Dear Roger,
Many thanks for your rapid reply! I guess I was so caught up in the
details of rgdal that I completely failed to see that obvious problem.
I've managed to fix the coordinates, and now rgdal reads the image just
fine.
I'm still searching for a good overview of rgdal or gdal tho
Hi list,
Is there any way to get readOGR() to correctly read
non-ascii character strings from the dbf file? I've
checked and my dbf file correctly displays
names with accents, but once read into R
accents are substituted by wrong symbols.

Dear R-sig-Geo,
I'm trying to get started with rgdal, and not having much luck so far.
I'm running R 2.5.0 on an i386-pc-mingw32 with rgdal 0.5-9 and sp 0.9-14.
For starters, I'd like to read in an .img file created in ArcGIS 9.2. As
you can see below, the file is a global map in geographic c
Hi Stéphane,
For US locations, you might try www.nationalatlas.gov, click on MapMaker (upper
left) and then 'Find' (upper right).
It allows you to search by name of geographic features. I've found some small
ponds by name and state using this.

Dear list,
I have a question, not directly linked to R, but I hope that some people
could help me. I have a paper, where there are some data that I would
like to analyse with spatial tools. In the appendix of the paper, for
each site, there are some data... but I do not have the spatial

Michael,
The plot method for SpatialLinesDataFrame objects resides in package sp,
and questions regarding it are easier noticed on the r-sig-geo mailing
list.
The reason why they are plotted with aspect ratio 1 is that they are
assumed to be spatial (geographical) data, and assume that 1 m nor
