<span style="font-family: 'times new roman', times;">Hey all</span>
</p>
<p style="margin: 0;">
<span style="font-family: 'times new roman', times;"> </span>
</p>
<p style="margin: 0;">
<span style="font-family: 'times new roman', times;">Thank you for responding to my question about geographic coordinates. It's a part of a continouing quest of accessing shapefiles and paint em' to the screen. It's going well, and I'm currently trying out, if my code works as it's supposed to. I've been to the osgeo pages with the purpose of scrutinizing overall 'standards' that relates to GIS, Geography, Projections etc, to conform my work to updated standards. I've shyed away though, becourse it appears to be very formal documents that takes an oath to download .. never mind, I've probably got something wrong somewhere. </span>
</p>
<p style="margin: 0;">
<span style="font-family: 'times new roman', times;">I díd hope, that shapefiles was a solid standard, but I havn't got far before meeting one that doesn't execute in my code. It's one that contains polygon-z data, and it errs exactly where it reaches the end, had it been polygon-m file. I'll set up some error-redirection of the code to conform to this particular type of error, but .. how much malformed implementation can I expect to meet? se note*</span>

The .prj file doesn't seem to comply to any standard. Atleast, I've got two different types on my 
<span style="font-size: 18px;">pc</span>
. How many different types can I expect? I'll be able to handle the two I've met so far, so it's no big deal for now.
</span>
</span>
</p>
<p style="margin: 0;">
<span style="font-family: 'times new roman', times;">As for the attribute .dbf file, I did start out with a standard that didn't match the first file I tried it on, but it wasn't hard to redo it. I look forward to the worst though ...</span>

<p style="margin: 0;">
<span style="font-family: 'times new roman', times;">Setting out to try to combine the files is somewhat doomed to fail a lot on the basis I noted above. I would appreciate any suggestion as to what standards to aim at, or comments on what hurdles to expect else</span>

note* the funny thing is, that I exactly knows what goes on in the mind of the person that has made the wrong implementation: The order that's in your head says x,y (ordinary contents) then x.y.z (conceptual z cont) then x,y,z,m (
<span>conceptual </span>
m cont). Esri has it x,y  .. x,y,m  (for m-cont) and  x,y,z,m (for z cont).
