My problem is this, when I read the data into R, my polygon types (e.g. agricultural, anthropogenic) are being considered as levels of the factor "layer" rather than factors in and of themselves. I need agricultural land cover to be a factor so that I can calcula...
How to Run an Intersect in QGIS For QGIS 3, you can find it in the Vector | Geoprocessing Tool | Intersection. In both GIS software, the main entries are its inputs and output. But in ArcGIS, you can specify the output type as points, lines, and polygons. In QGIS, you can set i...
You can use the TravelTime Matrix API in two ways: As a standalone API Within our plugins forArcGIS, QGIS or Alteryx Creating matrices with the TravelTime API is done through a credit model. With one matrix credit, you can calculate travel times from one location to up to 2,000 destinat...

If you want to identify which locations fall within a travel time catchment area, and which lie outside this requires a slightly different process. Follow the tutorial below to filter your points and calculate the distance to each. Try our free point in polygon tutorial ...
of which 1.3m have zip/lat/long. i do not have the skill-set or knowledge to make large-scale changes to the data behind the scenes in access or sql, i was hoping what i had was sufficient and tableau could help with the rest. is it possible to use the polygon method if you just...
To use it as a buffered heatmap, you'll need to change the ESRI Shapefile, or you can simply garnish the average polygon centroids and use the metrics that way, or you can be really sophisticated and do buffers from the polygon centroids. The lowest level of pop is Census Block in the...
In QGIS, I often find myself setting up projects with an ellipsoid coordinate system (e.g. WGS84) so that the resulting maps have lat lon scales, etc. Often in these projects I also need to do some calculations in other units (e.g. calculate the sq km of a feature). At present ...
