Vector layer reprojection

Last time we showed how to give a coordinate system to a loaded vector layer. What if we want to

It is common that no coordinate system is associated with the loaded raster or vector data. The lack of a

Often we want to find the bounding box of our vector layer. How do we do that in R? We

The rgeos library contains many tools for analyzing vector layers. The two most important functions are gIntersects and gIntersection. The

Buforowanie jest jednym z podstawowych narzędzi GIS używanym w analizach przestrzennych. Ale jak to zrobić w R? Wczytajmy najpierw warstwę

Often in image processing, one wishes to assign a single unique number to a particular range of raster values, for

Zonal statistics is a useful tool that allows you to determine arbitrary statistics from raster pixels that intersect with, for

Analyzes on spatial data cannot be performed without loading them into R. The library rgdal is used for this purpose.

The number of packages we can use in our studies is huge. Some packages duplicate their own functionality. I recommend
