[clug] SPLAT Signal Propagation, Loss, And Terrain analysis tool [SEC=PERSONAL]

[Roppola, Antti]

Hi Keith,

The link is a request to send the Topo250 WMS service's
"GetCapabilities" in an XML document. It's designed to help a WMS aware
tool identify which layers can be requested via other methods like
"GetMap". Here's an example where I've manually constrcted a map
request:

http://mapconnect.ga.gov.au/wmsconnector/com.esri.wms.Esrimap?Version=1.
1.1&Request=getMap&Service=WMS&Servicename=GDA94_MapConnect_SDE_250kmap_
WMS&layers=MajorRoads&srs=epsg:4326&bbox=144,-37,153,-30&width=600&heigh
t=600&format=image/png
(as you can see, there's no pesky licenses to agree to and it's pretty
fast)

Here's the same WMS service included in the OpenLayer sample I showed at
CLUG a couple of momths back. It's not quite working, I ran out of lunch
time so I'll have a tinker later on, but "view source" gives you a feel
for how the Geoscience WMS data source is used with OpenLayers:
http://www.elder-gods.net/hastur/foss4g2009/openlayers/ga.html

As you identify, you can also access the Topo250 data in a range of
other formats including downloadable ESRI Shapefiles. What format is
most appropriate will depend on what tools you want to use to overlay
your data. WMS is great if you don't want to download all the data and
want to include other WMS sources in your mash-up, Shape is better if
you want something that isn't network dependant. Shape is compatible
with most desktop GIS software.

Cheers,

Antti

Hi Antti,

The Digital Elevation Topography Models are from
<http://www2.jpl.nasa.gov/srtm/> but downloaded
from<http://dds.cr.usgs.gov/srtm/version2_1/SRTM3/>

I couldn't open the link in your second para but this is a list of
available formats from mapconnect
<http://mapconnect.ga.gov.au/MapConnect/?site=250K&accept_agreement=on>
the default is ESRI Shapefile.

Can you suggest which of the above formats I might try?

I will read-up on Web Map Service from Geoscience Australia
unfortunately the mapconnect XML file would not display with firefox???

Thanks for your help, if I may I will ask further questions when I've
done some more reading.
