[Zoo-discuss] ZOO Project with MapServer (WIndows 10)

[MAYANK JASORIA]

I am using ZOO Project 1.5.0 installed using
ZOO-Project-Installer-x64-72.exe.
<https://dl.bintray.com/gfenoy/ZOO-Project/:ZOO-Project-Installer-x64-72.exe.>

For MapServer I followed the instructions to host MapServer on IIS
according to this link: MapServer on IIS
<https://www.google.co.in/url?sa=t&source=web&rct=j&url=http://mapserver.org/installation/iis.html&ved=2ahUKEwjR9ZOD8fjbAhWDV30KHRNYBzIQFjAAegQIABAB&usg=AOvVaw15lO5k1CjwU6iBUaqSTbzK>
(MapServer
version 7.0.7).

As for the data that I want to process, I was initially under the
impression that it should be some result from WMS GetMap request as GDAL
does list image/png, image/geotiff etc. as a valid input accepting
rasters (MapServer
input formats <http://mapserver.org/input/index.html>). However, it does
make sense that I needed the data from a WFS GetFeature request, unlike my
previous thoughts. I also tested the geotiff8 input for multiple cases and
found that after a point it started to fail miserably, giving outputs which
were very far off from the actual data. Sorry for this confusion, I'm
pretty new to this.

Now when I tried WFS GetFeatures, it seems to work fine for GML 3. However,
if I try to pass a shapefile, I see the same errors which I reported for
other formats. I tried this on a script that I wrote instead of HelloPy
though as it is easier to try the returned GetMap URL (from MapServer)
here. Also, I found that the KML error was because of an error on my part.

There is another thing though. Now the images that I am getting are getting
resized instead of maintaining the actual shape which it should, to align
properly on a map. I am not sure of the reason though I guess it is because
the image is getting resized according to the width and height parameters
in the GetMap request returned from MapServer.

Could you please guide me on the shapefile and image resizing issue?

Thank you very much for your help.
