For what it's worth, calling the GDAL buffervectors tool from R via the OSGEO4W shell with something like the code below is fast (even with the original data) and may be useful in some cases: system("C:/OSGeo4W/OSGeo4W.bat qgis_process-qgis run gdal:buffervectors --distance_units...
# The name that the user will see in the toolbox self.name='Wedge Buffer' # The branch of the toolbox under which the algorithm will appear self.group='Wedge Buffer' # We add the input vector layer. It can have any kind of geometry ...
Focusing on a Chilean biodiversity hotspot, we assessed the landscape in terms of existing woody vegetation elements and proposed a buffer strip and hedgerow network. We used spatial analysis based on Google Earth imagery and QGIS, field surveys, seven guidelines linked to prioritization criteria and...
Affected QGIS version: 3.4.2 Redmine category:map_toolsEnable labeling on a layer Use the "change label" tool from the label toolbar, creating a data storage auxiliary DB. In the change label properties dialog, there are some buffer related options (size, color) that you can change. Modify...
I am getting a rather large difference comparing turf.buffer to the result of a buffer generated in GIS software. The GIS buffer was projected in MD state plane, then queried to a geoJson feature using SR 4326 via esri's REST api. Using a leaflet measure tool to ground truth, the GIS...
Buffer zone analysis was performed upon the overlay of the rivers before a buffered shapefile was created; the shapefile was used as a clipping tool to determine the classes within the buffer zone and their respective areas. The buffer field was set at 60 m as stated in the Environmental Poli...
The modes of interaction (e.g., mouse and touch) between maps and users affect the effectiveness and efficiency of transmitting cartographic information. Recent advances in eye tracking technology have made eye trackers lighter, cheaper and more accurate
