Thanks Jim! That was the problem. I went back and adjusted all the field names by removing the spaces between and was able to load the data without any problem :)
There are two options deppending on your .xyz datasets: 1) .xyz datasets are in grid structure - the easy way Since GDAL supports .xyz files - http://www.gdal.org/frmt_xyz.html you can use the: GDAL/OGR -> GDAL: Import Raster module. That module supports multifiles selection so it'll do the job. The target cellsize is automaticaly derived from ...
Are you sure that the original "initialDEM.adf" is indeed in the EPSG:31370 coordinate system? Instead of importing with the "-o" flag, try to first create a new region that matches the import DEM by running: r.in.gdal -c input="initialDEM.adf" location="belgium_lambert" Then rerun r.in.gdal without the "-o" flag. BTW, what are you trying to do in the ...
Tom Hengl told me this: Set the 'check.module.exists = FALSE' and 'warn=FALSE' -> this usually does the trick (http://www.rdocumentation.org/packages/RSAGA/functions/rsaga.geoprocessor). And Alexander Brenning told me that: did you notice the warning message, Warning message: In rsaga.geoprocessor(lib, module, param = list(h = ""), env = env, : This ...
I use this free software, Spatial Data Manager. I found that it is the only free software that can load spatial data directly between the major RDBMS. You can filter your data during the export operation. Cheers.
None of these functions return a colored image, black or otherwise. This library(raster) s <-raster("random.TIF") s Returns a RasterLayer object (or perhaps a RasterBrick if there are multiple layers in "random.TIF"). This class (type of object) is defined in the raster package. You can visualize it with plot(s) This library(rgdal) x <- ...
As @Jeffrey states, readOGR from the rgdal library imports a CRS if there is one embedded in the shapefile. You can check by (example using a shp I've been playing with): proj4string(india) # from the sp package #  "+proj=longlat +datum=WGS84 +no_defs +ellps=WGS84 +towgs84=0,0,0" If this returns NA you can specify a CRS with: proj4string(india) <- ...
I think that you have to configure postGIS library as extension in your database. Here an example.
I would suggest reading and plotting the data separately. Since you are likely reading different feature classes (points, lines, polys) it will be difficult to define the plotting symbology in a function. However, given your question here is an example that illustrates translating your workflow into a function. The example function does not limit the ...
