How can I setup plot areas to be identical in attribute table and map. In map and in attribute table I'm using the same " $area " designator. What's more interesting, the area of smaller plot is higher than the bigger one..

    How did you calculate AREA field? Did you edit your plots after you did this? And using $area as lable

  • Qgis were asking me to save changes in plots shp file, so i think i did change them. AREA field is calculated using New Field (named: AREA, type "decimal (real)" and 5 digit number with 1 precision) and by choosing 1.2 AREA$area in Filed Calculator.

  • I think it has something in common with CRS and projection. In Project Properties -> Variables there are two infos : project CRS is "EPSG 2178" and project elipsoid is "EPSG7019" . I cant set the same setting in project properties and layer properties, simply can't find them in rollout menu.

OK, the problem was, that i first created new field in attribute panel and then put a new formula ($area) to that field using field calculator. It works fine when You create new field using directly field calculator.
