve tried ‘pickle geometries.’ It largely mounted the issue for elc layer however quiet is NULL for one layer as following. Smaller piece and the larger piece are seperate entries however region is calculated just for the diminutive region.
The region calculation loom isn’t mounted in any respect for the elc layer. What is the following factor I might attempt to pickle this downside?
I’m following the steps from this hyperlink:
