Slope calculations appear to be 90 degrees off in ArcGIS 3D Analyst?
Hiking & ActivitiesHow does ArcGIS calculate slope? The slope value is calculated by measuring the angle between topographic surface and the referenced datum. Both planar and geodesic computations are performed using a 3 by 3 cell neighborhood (moving window). For each neighborhood, if the processing (center) cell is NoData, the output is NoData. Can a slope be
R, Using a shapefile to extract values from a Landsat Image
Hiking & ActivitiesHow to extract raster values to polygon in R? These are the main steps in the process: Load raster and polygon data. Mask and crop the raster layer. Subset the multipolygon feature collection. Extract the underlying raster values for each feature in the polygon layer. How to extract raster values at points in R?
How to show on Leaflet: WMS on top of OpenMapTiles (vector PBF)?
Hiking & ActivitiesDoes leaflet support vector tiles? Leaflet doesn’t support vector tiles by default. For basemaps, it is recommended to use it with traditional raster tiles (Mercator XYZ). Such tiles can be generated on demand for any of the GL styles with the open-source server software called TileServer GL. What is WMS tile layer? The Web-Map Service

What does unexpected identifier mean? “Unexpected identifier” means that you have a variable you’re trying to
Deciding on classification method and number of classes for mean temperature
Hiking & ActivitiesHow many classes are typically best for mapping a data set? If you want to be safe, make a map with 3–7 data classes. When should I use natural breaks classification? The natural breaks (or Jenks) classification method utilizes an algorithm to group values in classes that are separated by distinct break points. This method
Setting Zero values back to NULL
Hiking & ActivitiesHow do I replace 0 with null in tableau? The Tableau ZN function only works for numeric fields and changes Null to 0. That’s the only use for ZN: to change Null numbers to zero. It works for both row level and aggregate numbers. This function will error if using it with String, Date or
