Things have been progressing within the ICSM working group on GDA2020 and I thought I would provide an update as to where we are at:
On the 28th and 29th of November the GDA Implementation Working Group met and released some key communications about the datum. They are as follows: Continue reading
In my last discussion I introduced the topic of the new GDA2020 datum, the reasons behind it and how Esri intends to implement support for this new geodetic datum. Now that the impending initial release of the first set of parameters is due shortly and with the NTv2 grid due before the end of the year, I thought it important, that as an organisation, it is time consider how do you go about planning the move to this new datum.
So your organisation has decided it is time to purchase a drone. Drones are now at a price point where the return on investment is such that an organisation can purchase its own drone, invest in a pilot’s license and have imagery turned around at high resolution for small areas of interest in very short time frames. For many organisations a drone is an ideal supplement for the regular aerial imagery. It provides a mechanism to “see” changes almost as they happen.
At the end of September 2016, the Civil Aviation Safety Authority (CASA) regulations around drones will be further relaxed. Where essentially, organisations will be able to fly drones under 2kg without the requirement to have an RPA Operators Certificate (ReOC). See the announcement for more details.
An example of such a drone is Esri partner – 3DR – Solo quadcopter. When teamed with a Sony high resolution camera, it provides an ideal solution for those who need to capture imagery and elevation data that supplements their regular aerial surveys.
Esri recently released Drone2Map for ArcGIS. An application designed to take advantage of this new imagery from any platform and turn around usable information products for the whole organisation within a day of capture. As a minimum requirement, Drone2Map simply needs the imagery to be georegistered for X,Y,Z and it will do the rest for you.
Recently in the Australian media there has been a lot of commentary around the impending update to Australia’s primary datum. From GDA94 to GDA2020. It has even made the British media http://www.bbc.com/news/technology-36912700.
At Esri Australia this has prompted a lot of questions from clients in regards to the support of the new datum GDA2020 in ArcGIS. Will ArcGIS support GDA2020 and when will ArcGIS support GDA2020?
Before we start to answer these questions I think it is important we understand exactly what the new datum is and why Geoscience Australia is moving towards a new datum.
When the term drone is used it often conjures up images of installations being destroyed by laser guided bombs or unmanned military surveillance aircraft being used to spy on strategic targets. However, the drone of today is more than this. They have come down in price and size. To the extent that we can now purchase a drone or as CASA prefers a Remotely Piloted Aircraft System (RPAS), down at your local electrical store for a reasonable price.
In September CASA is introducing new regulations around the use of RPAS that make it easier for everyone to fly a RPAS. http://bit.ly/1sNxnt4 These consumer type RPAS will become more prevalent not only in the hobbyist field but also in the commercial field.
Esri is strategically placed to take advantage of this growing market. Recently released Drone2Map for ArcGIS (http://www.esri.com/products/drone2map) takes geolocated images from RPAS and creates professional imagery products for visualisation and analysis in ArcGIS.
So you’ve decide to go beyond the image basemap and extend your image service by adding some functions to your image service. You have NDVI’s, band ratios and band remaps available through your rest end point of your image service. Now how do you make these accessible to the end user?
So you’ve loaded your image into ArcMap and the image displays incorrect colour or there is no data values around the outside of the image that is masking crucial features in your map. How can you quick rectify these annoyances? Well this is where the Image Analysis window comes in handy.
Introduced in ArcMap 10.1 the Image Analysis Window is accessed from the Display menu in ArcMap . The Image Analysis window supports the analysis and exploitation of image and raster data in ArcMap, with a collection of commonly used display capabilities, processes, and measurement tools. Essentially all your image needs in one place.
