How to plot contours on a map with ggplot2 when data is on an irregular grid? What you should do is wait a bit on SO to see if an answer emerges and if not, flag your question with a request to migrate it here. |

How to combine stacked polygons within a shapefile? It used to be possible just to union a layer with itself. Has that changed? |

What's regular blocking arrangement ? (GDAL) Until this question showed up, the top Google hit for the error message text was at trac.osgeo.org/gdal/wiki/frmts_wtkraster.html. Section 3.2 looks like the relevant one (although its answer may be unsatisfactory: "the driver is under development, and will work with more raster arrangements ASAP"). |

Why do I need to know what “endianness” is? Do you plan to write low-level code to read shapefiles or rasters at the binary level? You might be interested in a closely related thread, Oddities in the Shapefile Technical Specification. |

“GIS” Mapping on Monument - Scaling +1 It's always fun to see GIS used for analyzing things at unexpected scales--microchips, paintings, the cosmos, and now building materials! |

How to find out what projection my data is using? Please search our site for solutions. If they don't help, you will need to supply more detailed information: "off" and "skewed" are merely suggestive, whereas quantitative information about the errors can help solve the problem. |

How does QGIS calculate the area of a polygon? If you will be comparing these implementations in any way, be aware that the areas could disagree for reasons other than the area-computation algorithm. For instance, the GISes may internally change coordinates in order to fit within an area of interest or predefined project boundaries. Some GISes use floating point coordinates and others use (scaled) integer coordinates. Also, it would be practically meaningless to do timing comparisons unless you could identify and control for various overhead operations. So in the end, given no comparison of time or accuracy will be valid, what's the point? |
