QGIS can load geographic data from a CSV file via Layer --> Add Delimited Text Layer. If you would like to load the grid data as polygon, you will have to format the data in the WKT format. Your end result should be something like this wkt|mun_code|... POLYGON ((3145006 371500, 3145006 372000, 3145556 372000, 3145556 371500, 3145006 ...
OK, so I made something like this: It's not beautiful, profesional, not even close to Your example cause I used zebra instead of interior ticks, but maybe this will help you somehow. I used 5 (yes five) grids: In km (EPSG:2180) with border type zebra and 18mm width - black In degrees (4326) with border type zebra and 16mm width - blue (so it covered ...
The solution to this is not in ArcGIS. Unfortunatly, you have to change your region settings in Windows. On Windows 7, the solution is to go to Control Panel, Region and Language, then click on Additional settings... Under Digit Grouping Symbol, just type in a space instead of a comma. Results:
Use spsample with cellsize: pts = spsample(leg, cellsize=c(10000,10000), type="regular") plot(leg) points(pts) check the coordinate spacing: > coordinates(pts)[1:10,] x1 x2 17 244356 4437161 18 254356 4437161 19 264356 4437161 you see the x coordinate going by 10,000 (and if you look later on you'll see the y coordinate does too)
The antimeridian can cause problems; however, you can choose a different prime meridian (I'm sure that, historically, several nations have claimed their own prime meridian). Create a copy of whatever data source you used to generate the routing tables. To each node East of Prime Meridian, subtract 180.0 from its longitude For each node West of Prime ...
Okay, I made the grid in Qgis composer, and added the coordinate labels by hand in Photoshop - meaning I had to measure the lat/long position of each line by hand in Qgis Desktop.... This labeling feature is definately very very buggy. Sorry.
The pattern you observed is related to the order the edge table rows are generated, which is not defined by your query. I don't see how you could repair your queries to meet your expectations. My advice is to keep edges and nodes in distinct tables and join them by id. This is a basic principle with relational databases. If the "centroids" input table is ...
