R: data.frame to raster object error Could there be anyway to find the holes in a none manual way? The data in question has 1,900,000 points and it becomes really difficult to sweep through it. Qgis gets very very slow and takes ages just to zoom in once, for example. |

R: data.frame to raster object error Actually now I'm intrigued as to why my grid has holes in it... How would I go on to verify where the holes are? |

R: data.frame to raster object error I have been exploring the interpolation of point data for sometime now. In fact you have answered some of my questions @whuber, thanks. It's just that what I do in R I usually just end up opening in Qgis and continue working it from there. I am looking for ways to do this directly in R. I was in fact just trying to turn my point data to a raster to plot it using the raster package. I'm quite new to GIS and all spatial topics so sorry for sounding so lost sometimes. |

R: data.frame to raster object error I think my confusion si what exactly is a regular grid of points. Could you explain this to me? for example, if the points are all equally spaced but you have "missing points" would the grid become irregular? |

Merging many rasters using Python Alas I dont think that the application supports GDAL virtual formats. We are working on the google earth engine and it's in very early stages of development but thank you, I like the idea a lot. |

Merging many rasters using Python Ok, so I did something like this: ### discard files that are not geotiffs dirList = [item for item in dirList if item[(len(item)-3):(len(item))]=="tif"] ### print to text file thefile = open('filelist.txt', 'w') for item in dirList: print>>thefile, item Ideally I would want to call gdal_merge.py from another script as I find it rather cumbersome to create the *.txt and then gdal_merge -o ... As I mentioned before I'm interested in sharing this, it's not really for me. I would like to use something like gdal_merge.raster_copy( etc ) but I have not got this to work. |

Merging many rasters using Python I would want the script to search in a folder form a list with all image file names: path="C://Julian//EarthEnginedownload//L5_ANNUAL_EVI_2002" dirList=os.listdir(path) and feed that to gdal_merge, how can I properly do this? @Ryan Garnett |

Merging many rasters using Python Sure, this was exactly what I was going to use. Does it make sense to use it for a big big amount of images? |
