Calculating distance and/or time taken to travel from population centre to nearest hospital in QGIS Did you look into anita graser examples of pgrouting. Take also a look into [GRASS network functions] (jcastellssala.wordpress.com/2012/05/07/…). |

Split polygons and extract points Separating the polygons in separate files would mean that you would need to merge them back later right? Do you have your data in shapefile? I would try katahdin suggestion first. Install Postgresql\postgis and put your data there. With Postgis spatial index QGIS will decide better what to draw and won't care about the rest. Also, In QGIS you might want to set Scale dependent rendering for your layer, for instance to draw points only if you zoom to the level of one polygon. That will make rendering the full zoom faster. |

How calculate areas between certain contour lines in qgis? How about you create a DEM from your contour lines? After that you could reclass your raster in the desired elevation levels, and then calculate the area (n_of_ pixes * pixel_size²) for each class. |

how separate Mixed classes Hello Nora, welcome to gis.stackexchange! Could you please edit your question and explain a bit more of your problem. For instance, how is africacover data organized. Are you saying that, in an attribute, you have both "6R" values and "2H/6R" and you want to select all features having "6R" even if it's mixed with other? |

How to make digitization more detailed afterwards with QGIS? Maybe another approach, isolate both polygons in a shapefile and merge them (give polygon 2 attributes). Make sure you have no holes in the resulting polygon. Use polygons to lines on polygon 1 to convert it to lines. Then use union to cut your bigger polygon in two, or use Difference to erase polygon 1 area. |

How to make digitization more detailed afterwards with QGIS? In the snapping options set the Avoid intersection to that layer. Then, when digitalizing the second polygon, near the border, just draw simple lines inside the first polygon. In the end QGIS will erase the overlapping part. |

Capitalizing The First Letter Of Each Word In Attribute Field Take a look into my Edit, in your especific case, it will be: value = <BLD_NAME>.title() Notice that Python is case sensitive. Also, title() is not a function but a method of the class string, that's why the syntax is string.title() |

Help in GRASS/QGIS/Python I think that is a totally different question. You should post a new question for that. Very short answer, fid is the feature ID. |

How do I find vector line bearing in QGIS or GRASS? Depending on the quantity of line segments, you could use this very simple (but with some manual work) approach: - In QGIS select the desired line segments and copy them; - Paste it to any text editor, and you will have your features in WKT (Now comes the bad part) - Now you can edit the text to transform it into a csv to import into a spreadsheet. |

How to represent two fields of the same states or district layer using different color borders and fills in QGIS? Not really... It must be something related to your data, since I had no problems with it, and you already had problems before. The problem seams to start when you query the "political" field, right? |
