ModelBuilder: How2 pipe output of Iterate Raster tool into Raster Calculator tool? Why not use arcpy? It would be easier to iterate all the raster by the command ListRasters and do your calculations by the command RasterCalculator. |

Heatmap.js is not displaying on openlayer Yes, but it doesn't return any bugs. |

Raster noise reduction and edge smoothing Hello! If you don't mind, could you send me your contact information? I would like to acknowledge you in my research. Thank! @whuber |

Draw two separate lines from A to B and B to A @Andy R should be fine for me. |

Draw two separate lines from A to B and B to A @whuber Thanks for your suggestions. I was thinking a way to solve this: 1) Define a function DrawArcBetween(Origin, Destination, arc) 2) Define a Hashset<Destination,Origin> 3) If the destination, origin pair can be found in the Hashset, take the negative of the arc. Don't know if there would be simpler way to solve this... |

How to find the minimum extent of a given pixel value of a raster? I did this exactly. Is there any automatic way? I think the raster to polygon algorithm has a step to extract the minimum bounding box of the raster. |

How to find the minimum extent of a given pixel value of a raster? @whuber I saw your solution somewhere else, but still not sure how I can implement your method. Could you show me some more detail of this? |

Iterate features on SpatialPolygonsDataFrame in R Thank you very much! I think this method will greatly accelerate my codes! |

Create Zonal Grid in R I think your approach is very nice. The only concern for me is the smaller rectangles around the edge area. I think for ecological study, it requires almost all the grids to have similar area. |

Create Zonal Grid in R Thanks @whuber, I think my function just works for square grids which I need. Also, what do you man by "padding out the array" for this method? |

Create Zonal Grid in R I think the kronecker product will work and I uploaded my answer. Thank you very much though! |

Create Zonal Grid in R Thanks for your answer @yellowcap. I am wondering if there is anyway to get rid of the double for loop. It could be very slow for a large matrix. |

Raster grid for zonal statistics in R @JeffreyEvans Thank you. I have added another question on how to create zonal grid here gis.stackexchange.com/questions/34895/create-zonal-grid-in-r |

Detect whether there is a spatial polygon in a spatial extent I think it makes sense, my concern is how to perform spatial query in R. |

Detect whether there is a spatial polygon in a spatial extent I will consider it as an extent. So do you have some suggestions on methods? |

Detect whether there is a spatial polygon in a spatial extent I think clipping can do this, but if I have a lot of zones to process? |

Count raster value in a bounding box (spatial extent) is there anyway just perform spatial query rather than cropping the image? Cropping might be very slow for processing. |
