# New Image Web Server

Notification of new service from DELWP in May 2022:

Image Web Server and its storage have been migrated to the new AWS Cloud hosted Raster Data Platform and Image Web Server. This change is part of DELWP’s Spatial Transformation Program, which aims to enhance our service delivery capabilities including support of GDA2020.

New endpoint: https://iws.maps.vic.gov.au/erdas-iws/ogc/wms/RDP?SERVICE=WMS&REQUEST=GetCapabilities

...the existing Image Web Server service ( https://images.maps.vic.gov.au/erdas-iws/ogc/wms)...will be decommissioned by 30 June 2022.

# For Clients

Image Web Server account: http://images.land.vic.gov.au/iwsadmin/

Credentials for the Image Web Server: http://services.land.vic.gov.au/MyProfile/

If councils don't already have credentials, tell them to email coordinated.imagery@delwp.vic.gov.au.

Client credentials: https://github.com/pozi/PoziProxy/blob/master/lib/pozi-auth.js

# Troubleshooting

# Not all ecws within same aerial layer displaying

# Display order

When there are multiple ecws for the same aerial layer the ecw images are displayed as if stacked on top of each other, so the last image in a layer set will be the uppermost when displayed.

# No spaces allowed in ecw image layer set

When there are multiple ecws for the same aerial layer, separated by commas, no spaces are allowed before and after the commas. If there is a space then the ecw images after that point in the layer set will not be displayed.

# Get Layer Name

# Example 1 

\land\aerial\nth-grampians_2017feb03_air_vis_20cm_mga54.ecw

...becomes... aerial_nth-grampians_2017feb03_air_vis_20cm_mga54

# Example 2 

\land\aerial\towns\navarre_2016dec23_air_cir_10cm_mga54.ecw

...becomes... towns_navarre_2016dec23_air_cir_10cm_mga54

# Test Non-Password-Protected Layer

There is one layer on IWS which doesn't require any credentials: satellite_victoria_2000jan01_sat_etm543_30m_vg94

This could be useful for testing the proxy before we have to start applying credentials.
