<br><font size=2 face="Courier New">We have a program in the government
domain, MapImage (<i>mapimg</i>), which specializes in reprojection of
raster data, primarily for small-scale applications. You can find it at:
</font><font size=2 color=blue face="Courier New"><u>http://carto-research.er.usgs.gov/projection/acc_proj_data.html</u></font><font size=2 face="Courier New">.</font>
<br>
<br><font size=2 face="Courier New">It may work for what you are trying
to accomplish. There is a User's Guide available as well. We are very close
to a new release (version 2) with a few more features. If <i>mapimg</i>
looks like it will help you, we will be happy to give you a pre-release
beta version to try.</font>
<br>
<br><font size=2 face="Courier New">We hope to publish a full paper soon
on the details but, in the meantime, in addition to the user's guide, you
can check out this abstract and presentation from Auto-Carto 2005: </font><font size=2 color=blue face="Courier New"><u>http://carto-research.er.usgs.gov/projection/pdf/abstractMapimgAutoCarto.pdf</u></font><font size=2 face="Courier New">,

<br><font size=2><tt>Alright,<br>
<br>
last time I was looking at vectors. and ogr2ogr -a_srs WGS84 dest src <br>
worked well for me<br>
<br>
Now I would like to take a raster of the bellow characters and bring it
<br>
into the same layer format. I have tried various things with <br>
gdal_translate, proj/invproj, but I don't think I actualy understand <br>
what I'm trying to do (aka I give up). Although I have successfully <br>
taken a directory of 8 *.adf files (the DEM I would like to import) and
<br>
changed it to a GTIFF. Now if I could reproject it (in the same or <br>
different step) would be nice.<br>
<br>
My understanding is that I want to move catesian data (1) to <br>
cartographic data (2)<br>
<br>
My location as seen by GRASS<br>
<br>
LOCATION PROJ_INFO is:<br>
GRASS_INFO_ERROR(10270,2): name: Lat/Lon<br>
GRASS_INFO_ERROR(10270,2): proj: ll<br>
GRASS_INFO_ERROR(10270,2): datum: wgs84<br>
GRASS_INFO_ERROR(10270,2): a: 6378137<br>
GRASS_INFO_ERROR(10270,2): es: 0.0066943800<br>
GRASS_INFO_ERROR(10270,2): no_defs: defined<br>
GRASS_INFO_ERROR(10270,2):<br>
<br>
Data to bring in seen by GRASS<br>
<br>
Dataset PROJ_INFO is:<br>
GRASS_INFO_ERROR(10270,2): name: Universe Transverse Mercator<br>
GRASS_INFO_ERROR(10270,2): proj: utm<br>
GRASS_INFO_ERROR(10270,2): datum: nad83<br>
GRASS_INFO_ERROR(10270,2): a: 6378137<br>
GRASS_INFO_ERROR(10270,2): es: 0.0066943800<br>
GRASS_INFO_ERROR(10270,2): zone: 18<br>
GRASS_INFO_ERROR(10270,2): no_defs: defined<br>
GRASS_INFO_ERROR(10270,2):<br>
<br>
(data in Ontario MNR DEM in *.adf format)<br>
<br>
I have tried<br>
<br>
(inv)proj +ellps=WGS84 src<br>
<br>
but think I'm missing something. Seemed like a good idea.<br>
<br>
I have also tried (as per docs and tutorials) to create a new location
<br>
to import raster to, then turn around and try to reproject the data from
<br>
one location to another. I missed something along the way cause that <br>
never seemed to work.<br>
<br>
I'm sure there is a simple solution.-<br>
