I am new to this list and hope you can help. <br><br> I have a GeoTif raster file that currently shows "+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs" as its CRS in the Options form in QGIS.<br><br><font face="Arial" size="2">I have the Tiger shapefile that has in the .prj file GEOGCS["GCS_North_American_1983",DATUM["D_North_American_1983",SPHEROID["GRS_1980",6378137,298.257222101]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]]<br>
<br>I have added several vector layers that I have created with QGIS and all have the following in their .prj files.<br>GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137,298.257223563]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]]<br>
<br>I need to be able to get the Tiger data to align with the GeoTif and other layers.<br><br>I tried to export the Tiger file using the Vector / Data Management Tools / Export to new Projection<br><br>I first loaded two Vector layers. First a local layer that was in the desired projection. (a layer that I created ) having the same info in the .prj file as noted above [WGS 1984].<br>
Then I loaded the tiget shapefile layer. <br><br>I selected the Import spacial ref from existing layer<br><br>I tried switching the input and output selections both ways:<br> first I selecting local layers spacial ref system "+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs" as Input <br>
and the Tiger shapefile spacial ref "+proj=longlat +ellps=GRS80 +datum=NAD83 +no_defs" as output<br>This created a set of files <br><br> Then I switched the input and output <br>Both produced the following in the .prj files<br>
<br></font><font face="Arial" size="2">GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137,298.257223563]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]]<br>
GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137,298.257223563]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]]<br>
</font><br><font face="Arial" size="2">IO load any of these with the rest of the layers and zoom extents and get a white screen with a little speck in one corner. That speck is the raster layer and all the layers I created manually.<br>
<br>Please help!<br><br>Thanks<br><br>Chuck<br><br></font>
