NSW Land Data Webservices
NSW LPI has a number of spatial data services that may assist you in your research. April 2015 saw the release of the LPI Webservices, providing a mechanism to pull selected LPI data directly into your ArcMap session. There are currently (as at May 5th, 2015) six webservices available:
- NSW Imagery: a repository of standard imagery covering NSW, plus additional sourced imagery.
- NSW Imagery Date: a repository of the footprint standard imagery covering NSW, plus additional sourced imagery.
- NSW Base Map: a seamless statewide cartographic representation of NSW including roads, points of interest, localities, landform, drainage, cultural data, parks and forests, property boundaries and street address numbers.
- NSW Points of Interest: provides the identification and location of a feature, service or activity that people may want to see, know about or visit.
- NSW Administrative Boundaries: a dynamic map service of administrative, property and cadastral boundary dataset.
- NSW Address Location Service: allows the user to enter an address and it returns a unique and unambiguous identification of an address site and it’s coordinate.
(right click and ‘Copy link location’ for the WMS URL of each service)
There are two methods for connecting to these services…
Using an ArcMap Layer File
If you would like to add the NSW Imagery to your ArcMap session, LPI has provided an ESRI Layer file (v9.3) that will connect you to the webservice.
- Go to the NSW Imagery (MapServer) page.
- Click on the “ArcMap” hyperlink
- Save the file public_NSW_Imagery.lyr to your project workspace.
- Open or switch to an ArcMap session.
- Use the “Add Data” button to add the layer to the active Data Frame
If the layer method gives you a red exclamation mark in the ArcMap Table of Contents, try using the WMS connection method described next.
Using a WMS Connection
The layer file option hasn’t been working for some TOL users so this is an alternate connection option.
- Open ArcCatalog
- Expand the GIS Servers folder
- Double Click on Add WMS Server
` In the URL field add the following string:
– Leave Version on “Default Version”
– Leave User and Password blank and the Save Password box ticked
– Click on Get Layers
This will populate the boxes with the tree on the left and
the service details on the right:
- Click OK
- Under GIS Servers in ArcCatalog and ArcMap, you should now be able to see the connection
- Open ArcMap and add the BestImageryDates layer to the Data Frame
You now have the best available LPI imagery loaded into your Data Frame
It is important to remember that this imagery can change at any time.
If you need access to a particular image or year of imagery, remember, you can still come and talk to SAL Tech Staff about acquiring access to the imagery over your study area.
You may also want to load public_NSW_Imagery_Dates.lyr as this will give you information about the dates of the imagery in your area of interest.
As with all spatial data, don’t forget to…
Check the Terms and Conditions of Use for your intended use.
