Creating Vector layer from selected features with PyQGIS
Hiking & ActivitiesSlicing and Dicing GIS Data: How to Create Vector Layers from Selected Features with PyQGIS Ever felt like you’re drowning in GIS data? You’ve got this massive dataset, but you only need a tiny, specific piece of it. Maybe you’re after all the parcels zoned for commercial use, or perhaps just the highways classified as
QGIS swaps(?) attribute tables of PostGIS layers
Hiking & ActivitiesQGIS and PostGIS: When Your Attribute Tables Go Haywire (and How to Fix It!) QGIS and PostGIS – they’re like peanut butter and jelly for geospatial pros. QGIS, that trusty open-source GIS, plays incredibly well with PostGIS, the spatial whiz kid extension for the PostgreSQL database. Together, they give you serious power for managing and
Tools to identify shape of polygon?
Hiking & ActivitiesDecoding Polygons: More Than Just Shapes, They’re Everywhere! Polygons. We’re talking about those closed shapes made of straight lines – the kinds you probably haven’t thought about since high school geometry. But guess what? They’re everywhere! From mapping out property lines to helping robots “see,” understanding polygon shapes is seriously important stuff. And luckily, we’ve
Calculating Accuracy Assessment in QGIS?
Hiking & ActivitiesCalculating Accuracy Assessment in QGIS: Making Sure Your Map Matches Reality So, you’ve created a classified map using satellite imagery or aerial photos in QGIS. Great! But how do you really know if it’s any good? That’s where accuracy assessment comes in. Think of it as a reality check for your map, a way to
Geometry checker not removing overlap between features
Hiking & ActivitiesGeometry Checker Not Removing Overlap Between Features: What’s Going On? Let’s face it: in the GIS world, data accuracy is king. You can’t make good decisions with bad data, right? And one of the sneakiest culprits messing with our data? Overlapping features, especially when we’re talking about polygons. These overlaps can throw off everything from
How to enable tracing in QGIS 3 beyond applications for adding polygon purposes?
Hiking & ActivitiesQGIS Tracing: Ditch the Basic Polygons and Level Up! QGIS, that trusty open-source GIS powerhouse, is way more than just a tool for slapping together some polygons. Sure, everyone knows you can trace, but the real magic lies in pushing those tracing capabilities to the limit. We’re talking next-level efficiency and pinpoint accuracy. So, ditch
