Finding Vector data that is in the area of a specific value of Raster data
Hiking & ActivitiesDigging Deep: Finding Vector Gold Inside Raster Data Okay, so you’re working with maps and GIS, right? You’ve got your raster data – think of it like a digital photo, a grid of values showing things like elevation or forest type. Then you have vector data: these are your points, lines, and polygons representing actual
How to find lowest elevation change using raster data and w.r.t muliple polygons
Hiking & ActivitiesFinding the Flattest Spots: A Guide to Elevation Change Analysis with Polygons Ever needed to find the most level ground within a specific area? Maybe you’re planning a bike trail, assessing flood risk, or figuring out the best place to build. Whatever the reason, understanding elevation changes across different zones is a common challenge in
Shapely : cascaded_union seems to return too many polygons
Hiking & ActivitiesShapely’s cascaded_union: Why You Might Be Seeing More Polygons Than You Expect Shapely, that awesome Python library for playing around with geometric shapes, can be a real lifesaver. It lets you do all sorts of cool things, like figuring out areas, finding intersections, and, of course, combining shapes. That’s where cascaded_union (now, unary_union) comes in.
Is there a way of getting map subsections referenced on main map in qgis?
Hiking & ActivitiesZooming In: Referencing Map Subsections on Your Main Map in QGIS Ever wanted to really spotlight a specific area on your QGIS map? Maybe you’re showcasing different districts in a city or highlighting unique geological features. Whatever the reason, QGIS offers some neat tricks to reference those smaller subsections right on your main map. Let’s
Examining each connected pixel to select its neighbors to separate clusters using ArcGIS for Desktop?
Hiking & ActivitiesDigging into Raster Data: Separating Clusters Pixel by Pixel in ArcGIS Ever stared at a raster dataset and felt like you were looking at a jumbled mess of pixels? I know I have. But hidden within that mess are often valuable patterns and groupings just waiting to be discovered. One common task is separating these
How to calculate the shared area between a raster and a shapefile in ArcGIS 10?
Hiking & ActivitiesDecoding Overlap: Finding Common Ground Between Rasters and Shapefiles in ArcGIS Pro Ever wondered how much of a forest is actually within a protected area, or how much urban sprawl eats into farmland? That’s where calculating the shared area between different types of geospatial data comes in handy. In ArcGIS Pro, figuring out the overlap
