deegree

Tests written for

deegree 2.2, arramagong 2.0.1

Test Description last updated

March 2010

Steps

• Click desktop icon "start deegree" which will run "catalina.sh start".

Verify firefox opens a new tab at the page http://localhost:8081/

• Click the service links ("deegree-wms", "deegree-wfs", "deegree-wcs") in top left box ("deegree Web Applications").

Verify they open test pages for WMS, WFS, and WCS. These pages will contain links to

• "GetCapabilities" (for each of the services)
• "Test WMS", "Test WFS" or "Test WCS" (depending on the chosen service)
• a link for the "Generic Client", a client for sending XML requests (http post) to the services.

• Click on "TestW*S"

Verify you get either maps or xml fragments.

• TestWMS will contain some images (results of WMS requests), and links for further KVP requests (http get).
• TestWFS will open a page with several links for WFS requests (KVP). Either one will return XML fragments. There is also a link to the generic client.
• TestWCS will open a page with several links for WCS requests (KVP). Either one will return XML fragments.

• Click the client link ("deegree iGeoPortal") in top left box ("deegree Web Applications").

Verify this will open a new tab with a list of available WebMapContexts. Either one of these links (Utah, SaltLakeCity or Playground) should open a full working portal in this tab. Once the WMC is loaded you may swith to the other WMCs by using the drop down box labled "Theme selection"

• Click on the desktop icon "stop deegree"

Verify the deegree-tomcat process is stopped.

• click any of the links previously used: you will get a "Failed to Connect" message from firefox.
• open a terminal and try ps fax | grep deegree. You should not get any results other than the grep itself.

qgis

FIXME

These instructions are not tested! Just off the top of my head.

open GeoTiff

• where in disk is one?

open PostGIS data

(run the PostGIS test first so that the osm_barcelona DB exists!)

• From the menu: Layer → Add PostGIS Layer ...
• PostgreSQL Connections: [New]

Name: ________ "OpenStreetMap Import" 
Database: ____ "osm_barcelona"

• Click on [Test Connect], with luck you will get a message that the connection to the database was successful.
• Click [Ok] to close the New Database window.
• Click on [Connect] in the top left of the Add PostGIS Table window. You should see a listing of tables come up.
• Click on all of the table names to highlight them.
• Click on [Add] at the bottom.
• After some moments you should see the data displayed in the main map canvas.
• Zoom, pan, query as you like.

This should at least prove to you that the database is correctly populated and running.

open shapefile

• where on disk is one?
• From the menu: Layer → Add Vector Layer ...

Do not select New Vector Layer ... (that's for creating new data, not opening existing data)

• Dataset: [Browse]

? where on disc ?

• Ctrl-click on each of the *.shp files in that directory, then click [Open] and finally [Ok]
• After some momements you should see the data displayed in the main map canvas.
• Because the some of the shapefiles use a different map projection than the PostGIS database, things may not line up exactly. In the Settings → Projection Properties, Coordinate Reference System tab, you can tick the [•] Enable 'on the fly' CRS transformation box to overlay them. Be warned that this is computationally expensive and the layer may need to have its CRS set manually.
• Zoom, pan, query as you like. Drag layer names up and down in the left-pane list to change their position in the stack.

open OSM data

• need to enable plugin?
• open /usr/local/share/osm/Barcelona.osm.bz2

Test the GRASS plugin

• (it's installed, right?)
• enable in the plugin menu
• open location/mapset → ~/grassdata/spearfish90/PERMANENT

marble

Tested against ver 2.0

• Click on the desktop icon
• If you have used Google Earth before you should be able to figure this one out without much difficulty.
• In the Settings menu select full-screen mode
• Explore ...
• In the bottom-left corner of the program window there is a subtle tab called "Map View". Click on it.
• Select another map (e.g. 'Precipitation (July)')
• Explore some more ...

octave

• Open a terminal
• Start program by typing "octave" at the prompt

% Which way to Barcelona from Sydney?
sydney = [-33.8750 151.2005]
barcelona = [41+23/60 2+11/60]

dirn = azimuth(sydney, barcelona);
deg_symb = 176;
disp(['Heading: ' num2str(dirn) deg_symb])

% How far's the trip? (roughly!)
system('proj -le')
wgs84_a = 6378137.0  % major radius of the Earth, in meters
dist_deg = distance(sydney, barcelona)
dist_meters = pi * wgs84_a * (dist_deg / 360.0)
disp(['Distance: ' num2str(dist_meters / 1000) ' km'])

Type "exit" to quit.

opencpn

Activate data

• Open a terminal
• Type "opencpn_noaa_agreement.sh" at the prompt

Run program

(assuming your GPS is not plugged in and gpsd is not running)

• Double click the OpenCPN icon on the desktop or type "opencpn" at a terminal
• Left-click recenters the view
• Left-click-drag pans the view
• Mouse-wheel zooms in/out
• The blue bars in the bottom show previews of overlapping maps and clicking on them switches to them.

More details in the on-disc help page

and specifically the Getting Started help page.

gpsdrive

• (copied from install_gpsdrive.sh)
• More details in the on-disc help page

Testing

If no GPS is plugged in

• Double click on the GpsDrive desktop icon
• You should see a map of downtown Sydney, after about 10 seconds a waypoint marker for the Convention Centre should appear.
• Set the map scale to 1:10,000 either by dragging the slider at the bottom or by using the +,- buttons (not magnifying glass)
• Enter Explore Mode by pressing the "e" key or in the Map Control button.
• Use the arrow keys or left mouse button to move off screen.
• Right click to set destination and leave Explore Mode

Downloading maps

• Change the scale setting to 1:1,000,000 you should see a continental map
• Enter Explore Mode again ("e") and left click on the great barrier reef
• Options -> Map -> Download
  • Map source: NASA LANDSAT, Scale: 1:500,000, [Download Map]
  • When download is complete click [ok] then change the preferred scale slider to 1:500,000
  • This will be of more use in remote areas.
• Explore to the coast, click on an airport, headland, or some other conspicuous feature. You might want to use the magnifying glass buttons to zoom in on it better. Use a right click set the target on some other conspicuous feature nearby then demagnify back out.
• Options -> Map -> Download
  • Map source: OpenStreetMap, Scale: 1:150,000, left-click on map to center the green preview over your target and what looks like a populated area.
  • [Download Map]
  • When download is complete click [ok] then change the preferred scale slider to 1:150,000 and you should see a (rather rural) road map. This will be more interesting in built up areas.

Overlay a GPX track

• In the ~/.gpsdrive/tracks/ directory you will find australia.gpx which is a track line following the coastline.
• Options -> Import -> GPX track
• Hidden folders are hidden in the file picker, but just start typing ~/.gpsdrive and hit enter. You should then see the tracks/ directory and be able to load australia.gpx.
• A red trace should appear along the coastline.
• Check that it lines up well with the coast as shown in map tiles of varying scale.

If a GPS is plugged in

• Make sure gpsd is running by starting "xgps" from the command line.
• The program will automatically detect gpsd and jump to your current position. This should bring up a continental map as you won't have any map tiles downloaded for your area yet.
• See the above "Downloading Maps" section to get some local tiles.
• If you have a local GPX track of some roads try loading that and making sure everything lines up, as detailed in the above "Overlay a GPX track" section.

That's it.

mb-system

• Open a terminal

cd /usr/local/mbsystem/examples/

List summary information about the contents of some bathymetric data files:

cd mbinfo/
./mbinfo.cmd

Grid some sample data and then view it:

cd ../mbm_plot/
./mbm_plot_5.cmd

# which creates this script:
./mbm_plot_test5.cmd

You should now see a nice plot of the seafloor off Baja California.

• (this also acts as a test of the GMT plotting package)

mapfish

Tested against ver 2.0

• Make sure you have a working internet connection
• Double click on the Mapfish icon on the desktop
• After a few seconds the web browser should open and you should see a map of the southwestern pacific
• Click the magnifying glass just under the word "Map" at the top of the map.
• Zoom in on Sydney
• Explore
